We need to develop clean, affordable, and reliable energy sources, and frankly, we need to license that technology to the rest of the world.

There's an overemphasis on conservation and other idyllic energy sources that can be harmful in that it hampers new technology and innovation.

We should not just consume hydrocarbon fuel but use it to develop nuclear energy, hydro power and renewable energy sources.

With the right infrastructure in place, home solar will be recognized publicly as affordable, easy, and smart, and every new home built in the developed world can have clean energy sources built into it.

Of course we have to use coal... the renewable energy sources will supplement the supply from coal.

I spent more than 20 years of my professional career researching and developing renewable energy sources.
