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…)
The winds of change are blowing strong in Spain. According to the Spanish Wind Energy Association (AEE), in January the country produced more than six terawatts of wind power, according to data released by grid operator Red Electrica de Espana.
It was the culmination of a three-month trend started (more…)
Unsubsidized wind power is now cheaper than electricity produced from new coal- and natural gas-fired power stations in Australia, according to an analysis by Bloomberg New Energy Finance.
The study said that electricity can be supplied from a new wind farm at a cost of 80 Australian dollars per (more…)
The continuing expansion of renewable energy technologies, advances in energy efficiency, and the rapid shift from coal to natural gas for generating electricity combined to bring down U.S. carbon dioxide emissions last year to their lowest levels since 1994, according to a report by Bloomberg New Energy Finance. (more…)
Two of the world’s largest wind turbines, with blades 60 meters (196 feet) long, have been installed off the Yorkshire coast, a sign of a growing trend toward producing colossal wind turbines to boost generating capacity.
The plant, which will use technology developed by Stuttgart-based SolarFuel, reportedly will produce (more…)
