The bicycle has many attractions as a form of personal transportation. It alleviates congestion, lowers air pollution, reduces obesity, increases physical fitness, does not emit climate-disrupting carbon dioxide, and is priced within the reach of the billions of people who cannot afford a car. Bicycles increase mobility while reducing congestion and the area of land paved over. Six bicycles can typically fit into the road space used by one car. For parking, the advantage is even greater, with 20 bicycles occupying the space required to park a car.

Greening The Grid

Submitted by glenshewchuck on
Show

Utilities and environmental groups are coming together to help modernize the transmission system. It's an arduous job that requires conciliation and patience. Together, they seek to improve the grid's capabilities to allow it to carry more green electrons as well as provide customers with the information they need to make better energy choices. With Congress now considering national renewable energy mandates and at least half the states with such laws on their books, electric companies must have a way to deliver the expected use of those renewables.
