I always think the hardest part of working in climate policy is understanding how grim the science is

Humanity heating planet faster than ever before, study finds Researchers identify sharp rise to about 0.35C every decade, after excluding natural fluctuations such as El NiΓ±o

It doesn’t matter whether the rate of global warming is increasing. It’ll never cease to amaze me that people don’t care that it’s happening at all. It should be the most alarming thing ever.

How extreme weather is leaving thousands of homes uninsurable In this week’s newsletter: The climate crisis is making insurance unaffordable for many – and it should worry all of us, even if we think we’re safe from floods, wildfires and hurricanes

America is about to find out what it means to build domestic policy around an extremely volatile set of energy sources.

Meanwhile our biggest geopolitical rival shows the benefits of insulating an energy system from price shocks and exporting clean technologies.

Fixed it for you @washingtonpost.com

The Constitution gives election power to states. Federal control over elections is illegal. A fake emergency to steal control of voting is an attack on American freedom.

The Bay Area (where I used to live) and Denver (where I now live) both have versions on spare the air days when wood burning is discouraged. It’s a bigger deal than people realize!

Yup. I still remember the smell of wood smoke in my home and wish I hadn’t spent eight years breathing that into my developing lungs.

To be clear, millions of Americans use firewood for heating - including my childhood home - but that was the 1980s and we've got better options for today people to cut their energy bills.

Electricity prices are up 13% in a year but don’t worry, DOE has firewood prices locked down

Cool, solar added 25.4 GW, 18 GW of batteries, and 5.5 GW of wind. Is that more or less than 4.2 GW?

Surplus Interconnection: A fast, cost-effective strategy for bringing more renewable energy online
Surplus Interconnection: A fast, cost-effective strategy for bringing more renewable energy online YouTube video by Energy Innovation: Policy and Technology

Is America's solution to soaring energy demand hiding in plain view at retired coal plants or expensive gas plants that only run a couple hours a year?

Surplus interconnection could plug renewables into the grid without needing to build new transmission lines

Congressional β€˜grid reliability’ bill is like duct tape on a cracked dam Propping up expensive, dirty power plants threatens consumers with higher prices while punting systemic solutions further into the future, write colleagues fromΒ Energy Innovation.

What if the government said the best way to fix a failing dam was slapping duct tape on its cracks?

That's what the House "Power Plant Reliability Act" would do for America's grid - keep our least reliable generation online instead of fixing the actual problem.

US renewables boom despite Trump attacks Wind power in particular is soaring even as President Donald Trump disparages it.

More than 99% of the new electricity generation capacity built in America in 2026 will be renewables and storage.

Why? America needs cheap electricity now, and they're the cheapest available and fastest-to-build source of power, not coal or gas or nuclear.

Truly remarkable news from China - solar power capacity will surpass coal power capacity this year.

The world's largest emitter, and likely where the world's climate fate will be decided, is now driving the global clean energy transition.

Obama could be on Lake Street or Central today or any day over the past two months, saying something and making a scene.

He could have done the same in Little Village or anywhere else in Chicago.

But he's not here, wasn't there, and isn't helping.

Coal + gas fail once again during a winter storm.

20GW of generation went offline in America's largest grid during Winter Storm Fern.

DOE's policies to keep old coal plants running + expand gas dependency make our grid LESS RELIABLE + risk MORE BLACKOUTS

The thing about America today is that if you just describe what is happening objectively and unemotionally you sound hysterical and partisan and what you have to remind people is that the reason for that is not you, it's the people doing the things you are describing
