Answers
I just have a few, please give me an answer not just a website or copy from a site(definitely not wikipedia)
-Can anyone explain what active and passive solar energy is
-Is it true that solar panels create pollution, if so how is it...
What a lot to read. Ignoring the essay
-Can anyone explain what active and passive solar energy is
Active is collecting the energy and moving it as hot liquid, air, steam, or electricity. Passive is having the sun shine in...

I bought a solar cell just recently. I went to hook up the leads to the ends of a hobby motor. However, to my dismay, I found that the motor was not running. Is the solar cell unpowerful? The specifications on the cell are 3 volts at 20...
More importantly what is the motor rated at? If your motor is supposed to be 12V and 1Amp, then you're not going anywhere. Also were you outside on a bright day? Were you inside under a very strong uv light? There are many reasons why this would...

So I have a couple solar cells off some outdoor yard lights that I replaced with new up to date lights so these were for parts. I know solar panels produce power during light but during no light conditions have the ability to suck power back out...
Any diode will do.
But the voltage out of the solar cells must be higher than the battery voltage by a bit before the battery will charge. For example, a 12 volt lead acid battery won't charge until the voltage gets above 14-15...

Please humor my idea for a moment. I had this idea for an eco-friendly car. Its basically the Ford Fusion only with solar panels covering the car with the fusion generator that is already currently built into it (instead of using gas as a...
Solar panels make energy so slowly that your idea won't work well. I believe you need to get into "the numbers" yourself. You don't need to be a licensed engineer. "Build your own Electric Vehicle", a book by Seth Leitman and...
According to the available data, France currently generates 70% + of its electricity using nuclear power. Yet here in the United States we haven't broken ground for a new nuclear generating station in decades. We're still using coal, oil and...
Here is why we can't: the people who support alternative energy are incredibly ignorant of the costs of producing such alternative energy, and believe in magical thinking--that you can get something for nothing.
For example, solar...

Possible US, China trade dispute looms
The U.S. government will decide whether China-made solar cells, high-pressure steel cylinders, galvanized steel wires and steel wheels from China are dumped, or sold below cost, in the U.S.
If so, it could impose tariffs that impair Chinese companies' ability to sell those products in the U.S. China's Ministry of Commerce, meanwhile, has launched its own investigation of American solar cell makers, and is also probing such U.S. industries as photographic paper. The agency could decide to impose duties as early as this year.
The U.S. rulings on China-made solar cells will be politically sensitive because of the dollars involved — the U.S. imported $1.5 billion worth of solar cells from China in 2010 — and the fierce competition between the two nations to develop renewable energy sources.

The “Almost” Forgotten Energy
Absoprtion of solar energy by atmospheric convection, evaporation and condensation of water vapor powers the worldwide water cycles and determines and drives wind streams. Solar energy converted into chemical energy via photosynthesis produces food, wood and the biomass from which fossil fuels are derived. Solar radiation and sunlight, with the addition of a variety of solar resources, accounts for 99.9% of the renewable energy on Earth! The available stores of solar energy accessible in the natural environment way beyond sufficient in comparison to current human energy needs.
Solar energy technologies and other technologies that use sunlight and secondary solar resources are critical to the current green/cleantech revolution.
