Compressed air energy storage has been used for decades, but only at two facilities in Germany and Alabama, built before solar and wind started creating challenges for power grid operators.
“This is a pretty simple concept,” said Bobby Bailie, director of business development for energy storage at the German industrial firm Siemens. “You’re pushing air into a cavern, storing that energy. And at times when you need it, you pull it back out.”

Can a giant underground salt cave in the Utah desert hold a potential answer to Los Angeles’s growing sustainable energy needs? The Los Angeles Times digs into a new-old approach for storing energy in compressed air deposits deep underground. The compressed air, generated with the help of... View full entry
America's coal industry has already been left in the dust by natural gas. Now it's under immense pressure from the renewable energy boom.
The renewable energy sector had slightly more installed capacity than coal in April, according to a Federal Energy Regulatory Commission report.

Surging renewable energy production capabilities have finally overtopped coal-fired power production in the United States in recent months, a historic first. The milestone is the latest development in a decade-long slide for coal-fired energy production, which peaked in 2008. CNN reports that coal... View full entry
General Electric Co said on Friday it plans to demolish a large power plant it owns in California this year after only one-third of its useful life because the plant is no longer economically viable in a state where wind and solar supply a growing share of inexpensive electricity. — reuters.com
GE's Inland Empire Energy Center, a 750-megawatt natural gas-fueled plant located in Riverside County, California, built in 2009 is shutting down 20 years early. The culprit? Affordable wind and solar energy, which are surging in California, and outdated technology. On most days, California... View full entry
On Wednesday during NYC Climate Week, Lego announced they’d be re-releasing the LEGO Creator Expert Vestas Wind Turbine, developed in collaboration with wind company Vestas...This set stands 3 feet tall and contains 826 pieces, including one piece—a spruce tree—that is the first of Lego’s sustainable plant-based plastic pieces. The set also features adjustable and motorized turbine blades and a movable nacelle with aircraft warning lights. — Popular Mechanics
The world’s biggest offshore windfarm has officially opened in the Irish Sea, amid warnings that Brexit could increase costs for future projects.
Walney Extension, off the Cumbrian coast, spans an area the size of 20,000 football pitches and has a capacity of 659 megawatts, enough to power the equivalent of 590,000 homes.
The project is a sign of how dramatically wind technology has progressed in the past five years since the previous biggest, the London Array, was finished.
— The Guardian
The Walney Extension is made up of 87 turbines and has a total capacity of 659 MW, enough to power almost 600,000 homes in the UK. This makes it now the largest operational offshore wind farm, however with wind farm supersizing along the British coastline it may not hold the record for long. ... View full entry
Britain’s homes could be lit and powered by windfarms surrounding an artificial island deep out in the North Sea, under advanced plans by a Dutch energy network.
The radical proposal envisages an island being built to act as a hub for vast offshore windfarms that would eclipse today’s facilities in scale. Dogger Bank, 125km (78 miles) off the East Yorkshire coast, has been identified as a potentially windy and shallow site.
— The Guardian
Plans by TenneT, the Dutch power grid, aim to build a power hub potentially at Dogger Bank, a site in the North Sea, at a scale that far surpasses current offshore sites. A long-distance cable would send energy to the UK and Netherlands, with other countries possibly added later. Early studies... View full entry
Creative studio DFA is proposing a 712-foot public observation tower in Central Park that would double as a sustainable filtration system to clean the hazardous Jacqueline Kennedy Onassis Reservoir and turn it into a non-toxic, useable freshwater pond. Though meant to be temporary, the prefabricated tower would be the world’s tallest timber structure if completed, featuring a 56-foot-wide viewing platform and a glass oculus that showcases the tower’s functional elements. — 6sqft

While hard to imagine today, Paris’s most iconic monument was largely reviled when it was first built for the 1889 World’s Fair. On February 14, 1887, as construction was just beginning, a group of some of most notable Parisian artists, writers, architects and intellectuals – including... View full entry
