Renewable energy (solar, wind, water, hydro, tidal and wave, geothermal, ocean thermal, biomass and biofuel).
Here's a list of the major renewable energies:1. Solar2. Wind3. Hydro power4. Geo-thermal5. Bio fuels, such as ethanol and bio-diesel6. Tidal energy
If your going to copy and paste your homework questions for other people to do for you, why not try either doing what the question asks or removing the bit where it asks you to look in a book.
No, WikiAnswers will not do your homework for you. That's cheating. Make a list of all the positive things about renewable energy -- you're going to have to do some work and research this using your textbook! -- now pretend you're telling a friend all about these things and trying to convince them to use renewable energy. There's your letter.
Each state publishes a list of green companies doing business in that state. You can also get information from The Ultimate Green List and Green Renewable Energy Companies.
* Solar energy (direct or concentrated) * Wind energy * Hydroelectric energy (from rivers) * Wave energy * Tidal energy * Geothermal energy (from underground heat) * Biofuels (Although from an environmental point of view they can quite damaging)
There are several options for renewable energy sources. They are: wind power which uses air flow, solar energy which collects energy from the sun, geothermal energy and of course biofuel such as ethanol. A great resource for finding tons of information on this subject is wikipidia @ http://en.wikipedia.org/wiki/Renewable_energy
When it comes to the flow of energy in ecosystems there are two types of organisms: producers and consumers.

Geo-thermo energy is not renewable at all. We suck heat out of the earth it is gone. once we run out the core of the earth is cold. No volcanos. No earthquakes. Nothing to stop erosion from sucking all the land into the sea. Yet people list it as renewable, because we have such a huge reserve that they suspect our civilization will be destroyed by something else long before we run low.
