It's about time that big power companies stopped messing around with green energy and took it seriously. Kudos to Southern California Edison for ramping up to 250 megawatts of solar power on the rooves of commercial premises (reports Green Wombat).
Solar power in itself won't supply the earth's energy needs by a huge margin (quite apart from the green impact of making the solar cells/kit in the first place), but it's a good start. Add in more and more wind turbines and wave power generators and I can see some countries getting a quarter or even a half of their power from green sources by about 2020.
Save the planet? Maybe we just will. But we need more initiatives like this one.
