The main problem with using renewable energy sources is that they are not as reliable or consistent as traditional sources. This is especially true of wind energy, since wind turbines work at generating power until the wind is blowing, but stop once the wind stops. (more…)
The more widespread adoption of renewable sources of energy is at least in part hampered by our poor ability to store energy. But a team of MIT researchers has recently a made a breakthrough in developing a new battery system. This all-liquid battery system is more efficient at storing energy, and costs less to produce, than currently available solutions. The further development of this system and use could make solar and wind energy more attractive and therefore facilitate its wide scale adoption.

Daniel Connell, the creator of the SolarFlower has released another very useful DIY tutorial. This one is for building a wind turbine from scratch for only about $30 in material costs. The solution he proposes is a vertical axis wind turbine based on the Lenz2 lift+drag design.

The Federal Network Agency of Germany (Bundesnetzagentur) photovoltaic solar (PV) installation counts that set new records at 7.6 GW of PV power plants installed and connected to the grid.
The 50-megawatt solar power project First Solar has acquired from the solar division of Element Power is billed as the state’s largest and raises questions about solar energy as a commodity.
With a generating capacity of four megawatts and a rotor diameter of 130, the new design was launched at at the annual conference of the European Wind Energy Association (EWEA) in Vienna.
NRG Energy, Inc. announced its 66-megawatt (AC) photovoltaic facility has started commercial operation, which is now California’s largest fully operational solar plant.
Western Australia Greens have announced their $68 million plan for the installation of solar PV panels on roofs of public housing homes and apartments
The Scottish Government announced plans to invest over $1.8 billion in the next three years on climate change strategies with goals to “cut carbon emissions from electricity generation by more than four-fifths by 2030.”
The Spanish Wind Energy Association says that Spain’s wind farms produced more electricity than other power sources, delivering over 6 terawatt hours during January.
Minnesota Power, the state’s second-largest utility, will be phasing out coal production at two facilities and the Minnesota Public Utilities Commission ordered Otter Tail Power to stoop burning coal at one of their plants.
The UK Department for Business, Innovation and Skills (BIS) is investing £50m on six wind farms through a stake in a renewable energy fund.
