Solar and wind prices plunge below fossil fuel prices

October 13th, 2014 at 1:07 pm » Comments Off

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. […]



We are headed into an era of unlimited and free clean energy

September 29th, 2014 at 12:21 pm » Comments Off

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, Germany produces 500% of its energy from renewable sources

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 […]



$100B invested in wind or solar will produce more energy than oil

September 18th, 2014 at 10:56 am » Comments Off

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 […]



The next big challenge for energy storage

August 24th, 2014 at 8:19 am » Comments Off

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 […]



New offshore wind energy and transnational grid projects will boost use of submarine power cables

August 19th, 2014 at 10:24 am » Comments Off

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 […]
