We must continue research into new forms of energy and into more efficient use of existing energy sources.

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

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

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

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

Whether it is to reduce our carbon-dioxide emissions or to prepare for when the coal and oil run out, we have to continue to seek out new energy sources.
