Renewable Energy Universe

admin answers:

Talk about all 3 in your intro then in your body paragraphs talk about about each one separately. Some other ideas: cars running on water, Solar Panels, wind power

hope i helped

admin answers:

It all comes from the sun, directly or indirectly and it varies with where you are. If you are in the NE USA, around the fall line, water power is feasible. If you happen to be around Mecca, in Saudi Arabia, solar panels would be ideal. That area gets the most insolation on Earth. Not a good spot for river power, though. Tidal power works well if you are along the ocean and nearer the poless than the equator, as in the Bay of Fundy. Wind power is dependable on the Great Plains and id dependent on local topography to a large extent.

admin answers:

solar power, and wind generators, along with power stations at large dam areas using gravity from water.

Fossil fuels have been relatively cheap for the last two hundred years. Only recently has the true cost been appreciated. Until the greenhouse gas problem was discovered, nobody assumed that there was any cost to dumping carbon dioxide into the air. That is, the fossil fuel users have assumed that the disposal of the exhaust gases was free.

The other point is that a lot of the renewable sources of energy require high technology, e.g., hydroelectric dams, advanced windmills and solar electric generating systems.
