Over 40% of corn grown in Indiana is used to make ethanol that cars burn. One acre of corn yields about 16,500 vehicle-miles per year of ethanol, which sounds high until you realize that one acre of solar yields about 2,700,000 vehicle-miles per year: 16,000% more driving for a given plot of land.

First question. How much power will this drain from our system capacity? We are already talking about shortfalls the early 2030's. My guess is that the draw on our grid will be ENORMOUS. How will we meet that demand? By burning NATURAL GAS? #CleanEnergy

This made me laugh out loud. Maybe it's because ice fishing is popular in Manitoba. Maybe it's the donuts. 🍩 🎣

So GM is doing to the Bolt what McDonalds does with McRibs. GM is no longer a serious car company & they are doing their best to undermine the EV revolution in North America. So when their Chairman says we need to get rid of EV mandates, we should tell him to pound sand.

Chevy says the new Bolt will be sold for a 'limited time' only. I think that's a mistake.

The new Bolt isn't even out yet, and Chevy is already talking about its end, while simultaneously planning for high volumes. What gives?

Why we should NEVER let politicians decide science funding. Can you imagine anyone in the Trump administration signing off on research on freakish underground rodents from east Africa? Me neither. But naked mole rats reveal some of the key secrets to aging and cancer.

The historically volatile Texas grid was entirely stable this summer, despite extreme temperatures. Grid operators never once had to ask Texans to conserve energy or shut off their air conditioners.

Why? Solar & batteries. Want a stable grid? Try solar & batteries.

Solar and batteries had a record-setting, grid-stabilizing summer in…

Solar has set 17 power generation records in Texas so far this year, shoring up the grid alongside batteries as some gas plant developers step back.

I wish politicians wouldn't wait until they are former leaders to call for the right thing. The time to impose fossil fuel taxes is when you are sitting in office, not afterward. #EndFossilFuels

I am not sure I agree. The renewable energy economist Mark Jaccard warns us about climate insincere politicians, who feign interest in climate change, but present policies that do nothing. The Manitoba climate plan has all the hallmarks of climate insincerity. Nothing concrete, just vague promises.

Scott Forbes🇨🇦 @theecologyprof.bsky.social · 1d

But I am critical of this plan. There are no concrete policies, no short or medium-term benchmarks, nothing but flowery language and and a laundry list of vague promises far in the future. In short, a plan so they can say they are doing something without actually doing something. #ClimateInsincere

Brilliant move by Mr. Carney? Playing Lucy and the football with Keystone XL, a pipeline that will never be built. Will Charlie Brown (Trump / Smith) fall for it? It'll be cancelled by executive order on Day 1 by President Buttigieg / Whitmer / AOC / Pritzker / Newsome.

"reading the room properly"? In terms of public opinion, perhaps. In terms of the planet being on fire, no, he did not read anything 'properly'. The current moment absolutely does demand a full court press, and anyone saying otherwise is wrong.

He’s not a career politician so why did he want to get elected? He doesn’t need the job, right?

Perhaps he realizes that the current moment does not demand a full court press on climate change. I’m not saying he’s right to ignore it, but he definitely was reading the room properly.
