Rio Tinto signs contract for Australian grid’s first gigawatt scale solar project

Mining company Rio Tinto has signed a contract to buy all the electricity from what will be the biggest solar project on Australia’s main grid – a 1.1 GW facility near Gladstone in Queensland. Rio Tinto is seeking up to 4 GW of wind and solar to provide clean power to and guarantee the future of its three main assets in the region – the Boyne Island aluminium smelter, the Yarwun alumina refinery, and the Queensland alumina refinery. All three assets are now supplied by coal.

First ever space-to-Earth solar power mission succeeds

A landmark test of beaming solar power to Earth from a satellite has concluded successfully after a year-long mission. Led by scientists at the California Institute of Technology, the mission completed all three of its primary experiments to test key technology for such an endeavor. They included a new origami-inspired solar panel structure, different cell designs, and a microwave transmitter.

Leading heat pump manufacturers develop next-generation prototypes to withstand subfreezing weather

The U.S. Department of Energy has announced that four additional heat pump manufacturers successfully produced heat pump prototypes as part of the Residential Cold Climate Heat Pump (CCHP) Technology Challenge. Launched in 2021, this initiative brings together public and private sector stakeholders to address technical challenges and market barriers to adopting next-generation cold-climate heat pumps—a key clean energy technology that can potentially save households $500 a year or more on their utility bills while also slashing harmful carbon emissions.

Norway moves aggressively to curb cruise ship emissions to protect fjords

Starting in 2026, only ships powered by alternative fuels will be allowed to visit Norway’s fjords. Lawmakers want to protect the unique natural environment and stop marine diesel oil and mass tourism from damaging the climate. Some ships are now powered by liquefied natural gas (LNG), but that will no longer qualify as an acceptable fuel for cruise ships visiting the fjords of Norway.

Germany reports lowest carbon emissions since the 1950s

In 2023, GHG emissions in Germany fell to 673 million tons of carbon dioxide equivalent, according to Agora Energiewende. That is down 46% compared to the reference year of 1990 and the lowest level since the 1950s. At the same time, carbon emissions were about 49 million tons below the German national target of 722 million tons as specified by Germany’s Climate Protection Act and 73 million tons lower than the prior year.

Wind turbines

Offshore wind sites are delivering power to the grid for the first time in U.S. history

In December 2023, Danish wind energy developer Ørsted and the utility Eversource announced that their first turbine was sending electricity from what will be a 12-turbine wind farm, South Fork Wind, 35 miles east of Montauk Point, New York. Now, the joint owners of the Vineyard Wind project have announced the first electricity from one turbine at what will be a 62-turbine wind farm 15 miles off the coast of Massachusetts.
