Portugal just ran for 4 straight days entirely on renewable energy
By Peter Dockrill

As renewable energy matures into an ever more popular and cost-effective source of electricity, we’re getting used to seeing some historic achievements from nations that have ramped up their clean energy infrastructure – and the latest glory goes to Portugal.

Recent figures show that the country ran on renewable energy alone for four days straight this month, completing an extraordinary 107-hour run between Saturday morning, May 7, and early Wednesday evening, May 11. During this record-setting window, Portugal ran on solar, wind, and hydro electricity entirely, without needing to fall back on power sourced from its coal and natural gas plants.

The numbers, released by Portugal’s ZERO System Sustainable Land Association in collaboration with the Portuguese Renewable Energy Association (APREN), indicate that the nation has come a long way in terms of embracing clean energy in recent decades, and could stand to even improve its environmental credentials in the near future.

Scientists have developed a procedure to cheaply create hydrogen for fuel and oxygen gas

By Mark Shwartz -

Stanford University scientists have invented a low-cost water splitter that uses a single catalyst to produce both hydrogen and oxygen gas 24 hours a day, seven days a week.

The device, described in a study published June 23 in Nature Communications, could provide a renewable source of clean-burning hydrogen fuel for transportation and industry.

“We have developed a low-voltage, single-catalyst water splitter that continuously generates hydrogen and oxygen for more than 200 hours, an exciting world-record performance,” said study co-author Yi Cui, an associate professor of materials science and engineering at Stanford and of photon science at the SLAC National Accelerator Laboratory.

Scotland just generated more power than it needs from wind turbines alone
By Bec Crew

Last Sunday, Scotland achieved something great - for the first time on record, wind power alone generated 106 percent of Scotland’s electricity needs in a single day.

Environmental group WWF Scotland has just confirmed that on 7 August 2016, wind turbines in Scotland pumped 39,545 megawatt-hours (MWh) of electricity into the National Grid, while the nation’s homes, businesses, and industry needed just 37,202 MWh.

“While it’s not impossible that this has happened in the past, it’s certainly the first time since we began monitoring the data in 2015 that we’ve had all the relevant information to be able to confirm it,” WWF Scotland director Lang Banks told the Associated Press.
