Global energy spending is on track to reach $3.4 trillion in 2026
Around $2.2 trillion of this is set to go to grids, storage, low-emissions fuels, nuclear, renewables, efficiency & electrification
And about $1.2 trillion goes to oil, natural gas & coal: iea.li/4x6k5IT

NEW: i dove deep into the plans for several massive power plants being built specifically to power data centers
crucially, they're designed much less efficiently than gas-fired power plants that are connected to the electric grid:

The Real Reason Data Center Gas Power Plants Are So Dirty
A massive new gas plant in Texas will be built with much less efficient technology than regular gas plants. It’s far from the only data center power project to rely on dirty turbines.

My entry into the warmest year discourse...
Over the years, I've used a couple of methods to estimate annual mean anomalies before they happen - using projected ENSO signals at the end of the previous year, or just from the relationship between the YTD data and the final annual average.

The new norm for Chicago, in addition to the “normal” pollution + heat. #climatechange
