How strong does the wind need to be for a wind turbine to work? Wind turbines will generally operate between 7mph (11km/h) and 56mph (90km/h). The efficiency is usually maximised at about 18mph (29km/h) and they

The European Commission’s ‘REPowerEU’ plan and the recent pledge by Germany, Belgium, the Netherlands and Denmark to reach a capacity of 150 GW offshore wind power are game-changers for the climate and European energy politics, write Kadri Simson and Dan Jørgensen. The Middelgru...
Active stall control- The blades in this type of power-control system are pitchable, like the blades in a pitch-controlled system. An active stall system reads the power output the way a pitch-controlled system does, but instead of pitching the blades out of alignment with the wind, it pi...
It is not possible to control when the sun shines or the wind blows, however. Therefore, 24/7 matching of the supply of wind and solar power to demand cannot occur the way that baseload-generating plants fueled by coal, natural gas, or nuclear power can. That creates a conundrum. Uti...
If you’re wondering how climate change will impact your home's value, here are a few ways: Homeowners insurance is no longer an afterthought for buyers. There will be less demand for waterfront homes. Homeowners are paying higher insurance premiums. There will be higher property taxes. The ...
"September 6 was a day of records for the Greek renewable sector: 81 percent of the total clean energy in the country was provided by wind and 60 percent of the total energy consumed was offered by clean renewable energy sources," said Ioannis Margaris, vice-chairman of ...
There are a few continental ridge areas, where the magma does spew out onto land; but most land volcanoes are produced by subduction zone volcanism and hot spot volcanism. When the solid rock changes form to a more liquid rock material, it becomes less dense than the surrounding solid rock....
