Busting a Myth: Clean, Renewables Lower Electricity Prices 11 US states met 51-120% of their electricity demand for the year between mid 2024-2025 with just clean, renewable sources. Of these, 10 had electricity prices at least 2 c/kWh below the US avg https://t.co/7n04zT3OVi

After 10 mon of '25, ~7 mon (211 days) with WindWaterSolar powering >100% of CA's main grid for part of day And look: Little wind Sat day but still 100% WWS Gas down 18% v '24; 37% v '23 Demand down 2% v '24; 1.4% v '23 Solar up 15% v '24; 43% v '23 Batt up 56% v '24; 199% v '23

Our good friend @mzjacobson busts the myth that high renewables mean high prices. The opposite is true.

My talk to the Elders Climate Action Group on what is needed to transition the world to 100% clean, renewable, energy across all energy sectors; what has been done to date; and what rate countries, states, and the world are transitioning. Some surprises https://t.co/2oALNXVrLi

Another 6 days straight and 208 of 300 in 2025 with WindWaterSolar powering CA's main grid for part of the day CA 54.24% in-state WWS for all of 2025, 3.87% higher than last year's 50.37%. At this rate, CA will be 100% WWS 24/7/365 by 2036. Gas down 18.5% v '24 & 37.4% v '23

CCS is a technology that fails from technology & economics. It only is pushed by fossil fuel industry to pretend. @mzjacobson Opposite to projections of WWS.
Carbon Capture and Storage 😬 Seen over at the other place, posted by Ketan Joshi: “each blue line is what *should* have happened based on each report's planned state dates. Black line: what happened”

Just a reminder that the sun shines, the wind blows, the water flows, and the Earth creates heat every day 206 days in 2025 so far with WindWaterSolar exceeding 100% of demand for part of the day, averaging 3.9 among all 298 days And fossil gas is down 37.4% in 2 y

New paper on the much lower cost, even in different climate zones, of 100% renewable microgrids that include heat pumps, battery storage, hydrogen storage with fuel cells, and thermal-energy storage, vs microgrids powered by diesel generators. https://t.co/5mlY7mZsKK
