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

I have been working for years to promote a responsible energy policy that works to increase energy efficiency and invest in alternative and renewable energy sources.

We've offered direct financial support for a range of renewable energy sources, whether it be large-scale solar, whether it be geothermal, whether it be wave power or wind power.

What my voting record reflects is constantly looking to improve the amount of resources we having going into research, development, and prototypes we have going into renewable energy sources.
