The bulk of discussion of wind turbines centers on blade design, turbine efficiency, and above all, siting constraints. Engineering that reduces objectionable low-frequency wind noise is making great strides, notably the Skystream and Swift designs, offer great incentive for community-…

Locally Generated Wind And Solar Power
In the past, I’ve been bothered by plans being developed in shoreline communities, particularly here in Massachusetts, for wind systems in the Berkshires 100 miles inland. It has seemed odd that these towns wouldn’t want to generate wind-based power nearer…
Solar Cell Advance Promises 97% Efficiency
Researchers at Rensselaer Polytechnic Institute have developed a new solar cell structure that cuts cell reflectivity to 3 percent, down from 33 percent in more traditional solar cells. This advance puts solar energy on a very good footing vis-a-vis fossil fuels, with their roller coaster price and huge ecological disadvantage.
