Solar Power questions!?

Question by <(__)>: Solar Power questions!?
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 better used in space?
-When silicon or other semiconductors in solar cells absorb solar energy do the create electricity because the electrons “move” instead of shaking and producing heat?

Oh yeah just curious and I don’t really need an answer for this right now, but do u think this is a good introduction to an essay about solar power? I’m afraid it might be a little off topic (ignore the parentheses and numbers they’re sites from my bibli)
Thousands of years ago the Chinese began to use coal for a source of fuel.(7) Since then the needs and demands for coal and other fossil fuels have gradually increased, especially during the last few decades.(3) These fossil fuels are materials like petroleum, coal and natural gas that were formed millions of years ago from living matter. With the overuse of this nonrenewable material people have begun to wonder what will happen when it runs out, what sort of energy source will be used after all fossil fuels have been used up. In response to this growing problem people all over the world are racing to create a new source of energy to replace this ever diminishing supply of fossil fuels. As these fossil fuels are burned to create electricity though, gases are also released into the air. Carbon dioxide, Sulfur dioxide and Nitrogen oxide are all gases that are released when fossil fuels are burned. These gases are known to cause global warming and acid rain.(1)
Energy sources that can replace these fossil fuels are called alternative energies. With alternative energies or “Green Energies”, people will be able to have a cleaner and more sustainable energy source. Hydroelectric power which is produced from falling water, geothermal power that is produced from the heat inside the earth and wind power that is made from moving air or wind are all possible replacements. Another possibility is also available. By using power from something that is constantly facing the earth and giving off its power whether we harness it or not we can be provided with an unlimited amount of energy. A source of power that aside from the cost of the material needed to capture its power is free; this power source is the sun, a yellow dwarf star that is 93 million miles from the Earth. The electricity produced would be able to constantly power people’s homes, cars and other electronics. How can people do such a thing though? What do they need to convert this energy that has existed for over five billion years into electricity? During the research the researcher wished to understand the potential of solar power as an alternative energy. During this research the researcher will also explain how solar power works, the history of solar power and the benefits to using it as an alternative energy.
