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

Los Angeles Says No to Fracking

On Friday, the Los Angeles City Council voted unanimously for a moratorium on fracking.  Now it goes to the city’s attorney for zoning changes and then back to the city council for a final vote. That followed news from Texas that Exxon’s CEO joined a lawsuit to block fracking equipment near his house, and Denton,  a city in the cross-hairs of fracking - got a referendum on […] Read more

UNVEILED: The U.S Renewable Energy Roadmap

Stanford University scientist Mark Jacobson has developed a 50-state renewable energy roadmap for transforming the United States from dependence on fossil fuels to 100 percent renewable energy by 2050. He unveiled the plan at the annual meeting of the American Association for the Advancement of Science in Chicago. “Drastic problems require drastic and immediate solutions,” said Jacobson, […] Read more

Apple Claims Green is Still A Priority

One thinks of Apple CEO Tim Cook as being an extremely calm person, but he drew a hard line against a conservative faction of shareholders who complained that the company should focus entirely on its bottom line, and knock off its demand for renewable energy and its participation in other sustainability initiatives aimed at stemming climate […] Read more

Making the Data Center Greener

It takes a lot of energy to make your data center operate at optimal performance. That surge of electricity not only causes high bills but also leads to increased emissions that affect the environment. Large data centers use more than 30 billion kilowatt hours of electrical power in a year, and some use enough electrical […] Read more

New Spy Technology to Spawn Oil Revolution

The future of oil exploration lies in new technology–from massive data-processing supercomputers to 4D seismic to early-phase airborne spy technology that can pinpoint prospective reservoirs. Oil and gas is getting bigger, deeper, faster and more efficient, with new technology chipping away at “peak oil” concerns. Hydraulic fracturing has caught mainstream attention, other high-tech developments in […] Read more

Gulf Of Mexico: Dirty Energy Exploitation Now Allowed

Tue, 2014-02-25 05:00Farron Cousins It has been nearly four years since BP’s Deepwater Horizon oil rig explosion and oil disaster in the Gulf of Mexico, and neither the dirty energy industry nor politicians in Washington, D.C. have learned anything…

Solar Thermal Farms: Popularity Fading?

392 megawatts, 173,000 heliostats, 347,000 mirrors, $2.2 billion investment and a $1.6 billion federal loan. These are the tremendous numbers surrounding the development and construction of the Ivanpah solar thermal power facility in the Mojave Desert, 40 miles south of Las Vegas. Such a plant, who can energizes up to 140,000 houses, is a massive solar energy […] Read more

CdTe Solar Cell Efficiency Record Announced by First Solar

First Solar, Inc. announced it has set a world record for cadmium-telluride (CdTe) photovoltaic (PV) solar cell conversion efficiency, achieving 20.4 percent conversion efficiency certified at the Newport Corporation’s Technology and Applications Center (TAC) PV Lab and confirmed by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). The record-setting cell was constructed at […] Read more

New York Lands $1 Billion for Solar

In his January State of the State address, New York Governor Andrew Cuomo announced an even greater commitment to clean energy during the next ten years. Cuomo’s NY-Sun Initiative has already seen great success, and Cuomo is looking to build on that success to put New York at the top of the U.S. solar rankings. Here are the highlights […] Read more

In Focus: High Efficiency Solar PV Module Manufacturers

When we design a solar installation for a Massachusetts home, available roof space generally is the limiting factor.  High efficiency equipment should be considered to pack the most power in the least square footage.  High efficiency isn’t the only thing that matters, though.  An installer should also look at the manufacturers’ financial health, longevity, and warranty, […] Read more

Solar + Batteries = End of Utilities?

Rooftop solar panels combined with battery storage have very real potential to destroy the reigning grid utility model, according to a study released this week by the Rocky Mountain Institute. And the destruction could happen quickly. “We weren’t really surprised to see that it could happen,” said Jon Creyts, RMI managing director. “What surprised us […] Read more
