An anonymous reader quotes a report from The Guardian: Technology that harnesses wave energy through a “blowhole” is being tested at a remote Tasmanian island in a project backed by federal grants and investors. When the mostly above-water unit is connected in about a month, King Island in Bass Strait will be powered by three renewables — wave, wind and solar….

Electric Cars Would Save America Huge Amounts of Energy
An anonymous reader shares an opinion piece from Bloomberg, written by Liam Denning and Elaine He: Electrifying U.S. vehicles wipes out the equivalent of our entire current power demand. The U.S. consumes a lot of energy; last year, about 100 quadrillion BTUs (equivalent to 17 billion barrels of oil; which, we’ll admit, is only marginally less abstract). But only about a…
New Study: A Zero-Emissions America is Now Pretty Cheap
“Until recently, it was unclear whether variable renewable energy, nuclear, or fossil fuel with carbon capture and storage would become the main form of generation in a decarbonized electricity system,” argues a recently-published analysis titled Carbon-Neutral Pathways for the United States. “The cost decline of variable renewable energy over the last few years, however, has definitively changed the situation.” Ars Technica…
A 25-Year-Old Bet Comes Due: Has Tech Destroyed Society?
“Twenty five years ago I made a bet in the pages of Wired. It was a bet whether the world would collapse by the year 2020.” So writes the 68-year-old founding executive editor of Wired magazine, Kevin Kelly. He’d made the bet with a “Luddite-loving doomsayer,” according to Wired — author Kirkpatrick Sale. “Sale while a student in the 1950s co-wrote…
BP Slashes Its Oil Exploration Team by 85%, Starts Switching to Renewables
Reuters reports on big changes at BP (the company formerly known as British Petroleum):
Its geologists, engineers and scientists have been cut to less than 100 from a peak of more than 700 a few years ago, company sources told Reuters, part of a climate change-driven overhaul triggered last year by CEO Bernard Looney. “The winds have turned very chilly in the…
Are We Slowing Global Warming?
This week New York Magazine featured a new article by journalist David Wallace-Wells about the state of the fight against global warming. He warns that “Already, the planet is warmer, at just 1.2 degrees, than it has ever been…” But there’s also some good news:
Just a half-decade ago, it was widely believed that a “business as usual” emissions path would bring…
US Emissions In 2020 In Biggest Fall Since WWII
US greenhouse gas emissions tumbled below their 1990 level for the first-time last year as a result of the response to the coronavirus pandemic. The BBC reports: A preliminary assessment from research group Rhodium says that overall emissions were down over 10%, the largest fall since World War II. Transport suffered the biggest decline, with emissions down almost 15% over 2019….
Engineers Are Building Huge Salt Caves To Store Huge Amounts of Hydrogen
An anonymous reader quotes a report from Popular Mechanics: Scientists are going back to the salt mines, literally, to find a revolutionary new way to store large quantities of hydrogen for energy. Proponents say this could be a step toward unlocking hydrogen for renewables — something that could change the energy landscape if it were resolved. “The project would initially have…
It’s Official: Solar Is the Cheapest Electricity In History
An anonymous reader writes: In a new report, the International Energy Agency (IEA) says solar is now the cheapest form of electricity for utility companies to build. That’s thanks to risk-reducing financial policies around the world, the agency says, and it applies to locations with both the most favorable policies and the easiest access to financing. The report underlines how important…
One Solar/Wind Energy Company Is Now More Valuable Than Exxon Mobil
The world’s biggest provider of wind and solar energy is now more valuable than the giant oil company Exxon Mobil, “once the largest public company on Earth,” reports Bloomberg: NextEra ended Wednesday with market value of $145 billion, topping Exxon’s $142 billion… NextEra has emerged as the world’s most valuable utility, largely by betting big on renewables, especially wind. Exxon has…
