At the risk of boring you again, I'll play who said this one more time and call it quits for the week.   Who said the following:

"there is no proof global warming is caused by humans"

"There isn't enough potential for wind, solar, hydroelectric, and geothermal or other renewable energy sources"

"the only alternative to nuclear power for producing continuous energy at the levels needed is natural gas"

The answer is Dr. Patrick Moore, founder of Greenpeace.
