New Solar-cell Design Based On Dots and Wires

Using exotic particles called quantum dots as the basis for a photovoltaic cell is not a new idea, but attempts to make such devices have not yet achieved sufficiently high efficiency in converting sunlight to power. A new wrinkle added by a team of researchers at MIT — embedding the quantum dots within a forest of nanowires — promises to provide a significant boost.

Current Builds Behind Tidal Energy Take-off

Romania To Scale Back Subsidies

Romania, which Ernst & Young called “Eastern Europe’s renewables haven” just a few months ago, now plans to follow other nations’ recent moves in scaling back renewable energy subsidies to avoid further consumer price increases, the nation’s minister-delegate for energy, Constantin Nita, announced in early March. The country is planning to cut the maximum value of its green certificates this summer or early in 2014, Nita said.

The Clouds are Getting Greener: Apple Data Centers Powered by 100% Renewables

Just one year after Greenpeace called out Apple for its use of fossil fuels in its “How Green Is Your Cloud” report – which graded Apple no higher than a “D” in four categories consisting of energy transparency, infrastructure siting, energy efficiency, and renewables and advocacy – Apple announced that its data centers are now powered by 100 percent renewable energy. In fact, renewables contribute to 75 percent of its entire corporate operations energy needs, according to its website.
