In Focus: GE’s Space Frame Tower

Greentech Media got an early look at GE’s new space frame wind turbine tower in advance of its official debut at next week’s European wind industry conference. The space frame advances the potential of GE to deliver taller towers capable of more power production at a lower cost. The GE Tehachapi facility’s enclosed-lattice, five-legged space frame prototype is 97 […] Read more


California Green Bank are Coming

Two weeks ago, State Senator Kevin de León introduced a bill to establish the first “Green Bank” in California, a bold proposal that would unleash low-cost financing opportunities for clean energy projects throughout the Golden State. I recently had the opportunity to testify at a hearing on the bill to discuss the best practices for green banks […] Read more


Chicago’s New LEED-Platinum Factory

Chicago will soon be the site for one of the few LEED-Platinum factories in the US, where environmental cleaning products from soaps to laundry detergent will be produced. Method, now a subsidiary of green cleaning product pioneer, Ecover, hired William McDonough + Partners to design the factory. The state-of-the-art facility is going up in Chicago’s historic Pullman district, where Pullman railroad cars were built. The 175-acre […] Read more


The Rise of Solar

There’s a great scene in the classic comedy “The Jerk,” where Navin Johnson, played by Steve Martin, jumps for joy when the new phone books arrive. Screaming, “The new phone books are here! The new phone books are here!” Navin acts similarly to the way I act when the annual U.S. Solar Market Insight Report […] Read more


Electric Utilities: Adapt or Die

Two seemingly unrelated announcements drew much attention in the electric utility industry recently. First, the Edison Electric Institute (EEI) (the trade group for the U.S. electric utility industry) and the National Resources Defense Council (NRDC) jointly recommended changing how utilities should be regulated. Second, Duke Energy announced it will sell 13 Midwest merchant power plants. These announcements are actually […] Read more


The U.S Military LOVES Solar Power

If ever there was a champion of efficiency, the military would be it. Energy efficiency is no exception to this generalization. As The Solar Foundation (TSF) and Operation Free tell us in a recent Veterans in Solar report, the U.S. military has scaled up its use of distributed renewable energy technologies, at home and in combat […] Read more


Transparent Colorful Solar Cells Have Arrived!

Transparent, colorful solar cells invented at the University of Michigan could one day be used to make stained-glass windows, decorations and even shades that turn the sun’s energy into electricity. The cells, believed to be the first semi-transparent, colored photovoltaics, have the potential to vastly broaden the use of the energy source, says Jay Guo, […] Read more


In Focus: Eco-Friendly Toys

When it comes to toys, most parents are aware of how important it is to select age-appropriate products for their little ones. However, there are other issues with toys that go beyond whether they are a choking hazard or not. Most toys, for example, are not made with the environment in mind; in fact, some […] Read more


Carbon Capture From Natural Gas in the UK

The first industrial carbon capture and sequestration (CCS) project from natural gas has been given the go-ahead by the British government with Shell as the contractor. Shell UK is launching the design phase for Peterhead Carbon Capture and Storage in Aberdeenshire, Scotland. It would capture over 85% of CO2 emissions that would otherwise be released into the atmosphere and then transport it through an existing pipeline […] Read more


Solar FIT Live in Los Angeles

When it comes to rolling out solar across the rooftops, Los Angeles is the city to watch. With 100 MW of installed solar capacity to distribute among building owners who can sell back the energy to the grid, the city’s Department of Water and Power is currently implementing the largest solar feed-in tariff program in […] Read more


Smart Choices for the Smart Grid

These days it’s about more than just being smart; it’s about creating a world that we would be proud to leave for future generations. As the conversation for smart grids continue to grow, we need to realize that more must be done. Smart grid technologies are a step in the right direction for environmental, financial, […] Read more


Solar: Helping Pot Growers

The sun’s been around for a long time. So has marijuana. Legal pot in the U.S. hasn’t been around for a long time. In fact, earlier this year Colorado became the first state to sell legal marijuana in the U.S. With the county’s—if not the world’s—eyes on Colorado’s new policy, growers are looking for opportunities […] Read more


The Perovskite Moment

The Silicon Solar PV industry has achieved miraculous cost reductions moving the cost per watt of PV down 100X in 35 years, for which they have been rewarded with a enormous growth in the industry and consumer base.  Solar PV has moved from a niche (serving calculators, watches, spacecraft, remote equipment) to being main stream […] Read more


Superabsorbing Design = Cheaper Thin Film Solar Cells?

Researchers from North Carolina State University have developed a “superabsorbing” design that may significantly improve the light absorption efficiency of thin film solar cells and drive down manufacturing costs. The superabsorbing design could decrease the thickness of the semiconductor materials used in thin film solar cells by more than one order of magnitude without compromising the capability […] Read more
