Like geo-thermal energy,solar power

K Im doing a survey to see what the most efficient energy alternative is. The choices for the survery are water power, wind power, geothermal power, nuclear power, biomass power, or solar power.
*Note if you can, give reasons why this is the best one

A. The wind and sun are not constant, so there would be times when no electricity would be generated.
B. The wind and sun are constant, so there would be plenty of electricity for the home.
C. Wind and solar power are inefficient and too expensive to use and maintain.
D. Wind and solar power are efficient, but they are not able to produce enough electricity for a single home.

Hello,

I was wondering if one day I wanted to buy good products for generating energy from alternative resources like the Wind power and the Solar power, which companies are the best in supplying those kinds of generators?

I'm not just thinking of small generators for homes, I'm thinking of a bigger level too. Like for big industrial companies or even National level!

Thanks a lot for your expertise exchange :)

Would this be extra helpful in locating platforms out of sight of people in order to preserve the natural coastal horizan from shore? Wouldn't this be easy to expand in locations where it was already built in order to keep up with increases in electrical demand without increasing carbon emissions? Could any country build this as long as it had coastline? Could this be sent to areas with natural disastors or predicted energy shortages as a way to help keep the power running? Could platforms also desalinate water and produce hydrogen on site? Could Solar Power also be located on it?

why are the environmentalist blocking wind power? in some parts of the usa. You would think they would want wind power everywhere. They say wind power kill birds. those blades move to slow to kill a birds i think. There also blocking solar power in the desert. why?
