@bobfreling.bsky.social is way too kind and generous, but giving to @solarfund.bsky.social is a massively impactful way to provide critically needed electricity access.

The @billgates.bsky.social post on @cop30brazil.bsky.social raised a fire-storm for its false either-or view on climate change

The politics of renewables are getting stranger. โ€˜Sun Dayโ€™ celebrates them anyway. The national day of action on September 21 arrives at a time when clean energy is becoming more polarized.

Nice to see Grist reporter @kateyoder laying out the 'flipped economics' of clean energy -- now cheaper, faster and more jobs than fossil energy -- in advance of @climateweeknyc.bsky.social @theclimategroup.bsky.social
