Renewable energy is not more expensive than fossil fuel when you factor in life-cycle costs.

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

I support renewable energy.

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.

The future is green energy, sustainability, renewable energy.
