The sophisticated engineering, delicate structure and graceful flight of solar-powered aircraft is a beautiful vision in efficiency. A formation of fighter jets makes the very skies thunder and the ground shake, exciting in its power. This dichotomy is everywhere, especially machine racing sports.
So where can environmentalists and energy efficiency enthusiasts get the excitement of power without the indulgence of excessive wastefulness? And where can people who love seeing jaw-dropping power get fired up by green technology without having to develop an appreciation for boring economy?

Why are solar panels for the home so expensive? What makes them out of reach for most consumers-the technology, the difficulty of installation, or the parts needed to build them? What would be the key to making them as cheap as buying a microwave for example?

I am working towards developing an energy education for local schools in Northern California. Does anybody have any helpful resources or places I should look?
Unfortunately, I don't have anything to narrow the search as this could encompass anything from k-12. Resources can include curriculum, print outs, science kits (within a reasonable budget), competitions, etc... Pretty much anything that would get kids interested in renewable energy and energy efficiency.
Any and all help would be appreciated!

Should I have our small business switch to a third party green energy provider? We had a salesman for
Accent Energy come to our door and he was a bit shady so I told him that I wanted to look into this on my own time. But from what I'm reading online it could be a great way to convert to a more environmentally responsible energy solution. And its Earth Day today too. Our company wants to do what we can to be "green" and we would even pay slightly more to do so, but if a switch to a third party will cost three times as much then we just cant do it.

In a recent interview on Sky TV, a Greenpeace campaigner cited a UK town (or district) effectively unplugging itself from the national grid power distribution system, using local power generation, and reducing its power consumption by 75% (if I recall). Do you know where he was talking about?

Why do so many clothing stores in southern California leave their doors open with the AC on and blasting into the scorching heat outside, even though we're in the middle of an energy crisis? I'm referring specifically to a Banana Republic store in an outdoor shopping district in Pasadena, California, but I've also seen this in other SoCal areas as well. Is this some marketing gimmick meant to entice customers away from the heat? Or do some employees really don't know any better?
