The #HomeEnergyChoiceAct just passed in California! It generates new home electrification incentives while reducing utility bills by avoiding unnecessary & unwanted gas line replacements, with no mandates or safety compromises. Thank you @asmmarcberman.bsky.social! earthjustice.org/press/2026/c...

if you can’t replace your stove, you can get a great little induction hot plate for about $100 mine handles all my pasta, soup, anything that needs boiling or simmering. boils faster than gas, holds a perfect simmer reducing gas use helps even if you can’t quit it

Heat pumps are air conditioners. And air conditioners are (unidirectional) heat pumps. Opposing access to AC for ostensibly "climate" reasons is shortsighted, as they are a key adaptation technology to prevent suffering even while we continue to work to reduce emissions.
