One other comment about solar electricity. The cost, per kilowatt hour of solar electricity, based on a 30 year system lifespan, currently is .38. Compare that to oil, coal or gas generation at LESS THAN .05 per kilowatt hour. I really don't see any economy there at all. There are certainly applications and cases where solar power is either economical or required by other limitations, but in general, at almost eight times the cost, I don't think it's a very good choice. Incidentally, I got those numbers off a site that is pro-solar.
Konstantine, there was a movement going on here in the US not too long ago to make us stop eating beef to reduce the number of cattle and thereby reduce the amount of hydrogen sulfide from cow flatulence which is, supposedly, a major contributor to greenhouse gases and climate change. As Ripley once said, "Believe it or Not".
