Battery Prices Crater in 2025 | Good Climate News
A key pillar of the low-carbon energy system is falling into place as battery prices plunge, reports PV Magazine. Cheaper batteries allow for more wind and solar to be added to the grid, and make electric vehicles cheaper.
“…prices have fallen 8% since 2024 to $108/kWh, making them 93% lower than in 2010…Battery pack prices for stationary storage fell to $70/kWh in 2025, 45% lower than in 2024.”
2. Geothermal Startup Fervo Raises $462 Million
The world’s hottest geothermal startup has raised yet more funding to help expand operations, explains Canary Media. The company is currently building the world’s first Enhanced Geothermal System (EGS) plant in Utah and the nearly half-billion dollar Series E round will help it go further.
“The financing announced this week will enable the startup to continue building Cape Station and to start development on other project sites where Fervo is conducting rock and soil analyses…”
3. Sustainable Fuels Gain Bipartisan Support in US
A bill to help airlines switch to low-carbon Sustainable Aviation Fuels (SAFs) is attracting bipartisan support in the US Congress, relays The Wall Street Journal. The global nature of the airline business means the switch is inevitable, and it also presents economic opportunities for US farmers.
“SAF production could generate tens of thousands of jobs in construction, operations, agriculture and logistics, according to the lawmakers.”
4. EV Adoption Soars Outside US
Sales of electric vehicles (EVs) are soaring outside of the United States, notes Yale Climate Connections. China, Europe, and most of the developing world are quickly moving away from gasoline cars, even as progress in the US slows.
“EVs have accounted for only about 10% of car sales in the U.S. this year, compared to the 25% global average.”

5. The Coal Era Ends in Washington State
The last coal-burning power plant in Washington state will close at the end of December, heralds Power Mag. The plant will reopen in 2028 as a 700 MW gas-fired facility, which will have a reduced carbon impact.
“This project demonstrates the valuable role that legacy assets can play in supporting the State’s clean energy laws and system reliability in a cost-effective and timely fashion.”
6. Toxic Mineland Turned into Solar Farm
A municipality in Pennsylvania plans to build a large solar farm atop a contaminated former mining site, says Electrek. A 265 MW solar project will be integrated with cleanup efforts, and highlights how land use concerns can be mitigated by leveraging degraded land.
“Black Moshannon Solar is projected to generate more than $5 million in tax revenue for the Phillipsburg-Osceola Area School District.”
📈 Chart of the Week
The cost of turning half the output of a solar farm into dispatchable 24/7 generation has reached the rock-bottom price of $33/MWh, according to a recent analysis by energy think tank Ember.
The falling cost of batteries is the largest driver of this trend, which should shortly make solar + storage the dominant source of electricity generation in much of the world.
