Hydropower “Battery” Could Even Out Wind Energy Supply

written by Yale Environment 360

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 — sometimes too much

Which States are Getting Wind Energy Right?

written by Walter Wang

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

Tidal Energy Can Meet 20 Percent Of UK Electricity Needs, Report Says

written by Yale Environment 360

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

Earth’s Wind Resources Could Meet Global Energy Demands

written by Yale Environment 360

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 Science and the Lawrence Livermore National Laboratory

Life-Cycle Analysis and Wind Power

written by Walter Wang

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

Wind Farms Consider Radar Systems to Prevent Bird Deaths

written by Yale Environment 360

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 deployed at wind farms in Texas and Europe, would

Windspot by Sonkyo and Synerdrive by Kenersys

written by Walter Wang

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, was Sonkyo Energy’s WINDSPOT turbine.

New Geothermal System Taps Heat Without Geological Risks, Firm Says

written by Yale Environment 360

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

UK’s First Wind Farm Reopens with Incredible Revamp

written by Solar Calfinder

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 with a multimillion-pound renovation. Delabole

Building a More Efficient Wind Farm

written by Environmental News Network

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 is used to drive machinery, such as for grinding grain or pumping water, the device

Game Changer: New Design for Offshore Wind Turbines

written by Yale Environment 360

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 that extend from the base of the structure in a V-formation, each
