Norwegian hydropower stations could be linked to wind farms and serve as giant “batteries” to even out power supply fluctuations, a Scandinavian research organization says. A major hurdle for renewable energy suppliers is intermittent power production …


According to the American Wind Energy Association, the last quarter of 2012 brought the total wind installations for 2012 to 13,131 megawatts of power. This influx of new power extends the total of cumulative wind capacity for the United States Read more…


The U.S. defense and aerospace giant, Lockheed Martin, is partnering with a major Chinese company to build a pilot project off the southern Chinese coast that will use temperature differentials between the deep and shallow ocean to generate electricity. The Read more…


UK officials are underestimating the vast energy potential of marine tides, a renewable and reliable energy source that could meet 20 percent of the nation’s electricity needs, according to a new report. Writing in the journal Philosophical Transactions of the Read more…


The earth contains enough wind energy to meet all of humanity’s power needs if future technologies are able to tap into high-altitude winds, a new study says. Using models to quantify wind energy potential, researchers at the Carnegie Institution for Read more…


I heard a really good talk about lifecycle analysis (LCA) yesterday that took wind energy as an example, and examined the overall ecological footprint associated with an individual large turbine. On average, about 7.8 megawatt-hours of energy goes into extracting Read more…


The operators of large California wind farms are considering the use of advanced radar and telemetry systems to reduce the number of birds killed by spinning turbines located in critical migration pathways. The so-called avian radar systems, which have been Read more…


Alstom and SSE Renewables have signed a new joint venture agreement to co-develop the world’s largest wave farm in the Costa Head Wave Project, off the coast of Orkney, Scotland. The farm will deliver up to 200 Megawatts of renewable Read more…


I attended the American Wind Energy Association’s 2011 Conference & Expo in Anaheim last week where I was able to see a lot of technology for turbines both large and small. On the small side, at 3.5 and 7.5 kW, Read more…


A U.S. startup says it has developed an enhanced geothermal energy system (EGS) that engineers say can tap into heat from the Earth’s interior without any associated risks of triggering earthquakes or polluting underground aquifers. While typical EGS processes require Read more…


It may seem like wind farms are a relatively new form of green technology, but they have actually been around for years—decades, even. In fact, the UK’s first commercial wind farm, located at Delabole in Cornwall, celebrated its 20-year anniversary Read more…


A wind turbine is a device that converts kinetic energy from the wind into mechanical energy. If the mechanical energy is used to produce electricity, the device may be called a wind generator or wind charger. If the mechanical energy Read more…


The South Korean government will help fund construction of a massive offshore wind farm that proponents say would generate about 2,500 megawatts of electricity and give the Asian nation a foothold in the emerging renewable energy industry. The 9.2 tril…


British designers are developing a new type of offshore wind turbine

that rotates on its axis, mimicking the spiral of a sycamore seed, and that stretches nearly 900 feet (275 meters) from tip to tip. The so-called Aerogenerator has two enormous arms …
