I had some conversations yesterday about this - battery storage of all types and applications is still so young and prone to jumps in innovation I don’t think China necessarily has the same lead over the US as with solar. A more even & distributed global supply chain is possible

looking forward to this one... And this schtick between these two (Dave Roberts hates thinking about food; Mike G won't leave him alone about it) is hilarious...

This right here… If I had to do it all again… We need progressive & can do people in the electrical & HVAC trades! And design sectors. Perfect for high school go getters and 20/30-somethings alike, wanting to get wealthy at a good clip while saving the planet

This is what people don’t understand. All countries can produce electricity, many countries have to important refined oil products like gasoline and diesel using hard currency which is in limited supply. One in four vehicles sold this year will be EVs.

This is one of the most important space missions you could imagine. And it’s focused on Planet Earth, taking stock of our threatened forests.

I can get the appeal of a rather discrete/"bring your own cord" EV chargers, versus larger (garish?) plastic things. But I worry: 1) These designs are less accessible, being so low mounted. 2) Is it more of a tripping hazard if something isn't regularly there? 3) Brutal in snow

This study is fascinating. I would really love to see it overlaid with: 1. The current total GHG emissions from current grid interconnections (and the extent to which existing gas plants could make up the shortfall) 2. Human population

The official report on the blackout in Spain and Portugal was just released. I'll give a quick summary of findings and provide some additional info. TL;DR conventional power plants didn't control the voltage as planned over-voltage caused renewables to turn off as required

NEW: Cheaper batteries mean near-24/365 solar is now economic☀️ We analysed 18 years of hourly insolation data at 12 places, to see how close to 24/365 electricity it was possible to get. The sunniest places get over 90% - and up to 99% - of the way... from just $100/MWh. 🧵

The Earth Day protests in 1970 helped force the passage of the Clean Air Act, which has since saved millions of lives and trillions of dollars. Mass action works.

The best estimate we have for the number of anti-Trump protesters across the US yesterday: 11 million. 11,000,000: over 3% of the entire population took part! Thread on how Dutch @nieuws.nos.nl slowly moved from ignoring the protests, to putting the number at 100,000s, to "Organizers say millions".

Welp, this is super frustrating. Honestly, since senior levels of govt have shit the bed on enforcing/evolving anti-trust law, progressive cities and utilities may need to consider govt-owned options in some sectors.

About age 19, I was noodling around on the guitar on the ferry to Sunshine Coast. My sister says "Hey, you're getting pretty good". I say "Oh, I'm pretty good". Joni Mitchell turns around from the seat in front of us and does this huge scoff 😂

New research from my colleagues out today looking at the environmental and social impacts of food crop-based biofuels in the US, where we now use >30% of the corn supply and >40% of the soybean oil supply (on tens of millions of acres of prime cropland) to produce only ~6% of US transport fuel. 🧪
