That's generally how I think as well. When they say: it was the hottest summer in 100 years, I only think, what is a 100 years?
I doubt we're the only ones affecting the climate of our planet, though we might be making a contribution. I read a piece about how lessened vulcanism and increased solar activity also have a major say in the heating up of the planet.

Things like wind farms and tidal generators are fine for producing electricity, but electricity is only one energy form in use. In the US, electrical power was about 1/4 of the total energy budget the last I knew. Industrial, commercial and residential heating and cooling and transportation accounted for the majority. Burning coal, oil, and natural gas accounted for the majority of that.

Biomass being made into gas (by fermentation) is a good replacement for natural gas as well as fueling gas plants. And I think most oil based engines will be replaced with electric engines within my life-time.
