Three French Initiatives To Produce More Than 2600 Megawatts In Renewable Energy

The European Commission recently endorsed three French schemes to support solar and hydropower energy generators in France under EU state aid rules. The schemes will allow France to develop around 2600 megawatts of additional solar capacity and 60 megawatts of additional hydropower capacity. The two solar schemes together have [...]

Time to RE:think the economy!

“The root problem is the fact that our economic system demands ever-increasing levels of extraction, production and consumption. Our politicians tell us that we need to keep the global economy growing at more than 3% each year – the minimum necessary for large firms to make aggregate profits. That means every 20 years we need to double the size of the global economy – double the cars, double the fishing, double the mining, double the McFlurries and double the iPads. And then double them again over the next 20 years from their already doubled state??”

These 21 countries are cutting carbon while growing GDP

Several large, developed countries are breaking the mold of one-to-one economic growth and environmental impacts. As countries embark on the transition to a new climate economy , there’s a debate about whether growth can drive, or even coexist with, climate stabilization. This emerging trend is supported by 21 countries that have managed to reduce GHG emissions while growing GDP [...]

Global wind power capacity tops nuclear energy for first time

The capacity of wind power generation worldwide reached 432.42 gigawatts (GW) at the end of 2015, up 17 percent from a year earlier and surpassing nuclear energy for the first time, according to data released by global industry bodies.

The generation capacity of wind farms newly built in 2015 was a record 63.01 GW, corresponding to about 60 nuclear reactors, according to the Global Wind Energy Council based in Brussels. The global nuclear power generation capacity was 382.55 GW as of Jan. 1, 2016, the London-based World Nuclear Association said.

China overtakes EU to become global wind power leader

 

Booming market grew 27% in 2015 edging past European Union for first time. China installed half of all new wind capacity worldwide last year, according to the Global Wind Energy Council (GWEC). The country added an “astonishing” 30.5 gigawatts to boost installations to 145.1GW. Total global capacity reached 432.4 GW, a 17% increase on the previous year.

Rapid, affordable energy transformation possible, study says

The United States could slash greenhouse gas emissions from power production by up to 78 percent below 1990 levels within 15 years while meeting increased demand, according to a new study by NOAA and University of Colorado Boulder researchers.

Harvesting more energy from photons, leading to better solar cells

Researchers at MIT and elsewhere have found a way to significantly boost the energy that can be harnessed from sunlight, a finding that could lead to better solar cells or light detectors. The surprising finding is reported this week in the journal Physical Review Letters by authors including MIT’s Nicholas Fang, an associate professor of mechanical engineering, and postdoc Dafei Jin.
