If he did a bit more research instead of most likely reading from a script, he would find that there is a clean renewable energy that uses turbines and has the capability to be immensely powerful and power the world for thousands of years. Geothermal energy, along with solar, wind and the two ocean-based sources he didn't mention (tidal and wave energy) has the potential to wipe out the need for coal/gas/nuclear firing power stations forever.
