Gibraltar to suck up 15 percent of its power from waves

While world leaders meet in Paris to discuss reducing carbon emissions believed to contribute to climate change, the government of Gibraltar is putting its own renewable energy plan into action. The iconic British territory has inked a deal with Eco Wave Power to install a 5-megawatt wave energy power station to harvest electricity from the rising and falling waters of the Mediterranean.

World’s first floating wind farm to be built off Scottish coast

In a deal between the Scottish government and Norwegian oil company Statoil, five wind turbines with a capacity of six megawatts each will be set on floating structures some 15 miles (25 km) off the northeast coast of Scotland near Peterhead. The Hywind pilot park, as it's named, is claimed to be the first floating wind farm in the world, and will generate enough power for 20,000 homes with operations expected to start in late 2017.Read More

World's largest second-use battery storage unit prepped for grid connection

As electric cars come towards the end of their life, they create a set of problems that you simply don't get with petrol cars - namely, getting rid of the batteries. Automotive giant Daimler is doing its bit to tackle the problem by partnering with The Mobility House, GETEC and Remondis to create a 13-MWh battery storage unit out of second-life battery systems from electric and plug-in hybrid cars.Read More

Energy storage advance readies concentrated solar power for the smart grid

The intermittent nature of renewable energy sources is a huge burden on the power grid, making flexible and economical energy storage an essential step to a greener future. Researchers at Oregon State University (OSU) and the University of Florida have now devised a way to conveniently store and release energy harvested through concentrated solar power (CSP) plants, improving on the cost and energy density of previous systems and preparing this technology for the smart grid.Read More

Advanced solar-powered cars gear up for grueling World Solar Challenge

If you're looking to bring together the world's brightest budding engineers to push solar technology to its very limits, then there may be no better backdrop than the dusty, sun-drenched expanses of central Australia. The biennial World Solar Challenge will kick off this Sunday, with competitors set to cover a monster 3,000 km (1,864 mi) journey from Darwin, Northern Territory to Adelaide, South Australia in cars powered purely by the sun. As hopefuls from all over the globe ready their rides for the ultimate in solar-powered endurance racing, here's a quick look at some of the interesting vehicle designs, who's new to the party and a few that have been around the block before.Read More

Hybrid solar roofing system uses heat pipes to boost efficiency

You would think that the more sunlight that hits a solar panel, the better. When it comes to efficiency though, that's not the case – as photovoltaic cells heat up their efficiency decreases. To capture that heat and put it to good use, a team of scientists from Brunel University London has created a hybrid system that turns the whole roof into a solar generator.

Breakthrough rectenna converts light into DC current

Rectifying antennas – "rectennas" – are used as parasitic power capture devices that absorb radio frequency (RF) energy and convert it into usable electrical power. Constructing such devices to absorb and rectify at optical wavelengths has proved impractical in the past, but the advent of carbon nanotubes and advances in microscopic manufacturing technology have allowed engineers at the Georgia Institute of Technology to create rectennas that capture and convert light to direct electrical current. The researchers believe that their creation may eventually help double the efficiency of solar energy harvesting. Read More
