At $0.79 per MWh (3/4 of a cent per kWh), yesterday was the cheapest daily average price for electricity in Alberta's power market history.
By a wide margin!
(And these are nominal prices, unadjusted for inflation...)

In 2024, investment is solar PV is set to grow to $500 billion, leading the transformation of the power sector
More money is now going into solar PV than all other electricity generation technologies combined

Today, utility-scale batteries paired with solar PV are already competitive with new coal plants in some countries like India
In just the next few years, batteries + solar will be cheaper than new natural gas plants in the US & new coal in China 👉 iea.li/3KeM9m3

Since 2010, battery costs have fallen by more than 90% — offering opportunities to cut emissions in road transport & electricity
In 2023, electric car sales rose to almost 14 million. And battery storage deployment in the power sector more than doubled 👉 iea.li/3KeLWzh

The pace of the transition to EVs will hinge on their cost
In China, more than 60% of electric cars sold in 2023 were already cheaper than conventional equivalents
Competition & innovation are expected to bring down prices in other major markets 👉 iea.li/3JGhzkS

ERCOT hit a new record for battery dispatch tonight at 3.2 GW.
This smashed the previous record set less than a year ago by over 1 GW (+47%).

Battery manufacturing capacity has more than tripled in the last 3 years
Completing all announced projects would be enough to meet demand to 2030 on our net zero path
But manufacturing is concentrated in only a few countries, creating supply chain risks: iea.li/4aQcy5g

In 2024, natural gas generation on an average April day in California hit a 7-year low.
This is a significant trend reversal from what we saw from 2021 to 2023 in CAISO.

The ERCOT grid set a new record today getting almost 73% of its electricity from wind and solar!
Remember when some folks said 20% would break it?

As we await Premier Danielle Smith's announcement creating farmlands and "viewscapes" where wind and solar power would be restricted

Here's the new BNEF solar forecast.
2023 🤯, 2024🤯🤯
For context: I added the black line, which is the record coal power plant capacity that the world installed in one year (107GW in 2015).. ☀️

Good grief man, we can barely enforce the length of our own meetings. Drive wherever you want, live wherever you want—we’re just trying to make sure people have grocery stores.
Total nonsense. People BUY or RENT their homes and have the right to work and play and school and eat and shop where ever they damn well please.
This is about control. Nothing more.
Council for @CityofEdmonton can FO.

Statcan put out some nice data on energy use, GDP, and GHG emissions today.

Can see some nice decoupling in the following charts… 1/4

Did you know, the wind doesn't always blow & the sun sets every night? I recently learned this, and so I did some digging on how we might manage an electricity grid with lots of wind & solar on it. I shared what I found w/@drvolts in his pod. You may enjoy volts.wtf/p/what-the-sun-isn…

Time to make 2023 updates to my annual “opinions about solar” thread.
If you like these, the second edition of my book, Solar Power Finance Without The Jargon, comes out very soon (just sent final proofs to publisher!)
