Everybody wants to have a cleaner Earth, but few of them take any actions. One of those people is Doug Selsam, who designed high-power wind turbines that can generate enough energy to power a home. The wind turbines measure about 14-18 inches in diameter and they can generate an impressive amount of 200 watts for a 20 mph wind, but the wind turbines could do better if the winds are stronger.

Residential wind turbines costing $500 to $700 have come of age, beating other renewable energy competition for the home market on price and efficiency.

I like this lens. It makes good sense to have a good basic understanding of whatever market you're trading but additionally if you don't have the right tools, i.e. resource evaluation indicators, and more you are ...in the wind, so to speak.

Dale Vince discusses whether demand generation is as effective as actual generation in terms of changing the way electricity is created and distributed.

Whats the biggest attraction you have ever seen? Mine would have to be the world’s largest nickel in Sudbury. Those roadside attractions that claim to be the world’s biggest always give me a bit of a chuckle, like the worlds largest ball of twine. All these attractions are funny but what about the worlds largest solar farm? Thats right, green/eco tourism is coming!

Ever wonder how many Huggers it takes to change a light bulb? No? Well, ever wonder the real cost difference between incandescent, CFL, and LED light bulbs? Here's a wiki article that looks at the cost of ownership of these different light bulbs that takes into account the initial cost of the bulb, its energy consumption, its light output, its lifetime length, and the cost of electricity.

Many entrepreneurs, activists, and marketers are leveraging the social web for positive change. In the process and by its very nature, they are giving each of us the tools to change the world and make it a better place.
