For scientists, it should go without saying that the case for or against GWP-20 should rest on the merits of the metric, not on whether we like the policy outcomes it produces. howarthlab.org/docs/GWP20_imp…

One way you know the interconnection process is broken? Re-connecting a power plant that was online as recently as 2019 takes until... 2031.

China vs US grid thread. Just to calibrate things. To get things started - China's total electricity demand grew faster than the rest of the world combined (2024). /1

only Supercharger station within 40 miles on a snowy drive through rural Vermont. Customer service said these events are random and there’s nothing they can do to override or even predict them. Honestly, what a horrifying consumer product!

Learned about a new @Tesla feature today where they randomly take chargers off their network for non-Tesla owners. Happened to us first at the Level 2 charger that we rely on at our apartment (we thought there was something wrong with the app) and now (higher stakes) at the…

Hey, want to do electricity policy on the hill for a year? This will be a great experience. Apply by January 9 to IEEE's new Congressional Electric Grid Fellowship program! #gridfel" target="_blank" rel="nofollow noopener">ieeeusa.org/public-policy/…

Energy costs have tracked inflation historically. That stability is now at risk after scores of projects across every source were cancelled over past decade due to permitting. Without reform, we will not have affordable & reliable energy. A partial list of projects affected: 🧵

🚨 New Right of Way: We are, as they say, so back. Episode 3 with grid guru @DanielPalken is live! This one is all about transmission: the basics, bottlenecks to buildout, and a deep dive into past reform efforts & why they came up short.

“The peak in the summer of course is in the afternoon at the peak heat when air conditioning load is at its highest. Solar energy is very well suited to help support that. Energy storage resource is very well positioned to help during the evening ramps…

“A little over 9,000 megawatts of new energy coming online, new supply. The bulk of that is in the solar and energy storage categories, overall 9,000 megawatts between the two. Those are extremely helpful during the summer seasons…

@xiaowang1984 So if you're curious I think the general answer (for arbitrary CoPs of the 2 heat pumps C_W and C_A) is (C_A*C_W - C_A + C_W)/(2*C_W-1)

@xiaowang1984 I see, now I understand what you were asking. That's the same answer as mine if you plug in P_A/P_W = (C_W-1)/C_W (and set C_W = C_A = 3), which is the power ratio you get if you are running the heat pump enough to replenish the heat taken out of the air by the hpwh.

Question for the thermo ppl. If you have a heat pump water heater at COP 3 pumping cold air into a space that is also treated by a cop 3 air source heat pump what is the effective COP of the water heater?
