Wildpoldsried, Germany produces 500% of its energy from renewable sources

September 22nd, 2014 at 11:30 am » Comments Off

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 sky’s the limit for 3D printing solar panels

September 16th, 2014 at 12:35 pm » Comments Off

Solar cell printers. We’ve come a long way from the solar-powered calculator to waiting to see when innovators are going to give us solar-powered smartphones, where most of our calculators are these days.  While the average energy consumer is busy worrying about such everyday concerns, scientists at the Victorian Organic Solar Cell Consortium (VICOSC) are wondering how to […]

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 transparent solar cells can be used on windows, smartphone screens to produce solar energy

August 22nd, 2014 at 12:54 pm » Comments Off

Transparent solar cell. Developed by researchers in Michigan State University, a new material, called a transparent luminescent solar concentrator, can be used to cover anything that has a flat, clear surface. Transparent solar cell technology has been attempted before, but the energy the cells produced was poor and the materials they were made out of […]



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 […]



Design flaw turns solar plant into a death trap for birds

August 19th, 2014 at 9:54 am » Comments Off

Super-concentrated sunbeams from BrightSource Energy Plant are deadly for birds flying overhead. In February, the $2.2 billion BrightSource Energy Plant opened up in the Mojave Desert with good intentions: to harvest clean, sustainable solar power, by using 300 mirrors to reflect sunbeams onto a steam-producing water boiler. But a design flaw has turned the plant into a death trap […]
