True. In fact, China is building nuclear about as fast as the U.S. *ever* has. It's also true that in China, solar generation is growing >10x faster than nuclear.
Myth: Light-water nuclear reactors are too expensive and slow to build. Truth: China has spent the last decade rapidly expanding its nuclear fleet using large light-water reactors. These reactors only seem too expensive and slow to build in the US because of terrible policies!

Rick, I offered you an interview on separatism. You passed. Instead, you’re out here cosplaying as Alberta’s bravest keyboard warrior while carrying water for one of the dumbest ideas in modern Alberta politics. The old Rick would’ve had the guts to ask the questions himself. – at Calgary, Alberta

Good question! Coal produced 54.6% of China's electricity in 2025. Record-high wind & solar deployments raise rapidly the clean electricity share. And an EV running on 100% coal electricity would be cleaner than an oil-burner with 25 mpg fuel efficiency. EV is efficient!
@grok what percentage of Chinese EVs run on coal generated electricity?

Energy expert Dr. Lars Schernikau: It sounds simple… until you do the math. • 1 GWh battery = 700,000 tons of mined materials • Takes 450 GWh to build (450x its capacity) • Stores as much as 400 tons of coal Hours of storage. Massive mining, degradation & risks. This doesn’t fix intermittency, it multiplies the destruction. ‘Batteries are an environmental nightmare’.
Readers added context they thought people might want to know
Multiple numbers are wrong. Energy needed to produce 1 GWh batteries is 7 to 15 times smaller than claimed by Schernikau. no absolut number would be proof that batteries are an environmental nightmare compared to coal which Schernikau is lobbying for. Comparison is missing. research.chalmers.se/en/publication…

If you put that ethanol into the combustion engine of a car (that throws ~75% away as heat) and compare it with an electric vehicle, the end result becomes ~500:1 in favor of solar. And solar can go on roofs or be combined with other agricultural appliations.

The allegation of misuse of Alberta voters lists by separatists would be concerning at any time but it's doubly concerning at this time and on this issue. Political parties are entrusted with a great deal of information. And each piece - each voter contact - on its own, seems almost inconsequential. An address, a phone number - you can still find that in the white pages for most people. But as anyone over a certain age knows, not everyone is listed in the white pages, not everyone’s address is presented. The voter lists also include email addresses, and your presence on it or not strongly indicates citizenship status and other protected information. In 2026, the sheer volume of records is also a risk. That information, particularly in an environment where signatures are collected and then validated AGAINST the list, presents new opportunities to falsify signature collection. We do not know that has happened, to be clear. But Albertans now worry - if there’s reason to believe the data privacy rules were violated, what other rules are broken or bent? The citizen initiative signature acquisition process relies on trust - and for many, trust is now completely shattered. Albertans reasonably want assurances their data is protected. Albertans reasonably want assurances that the signatures captured are legitimate. At a minimum, Elections Alberta and the Alberta Legislature needs to be thinking about how these signatures are audited going forward. They should also consider how Albertans can assure themselves that their name has not been falsely added. This will add cost and complexity to the validation process. Maybe that cost and complexity is not worth it when the question is about daylight saving. But given the stakes of the separatists’ proposed referendum, that is a necessary cost. I also hope and expect, as an Albertan, that the authorities are on top of this. It is important that violations of our election laws, if any, are addressed - and that any loopholes that exist are closed, and trust is built back into the citizen initiative system.

To be clear, I want all three lines to go up. Factually speaking, solar is going to grow a lot faster.
Next is the part where solar pulls way ahead of the other two.

I am sorry you ordered your tanker wrap before the government paused the gas excise tax. But these are serious times and I am begging you to get serious.

Pierre, please draw me a map of how you got from "Trump disrupting free trade is a rupture and we must react" to "let's end free trade."
Pierre Poilievre: "He says he wants this rupture with the U.S. Does that mean he wants to pull out of the CUSMA? Because that's what a rupture would mean. Unless the word was just a meaningless sensationalist slogan."

Conservatives 🔵: you guys aren’t doing anything! Liberals 🔴: here’s the twenty new trade and security deals we’ve signed. 🔵: just paper, where are the results? 🔴: the share of exports heading to non-U.S. markets has increased by about 40%. 🔵: means nothing if it doesn’t help people. 🔴: agree, and in the past year wages have grown faster than inflation every month. 🔵: not everyone is seeing that wage growth. 🔴: it's true - which is why we’ve introduced targeted support such as the groceries and essentials benefit while the growth spreads more broadly. 🔵: we can’t afford those programs. 🔴: they’re temporary, and the IMF just said Canada has the best fiscal position in the G7. 🔴: there's lots more work to do, no-one is spiking the ball, and not everything is going or will go perfectly - but we're going to keep building a strong Canada for all. 🔵: [slinks off to cherry-pick data and complain about the last PM]

Three more things Peter Lougheed said about using the notwithstanding clause: 1⃣ "A simple majority does not appear adequate." 2⃣ "In my mind, [pre-empting judicial review] is undemocratic." 3⃣ “I would hope that the notwithstanding clause would be used very, very rarely.” Unfortunately, the Alberta government invoked the notwithstanding clause four times in the last year, each time pre-emptively, and each time with a simple majority, rather than the higher 60% threshold Lougheed preferred. Nobody is suggesting removing the notwithstanding clause. There are complicated constitutional issues at play but it is inaccurate and misleading to imply Peter Lougheed would support its use in a way he explicitly said he opposed. The courts are the appropriate place for these arguments.
The Notwithstanding Clause is integral to the Canadian Charter of Rights and Freedoms and an unassailable provincial constitutional right. Alberta Premier Peter Lougheed insisted it be included to protect the autonomy of provinces to uphold the values and priorities of the people they represent from decisions of activist courts. In Alberta, we have used it carefully and lawfully to stand up for the parental right to be involved in their children’s lives, to protect children so they can make important health decisions as adults, to ensure fairness in sport, and to keep students learning in the classroom. We are extremely disappointed that Minister Sean Fraser would risk national unity and a foundational principle of our constitution by attempting to attack the use of the notwithstanding clause by sovereign provincial governments.

There are only two certainties in life: death and Lomborg spinning anything into anti renewables propaganda. But the EIA has a track record of ridiculously underestimating EVs (which Lomborg knows and which is why he retweets them and not others). Let me quickly demonstrate.
US electric cars only win quickly if forced by environmental standards With regulation, 40-46% of all cars will be electric by 2050 Without regulation, 18% by 2050 Without regulation, most people still want gas cars at least till 2040 eia.gov/outlooks/aeo/pdf/AEO…

Southeast Asia is rapidly electrifying. Oil dependency makes you weak. Electric vehicles can run on domestic energy sources.
39 countries now have EV sales above a 10% share. In 2019, only four did. The impact is already clear: the global EV fleet avoided 1.7 million barrels of oil per day in 2025 – nearly matching Iran's entire exports through the Strait of Hormuz ⚡ 🔗ember-energy.org/latest-insi…

Critical support to killing every highway expansion project if it means getting one good highspeed rail line
"if it's such a great project why isn't the private sector financing it?" Why is this question valid for a train but never ever used for a road or a bridge?
