Sweden launches world's first quick-charging electric passenger ferry
The simplicity of the electric drive system is expected to lower running costs by as much as 30 percent when compared with a typical marine diesel ferry. They will be quieter and cleaner, and vastly more energy efficient than the diesels, which put out some 130 tons of carbon dioxide, 1.5 tons of nitrous oxide and burn around 50,000 liters of diesel per year.

Small-Scale Wind Power - Renewable Energy - MOTHER EARTH NEWS
Small-Scale Wind Power - Renewable Energy - MOTHER EARTH NEWS
Wind energy blows hot and cold based on local energy pricing, available tax incentives, market production, transportation costs, and so on, but generally, it has been a fast-growing renewable energy sector. Since the 1980s, the cost per kilowatt-hour of wind has dropped 80 percent; it is approximately 2¢ cheaper per kWh than coal-powered electricity on the U.S. market as of June 2012. And that’s without accounting for the cost it saves our system due to decreased carbon dioxide emissions. About 24 percent of Denmark’s energy needs reportedly are met by wind, and the country has plans to grow that to 50 percent by 2020. Serious wind development is happening
