A gallon of gasoline contains 120,000 BTU to have you travel maybe 30 miles. 1 kilowatt hour of electricity is equal to 3,412 BTU, and will carry you 3-4 miles. 120,000 BTU for gasoline vs 34,120 BTU for electric. This isn't even close. #energytwitter #electrifyeverything

Next, regardless of parking lot ownership type, if the lot owner doesn't have a way to use the solar (like a net meter agreement with a utility), or access to a wholesale market (being able to sell directly into the grid), they won't recoup their costs.

About 3 million acres of parking lots exist in the U.S. It may take 20 acres of parking lots for 1 megawatt of solar. If 100% of parking lots were covered with solar, that'd be 148,187 MW. The U.S. uses 10x that amount of power - 1.3 million MW. We need more power.

First, parking lots are unusual things. They can be privately owned (a landlord), or publicly owned (city/school/etc.). Public owned lots/garages have to get budget line items through local/state appropriations. Private can go quicker, but still need permits, etc.

The average US new vehicle price now is $47k. Nearly all new cars are similar in price to EV's. EV sales increased nearly 50% last year from 1.6% to 2.9% of total market. #energytwitter

This is just silly. Georgia PSC staff asked Georgia Power for generation values for a power plant. Georgia Power redacted all the numbers because "trade secret". But the data are available publicly via the FERC Form 1. Gaston generated 2.7 billion kWh last year at $86.6/MWh.

Had a dream last night I was touring inside a floating 45 MW offshore wind turbine. Took an elevator up to the generator with a group. Passed a barber shop and dentistry inside the turbine on the way up.

What's your controversial #energytwitter take? Mine: if you've got LED's, turning the lights out isn't that important for saving energy. And leaving your TV/computer on is nbd.

After years of work, and numerous model runs, I'm finally publishing my work on #energytwitter and one possible alternative optimization scenario. Some said it could never be done. Some say I'm a dreamer, but I'm not the only one.

Most folks opposed to renewable energy use the average capacity factors as a "gotcha" - solar only produces 25% of the time! wind is at best 45%! these are not serious people Natural gas combustion turbines often are <10% capacity factor on an annual basis.

Impressive! Heat pump all-in-one washer/dryer that runs on a 120v socket. It's expensive at $2,900, but you don't need to install a new 240v line, nor buy two appliances.

We’ve been trying to get you all comfortable with EVs for a while now, but maybe we were just speaking the wrong language. A THREAD 🧡

At the Georgia Power IRP hearing today. Public comment is occurring and this high school sophomore is describing the benefits of the Inflation Reduction Act in reducing renewable energy costs.

The Southeast blackouts that happened b/c of Winter Storm #Elliott are going to cause a lot of soul searching because we don't have enough renewables to blame the outages on. Read that again. #energytwitter

Instead of hoping the power grid holds up, let’s fix the grid so we know it'll hold up.
