this is incredible stuff. most state DOTs would spend tens of billions on highway expansions to try and see numbers like this (that wouldn’t even pan out anyway thanks to induced demand lol)

LCOE is better though a bit more complex to calculate and explain. At a minimum the writer should acknowledge the limitations of $/kW comparison.

The language β€œmegawatt produced” is a tip off that the writer is missing nuance of capacity vs energy output.

A lot of people still don’t realize that dramatic cost reductions in geothermal is something happening *right now*, not theoretically in the future.

Here is a look at the cost numbers published by NREL every year for Deep Enhanced Geothermal. A 50% improvement in 2024 with a lot more to come.

But didn’t post so I have no proof.

Hooked on mobile gambling?

Oh, not yet? How about $1000 in free credit.

Yeah, no strings attached. Just wager $55,000 to collect.

I assume the question is about incremental peak demand growth each year.

Happy bike cleaners.

Recently took a couple volunteer shifts at β€˜Free Bikes 4 Kidz’ in Detroit.

Awesome organization cleaning and restoring thousands of bikes for new homes. They make it super easy to show up and help out. Can’t recommend it enough.

RenCen would lose two towers, add apartments, riverfront park under new proposal Dan Gilbert's real estate company envisions a rightsizing of Detroit's skyline icon for a new era of downtown living.

RenCen is a Detroit icon. I’m excited to see this plan to preserve some of the towers, redevelop with added housing, expand the river walk park area, and add new connected commercial space and amenities.

Redistrict tweet: Trump had one job in the final days: talk about the economy/border and tie Harris to Biden. And we're really talking about Puerto Rico and water fluoridation?

Redistrict tweet: Trump had one job in the final days: talk about the economy/border and tie Harris to Biden. And we're really talking about Puerto Rico and water fluoridation?

It’s of no political moment, but it still rankles me that the case in chief against Biden is essentially that he prioritized full employment post-pandemic, and despite low joblessness, inflation, gas prices, and border crossings headed into election day, his record is still dubious because of vibes.

Infographic comparing big ass pickup truck (with photoshopped Saudi Arabia flag and USSR emblem) to cheap ass bicycle (with photoshopped American flag).

WOKE transit vs PATRIOT transit

The truck:

Needs license/registration so the government can track you

Government regularly inspects it to legally drive

Legally forces you to pay Insurance so they can pay for other people's accidents

Fuel needs big government subsidies to stay under $5/gallon

Government can revoke privilege to drive anytime

The bike:

Not required to register

No inspection requirement

Bike insurance optional. Not required

No need for government subsidies

Biking privilege cannot be revoked

Am I missing something? Wouldn’t this be much more efficient if it were a ground source system?

Any advantages to an air source system of this scale? I would expect ground source to be much more efficient.

2022 Total System Electric Generation

This table from 2022 shows 34 TWh of thermal/unspecified imports vs 50 TWh of low carbon imports.

The amount of thermal imports surprises me. Maybe some is leakage from the CARB ETS?

Question for πŸ”ŒπŸ’‘ why does California import ~1/3 of its electricity and run its gas fleet at 25% capacity.

Are CA emission prices high enough to reduce local gas dispatch in favor of imports?

Any good analysis out there on gas capacity factors in CA?

Opinion | It Takes Too Many Studies for the Government to Do the Right Thing It takes too many studies for the government to do the right thing.

SunZia exemplifies how hard it is to build big new power lines in America β€” how long it takes, how expensive it can be, how bad that is for the planet & how urgently Congress needs to do something about it. Conceived in 2006, the project is now old enough to vote. πŸ”ŒπŸ’‘
