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 to 60,007 megawatts. However, some states are much (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 technology, known as ocean thermal energy (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 Royal Society A, researchers explain that while the process of exploiting tidal energy remains (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.
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 the materials, forging the pieces, transporting, assembling (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.
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 energy utilizing AWS Ocean Energy Ltd’s (AWS) Archimedes Wave Swing III technology (AWS-III). (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.
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 developers to (more…)
