Fervo Energy geothermal plant

World’s biggest geothermal power purchase agreement completed in western U.S.

/

It’s only been one year since Fervo Energy unveiled a novel concept in geothermal energy harvesting at its Project Red pilot plant in Nevada. Now the company has signed a 15-year agreement with Southern California Edison to provide 320 MW of power to the utility, which will power about 350,000 homes. The power will be provided by Fervo’s Cape Station project that is currently being built in southwest Utah, with the first 70 MW coming online in 2026 and the balance clicking on in 2028.

E.U. surpasses 50% renewable power share for first time ever in first half of 2024

/

Electricity industry association Eurelectric has released figures showing that 50% of public electricity generation in the E.U. came from renewables for the first time in history earlier this year. The association said Europe was decarbonizing at an unprecedented pace, with just over 50% coming from renewable energy and nearly 75% coming from non-fossil-fuel sources, up from 68% last year.

Coal

Alberta’s last coal plant closes

/

Capital Power’s Genesee 2 facility — the last dedicated coal plant in the Canadian province — has officially gone offline. According to the latest forecast from the Alberta Electric System Operator (AESO), it’s not expected to come back online ever. As recently as 2001, coal accounted for as much as 80% of the electricity on the province’s grid.

For the first time, researchers detect significant dip in global atmospheric levels of HCFCs

/

Almost 30 years after nations first agreed to phase out these chemicals, which were widely used for air conditioning and refrigeration, scientists say global concentrations peaked in 2021. Since then, the ozone-depleting potential of HCFCs in the atmosphere has fallen by about three-quarters of a percentage point. Though small, that decline comes sooner than expected and represents a significant milestone for the international effort to preserve the ozone layer.

Portugal welcomes first wild bison in 10,000 years as part of plan to rewild a quarter-million acres

/

From Poland to Romania to the U.K., European wood bison are now firmly recognized as one of the best tools for returning what little wilderness Europe has left to as wild a state as possible. In Portugal, the gradual abandonment of the Greater Côa Valley has presented an unprecedented opportunity for rewilding in the small country. The government has already set aside a quarter million acres of land for conservation.

Vermont becomes first U.S. state to require oil companies to pay for climate change damages

/

Vermont has enacted a law requiring fossil fuel companies to pay a share of the damage caused by climate change after the state suffered catastrophic summer flooding and damage from other extreme weather. The funds could be used for upgrading stormwater drainage systems; upgrading roads, bridges and railroads; relocating, elevating or retrofitting sewage treatment plants; and making energy-efficient weatherization upgrades to public and private buildings.

Campesinos plant nearly a million trees in deforestation hotspot in the Colombian Amazon

More than 700 campesinos from the municipality of Cartagena del Chairá have started restoring more than 11,000 acres of degraded rainforest in one of Colombia’s deforestation hotspots. In collaboration with researchers from SINCHI, the Amazonian Scientific Research Institute, and the Association of Community Action Boards, the families have recorded more than 600 plant and more than 100 animal species in the area.

Cryo-cooling breakthrough slashes the energy cost of serious cold by 71%

/

Cryogenic cooling is used to preserve tissues, eggs, sperm, and embryos and CAT scanners, CERN’s massive particle accelerators, and the James Webb Space Telescope possible. It may also one day be the key to making fusion power or quantum computers a reality. However, it is also quite energy-intensive. Fortunately, researchers at the U.S.’s National Institute of Standards & Technology have recently discovered a way to reach near-absolute zero up to 3.5 times faster or using about 71% less energy.

‘Absolute miracle’ breakthrough provides recipe for zero-carbon cement

/

Concrete is the world’s most used building material, and making it is a particularly dirty business – concrete production alone is responsible for about 8% of total global CO2 emissions. But according to new research from the University of Cambridge, throwing old concrete into steel-processing furnaces not only purifies iron but produces “reactivated cement” as a byproduct. If done using renewable energy, the process could make for completely carbon-zero cement.
