Following environmental and energy issues in Colorado for the Colorado Sun, while taking a few turns on the slopes. One-time Denver Postie, Bloomberg Newser and Neimaner.
Solar developers find tough sledding in some Colorado counites, but county and municipal officials fear a new Colorado Energy Office report on energy infrastructure siting is a prelude to an effort by the take primacy in approval project siting. coloradosun.com/2025/10/20/s...
Pushback by counties on solar projects is challenging climate goals, Colorado officials say
Colorado Energy Office research was tailored to aid governor in dictating solar siting, much as he has done with housing, trade groups say

Fifteen companies are working on small modular reactors in the U.S. Many will fail, one proponent says. In fact they have to so there's a winner or winners who can build on scale. SMRs may be the technology of the future, but not a solution to pressing power needs.

Small modular nuclear reactors are having a moment. Will they arrive in time for Pueblo?
Feds, the state, cities, counties, companies are looking at next-gen nuclear power. But no small modular reactors have been built in the US.

Pueblo County, Colorado is asking President Trump to order Xcel's Comanche coal-fired power plant to keep running until an adequate replacement is in place. The county says only a small modular nuclear reactor will "make it whole."

Pueblo County to President Trump: Keep our coal-burning Comanche Station making power indefinitely.
Big economic impacts are on the line as deadline to close Comanche nears. Pueblo County wonders if is punished for twice voting for Donald Trump.

The West has wind and solar resources what it doesn't have is transmission lines and it is a battle to build them. Especially true for Colorado which is the most isolated part of the Western Interconnection.

A coal-fired plant delay is a plant delayed. Seeing rising electricity costs and demand PacifiCorp delays the closure of four Wyo coal-fired plants, though a couple will be converted to natural gas. A real tension emerging between cost/demand and GHG reductions. cowboystatedaily.com/2025/01/08/r...

From Wood Mackenzie: “Never has the world witnessed the pace of growth or transformation of an energy system that China is currently achieving,” said Wood Mackenzie's Malcom Forbes-Cable. “By 2025, China's installed solar and wind capacity will exceed that of both Europe and North America.”

Last week Meta put out an RFP for nuclear plants to power its data centers. Google is looking to colocate renewable generation with its centers. There's also talk of colocating gas turbines. It looks like tech is seeing that it can't depend on the grid. www.canarymedia.com/articles/cle...
Google plans to build gigawatts of clean power and data centers…
Can tech giants overcome grid bottlenecks by locating data centers near new wind, solar, and battery projects? Google and Intersect Power intend to give…

Meta is looking to twin its data centers with nuclear power plants. Meanwhile, Chevron CEO has floated the idea of dedicated gas plants - off the grid - to power data centers. Looks like the industry knows it has a problem www.utilitydive.com/news/meta-se...
Meta seeks up to 4 GW of new nuclear power to help meet AI, sustainability objectives
The Facebook and Instagram parent aims to deploy new nuclear generation capacity to power its data centers beginning in the early 2030s, it said Tuesday.

Too much of a good thing? Xcel Energy ran out of money for its commercial energy efficiency programs, its EV rebates and now its residential battery rebates. Colo PUC today okayed moving $6.8 million from commercial solar to cover applications. Xcel says it's demand. Critics says it's management

How will the Trump administration affect pubic lands in Colorado? Two hard fought battles to limit oil and gas drilling in the Thompson Divide and the Uncompaghre are targets. State remediation and wildlife corridor priorities may also be at odds with new BLM guidance.

The energy transition. Ce n'est pas bon marche. The Colorado PUC is wrestling with projections from Xcel Energy that it will need $40 billion in new transmission and $42 billion in new distribution in the next 20 years + a $12.5 billion Clean Energy Plan + another 6.9 GW of new generation.
