My question is, how come there was widespread drought and heatwaves before the industrial revoloution?
One of the big problems with solar is...
Solar Panel -> Battery -> House
... and those batteries usually have a high cost, full of chemicals and don't last that long in scheme of things (usually 10 years).
I have a friend who is working a coal power station (clicky) at the moment, it was built in the 1980s and puts out as much polution as a few hundred cars a year. The removed soil and left over carbon is also thoroughly processed before being put back. And anyone who complains that the big hole they dig is a twit. The hole is nothing compared to the size of the Earth. My bet is, the amount of people who complain take up more surface area than the hole itself. I'll be supporting coal for as long as my country has lots of it. I'm not giving up my two strokes any time soon either.
Perhaps the real issue is the amount of cars, how often do you see a massive 5 seater car with 1 person in it? 90% of the cars usually :)
