Australia’s leading scientists made a significant global-scale declaration about the fight to deal with the climate crisis this week – but you could be forgiven if you missed it.  In what it described as a landmark report, the Australian Academy of Science painted a picture of what could happen to the country under 3C of global heating, including ecosystems made unrecognisable, food production being compromised and people’s ability to exist and survive in hotter and longer heatwaves regularly tested.  The central message? There is no time to wait.  But lying within the report was another substantial claim – that limiting global heating to 1.5° C was now “virtually impossible”. - Guardian

When an oil or gas well reaches the end of its lifespan, it must be plugged. If it isn’t, the well might leak toxic chemicals into groundwater and spew methane, carbon dioxide and other pollutants into the atmosphere for years on end.  But plugging a well is no simple task. Cement must be pumped down into it to block the opening, and the tubes connecting it to tanks or pipelines must be removed, along with all the other onsite equipment. Then the top of the well has to be chopped off near the surface and plugged again, and the area around the rig must be cleaned up.  There are nearly 60,000 unplugged wells in Colorado in need of this treatment — each costing >$100,000. Plugging this many wells will cost more billions. - HCN

French energy company Total aims to have 100 gigawatts (GW) of gross wind and solar energy generation capacity by 2030, making it a frontrunner among oil giants shifting into renewables.  In comparison, Shell hasn’t set a target, as it says it’s focusing on green power sales, and BP’s target is 50 GW by 2030. Italy-based Enel leads, as it has a 145 GW target and says it wants to be a “renewables supermajor.” Total’s CEO Patrick Pouyanne said today that “in 2030, [Total] will have invested in 100 gigawatts of gross capacities; this is the objective and it will be spread in … 30 countries around the world.” - Electrek

With millions of Texas residents still without power amid frigid temperatures, conservative commentators have falsely claimed that wind turbines and solar energy were primarily to blame.  “We should never build another wind turbine in Texas,” read a Tuesday Facebook ost from Texas Agriculture Commissioner Sid Miller. “The experiment failed big time.”  “This is a perfect example of the need for reliable energy sources like natural gas & coal,” tweeted U.S. Sen. Steve Daines, a Republican from Montana, on Tuesday. In reality, failures in natural gas, coal and nuclear energy systems were responsible for nearly twice as many outages as frozen wind turbines and solar panels, the Electric Reliability Council of Texas, which operates the state’s power grid, said in a press conference Tuesday.  Still a variety of misleading claims spread on social media around renewable energy, with wind turbines and the Green New Deal getting much of the attention.  A viral photo of a helicopter de-icing a wind turbine was shared with claims it showed a “chemical” solution being applied to one of the massive wind generators in Texas. The only problem? The photo was taken in Sweden years ago, not in the U.S. in 2021. The helicopter sprayed hot water onto the wind turbine, not chemicals. - ABC News

"Most of the generation lost has been from coal and gas, according to ERCOT, with only 13% attributable to wind. 'By some estimates,' The Texas Tribune reported Tuesday, 'nearly half of the state's natural gas production has screeched to a halt. Gathering lines freeze, and the wells get so cold that they can't produce,' Parker Fawcett, a natural gas analyst at S&P Global Platts, told the Tribune. 'And, pumps use electricity, so they're not even able to lift that gas and liquid, because there's no power to produce.'"

While ice has forced some turbines to shut down just as a brutal cold wave drives record electrify demand, that's been the least significant factor in the blackouts, according to Dan Woodfin, a senior director for ERCOT which operates the Texas grid.  The main factors?  Frozen instruments at natural gas, coal and even nuclear facilities as well as limited supplies of natural gas, he said.  "Natural gas pressure" in particular is one reason power is coming back slower than expected Tuesday, added Woodfin.
