U.S. Set to Reach 6 GW Offshore Wind by 2027
Despite Trump, the U.S. will have 6 GW of offshore wind operating by 2027 All 5 developers have won court victories to complete their projects. 72% (4.3 GW) of the 6 GW are already installed or operational https://www.offshorewindca.org/maps
U.S. Grid‑Battery Output to Power All Renewables by 2026
U.S. grid-battery production has gone from 0 in 2024 to 145 GWh/year by the end of 2026, enough to provide batteries to support all wind and solar in the U.S. https://t.co/faeAUzMjZ8
CAISO’s Rapid Battery, Solar, Wind Build‑out Drives 100% Renewable Grid
In the one year between April 8, 2025 and April 9, 2026, @CaliforniaISO installed 4.656 GW batteries 1.534 GW solar 0.308 GW wind bringing grid totals to 16.04 GW/64.16 GWh batteries, 22.577 GW solar 8.681 GW wind The CAISO queue is 17.1 GW batteries 19 GW solar 0.8 GW...
New Lithium Finds Slash Battery Costs, Accelerate 100% Renewable Shift
With the discovery of 30% more world lithium resources in one year, battery-electric vehicle and stationary battery storage prices should continue to drop rapidly, facilitating world electrification and the inevitable transition to 100% WindWaterSolar across all energy sectors.
World Lithium Reserves Surge, Fueling Full EV Transition
New data: no shortage of lithium in the world for a 100% WWS transition. @USGS says known world lithium resources increased by 30% in one year, from 115.1 in 2024 to 150 million tons in 2025. That is enough for 19 billion...
Renewables Cut Fossil Energy Use by Over Half
The use of primary energy on the vertical axis is an old trick by the fossil fuel industry to mislead people into thinking that one unit of fossils = one unit of renewables. In fact, one unit of primary energy...
Nuclear Power Advocates Fuel Proliferation, Not Solutions
In this 2010 TED talk, I highlighted the risk of nuclear weapons proliferation due to the spread of nuclear energy https://www.ted.com/talks/stewart_brand_mark_z_jacobson_debate_does_the_world_need_nuclear_energy The response was denial, obfuscation, and attacks. Yet, the cause of the war with Iran today is to prevent them from obtaining...
Fossil Firms Favor GWP100 to Dodge Real Climate Action
Fossil companies support GWP100 over GWP20 because GWP100 allows them to do nothing about air pollution or global warming-to continue spewing BC, CH4 & O3 precursors & proposing fake solutions to CO2 (carbon capture, direct air capture, blue H2, electro...
Strong Climate Champions Crucial for Clean Energy Policy
Bill McKibben highlights the need for strong climate and renewable energy champions in this terrific article on the CA and NY governors races and how GWP20 v GWP100 plays into it Clean energy needs actual champions https://substack.com/redirect/a647db33-72bf-4a23-aafb-bbbb61eef92b
Wind‑Water‑Solar Combo Powers Record Demand, Cuts Gas
This is why we use a combo of WindWaterSolar Wind breaks new CAISO output record - when it is needed - at night - at 10:40 PM on 4/8: 6.699 GW Ignoring batteries, WWS also met the highest % of 24-h demand...
GWP20: Faster Climate Action for Methane Benefits Health
GWP20 for methane greenhouse-gas accounting is good policy in NY State & beyond, as Prof. Bob Howarth and I explain in a response (https://t.co/86Dm2bq6zw) to a recent claim that GWP100 should be used instead Both California and New York...
Electrify Canada: $182 B Annual Savings, 61% Demand Cut
No, Canada will save $182 billion/year in private energy costs by eliminating the use of fossil fuels for energy, electrifying all energy, and providing the electricity with WindWaterSolar alone (this will also reduce energy needs 61%) https://t.co/hsOANrg3KG Here are the data https://t.co/79QTBYtPSu https://t.co/c3RjxqKhcO @AaronGunn
Electrify Canada: 61% Energy Cut, Zero Fossil, Nuclear
Can Canada eliminate fossil fuels and nuclear for all energy? Although Canada currently provides 63% of its electricity from wind-water-solar sources, electricity comprises only 21% of Canada’s total energy, so wind-water-solar provides only 13% of Canada’s total energy. However, if we...
Four-Hour Batteries Deliver 14-Hour Storage at 0.28¢/kWh
These data illustrate how concatenating 4-hour batteries, provides longer-term (in this case, 14 hours) of storage. In other words, 4-h batteries already provide long-duration storage, and the batteries are inexpensive (0.28 cents/kWh-grid-output for 15.8 GW/63.2 GWh of batteries)
Batteries Delivered 8% of California Grid, Costing 0.28¢/kWh
Yes, the sun does't shine at night, but batteries produced electricity every minute last night (4/4) as California set a new discharge record of 57.17 GWh/day. Batteries have met 8.01% of all main-grid demand in 2026 in the 4th-largest economy in...
