A co-worker told me that solar panels won't work that well in Canada because the sun's rays doesn't hit us as directly as somewhere closer to the equator. So an equivalent solar panel setup in somewhere like Texas will create a lot more energy then one in Calgary.
A little off topic, but I read on slashdot a while ago that some researchers are working on a device that you can wear that captures energy from your body. So maybe someday in the future you can keep your iPod charged just by walking to and from the bus stop! I thought that was pretty cool.
