All the clean, alternative energy resources are valid in my opinion. However, one of the best way to get environment friendly energy nowadays is a magnetic generator that, taking advantage of the nature's magnet forces, produces free electricty to power our homes. Greetings!
Alternative energy is nice, but I honestly don't think we'll ever see it become mainstream. Why do I say this? There's simply too much money in fossil fuels. We won't ever run out of oil, but it will become scarcer in the future and as a result more expensive to extract. You'll see the price of oil go up to levels that only the rich can afford, and everyone else will just have to cut back on consumption. I wish this wasn't the case, as we are obviously doing enormous harm to the planet if we continue along the current path, but something tells me it won't change anytime soon.
