Government should give tax breaks for companies who use renewable energy. That might encourage them to actually use renewables as well as stimulate the renewables sector since there would be increased demand.

There has been several proposed projects in the past but I would like that at least someone focus on extracting energy from waste. Methane is a potent greenhouse gas and the less we pump out, the better. I don't know much about chemistry but I read that when burning methane, the byproducts would be just water and carbon dioxide. Sure, CO₂ is still a greenhouse gas and it's one that we're producing the most but it's still less potent than methane.

I remember Kaoshiung in Taiwan has converted an old dump site into a power plant (more reasons to segregate trash). Here in my 3rd world country, there are hog farms that collect the waste into a covered tank to produce methane, which they burn for electricity as well as for cooking.
