The cost of generating power from renewable energy sources has reached parity or dropped below the cost of fossil fuels for many technologies in many parts of the world, according to a new report released by the International Renewable Energy Agency (IRENA). The report, “Renewable Power Generation Costs in 2014”,... Read more →

The California Energy Commission approved nearly $18 million to fund projects that will help the state meet its climate and energy goals. Twelve million dollars will go toward three alternative fuel projects, $4 million will help fund two geothermal projects and $3.5 million will help fund local energy efficiency projects....
