“WHEN I was a student in the mid-1980s,” says Harry Atwater, “there were only a few megawatts of solar deployed worldwide. Enough to power a supermarket or something. Now, solar technology has a global output of about 500 gigawatts.”
Farms are the ideal setting for solar panels, new research suggests. According to the study, if just 1 percent of the world's farmland were converted to solar panels, the power generated would be enough to meet global electricity demands.
When the 720 km power cable from Norway to the UK made landfall two years ago it was hailed as the longest in the world. Now a Singaporean renewable energy company has plans for an undersea power line five times longer.
The most profitable corner of the booming U.S. solar industry isn’t making -- or even installing -- panels. It’s building the components that keep electricity flowing to the power grid. They’re called inverters, and the two companies that make the vast majority of premium ones in the U.S. reported their highest revenue ever in the second quarter, propelling their shares to record levels.

Derek Hanson, who lives in Lavon, Texas, paid $1,000 to reserve Tesla's solar roof-tiles, known as the Solar Roof, in September 2017. He wasn't given an installation timeline, but was told his odds of receiving a Solar Roof would have been better if he lived in California.
A földgáz jelenlegi kiemelkedően magas részaránya csökkenhet, a megújuló energiaforrások súlya pedig jelentősen emelkedhet a budapesti távhőszolgáltatásban a Főtáv tervei szerint, amitől várhatóan érdemben javulhat a fővárosi levegőminőség is.
A szénerőművek áramtermelésének részaránya 19 százalékkal csökkent az európai elektromos rendszerben az első félévben. Ez a legmeredekebb csökkenés, amit valaha feljegyeztek. A hirtelen esés részben a tartósan magas szénáraknak, illetve a megújuló energiaforrások növekvő részarányának köszönhető.
