Ecopole solar-wind powered street light claim

This provides a sort of "fail safe" mechanism that will give the light some way to charge even when it is cloudy out. SavWatt, the creator of the Ecopole solar-wind powered street light claim that this is a much more reliable alternative to the all solar street light.

While a street light that has no carbon footprint is not likely to seem like an altogether big deal in the scheme of going green, these little changes can make a big difference. Besides, just think about the number of street lights in your own community and think about what this adds up to as a nation. Switching this fleet of inefficient halide lights to lights powered by the sun, wind, or both, would make a big difference.
