Colorado study says runoff timing is shifting
Michael Booth of The Colorado Sun reports on a Nature Water study published April 30 that finds warming in Colorado's Rio Grande headwaters is shifting runoff from snow toward rain and spreading the spring-summer peak flow window. Using 70 years of basin records, the researchers say the timing spread in some years ran about 10 days longer than average, and modeled results showed junior irrigators could receive roughly 20% less water while senior rights holders get about 12% more even when annual streamflow is unchanged.
Why it matters
Earlier and more variable runoff changes how water is allocated under Colorado's seniority-based rights system and complicates drought planning.

The Colorado Sun coverageFervo Energy plans a $1.8 billion IPO
Tik Root at Grist reports that geothermal developer Fervo Energy plans an initial public offering under ticker FRVO to raise about $1.8 billion for expansion. The company says it already runs a Nevada project serving about 2,600 homes and is building Cape Station in Utah, which is expected to produce more than 100 times that amount; Alphabet is among the backers with data-center power contracts.
Why it matters
A raise of this size could speed up firm, low-carbon power supply at a time of rising electricity demand.

Grist coverageDOE official elevates CO2 utilization
Carlos Anchondo at E&E News by POLITICO reports that DOE assistant secretary Kyle Haustveit told a Washington energy forum the Trump administration is prioritizing carbon utilization within carbon capture, use and storage. Haustveit described CO2 as a resource for manufactured goods and oil-field injection, and said the July-signed One Big Beautiful Bill Act levels incentives between utilization and geologic sequestration.
Why it matters
The administration's stance could steer federal carbon-capture investment toward utilization projects rather than storage-only pathways.

OPEN QUESTION
Will Colorado water rules change?
The study shows that runoff timing, not just total flow, is now shaping who gets water in shortage years.
OPEN QUESTION
Can Fervo scale fast enough?
The planned IPO will test whether capital markets can fund geothermal at the scale needed for firm clean power growth.
