Renewable Energy

Having successfully negotiated the challenging regulatory slopes of the U.S. Bureau of Land Management, the U.S. Forest Service, the U.S. Department of Energy, and a host of Oregon state agencies, the Newberry Enhanced Geothermal Systems (EGS) demonstration project is in the process of creating a new geothermal reservoir in central Oregon. The core of the new reservoir is a two mile (3.2 km) deep well drilled about four miles (6.3 km) from the center of Newberry Volcano. The rock surrounding the wellbore reaches temperatures in the order of 600° F (315° C), and is nearly impermeable to water. That, however, is about to change.  Read More

Canadian startup Harvistor has tested its DARWIND5 vertical axis wind turbine and says it ...

Ontario, Canada has carved out a niche for itself as a hub of green technology. One of the latest clean tech innovations to come out of that province is DARWIND5, a vertical axis wind turbine (VAWT). Designed by Harvistor, it comes with a promise of more oomph than existing models for small-scale wind power generation. According to the company, recent tests showed that its technology can achieve 35 percent more kilowatt hours per year than current VAWTs for the same sweep area, besides operating at 25 percent lower heights than similarly priced market leaders.  Read More

Vestas has upped the capacity of ts V164 wind turbine to 8 MW

Danish wind turbine specialist Vestas was already looking to claim the title of the world’s largest offshore wind turbine with its proposed V164 that boasts a diameter of 164 m (538 ft). The company claims the V164 was developed with the potential of increasing its turbine size and now it has done just that, upping the capacity from seven to eight megawatts. So not only is the V164 set to boast the largest swept area of any single wind turbine, it will also claim the title for the world’s largest capacity wind turbine.  Read More

What's claimed to be the world's first fully integrated wind-powered electric vehicle charging station has just been unveiled in Barcelona, Spain. The Sanya Skypump marries a 4 kW turbine developed by New York's Urban Green Energy (UGE) and General Electric's (GE) WattStation charging technology to offer users the chance to juice up an EV using clean, renewable energy.  Read More

Revamping a concept that was first explored forty years ago, researchers at the University of Southern California (USC) are putting the final touches on a patent-pending design for cheap, rechargeable, high energy density iron-air batteries. Because of their unique features, the batteries look particularly well-suited to the kind of large-scale energy storage that could accelerate the adoption of renewable energy sources.  Read More

A Siemens B75 blade in its mold

Siemens has released pictures of its truly gargantuan B75 wind turbine rotor blades. As you might imagine, the prototype turbines that will use these blades boast some staggering statistics of their own (Airbuses at the ready, please).  Read More

Workers install a solar array in Tokelau, an island nation that will be powered with renew...

Adopting renewable energy sources such as solar and wind power is a great way to reduce emissions and produce energy locally. In places like remote Pacific islands, however, those benefits are potentially a key to independence. For that reason Tokelau, a 10 sq. km. (3.86 sq. mi) island nation that lies around 500 km (311 mi) north of Samoa and which is a territory of New Zealand, is about to ditch diesel as a source of electricity and switch to solar power.  Read More

The photoactive plastic panel is 70 percent transparent to visible light

A UCLA team has developed a new type of solar cell that is nearly 70 percent transparent to the naked eye. The plastic cells, which use infrared instead of visible light, are also more economical than other types of cells because they are made by an inexpensive polymer solution process and nanowire technology, potentially paving the way for cheaper solar windows.  Read More

The turbine is particularly well-suited to the gusting winds of inner cities

A new prototype wind turbine, 30 years in the making, and designed for flat-pack shipping and easy assembly, has been erected at Keele University in the UK.  Read More
