He claims that by 2030 solar energy will meet all our energy needs.

He is clueless.

He is probably right about the biology thing, but you are absolutely right about the solar energy. He has no concept of the physics of how much energy is required to run the world. None whatsoever. His statement is just so much wishful thinking, apparently to make him sound like a good guy.

The counterargument made by solar advocates is that less power will be needed in the future because it will be more efficiently managed - that enormous amounts of energy are inefficiently expended today.

There are irreducible limits however, and environmentalists are already getting upset about large, ecologically disruptive panel arrays.
