Take the Alternative Energy Challenge

Prove me wrong on the following assertions:

There is no electrical power grid, owned by a public utility, any where on the face of the earth, that is powered exclusively by wind power, solar power, or a combination of the two.

There has never been a fossil fuel electrical generating plant on the face of the Earth that has been replaced by wind power, solar power, or a combination of the two.

There has never been a nuclear power plant on the face of the earth that has been replaced by solar power, wind power, or a combination of the two.

In order to meet present electrical power demand, for every megaWatt of wind or solar power capacity that you have, you must also have a megaWatt of fossil fuel, nuclear or hydropower.

There is no solar cell factory on the face of the earth that get its power to operate exclusively from solar cells.

There is no wind turbine factory on the face of the earth that gets its power exclusively from wind energy.

Without diesel fuel, a wind farm ceases to operate.

If you have evidence to prove any of these assertions wrong, please post that evidence in a comment.
