What source of renewable enery for human needs could supply four-fifths of the U.S, requirements in the immeda

Question

A. Coal
B. Wind farms
C. Solar Cells
D. Nuclear power

Answer 1

Well Coal and Nuclear aren't renewable, and Solar cells are still fairly inefficient and expensive.

I would say B - Wind farms.

Answer 2

E. None of the above

As already pointed out, coal and nuclear energy are not renewable. Solar cells are still far too ineffective. Wind farms, while great, are limited to very select regions of the country and could not support 4/5th of the supply for energy.

So....we still need something else that would work. Sorry...

Answer 3

Geothermal--the Earth is a molten lava ball with a thin crust of solids--tap into that forever.

Answer 4

none of the above. there is an energy source that would supply all the energy needs forever. it is converting energy from the heat of the oceans. renewable, inexhaustible, cheap (or will be soon. technology exists now).
