    Do It Yourself Solar Energy

    Edith Said:How to support yourself in the meantime? And would this business idea work?We Answered:First idea: You'd have to be sure each city would pay the $4,000 or the plan would fail. With Cali (and Nevada, where I am) on fumes for money, there's no guarantee the cities are doing any better. Second idea: All authors took a chance. Bottom line: Geniuses fail several times before they succeed. You don't bat 1.000 or everyone would never fail. The rewards are never reaped without certain risk. So figure out what your dream really is.Edna Said:solar power cars, government and the environment?We Answered:There are...

    Harnessing Solar Energy

    Bessie Said:1. How does solar energy compare with fossil-fuel energy...?We Answered:The energy in fossil fuel is primarily from solar energy. Using fossil fuel is a way of utilizing stored solar energy that was stored by plants such as phytoplankton, or in the case of coal, larger trees and plants, as well as small microscopic animals called zooplankton. As their bodies accumulated in sediment where there was little or no oxygen, they built up large quantities of stored solar energy in the form of chemical energy contained in the hydrocarbons that their bodies were made from. Eventually the organic material was...

    Hilda Said:How complicated is it to convert my house to run on solar power?We Answered:Solar power dependence is far more complex than meets the eye as few of these systems can produce sufficient electricity to meet daily needs unless the house is very small and the area is conducive to considerable sunlight. The popularity of these systems has ebbed and flowed over the past 30 or more years and has never really caught on despite many efforts of the government to provide incentives. There was a period between the 70's and 80's when solar power was used mostly for water heating...

    How Can Solar Energy Be Used

    Karen Said:how can solar energy be used as alternate source of energy ?We Answered:http://www.darvill.clara.net/altenerg/so… This is a favorite source of future energy for many people, comforted by the thought that it is unlimited. But, quite the contrary is true. The Sun will exist for a long time, but at any given place on the Earth's surface the amount of sunlight received is limited--only so much is received. And at night, or with overcast skies, or in high latitudes where winter days are short and for months there may be no daylight at all, the sunlight received is very limited at times....

    How Can We Use Solar Energy

    Terrence Said:By using solar energy, how long can we delay having an energy crisis occur?We Answered:If you want to put off having an energy shortage in the world using solar energy is the wrong approach. It would be much better to have more efficient transportation, buildings and industries.That would mean driving Toyota Corollas and hybrids instead of SUV's. It would mean better insulation in buildings.Solar energy (today) is not a very great way to get energy. It does not work well in much of the world like here in Canada in the winter. It requires allot of capital and takes...

    How Do We Get Solar Energy

    Shirley Said:Making most use of Solar energy?We Answered:Good question, it's because many in this country get into the mind set that if they can't get 100% out of something, rather than 70-80or 90%, ( and not just hot water ) than it's not worth doing; a very stupid and shortsighted concept.Kay Said:How do we get solar energy?We Answered:First, we can use the sun's energy to heat things--our houses, the water in our houses, the food in a solar cooker, and so on. This is called solar thermal energy. (Thermal means heat, so solar thermal energy just means heat energy from...

    How Do We Use Solar Energy

    Marcia Said:ways we turn solar into energy we use?We Answered:You can turn light energy directly into electrical energy by using photovoltaic cells (solar panels). These are what satellites in Earth orbit use, with those big flat panels. You can also use sunlight to heat water to turn a turbine. This is how some solar power plants out in Arizona does it-- An array of mirrors focus sunlight onto one spot on a heating tower where water is boiled by the concentrated sunlight. The steam is used to turn a turbine to turn a generator to produce electricity. Those...

    How Is Solar Energy Converted Into Electricity

    Jerome Said:How to harness electricity generated by solar winds?We Answered:Tesla's tower, perhaps? This is just another way we know that the solar wind is NOT electrically neutral, since the Earth has to absorb the energy and balance itself through the aurora act. Our instruments in space can't detect the charge difference because the solar "wind" (or electric current) is so big in its plasma state, and the difference per cubic meter is so small. This is why scientists like Phil Plait who ride on the nuts of big names like Einstein just might be wrong, but who are we...

    How Is Solar Energy Converted To Electricity

    Dora Said:How can heat be converted directly into electricity ?We Answered:Heat can be compared to magnetism or gravity. You need the movement or change of heat energy to generate electricity, just like you need movement or change of a magnetic field to generate electricity. You can generate electricity from DIFFERENCES in heat energy levels (Seebeck effect) If you're looking for a non-mechanical device, check out a Peltier junction. This is an array of dissimilar metals (thermocouples) that will generate electricity as heat energy moves through it. It is also a reciprocating device, meaning that if you put...

    How Is Solar Energy Generated

    Clifton Said:How much energy is generated from renewable/alternate energy sources?We Answered:Not a lot. I don't have specifics, but in terms of total US energy uses, renewable accounts for probably less than 10%, and most of that is hydroelectric. Wind power and solar account for very small fractions, and crop power is negligible -- mostly because most of that is ethanol from corn, which produces no net energy: it takes as much energy to produce a gallon of ethanol as it contains....

    How Is Solar Energy Produced

    Angel Said:How is solar energy produced?We Answered:I hope I can give you a decent answer. There are different forms of solar power: "solar thermal" and "solar photovoltaic". Solar thermal involves the sun directly heating a fluid, say air or water, which is then used directly, i.e. to heat a house or hot water for a shower. Solar photovoltaic, or "PV", as mentioned above, uses the sunlight itself. The light hits a PV panel made of semiconductors, which frees electrons which form a current. This is how we get electricity directly from sunlight. The brighter the light, the more power we...

    How Is Solar Energy Used Today

    Is Solar Energy Renewable Or Non Renewable

    Janice Said:non conventional sources of renewable energy here please...?We Answered:Geothermal electricity is renewable. Binary-Cycle Power Plants Hot geothermal fluid and a secondary (hence, "binary") fluid with a much lower boiling point than water pass through a heat exchanger. Heat from the geothermal fluid causes the secondary fluid to flash to vapor, which then drives the turbines. Because this is a closed-loop system, virtually nothing is emitted to the atmosphere. Dry Steam Power Plants Steam plants use hydrothermal fluids that are primarily steam. The steam goes directly to a turbine, which drives a generator that produces electricity. This is the oldest type of...

    Russell Said:Can solar energy every make oil/gas obsolete?We Answered:Solar power has the theoretical ability to displace energy from fossil fuels but in practice there are other issues. 1) Solar power must be harnessed. To do this requires materials, some of which are currently made from petroleum. 2) Fossil fuels are also the feedstocks for many of the products we use in everyday life. Plastic and chemicals are usually from oil. In practice, solar power could displace our energy dependence on fossil fuel much more easily than the demand for oil as a chemical feedstock. I've heard that at a long...

    Solar Alternative Energy

    Kent Said:How Solar cell could be an alternative energy toward fossil fuel ?We Answered:Fossil Fuels are used in power plants to create energy for your home, or in certain vehicles to create motion, such as in a plane. These fuels are burned to create heat, which makes steam which turns a turbine, connected to a generator. The largest problems with fossil fuels are that they take millions of years to be made, release toxic gases, and the efficiency of the entire process is maybe 3%, meaning that three percent of the energy in the fossil fuels are converted to electricity....

    Solar Electrical Energy

    Lester Said:How do solar FARMS convert solar energy into electrical energy?We Answered:Hey Me, there are 3 basic types of solar farms. The first, built in the 70's used large mirriors to focus sunlight on a boiler that made steam with the heat. The steam was then used to run a steam turbine generator. It worked pretty well when the sun shined. The second was the photovoltiac farm, using solar electric panels. These type panels use silicone layers to convert the incoming photons directly to a voltage. They are simple and generally maintence free, but very expensive for the amount of...

    Solar Electricity Energy

    Betty Said:what is the best efficiency of solar-to-electricity energy conversion that one has achieved till now?We Answered:Efficiency of photovoltaic energy depends on many factors: - Wavelength of Light: When light strikes the surface of a solar cell, some photons are reflected and do not enter the cell. Other photons pass through the material, some are absorbed but only have enough energy to generate heat and don't create charge carriers - Recombination: Charge carriers—which are electrons and holes—in a solar cell may inadvertently recombine before they make it into the electrical circuit and contribute to the cell's current. - Natural Resistance: The natural resistance...

    Solar Energy Cars

    Antonio Said:Can solar energy car have wind power combine together to give us extra energy?We Answered:Yes, but you only get to combine their energies when both sunlight and wind are available. If wind is calm or blowing the wrong way, the solar cells must do more work to carry the extra load of sail. If the sun ain't shining, the sails must drag the extra weight of solar panels. The best solution is to use the solar panels as sails when the wind blows and make them more streamlined when the wind is unfavorable.Raymond Said:Cars on solar energy?We Answered:There are...

    Solar Energy Cell

    Roy Said:Where can I find info on solar cell?We Answered:Solar Cells Solar cells (as the name implies) are designed to convert (at least a portion of) available light into electrical energy. They do this without the use of either chemical reactions or moving parts. History The development of the solar cell stems from the work of the French physicist Antoine-César Becquerel in 1839. Becquerel discovered the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution; he observed that voltage developed when light fell upon the electrode. About 50 years later, Charles Fritts constructed the first true solar cells using junctions...

    Solar Energy Centre

    Joanne Said:Why cant we harvest the heat of the centre of the earth as energy?We Answered:Geothermal is the right term; in some places, we do use geothermal energy--the problem with it is that this form of energy is very geography-dependent. In places where the heat from the center of the earth vents out on the earth's surface, such as geysers. A heat vent ideal for energy conversion is stable and predictable, and releases a lot of energy--this just doesn't happen in most places. Where geothermal energy is available and efficient (such as The Geysers, in California),...

    Solar Energy Efficiency

    Diana Said:Could electrical engineers be associated with solar energy?We Answered:Yes. A solar energy project is primarily electrical and structural. The d.c. output of a solar array needs to be inverted to a.c. and transformed to the voltage of the grid. There are also protective relaying and a system to synchronize the inverter output to connect to the grid. This also poses potential problems with system dynamics. When clouds suddenly shade the sun, the energy of the solar array is immediately reduced and needs to be backed up by other sources. If solar energy, wind...

    Solar Energy Forums

    Lance Said:Global Warming - basic calculations?We Answered:Crude oil contains about 6119 megajoules (MJ) per 42-gallon barrel. Pure unblended gasoline contains about 130 MJ per gallon, less if its an ethanol blend. One metric tonne of coal contains 24,137 MJ. http://www.eia.doe.gov/kids/energyfacts/… Above the atmosphere, the Sun's energy contains about 1365 Watts per square meter, when that square meter is at right angles to the Sun's rays. (One watt is one joule per second.) Down here on the ground, you have to contend with clouds and dust, and atmospheric scattering, so you're lucky to get 1000 watts per square meter. So theoretically, a one-square-meter area that...

    Solar Energy Fossil Fuels

    Dolores Said:How many years will it be before we use solar energy instead of fossil fuels ?We Answered:People have already been using solar for decades. Google, for instance, just covered the rooftops of their headquarters with solar panels last year. They figure this will cut the electric bill of those buildings by about 20%. The big problem with solar is that the equipment is expensive, which makes the return on investment (ROI) quite long. For instance, you can get a similar installation of solar panels on your roof like Google. Even with state and national rebates to help...

    Solar Energy Generating Systems

    Shane Said:Question about the big bang and the kinetic energy generated by it?We Answered:According to calculations based on known physics, the so-called big bang was a sudden expansion of space-time with no matter contained in it. At some point very soon after the expansion began, the density of the energy that filled space-time dropped below a certain level and some of the energy began to "condense" into sub-atomic particles. After 3 minutes or so, the energy density of the Universe, (or temperature if you like) dropped enough for sub-atomic particles to start forming protons and neutrons. These...

    Solar Energy Generation

    George Said:Before Einstein, gravitational contraction appeared to be a plausible mechanism for solar energy generation.?We Answered:Before Einstein, energy conversion was not well understood and one of the theories for Solar Energy was as a result of gravity compressing the volume of the Sun as a means to make it heat up and shine. Science had already pointed to an age for the Earth of millions or hundreds of millions of years, and science had no way of explaining how the Sun could be powered for that long of a time. When Einstein figured out how energy could be released in nuclear reactions,...

    Solar Energy How It Works

    Tammy Said:how long will it take solar energy to work on earth?We Answered:Solar power works-it is used in many places. The question is one of economics, which underlies nearly every human activity, but is one of the least studied fields. It is expensive, and energy-intensive, to make solar-powered electrical panels-which in any case only work well inbright sunlight. Solar power is most useful for heating water in individual houses, but again, it isnt economically competitive with coal, oil, and natural gas. In order for solar power to be widely used, a number of things would have...

    Solar Energy In Australia

    Claudia Said:is solar power likely to be useful in australia and across the world in the future?We Answered:Solar Power is already gaining steady use in both Australia and world wide. However, it is not likely that it will become the only power source as the sun is unpredictable and not as consistant in every country. Several countries, territories and states have very little sunlight during the winter months. Having said that, it will more than likely, begin to gain popularity as the years go on and as money becomes available to install the solar panels in the...

    Solar Energy Kwh

    Lawrence Said:How much energy do 5KW solar panels roughly create in KWH/Day?We Answered:It depends on where you are, how many sun hours are available. Sun hours are the number of hours that equals the standard test condition that panels are rated at. This number changes throughout the year with the seasons, but you can find an annual average and use that number. A nice average is 5 hours. 5kW x 5 sun hours = 25kwh (kilowatt hours).

Meanwhile, China, India and the rest of the non stupid liberal world...

    Solar Energy Market

    Heidi Said:Why aren't alternate fuel powered vehicles introduced in the market rather than screaming on climate change?We Answered:The problem with introducing the vehicles to the market is that there are not many places one can refuel. If the nearest facility to get fuel is a hundred miles away from your home, would you invest in a hydrogen powered car? Manufacturers will not want to spend time and money building these cars if there is no one out there who will buy them. If we are to see the increased use of these vehicles, it will me in the commercial vehicle market,...

    Solar Energy Materials & Solar Cells

    Brad Said:Is there any clear materials that solar cells could be made out of?We Answered:If it was truly clear there would be no photons absorbed and converted to electricity. That is to say, all the energy would pass though the material. You could have a translucent materiel for some colors though. As a matter of fact, silicon, the most common material used to make solar cells is transparent for some of the infrared wavelengths.Claudia Said:Materials that are high conductors of Solar power?We Answered:There is no 'conductor' of solar power. Solar power is either converted into electricity or heat. If your...

    Solar Energy Materials And Solar Cells

    Scott Said:Did you read about the 100% efficient Solar Panel?We Answered:Your article states, "...This combination of materials also utilizes the entire visible spectrum of light energy, translating into a theoretical potential of almost 100% efficiency..." Current solar cells only use a portion of the visible spectrum, but none utilize 100% of ANY portion of the spectrum. It appears to be a pretty big leap to go from a full-spectrum panel to a 100% efficient full-spectrum panel. One curious thing to consider, a 100% efficient panel would appear pitch black, but never get warmed in the sun.Richard Said:Sci-fi/fantasy novel - Energy, everywhere!?We...

    Solar Energy Materials

    Kristin Said:solar energy is energy that is transferred from warmer to cooler materials?We Answered:That sure is a valid statement but it ain't no question.Rafael Said:What materials conduct the most solar energy?We Answered:Air conducts solar energy because it allows it to pass through. For a solar cooker you want to deflect or concentrate the solar energy, and maybe focus it onto something that absorbs the energy to create heat. To deflect, you need a reflective surface, something with low emissivity and high reflectivity. To absorb you need a dark or rough surface, high emissivity, low reflectivityChristopher Said:how to construct a model to...

    Solar Energy Meter

    Erin Said:Solar energy constant at 50 degrees north?We Answered:The height above the ground isn't really a major factor in the calculation. It's much more important to know the time of the day and the season. Example: The maximum amount of irradiance would be received at the summer solstice (June 21), when the angle between the sun rays and the vertical would only be (50-23.5)° = 26.5°, therefore the irradiance would there be sin(26.5°) / tan(26.5°) * 1.2 kW/m² = 1.1 kW/m² That's the maximum value. On the winter solstice (December 21) though, the best angle you get is (50+23.5)° = 73.5° Therefore, the...

    Jennifer Said:Solar energy sent down to Earth?We Answered:How plausible this concept is something that I am not at liberty to say, since I am not all that well versed in the subject. What I can say is that, assuming this system of energy production is viable, it will probably be obstructed because of the deeply entrenched interests most of our politicians have with the oil and gas lobby. Why do you think, given all of our technological advancement in other areas, the movement away from fossil fuels has been moving at a snails pace. It is certainly not for lack...

    Dora Said:Regarding power / energy usage: How can I get off the grid?We Answered:There is no reason to go 100% off the grid, you can install systems that will offset part of your energy usage. I have a solar system that offsets about 75% of my electricity. I may add to it at a later date, but I got a system that maximized my rebates. I am also using a fraction of the energy that a typical home uses by implementing many energy conservation methods. Reduce standby energy with power strips, energy star appliances, maximize energy efficiency of my heating...

    Solar Energy Notes

    Anthony Said:solar cells capacity?We Answered:That cost does seem high. Here in San Jose, California in the United States I have several colleagues that have purchased solar photovoltaic systems for their homes. The systems are advertised as capable of producing up to 3,000 watts under ideal conditions. However they actually produce substantially less than that. My colleagues experience is that annual production has been running approximately 4,000 kilowatt hours per year. That is not enough electricity to run a home. The system is designed to feed electricity back into the grid if the system is producing more electricity than the home is using, which seems to...

    Ricky Said:Solar pool heating in the state of Pa. How effective?We Answered:Here in the northeast, I've seen people use the bubble wrap style covers with moderate success. What looked even more promising is a long coil of black hose which hooks into the pump. As water is drawn from the pool, it is circulated through the very hot hose, filtered, and then returned back to the pool. It seemed to work well and is a very simple and effective way to heat the pool in a green way.Laurie Said:Any nice DWF in Phoenixville to Norristown, PA areas?We...

    Solar Energy Panel

    Nancy Said:can we use solar panel around the rocket so that it can work using solar energy?We Answered:NO we can use solar panel for satalites not for rockets. A rocket or rocket vehicle is a missile, aircraft or other vehicle which obtains thrust by the reaction of the rocket to the ejection of fast moving fluid from a rocket engine. Chemical rockets work by the action of hot gas produced by the combustion of the propellant against the inside of combustion chambers and expansion nozzles. This generates forces that accelerate the gas to extremely high speed and exert a large...

    Solar Energy Panels

    Rose Said:Can solar panels catch any energy from the sunlight reaching under the surface of oceans or rivers?We Answered:Solar light do not penetrate very deep in water, therefore the efficiency of any solar panel would be extremely low. This means bigger panels, and extra cost. Moreover, even if I cannot give you a precise estimate of the power consumption of a submarine, it is likely to be much higher than a car. And solar cars are, at the moment, quite unpractical. They would need huge solar panels.

    Solar Energy Passive

    Marilyn Said:what is passive energy?We Answered:Passive solar energy is simple unaided sunshine heat and/or light. Feel warm from standing in the sun? That's passive solar energy. It's doing nothing but landing on you, and warms you up directly. Sunlight is passive solar light. Active solar when there's an appliance of some kind turning that passive energy into some other kind of energy. The most obvious is sunlight landing on a photovoltaic cell which produces electricity, and you use that electricity to do something like create heat with a toaster to make toast, or to light a LED lightbulb to make light....

    Solar Energy Plant

    Andrew Said:Question about solar energy plant?We Answered:Depends upon the city but you have to understand solar power like wind power is an intermittent power source and without a battery backup you cannot directly power anything! Solar power is best suited for power needs off-the-grid where homes can be powered with 12 volt DC systems and back up batteries. Once you go to normal household Ac voltage 110 or 220 you have to put the power through a inverter which can rob up to 20% of your power. Using standard solar panel's it adds up to allot of panels! As for cost...

    Solar Energy Plants

    Kim Said:Are there plans to build Solar energy plants and wind farms on the same land?We Answered:Of course its possible but think about it: You want to locate wind farms where it is consistantly windy most days of the year and the stronger the winds are the better. OTOH, you want to locate solar panels where the sun shines longest and strongest. These two conditions are rarely co-existant. Wind farms located off the coast of Massachusetts generate a lot of electricity but are frequently in overcast conditions. The sun shines strong in the desert but the air is nearly calm...

    Solar Energy Power Plant

    Patsy Said:If I have a one mega watt solar power plant and selling the energy for .20 cents how much will that generate?We Answered:If the panel is running at full capacity it will produce 1 MW which is 1000 kW. For every hour it is running you will get 1000 kWh. Therefore, for every hour it is running you will make $0.20/kWh x 1000 kWh = $200. Keep in mind that the panel will only get at most 10 hours of sunlight, and that most of the time it won't be running at peak capacity due to cloud cover, angle...

    Solar Energy Renewable Resource

    Jose Said:Which of the following is a non-renewable energy resource?We Answered:Your teacher screwed up. They're all renewable. The answer s/he's probably looking for is natural gas. However, any time you have cellulose decompose in the absence of Oxygen you get natural gas. So if wood (not listed) is a renewable energy source then so is natural gas. Also, if s/he is going to baulk at that answer explain that the sun has a finite amount of fuel and will eventually burn out. So technically solar power is not renewable. Wind is generated (ultimately)...

Hydro is from the evaporation of sea water and the subsequent precipitation at higher elevations. Fossil fuels are the solar...

    Solar Energy Report

    Marsha Said:Does Solar energy form emit greenhouse gasses or other polluants?We Answered:Solar energy creates pollution in the creation of the actual solar cells. However, this pollution is much less than normal methods of producing power (see first link). The energy created by solar power is pollution-free as it works on the photo-electric effect, which just pushes electrons around rather than emitting anything (see second link). I'm also assuming you're talking about photo-voltaic solar cells. They do have other, newer cells that simply focus sunlight to heat water, and I'd imagine the pollution is similar to photo-voltaics, though I have no...

    Solar Energy Source

    Raymond Said:what is the most and least expensive energy source? solar,wind or geothermal?We Answered:It totally depends on the scale and location. What you need to understand is that if you double the amount of solar (PV) panels you get double the energy. If you double the size of a wind turbine blade you get FOUR times as much, and if you double the average wind speed you get EIGHT times as much. And Geothermal is still an emerging technology (compared to solar and wind anyway). So BIG wind turbines on a very windy location is probably the best right now. But equally...

They are a mature technology, so there is unlikely to be any ground-breaking innovation in this area. Green energy stocks on the other hand, as your long list suggests, are in many different technologies and are not fully developed. Therefore, as Oil and Gas are immediately available, while green energy is still to fulfil its potential, I don't think that there is the correlation you suggest. Once these new power sources become as plentiful as oil, they would be inversely correlated,...

    Solar Energy Storage

    Kirk Said:In a solar energy set up with battery energy storage, how many batteries does it take to run a 2200 SF house?We Answered:Peter is correct regarding energy use. To get your answer you would need a professional energy audit from a small wind & solar contractor. It's most likely that contractor will recommend significant energy efficiency upgrades for your home as with most homes it's far cheaper to upgrade to high efficiency appliances than it is to install additional energy storage capacity.Hazel Said:Why are "Molten Salts" a good solar energy storage media?We Answered:http://www.eere.energy.gov/states/altern… http://www.physics.metu.edu.tr/~ecevit/p… http://www.nrel.gov/docs/fy99osti/24649.… http://www.osti.gov/bridge/purl.cover.js… http://www.sandia.gov/Renewable_Energy/s… http://home.earthlink.net/~bhoglund/what… http://www.patentstorm.us/patents/705152… <edit> Here's another link searching...

    Julian Said:Stored solar energy in the form of buried vegetation that floueished in sunlight is represented by what?We Answered:This question confused me a bit but what I think you are asking is how does solar energy eventually end up stored in vegetation under the soil. OK.. Plants undergo photosynthesis to store energy in cells call chloroplasts. when the plants are buried, they still have that energy stored in their cells. Over thousands of years they are compressed and some release gasses (methane deposits- a large source of natural energy) the solidified remnants are later mined as coal. For more information on that...

In theory they can be made reasonably efficient and so you could get a nicely closed system where the energy circulates endlessly. BUT.....it wouldn't do anything useful for you. For light form street lights to serve some purpose, the light has to hit things. It has to be reflected off the roads and berms and people and footpaths..... and not get collected by efficient solar panels. You might think that recycling at least a bit of...

While it is possible we might see some relief in the price of gas, I don't think it's ever going to go down very much. We really need to make the commitment to shift to more renewable energy sources - rather than just being a politically correct thing to say and do. In fact, I think the government should strongly encourage the oil companies to pour large amounts of...

    Solar Panels Energy

    Thomas Said:Wind turbines, generators driven by waves/tides and solar panels take energy out of the environment. Has?We Answered:Hey Chris, Sam is correct. The use of a wind turbine for example, has such a small effect on the local wind patterns. How much? Did you know the most efficient wind turbine in the world is 37% efficient? That means two thirds of the wind that goes through it's rotor is unnaffected. There is enough wind energy in North and South Dakota to power the entire US power grid, even at 37%. But beyond that, even...

    Solar Power Companies

    Dwayne Said:do you think the power companys will try to recoup there lost profit from all the people going to solar power?We Answered:If the demand for electricity from the power company decreases, the law of supply and demand states the price will also decrease. If demand goes up and up, they can pretty much charge what they want, except most if not all states regulate the power company. So the theory that they will recoup lost profits from those customers who don't switch to an alternative form would run counter to current economic theory. If they tried...

    Solar Power Cost

    Stephen Said:Solar power how much does it cost per watt to install today and?We Answered:Solar panels by themselves are about US$4.50 per watt. You might get a 'deal' at slightly over $4.00 per watt if you buy a large quantity. So, if you want a 3 kW system, that's between $12,000 and $13,000 just gor panels. Installation costs go up from there. A proper inverter could run $1000, and batteries are about $50 - $100 each for deep-cycle types (you will want at least 10 of those). Labor for installing everything from a licensed electrician could also run...

    Solar Power Energy Source

    Francis Said:if we can turn solar energy in to a power source then why cant we harness gravity???????We Answered:besides the ways that already exist, there are no materials that respond to gravity in a chemical way. Solar panels react to the radiation and other factors in light.Wade Said:why is solar power an alternative source of energy?We Answered:Because when you you use solar power --which is a renewable energy-- you don't release carbon dioxide emissions in the atmosphere unlike traditional petroleum or coal based electricity which harms the earth. Therefore it is the more environment-friendly alternative source of energy.Floyd Said:What is...

    Solar Power Generation

    Antonio Said:How Electricity Generation Works in solar power?We Answered:Solar power (photovoltaic or "PV") cells are silicon wafers that are 'doped' so that when sunlight hits them, electrons are knocked loose to create electrical current. They usually provide very little voltage (1.5 to 2.5 volts), but are connected in series to step the voltage up to 24V. The array of cells is usually connected to an inverter, which changes the 24V direct current (DC) into 120V alternating current (AC) that we are used to in the homes. The home is then either also tied to the grid in a...

    Solar Power In

    Daniel Said:What are some differences and similarities in solar power and nuclear power?We Answered:Solar power has a relatively low capacity factor, on Earth it is not sunny all of the time. Nuclear fission power plants have a very high capacity factor. Both power plants are expensive to build and expect return on investment over the life of the power plant. Both produce energy according to E= MC squared, the sun is fusion powered, while nuclear power plants are fission powered. Fission plants require Uranium fuel which has to be mined/refined, solar panels require chemicals and metals which need to be...

    Solar Power New York

    Misty Said:Can you run a home entirely on solar power in New York?We Answered:It would cost many tens of thousands of dollars. And it doesn't work well in the winter, for obvious reasons. And let's not forget, those dollars that you pay to buy the solar equipment, represent energy used, to EARN those dollars. This is always ignored when people talk about solar, and it's why it really doesn't pencil out at all. To give you an analogy, if take a semitruck across the country, burn thousands of gallons of gas to get there and back, to buy one fluorescent bulb to replace a...

    Solar Power Renewable Energy

    Luis Said:Which renewable energy source (solar, wind, hydro, etc. is the most efficient (most power for the lowest cost)We Answered:Clearly it is hydro - far more energy is currently being derived from it than any other renewable source, and since economics is the driving factor, it must be the cheapest per kilowatt-hour. BTW, that is not necessarily the most efficient - efficiency is power out divided by power in. But hydro is definitely doing pretty well in that catagory too, if not overall the most efficient. I would guess it's the best of the 3, with wind...

    Solar Power Technologies

    Calvin Said:why should we switch to solar power?We Answered:It will be cheaper for us in the long run. The market dictates cost for natural gas, coal etc. No one will be buying or selling sunlight, so once a system is in place the only increases will be labor and to fund more projects. It's true that solar can't be a stand alone solution, but currently the majority of the electric grid is a mix of sources, so we will just continue with that practice. The fact that no one will be able to manipulate prices is also the reason so...

    Solar Renewable Energy Credits

    Rhonda Said:If McCain cares about the environment, why does he oppose renewable energy?We Answered:I don't buy into McCain's claim at all, McCain has absolutely no solid history of supporting truly clean energy sources. I agree with all of the sources that you have selected pointing to the fact that John S. McCain does not really care about the environment except to get votes. It is clearly the trend for politicians to say that they care about the environment in order to win, if any politician runs on a policy that completely ignores the environment they will surely lose. McCain's positions...

How does one add/remove excess thermal energy?We Answered:ha ha i thought about that, 'why not build giant solar panels in space to block off the sun, since our polar ice cap just isn't cutting it anymore'. we dont have the technology simply put. theres probably a huge matter of safety in transfering the energy if it was possible. we need to focus getting heat from the sun away from our planet as it is. worrying about substituting energy wont help us at this point.Rose Said:What thoughts on mass scale geo thermal energy?We Answered:Geothermal energy in the...

    Solar Thermal Energy

    Jacqueline Said:Why aren't we using solar/wind/geo-thermal energy???We Answered:We are not using them because they are not efficient enough yet. Solar panels are still only 40% efficient at BEST sorry but the return on the cost is just not high enough. Wind power is getting used more and more often it's just not wide spread yet because not all areas are windy enough for it to be used. Geo-thermal really has no excuse because almost anyplace can use the benefits of Geo-thermal, but not Geo-thermal Energy production. Simply Geo-thermal energy use like Ground-source heat-pumps.

    Statistics On Solar Energy

    Yvonne Said:What are my chances (very good, good, fair, or poor) of getting into MIT?We Answered:You sound like an excellent candidate, and I'd say your chances are good, but not certain by any means. The truth is, a place like MIT has many, many, excellent candidates and sometimes their decisions are almost coin tosses. It appears you are ethnically Indian, which puts you in the unfortunate category of being in one of the most statistically overrepresented ethnic categories, so it works against you as they might be just a tad more eager to get someone with your stellar...

All the deep space (Jupiter and beyond) probes use radioisotope thermal generators....

    Sun Solar Energy

    Bradley Said:Why cant we use trees to capture solar energy from the sun and then recover the energy from the trees?We Answered:Photosynthesis generally takes light, CO2 & water and makes sugars. These sugars are chemically converted in to food, propane, methanol, ethanol, coal, oil, wood and all the other fossil fuels and orgnic compounds on the earth, through natural, geologic, and/or manmade processes. At every step of each process, energy is lost. To gain usable energy, other than in biologic processes, requires burning something, and using the expansion of heated gases to create physical force (motion), or...

    Sunlight Solar Energy

    Angela Said:what are the different principles based on which electricity can be produced using SUNLIGHT(SOLAR ENERGY)?????We Answered:Photo-voltaic Heat Indirect via heat Burning vegetation Fossil fuels Sunlight is white because it contains photons of a broad range (spectrum) of energies i.e. colours. So your question might be re-stated as "What are the different principles for solar energy suited to the different colours within sunlight?" The obvious one is photo-voltaic cells that directly convert light into electricity. That covers the visible spectrum. High-energy light, i.e. ultra-violet is best converted to electricity by using it to generate heat (infra-red) which then can be converted into electricity with the use...

    The Solar Energy

    Glen Said:why does solar energy extraction NOT take place at the equator?We Answered:The equator isn't the hottest place on earth, it just gets the most direct sunlight at the top of the atmosphere. Near-tropical desert areas are hotter and get more sun at ground level due to less cloud cover. In addition, there are the questions of local demand for energy and local economic surplus to build solar power installations. There are some solar power installations in equatorial countries.Marlene Said:What impact does solar energy have on people, animals and the environment?We Answered:The sun's energy, when converted through photovoltaic cells, has...

    Thermal Solar Energy

    Gail Said:Explain each of the following alternative thermal energy sources: Solar, Wind, Hydro, Compost, Geothermal.?We Answered:Geothermal and solar are the only "thermal energy sources". Geothermal works by generating electricity from heat deep underground, usually near active volcanoes. Water is pumped down, then turned to steam which comes back up and drives a turbine. http://en.wikipedia.org/wiki/Geothermal_… There are solar thermal power plants out there, but they are not very common and this is usually not the technology people mean when they say "solar" energy. Most of these applications involve using large mirrors to concentrate solar energy, and heat up water to drive a...

    Types Of Solar Energy

    Naomi Said:Types of solar energy?We Answered:One way to categorize solar energy is by how it is converted into useful forms. There are two types in this category: Passive Solar Energy and Active Solar Energy. Passive Solar Energy doesn't use mechanical means to collect, store, or distribute the solar energy. For example, a thermosyphon (solar water heater) will use natural convection to circulate the water through the system. Active Solar Energy uses mechanical devices to collect, store, and/or distribute the solar energy. For example, active solar water heaters use pumps to circulate the water or heat-transfer fluid in the...

Solar panels capture sunlight but from what I know they capture less than 40% of the energy from it. Additionally when there is no light you have to rely on betteries with stored energy. As it improves I'm sure it will be distributed and implemented more.Deanna Said:What are the different types of storing...

    Uk Solar Energy

    Monica Said:How much Government spending goes into R&D of Renewable Energy?We Answered:Way too much. We have spent billions of dollars on subsidies and research into 'alternative energy' over the past 30 years and are essentially still in the same spot. The fact of the matter is that unless we raise energy prices to the point where our economy is crippled and people freeze to death in the winter - alternative energy will never be viable.Clyde Said:Which country in this world has the largest output of solar powered generators for electricity ?We Answered:Well, presently it might be Germany, but it was just a...

    Usa Solar Energy

    Michele Said:If the USA became more energy independent would individual income per capita increase as in other countries?We Answered:I think your data is skewed. There are very few countries that do not rely on oil. Iceland is the only one that comes to mind. The reason we have become dependent on foreign oil is that buying oil from other countries was seen as the cheapest way to get energy. Had we made the investment in alternative energy sources, our per capita income would have been lower, not higher. Even now, at oil's high prices, solar, biofuel, etc. are still generally more expensive...

    What Are Some Advantages Of Solar Energy

    Louis Said:science help with solar energy!?We Answered:Solar cells are totally silent. They can extract energy from the sun without making a peep. Now imagine the noise that the giant machines used to drill for and pump oil make! Solar energy is non-polluting. Of all advantages of solar energy over that of oil, this is, perhaps, the most important. The burning of oil releases carbon dioxide and other greenhouse gases and carcinogens into the air. Solar cells require very little maintenance (they have no moving parts that will need to be fixed), and they last a long time....

    What Are The Advantages Of Solar Energy

    Cheryl Said:Solar Energy vs Fossil Fuels??We Answered:The main disadvantage of solar power is scale. There simply isn't enough energy available from the sun to even come close to meeting our requirements; in North America the sun delivers an average of 1300 watts per square metre at noon. Solar panels convert just 15% of that energy to electricity meaning it would take a panel measuring 1km by 2km to deliver the same amount of power as a single nuclear reactor and it would only deliver that much power for a couple of hours per day. By using solar...

    What Is The Solar Energy

    Jack Said:Is Solar Energy really feasible in future both technologically and economically?We Answered:It's technically feasible already and it's close to economic in very sunny areas. The problem right now is cost, but that is going to fall. Then we hit another problem; and that is that the current cheapest technologies rely on rare materials. Thin film cells rely on indium, gallium or tellurium, and dye sensitized cells rely on ruthenium (although only in tiny amounts, I calculate the USGS' estimated producible Te to be equivalent to about 17GW/year of solar power. Add in the Ru, In, Ga and you're looking at...

    Where Does Solar Energy Come From

    Lester Said:where does solar energy come from?We Answered:Generating electricity with the power of the sun’s rays (“solar power”, “photovoltaic power”, or “PV” for short) is possible due to the photovoltaic effect. “Photo” comes from the Greek for “light”; “voltaic” refers to the production of electricity and is a variant of Italian physicist Alessandro Volta’s name. To illustrate how PV works, let’s follow the flow of energy through a small grid-tied residential system: The first step in the process occurs when rays of light from the sun strike the cells within PV modules (modules are commonly called “panels”). As the...

    Why Is Solar Energy Good

    Derek Said:Why is solar energy good for Earth?We Answered:The Earth (as a planet) is indifferent to the solar energy. If you meant solar energy for people, it is an additional (very expensive and not productive) source of heat and electric energy. Solar energy production industry can not survive on its profit, it need subsidiaries from government (people taxes). Lots of it! It is not any cleaner then other types of energy resources. The development of solar power batteries is very toxic and has a lots of toxic waist. The solar batteries have to take a lot of space to produce any...

    Why Is Solar Energy Important

    Julian Said:why are rain and solar energy important inputs into a woodland ecosystem?We Answered:Generally rain and solar energy (sunlight) are the only inputs to a woodland ecosystem. They support the growth of the plants and trees which in turn support all the other life (e.g. bacteria, worms, nematodes, fungi, insects, animals). These other life forms also use rain and sunlight directly. Trees and plants also use nutrients in the soil to help in their growth but these nutrients are recycled when the plant or tree reached old age and dies. Woodland ecosystems are so efficient at converting rain...

    Why Is Solar Energy Renewable

    April Said:Renewable energy - why aren't we getting more help?We Answered:The renewable energy people must not be bribing the right politicians to enact the laws that would benefit that industry.Oscar Said:If renewable energy is the keystone of Obama's energy plan, why is Congress abandoning Obama's clean energy?We Answered:Congress realizes those wind/solar farms might end up in their backyard. It's time to put Nuclear back on the table -- we have a plant up the street in San Onofre, CA and the technology has advanced immensely from the 3-mile/Chernobyl days. http://www.sce.com/PowerandEnvironment/P… The San Onofre Nuclear Generating Station (SONGS) is jointly owned by Southern California...

    Why Solar Energy Is Important

    Emily Said:How are solar homes constructed?We Answered:Solar homes are generally oriented so they have a lot of window with a high U value and a large area facing south, Sarah. They typically have fewer, smaller windows on the east and west sides, and still fewer on the north side. This orientation ensures the house will pick up as much heat as possible in the winter months - think of a greenhouse trapping the heat of the sun. The summer sun is much higher in the sky, and the house's design prevents excessive heat gain in the summer by using awnings...

    Why Solar Energy

    Carl Said:What are three reasons why solar energy is not completely converted to chemical energy by primary consumers?We Answered:Primary consumers are herbivorous animals like deer, rabbit etc. They cannot convert solar energy directly into chemical energy. If you are asking about the conversion taking place in plants, which are called as producers, major part of the solar energy is reflected back and not absorbed. Even then absorbed, some percentage is converted to heat and only the remaining is converted to chemical energy. This is governed by the second law of thermodynamics. According to this law, no form of energy can be converted...
