The Global Alliance for 100% Renewable Energy recently called on European leaders to make firmer commitments to make a transition to renewable energy. The statement was made during the inauguration of the Alliance in Munich when member organizations stated that renewable energy has become the key to Europe’s future economic and industrial (more…)
According to the American Wind Energy Association, the last quarter of 2012 brought the total wind installations for 2012 to 13,131 megawatts of power.
This influx of new power extends the total of cumulative wind capacity for the United States to 60,007 megawatts. However, some states are much (more…)
What happens when there’s no wind and wind turbines stop turning? What provides the back up power for this clean energy source on calm, windless days?
One of the problems with wind power is that when there is no wind then there is no power. Offshore wind could provide abundant electricity — but as with solar energy, this power supply can be intermittent and unpredictable. A new approach from researchers at MIT could mitigate that problem, allowing the electricity generated by floating wind (more…)
Portugal generated more than 70 percent of its electricity from renewable sources of energy during the first quarter of 2013, a record amount fueled largely by hydroelectric and wind energy sources, according to a report from the country’s grid operator.
Hydroelectric generation provided 37 percent of the (more…)
The Danish capital is moving rapidly toward a zero-carbon future, as it erects wind farms, transforms its citywide heating systems, promotes energy efficiency, and lures more people out of their cars and onto public transportation and bikes.
Among the first sights to greet visitors to Denmark on (more…)
Here’s a good discussion of what I call the “no free lunch” theory of renewable energy: everything we do, whether it’s solar, wind, hydrokinetics, etc., comes with a non-negligible ecological cost. The issue, obviously, is objectively identifying all costs – ecological, financial, and human (e.g., disease and death stemming from various types of energy generation and consumption), (more…)
