The future of solar power is bright, finds @tinymaddie.bsky.social
*Solar panels are cheap, and getting cheaper
*Batteries are good, and getting better
*Economic case for solar will overwhelm political apathy
In short, we're going to run the world on sunshine

Solar energy is going to power the world much sooner than you think
Solar electricity is growing rapidly, but can it really dominate the global energy system? Here is what it will take for us to power the planet on sunshine

I think this means the CO2 rise was even higher than forecast by the Met Office, but that's based on a different measure so I'll need @richardabetts.bsky.social to confirm

Get a heat pump, get a job installing insulation or selling EVs, go to local council meetings in support of bike lanes or solar parks or dense housing near public transport. Run for political office, or at least vote. Recommend flight-free holiday destinations to others. (Delete as applicable).
my takeaway from climate week nyc is that "climate storytelling" is a little too much "we must reimagine our deepest souls in relationship to mother nature and the moral abyss of the polycrisis into which we must now stare" and not enough "ok but get a heat pump"
