Using batteries to retain energy from rooftop solar systems will be too expensive for at least two years, according to industry executives.
Wuxi Suntech Power Co., the solar manufacturer acquired earlier this year by Shunfeng Photovoltaic International Ltd., plans to ship almost twice as many modules this year, in the latest sign of a rebound.
The price of an average U.S. home solar power system is about $20,000. (That’s before a 30 percent federal tax credit and any state, local and/or utility incentives.) If the price were to drop to $17,000, or even $16,000, would you be buying?
Sandia National Laboratories has begun lab-based characterization of TransPower’s GridSaver, the largest grid energy storage system analyzed at Sandia’s Energy Storage Test Pad in Albuquerque, N.M.
Six years in the making, state and federal agencies released five options with a “Preferred Alternative” draft for the Desert Renewable Energy and Conservation Plan (DRECP), potentially kneecapping development in the best solar region in the U.S. by cutting off previous access to public lands and reducing eligible acreage by two thirds.
One third of all energy is wasted. Is PACE the solution? According to current energy data, commercial and industrial buildings use about 60 percent of the energy generated in the U.S. and about a third of this energy, especially in older buildings, is wasted due to inefficiency. But how do we know which third, and what can we do about it? The answe
A wind turbine’s main shaft requires a reliable bearing for operation. Some bearing designs have been known to fail prematurely resulting in costly maintenance repairs. Recent upgrades and advances in bearing designs increase reliability, and ensure main shaft stability. Selecting the proper bearing is beneficial to a wind turbine’s overall performance.
The last day of Solar Power International tends to be a little more casual. Exhibitors, exhausted from frenzied activity over the first two days, can take a step back and reflect a bit. Check out our slideshow for more scenes from the tradeshow floor.
Adaptability is the key to survival — both in nature as Charles Darwin observed, and in the business sector. As the solar industry continues to flourish, utility companies across the U.S. are beginning to witness how the traditional electric grid is transforming. As tens of thousands of residents have solar photovoltaic (PV) panels installed on the
The green revolution and, in particular, renewable energy products such as solar power, wind turbines, geothermal and algae-based fuels are not waiting for viable technology — it already exists in many forms. What they are waiting for is a massive sea change in our antiquated financial accounting systems.
It was great to see economists in two separate New York Times opinion pieces recently noting that controlling climate pollution may be economically beneficial rather than restraining growth, as conventional wisdom among economists has held.
With more than 20,000 panels, the largest rooftop solar array in the U.S. (second largest in the world behind a 7.52-MW installation in Punjab, India) is about to be commissioned on top of the Mandalay Bay Convention center in Las Vegas, Nevada. A 6.4-MW solar array, which uses SMA inverters and Kyocera panels, covers the 20 acres of roofs on the convention center and its neighboring buildings.
The industry is abuzz at Solar Power International 2014 in Las Vegas, Nevada. Renewable Energy World is here to give you inside updates from day two on the show floor.
Imagine a place where there is no electricity market. No rules, no policies, no market. A clean slate. This is what the Solar Energy Power Association (SEPA) calls the 51st State, a new initiative to get people to think outside the box when it comes to utility design and infrastructure.
“It was the best of times, it was the worst of times,” so Charles Dickens wrote, and the same might be said for Enphase and RECOM, two solar exhibitors that were across the aisle from each other at this year’s Solar Power International. I passed their booths several times, and every time I did, Enphase had almost wall-to-wall traffic, while RECOM’s
After the D.C. Circuit Court’s invalidation of FERC Order 745, how can we pay for demand response? “Demand response” happens when electricity customers change consumption patterns in response to the needs of the power grid. Electricity customers can provide a substantial amount of demand response to grid operators without a noticeable effect on the
Last month, NRDC engaged a nationally recognized opinion research firm to conduct polling in New York State to evaluate public attitudes about fracking and clean energy. Importantly, this is the first statewide poll in at least two years — and perhaps ever — to directly ask residents their views of the now six-year-old de facto moratorium on fracking.
“Environmentally friendly,” “green,” “sustainable” — these words have become ubiquitous, plastered on products from handbags to home décor and everything in between. As a society, we’re more aware than ever of the difference we can make purchasing smart, sustainable products and the role we can play shifting to cleaner, green solutions like renewab
