what is the importance of solar energy? ?

We Answered:

Most available renewable energy on Earth. It is cheap. Can be generated at home. It does not cause any pollution and no harmful effects.

This site can help you get more information about it.

the livescience link is sorta neat, but you have to wait through a few minutes of junk

wt acording 2 u is d importance of non conventional sources of energy in recent years ????

We Answered:

A combination of renewable energy will be required for a sustainable future. No one technology has the ability to meet all energy requirements. An effective combination of many technologies will be required to meet future energy demands. Each technology has it’s advantages and limitations, but together, they can solve the world energy crisis.

Cleaner alternatives include
- Hydroelectricity
- Wave power
- Solar energy
- Wind power
- Biofuel

Other alternatives such as nuclear can be used as a transitional technology to help our society move away from fossil fuels and towards renewable energy. Clearly nuclear energy also has many concerns and is a limited resource, but technology can be used temporarily while we further develop more sustainable energy sources.

The key point is we need the combined effort of individual support and government support and funding. A combination of renewable energy sources can easily meet societies energy requirements if we invest enough research, time and capital into it.

The best way to regulate the effects of increasing energy consumption is through a combination of regulation, international agreement, and green res each and technology initiatives.

The introduction of tighter regulations for large industries and high energy users should be used to control and regulate energy consumption. Perhaps placing a tax or fees on excess consumption.

International agreements to reduce emissions. Such as the Kyoto Protocol. And international carbon trading schemes.

But most importantly, is the source of energy. If we invest in green research initiatives and prevent the production of dangerous pollutants, then rather than policing energy consumption, we can focus on more sustainable energy alternatives such as wind, hydro, solar, geothermal, etc.

No single method will be effective in controlling energy consumption. Rather, it will be a combination of policy changes and a societal & technological shift towards more sustainable alternatives.

Each technology has it's advantages and limitations. But no single method will be effective in controlling energy consumption. Rather, it will be a combination of policy changes and a societal & technological shift towards more sustainable alternatives. Australia and other countries need to impliment a combination of renewable energy plans.

what is the importance of solar energy and why do people use and where does it come from?

We Answered:

This is suppose to be common sense by now well unless you're 6 yr old then that's different. So I guess you need read this:

solar energy, any form of energy radiated by the sun, including light, radio waves, and X rays, although the term usually refers to the visible light of the sun. Solar energy is needed by green plants for the process of photosynthesis, which is the ultimate source of all food. The energy in fossil fuels (e.g., coal and oil) and other organic fuels (e.g., wood) is derived from solar energy. Difficulties with these fuels have led to the invention of devices that directly convert solar energy into usable forms of energy, such as electricity. Solar batteries, which operate on the principle that light falling on photosensitive substances causes a flow of electricity, play an important part in space satellites and, as they become more efficient, are finding increasing use on the earth (see solar cell). Thermoelectric generators convert the heat generated by solar energy directly into electricity (see thermoelectricity). Several projects have produced electricity on a large scale by using the solar energy available in desert areas. In one system, large numbers of solar batteries generate electricity for Coconut Island, off the coast of Australia. In another, oil flows through pipes that are set in reflecting parabolic troughs that can trap the heat from sunlight falling on them. The heat from the oil is then converted into electricity (see power, electric). Heat from the sun is used in air-drying a variety of materials and in producing salt by the evaporation of seawater. Solar heating systems can supply heat and hot water for domestic use; heat collected in special plates on the roof of a house is stored in rocks or water held in a large container. Such systems, however, usually require a conventional heater to supplement them. Solar stoves, which focus the sun's heat directly, are employed in regions where there is much perennial sunlight.

Also there are tons of info on this on the web just go to Yahoo search or Google and type in Solar Energy. It's not that hard.

Freddie Said:

From either temperature or solar energy, which is more important to the survival of a green leaf?

We Answered:

A plant will grow in a warm temperature but the leaves will not take to it's natural colour so it's more important for plants to have solar energy.

Ricky Said:

What's the importance behind using "these forms of energy"? Five Stars!?

We Answered:

The importance of using energy resources such as those is decreasing our reliance on fossil fuels, like oil or coal. Our supply of oil is running out, as it takes thousands of years to form in the earth, and these sources aren't going to run dry like oil is. Another reason is pollution. Oil and coal are causing a great deal of pollution in our environment, where these would not.
