For years, people argued that there's no point in taking climate action unless China is onboard. I'm at a COP30 event where Chinese government officials and renewable industry reps are outlining the fast-paced renewable energy transition and long-term carbon neutrality plan. The story has flipped.

This kind of efficiency is super exciting!
I'm keen to see more deployment and greater independent validation. Looks like potential game changing stuff.

Skyven harnesses waste heat to get industrial steam at a COP of 6.5 (this highly depends on the quality of the waste heat stream). Powerful stuff!
Atmos Zero is at 2, but they eschew waste heat so they can have lower Capex and simple install.

This industrial heat pump is cheaper to run than a boiler. Yes,…
Skyven Technologies is making clean steam in a cost-effective way. The tech could boost efforts to decarbonize heavy industry.

Outrageous. A travesty in our province.

I’ll just take this opportunity to note that Jimmy Carter had solar panels on the White House roof. Elect Dems & take climate/air quality action, and USA will be more prosperous.
The US is the world's largest oil and gas producer. Yet, "China is now making more money from exporting green technology than America makes from exporting fossil fuels."

You heard it from Bjorn Lomborg… let’s just focus on electrifying everything to cost effectively eliminate air pollution. Don’t worry about this whole divisive climate thing…
This is really dumb and lazy, even for Bjorn.
Hey, B, what's the biggest cause of both air pollution and climate change? (burning stuff, mainly fossil fuels)
And what's causing forest fires to increase, dramatically raising air pollution? (climate change)

Critics of renewables often point to land use as a reason not to do wind & solar. Land use IS a real issue for all energy assets incl renewables unless onsite.
But what critics conveniently forget is huge land impact of fossil fuels. Aerial view of fracking sites in Texas. 👇
