Trump's approach to wind projects is whipsawing developers: He's letting through some, while cracking down on others. Here's why: bloomberg.com/news/articles/…

After a crackdown on wind projects, the White House is now also letting a select few through to pressure Democrats into supporting a sweeping permitting bill.

The data center boom could increase greenhouse gases so much that it reverses years of reductions in US power emissions, a new analysis finds bloomberg.com/news/articles/…
New US Data Centers Projected to Emit More Carbon Than All of Mexico

New US Data Centers Projected to Emit More Carbon Than All of Mexico

The boom is set to produce enough greenhouse gases to cancel out 15 years of declines in power-sector emissions, according to a Sierra Club analysis.

Two neighbors live less than 2,000 feet apart. One pays up to $500/month for electricity. The other averages $130. One has investor-owned National Grid. The other, a municipal utility. @PopovichN and I dug into America’s widening power-bill divide: bloomberg.com/graphics/2026-…
One Home’s Power Bill Is $500. A Half-Mile Away, It’s 70% Lower

One Home’s Power Bill Is $500. A Half-Mile Away, It’s 70% Lower

The stark difference reflects a growing national divide between investor-owned utilities and public power providers

The 10-yr just passed 5.3%. If legacy data center $DLR’s $18.6B in debt (ex-pfds) cost 5.3% their annual interest cost would be almost $1B, which would wipeout their LTM Operating Income. Refinancing risk is real for the legacy data centers. $EQIX $CSQR

“Most Democrats will want to see how things go on Nov. 3 and then do a reality check,” Huffman said. “If we’re on our way to a majority in one or both Houses, it makes no sense to fold our hand when we could wait a few months and have a much better deal early next year.”

Financing the AI buildout will total $10.3 trillion from 2025-2032, or an average of 3.63% of US GDP each year: study. That "would be larger relative to the economy than the major US canal, railroad, electrification, highway, & telecom investment booms" brookings.edu/articles/finan…

AI's data center boom could require 3.6% of GDP in annual investment through 2032, and financing is shifting toward structures that make risk harder to see.
