New York City, New York.
Los Angeles, California.
It increases plant growth.
Warmth is needed for it to occur.
It is a natural phenomenon.
Heat is trapped.
Can utilize even low wind speeds to produce electricity.
Uses one vane.
Does not have to store electricity.
Is not expensive to build.
Food from plants and animals
Irrigation is needed to reclaim the land.
It removes good topsoil from productive use.
It creates erosional problems.
All of the above.
Nuclear fusion power plants are being built instead.
Federal laws were passed prohibiting the development of new nuclear power plants.
Nuclear power plants have become too expensive to generate electricity at a reasonable cost.
Supplies of 235U are exhausted.
The United States has large coal reserves.
Processes for gasifying coal are well established and little research is necessary to make gasification a reality.
Gasified coal can be made into a gas that can be used in the gas furnaces we presently have in our homes.
Coal can be gasified into a low BTU gas for burning at electrical power generation plants.

The water is crystal clear.
Produces nearly all the fresh water in desert countries such as Saudi Arabia.
Can be accomplished by distillation, using heat to evaporate pure water, leaving salts behind.
Can be accomplished by pushing water molecules through a membrane with tiny holes that salt molecules cannot pass through.
Can be accomplished by using innocuous chemicals to precipitate salts out of the water.
Burning of fossil fuels
Radon and ozone
All of these contribute about equally to acid precipitation
