PV Gap

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 a realistic year for solar power to become a viable energy source?

We Answered:

Compared to our overall energy consumption, solar power is simply a weak energy source. IF we used much less energy, and wasted less, and had more efficient machinery, then it could be a much more significant energy source. But we're too used to cheap high-energy fuels (oil, gas) to make things as efficient as they should be.

You can set up your house for all-solar operation, but you have to make a lot of changes in how much energy you use, when you use it, and you have to make your home much more energy efficient, change your appliances, seal the doors, install insulated windows, you have to rethink and retool the whole house. We should be doing this already, but we're just too used to all that cheap fuel to bother with being efficient with it!
