This week Kenya set in motion the construction of Africa’s biggest wind power farm, near Laisamis, 550km north of Kenya’s capital Nairobi.
Engineers from Stanford have developed a state-by-state plan to convert U.S. to 100% clean, renewable energy by 2050.
Nice Architect, a Slovakian company, has created the ecocapsule, a new kind of super green micro dwelling. The ecocapsule is powered by a built-in wind turbine and solar cells, and its egg-like shape allows the collection of rainwater and dew.
A battery module built at Aquion’s plant in Pennsylvania. A new kind of battery that stores energy from solar and wind power cheaply and cleanly has hit the market. It is by far the cheapest of a new generation of large, long-lived batteries that could make it possible to rely heavily on intermittent, renewable energy […]
Even though wind power uses up to 14 times more iron, the world wins on a switch to low-carbon energy. A global low-carbon energy economy could actually double electricity supply by 2050, while also reducing air and water pollution, according to new research. The first ever global life-cycle assessment of clean energy sources shows that […]
Renewable energy shows an average price decline over the last 5 years of 78% for utility scale solar and 58% for wind. Lazard, an asset management firm, has a fascinating new analysis of renewable and other energy prices out. There are a huge number of insights in this, from an outside analyst whose primary interest is financial. […]
Inexpensive renewable sources will provide more energy than the world needs in less than 20 years. Leading consultants were skeptical about cellular phones in the 1980′s. McKinsey & Co. noted that the handsets were heavy, batteries didn’t last long, coverage was patchy, and the cost per minute was exorbitant. It predicted that in 20 years the total […]
Wildpoldsried produces 500% more energy than it needs. Wildpoldsried, Germany, a Bavarian village of about 2,600 residents, is leading the way in Germany’s extraordinary renewable energy transformation. The village has invested in a holistic range of renewable energy projects over the past 17 years that include 4,983 kWp of photovoltaics, five biogas facilities, 11 wind turbines and a hydropower system. As a result, the village […]
By the late 2020s or early 2030s renewables could be competing much more aggressively with the oil market. Kepler Chevreux, a French investment bank, has produced a fascinating analysis that has dramatic implications for the global oil industry. The investment bank estimates that $100 billion invested in either wind energy or solar energy – and […]
Solar is now the fastest growing segment in the energy business in the U.S. The energy storage era is upon us. States like California and New York have adapted energy policies that will make it possible to economically deploy storage systems, while technology advancements have boosted performance and trimmed costs. For the first time in […]
The worldwide market for submarine electrical cables has surged over the past decade. Eighty wind turbines are now under construction in the German North Sea. They will eventually generate enough power for some 400,000 homes. That power will travel via advanced cables buried along several miles of ocean floor, part of a growing move toward […]
