Meet the World's First Island Powered by an Off-Grid Renewable Energy System
A tiny, scenic island lying off Scotland's west coast is truly a model for sustainable, off-grid living. With no mainland electricity connection, the Isle of Eigg gets its electricity from the water, the wind and the sun.
After decades of using diesel generators, in February 2008 the residents of Eigg officially switched to their own renewable electricity supply, becoming the world's first community to launch an off-grid electric system.
The 12-square-mile island, with its small population of 105 residents, gets 'round-the-clock power via a combination of hydroelectric generators, wind turbines, a photovoltaic array and a bank of batteries. On days when renewable resources are low or during maintenance, two 80kW diesel generators provide backup.
"The set-up that we've got now will carry the island all day and put charge into the batteries for the evening," John Booth, the former director of the community-owned Eigg Electric company, told the BBC.
On days when there is a surplus of power—like when it's particularly windy or rainy—electric heaters automatically switch on in Eigg's church and community hall, which is ideal for keeping shared spaces warm throughout the winter.
This means "virtually no central heating in the system at all," Booth pointed out. "We don't charge for it because the whole community benefits."
As the BBC detailed, before making the transition to renewables, the island relied on noisy and expensive diesel generators that could only run for a few hours a day. But with the new power system, energy is available 24 hours a day.
Eigg residents are encouraged to use their power responsibly. Each house has a maximum use limit at any one time of 5kW, which is enough for an electric kettle and washing machine to run at the same time, or fifty 100w light bulbs. Businesses get 10kW. Residents are fined if they use too much power but meters help keep electricity use on track.
"The whole thing is run by and for the island," Booth said.
Researchers from all around the world—Brazil, Alaska and Malawi—have visited the isle to learn how the unique system can be adapted elsewhere.
The European Commission, the European Union's executive arm, announced Tuesday it has opened an in-depth investigation into Bayer's proposed $66 billion takeover of Monsanto over "concerns that the merger may reduce competition in areas such as pesticides, seeds and traits."
The controversial merger, if successful, will form the world's largest integrated seed and pesticide company.
U.S. Environmental Protection Agency (EPA) administrator Scott Pruitt appears in a video sponsored by the beef industry calling on farmers and ranchers to file official comments on a proposal to withdraw and rewrite the Obama-era "Waters of the United States" rule (or WOTUS) before the Aug. 28 deadline.
The National Cattlemen's Beef Association (NCBA) video was produced by the beef lobbying organization's policy division, Beltway Beef and was released last week. Notably, NCBA spent $117,375 in lobbying last year.
Two years ago, Stanford University professor Mark Jacobson and his collaborators published a widely circulated study that detailed how the U.S. can eliminate nuclear, biofuels and fossil fuels and transition to 100 percent renewable energy by 2050.
Now, in a paper published Wednesday in the new scientific journal Joule, Jacobson and 26 co-authors created clean energy roadmaps not just for the 50 United States, but for 139 individual countries.
The effects of climate change is inextricably linked to human health. The burning of fossil fuels releases carbon dioxide and other greenhouse gases that traps heat in the atmosphere, causing global temperatures to spike, air quality to worsen, all while fueling droughts, floods and storms that impact food and water security.

Energy Transfer Partners, owner of the Dakota Access pipeline, has filed a $300 million Racketeer Influenced and Corrupt Organizations (RICO) lawsuit against Greenpeace and other environmental groups for their activism against the long-contested North Dakota-to-Illinois project.
In its 187-page complaint, Energy Transfer alleges that "putative not-for-profits and rogue eco-terrorist groups who employ patterns of criminal activity and campaigns of misinformation to target legitimate companies and industries with fabricated environmental claims and other purported misconduct" caused the company to lose "billions of dollars."
In a study published Tuesday in the journal Environmental Research Letters, Harvard postdoctoral fellow Geoffrey Supran and professor Naomi Oreskes reviewed nearly 200 communications on climate change from the oil giant, including scientific research, internal company memos and paid editorial features in the New York Times.
The U.S. District Court of Appeals ruled 2-1 Tuesday saying that the Federal Environmental Energy Regulatory Commission (FERC) failed to adequately review the environmental impacts of the greenhouse gas (GHG) emissions of the fracked gas Sabal Trail pipeline, which runs more than 500 miles through Alabama, Georgia and Florida.
As ocean waters warm and acidify, corals across the globe are disappearing. Desperate to prevent the demise of these vital ecosystems, researchers have developed ways to "garden" corals, buying the oceans some much-needed time. University of Miami Rosenstiel School marine biologist Diego Lirman sat down with Josh Chamot of Nexus Media to describe the process and explain what's at stake. This interview has been edited for length and clarity.
