Last month I started a Google Sheet called "So you want to Work in Climate" to make an art piece. It became a work of art itself with 417 resources! With the thousands of layoffs over the past few weeks, I thought it could be helpful to share again nicolekelner.substack.com/p/…

Since Putin’s invasion of Ukraine, 41% of inflation can be attributed to skyrocketing fossil fuel prices & the secondary effects of high energy prices on other consumer goods. Here’s how a moonshot for renewable energy will decrease inflation & save Americans money:

I’m so fired up for this partnership with @aurorasolarinc and to join forces with @solarsamrise @chhopper and their team in our shared journey towards #cleanenergy for all!
Here’s how: 🏡🏩 Make 25C+25D credits direct-pay for building electrification and rooftop solar. 🔋😎 Create manufacturing tax credits for solar, advanced batteries+wind power. 👩‍🏭🏭 Expand the 48C credit to traditional manufacturing facilities that reduce their climate pollution.

HARVARD JUST DIVESTED FROM FOSSIL FUELS. Because great activists never let up. They don't use the word 'divestment,' but they said they have no direct investments left, will make no new ones, and that their indirect investments are in 'runoff mode' and will be allowed to expire
