I support renewable energy.

The future is green energy, sustainability, renewable energy.

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

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.

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

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