A step in the right direction. The solution is always going to be a mix of technologies. One size does not fit all
A couple of weeks ago I flew over Altamont Pass just east of San Francisco and the wind farms weren't doing much...but it was sunny, so solar facilities would be cranking out the watts. As it should be. Earlier in the summer I was in northern Alberta (Edmonton -> Peace River -> High Level) and the perpetual wind had me watching for wind turbines. Saw a few.
Here in B.C. we have lots of hydroelectric capacity (and some fossil fuel generation, alas...) and are playing with wind and tidal power. Our climate isn't particularly sunny (except for the Okanagan), so solar is a non-starter.
