Data centers for AI are driving huge increases in electrical load, and there’s currently not enough power on the grid to match the projected growth. The Trump admin is now trying to promote new fossil gas generation as the solution, and there is no shortage of reasons to be concerned about this:

“Secretary Noem has overseen a reign of terror at DHS, harming communities across the country and resulting in the deaths of people who sought to hold the administration accountable," writes UCS's Dr. Jennifer Jones.

When it comes to data center development, we need policies, not pledges. Take a look at how some of the same tech companies who just signed Trump admin's non-binding “pledge” to protect ratepayers from data center costs are right now doing anything but. (🧵⬇️)

#EVs are a critical grid reliability and electricity affordability solution. New @latimes.com opinion piece calls for #EV investments to deliver benefits. #CALeg, @assemblydems.bsky.social, @casendems.bsky.social, use the budget to invest in EV car and truck incentives! #InvestInCleanAir

Today marks UCS’s 57th anniversary, and our President @gretchentg.bsky.social’s message feels more resonant than ever, given our long history of challenging the misuse of science and technology for military and war purposes.

1/ Last month, EPA announced it would expand reporting of one type of PFAS chemical in the Toxic Release Inventory (TRI), a public database of industry-reported chemical releases.

1/ Last week, Rep. Katherine Clark (@whipkclark.bsky.social) held her own state of the union with constituents, including Science Network members who shared the impacts of the Trump administration’s actions on science, public health, and democracy. (🧵👇)

The rising demand from data centers is greater than the utility industry has seen in anyone’s career. What is unraveling under this pressure, and what new opportunities are emerging from the crisis? UCS’s Mike Jacobs breaks it down in his blog:

No rational justification for dismantling the center has been offered," writes UCS President & CEO @gretchentg.bsky.social of plans to restructure @ncar-ucar.bsky.social.

President Trump’s illegal war of aggression against Iran, in cooperation with Israel, actively undermines global security, raises the long-term danger of nuclear proliferation, and risks dragging the US into another dangerous and protracted conflict. Read UCS’s statement: act.ucsusa.org/3N9e4ZE

🚨 The LCV Scorecard is here! Tracking votes on the most important environmental and democracy issues, @lcv.org gives each member of Congress a score from 0-100% based on how often they are voting in favor of people and the planet. Spread the word! 🔗👉 lcv.org/scorecard

1/ One year after the movement-defining Stand Up For Science protest, organizers are returning to the streets on SATURDAY MARCH 7th, 2026 to save science, protect health, and defend democracy!

Families deserve better. Children deserve better. The Senate hearing for Surgeon General nominee Casey Means proved she is wholly unqualified for the position, as she fails to support robust vaccination policies while giving credence to long-debunked science. (🧵👇)

Big Oil's top lobbying group, the American Petroleum Institute, has reported talking to members of Congress about draft legislation to stop state climate lawsuits. What a coincidence that Rep. Harriet Hageman happens to be drafting legislation to do exactly that. 🙄

This bill invests in proven strategies to bolster energy affordability...Yet [it] could be bolder. Massachusetts residents deserve more robust, equity-centered solutions from the legislature’s flagship energy affordability bill." Statement by UCS's Paula García:

The Trump administration plans to dismantle NSF’s National Center for Atmospheric Research, potentially closing its main lab in Boulder. UCS's @carlonimbus.bsky.social explains how NCAR keeps us safe and how you can help protect it. Take action: act.ucsusa.org/4ceWei9

🔎En la tercera parte de "El Crimen del Siglo", te contamos cómo la ciudadanía respondió cuando se hizo evidente el daño de los combustibles fósiles y desenmascaramos las tácticas de las compañías para negar su responsabilidad y frenar la acción frente al cambio climático: 🎧Escucha el podcast:

"Commissioners are elected with the mandate to protect ratepayers, but today they chose to prioritize a trillion dollar company (Meta) over Louisianans already struggling with expensive, unreliable energy." Statement:

Our partners at Lekeh Development Foundation (LEDEF) in Nigeria report on a devastating oil spill that occurred in Ogoniland in the Niger Delta in late December. They are calling for the government to remediate land & compensate affected people, and for polluting industries to be held accountable.

UCS’s Julie McNamara breaks down the impacts of repealing the Endangerment Finding and the legal fight we are joining to challenge that decision. “The only workable path ahead? Doubling down on commitment to action.”

Dr. Carlos Javier Martinez of @ucs.org states: “Scientifically, this decision by the Environmental Protection Agency is reckless, illogical and ignores the vast majority of public comments.”

🚜💧Las regiones agrícolas de California enfrentan inseguridad hídrica, calor extremo e inundaciones, entre muchos otros desafíos. Las soluciones basadas en la naturaleza ofrecen un enfoque eficaz para abordar estos retos.

1/ According to a recent analysis from the Brennan Center for Justice, 21 million voting-age Americans lack readily available citizenship documents such as passports or birth certificates. Restrictive ID laws could disenfranchise these voters. (A thread👇)

"As the costs of climate disasters climb, UCS's Shana Udvardy appears on the Disaster Zone podcast to discuss the turmoil at FEMA under the Trump administration and its withholding of funds for preparing communities for future disasters caused by flooding, wildfires and hurricanes."

2 years after we organized the largest-ever protests against Wall Street’s financing of fossil fuels, big banks’ financing of coal, oil, and gas is rising. What does this mean? As our director laid out in @bloomberg.com, it means protests alone aren’t enough. A 🧵: www.bloomberg.com/news/article...

What is AI and how does it work? UCS’s Samuel Dotson provides essential background for an informed discussion about artificial intelligence and its uses. This piece is part of UCS’s recent analysis, Data Center Power Play.

UCS’s Jen Jones joined @democracyforward.org to discuss their new report on the state of democracy, highlighting the work of the pro-democracy movement and offering a hopeful, aspirational perspective on the path ahead—and the role you can play. A must-watch ahead of tonight’s State of the Union.

Join us March 5th for a free educational webinar for Michiganders who want to learn more about hyperscale data centers as they arrive in their communities, presented by the Michigan Climate Action Network and the League of Women Voters of Michigan

Today #SCOTUS agreed to hear arguments from Suncor Energy & ExxonMobil challenging local govts’ ability to seek relief for climate change damages in state courts. Justice Alito, despite conflicts of interest leading to his recusal from similar petitions, refused to recuse himself in this instance.

Laura Peterson's blog shows how the largest publicly-owned oil & gas companies are leveraging AI demand to attract investors and financing while locking in fossil fuel infrastructure at a crucial moment for arresting climate change’s most harmful effects. But it’s not too late to disrupt this trend:

"Unfortunately, climate change has become a reality, and its impacts will be felt over the coming decades in the form of, among other things, more frequent and intense extreme weather events. We must prepare for this future, by making smart, science-informed investments in our electric grid..."

"This repeal blows wide open a toxic mercury emissions loophole for the dirtiest coal plants, weakens basic pollution protections, and discards requirements for coal- and oil-fired power plants to provide rudimentary operational transparency." Statement by UCS's Julie McNamara:

STARTING NOW: A 🇫🇷 court will hear a landmark case that could reshape corporate climate accountability in Europe & beyond. The Court will confront a defining question of our time: Can #FossilFuel expansion survive the rule of law in a climate crisis? Follow @duycks.bsky.social for live reporting! A🧵

Two big attacks on climate accountability lawsuits made the news last week -- and both were pushed by the Republican Attorneys General Association. Connecting the dots to some of RAGA's biggest funders: the same major oil industry players facing those lawsuits. www.exxonknews.org/p/the-top-co...

The Trump administration eliminated key environmental review step for experimental nuclear reactors. Critics: the move could undermine safety—especially at sites like Idaho National Laboratory. “Claiming you can just turn them on and not worry about impacts…that’s fantasy.” — Edwin Lyman, @ucs.org

“Dismantling these hard-won protections puts workers, first responders, and millions of people living at the fenceline of hazardous chemical plants in danger." Statement by UCS's @dminovi.bsky.social:

"As the housing and climate crises continue to merge, Congress’ final housing package must be as strong as possible to ensure greater housing affordability, stability, and resiliency. Unfortunately, parts of both bills fall short..." Read UCS's Zoe Middleton's blog to learn more:

"When outages disproportionately affect the same communities again and again, resilience ceases to be a technical challenge and becomes a question of responsibility," writes UCS's Sital Sathia in her new blog:

My wonderful @scovillepf.bsky.social @seantmanning.bsky.social has a great story in @inkstickmedia.com about biking alongside interstates during COVID. Those interstates could soon be carrying new plutonium "pits" - the radioactive core used in a new nuclear weapon: inkstickmedia.com/every-day-nu...

Data centers could be raising your utility bills—and putting your health at risk—to keep up with their hunger for power. Data centers are gobbling up entire cities' worth of energy, and too often, they're turning to toxic fossil fuels for power. (🧵⬇️)

SEE YOU IN COURT: UCS joined @earthjustice.org in a lawsuit against the Trump administration today to defend the EPA’s Endangerment Finding and vehicle emissions standards. Statement by UCS President & CEO @gretchentg.bsky.social: 🔗 act.ucsusa.org/4qLd8sf

“EPA’s repeal of the endangerment finding and safeguards to limit vehicle emissions marks a complete dereliction of the agency’s mission to protect people’s health and its legal obligation under the Clean Air Act,” said UCS President & CEO @gretchentg.bsky.social to @theguardian.com.

Earthjustice and our partners just filed a lawsuit to stop the Trump administration from making climate denialism official government policy.​ ​The endangerment finding requires the EPA to protect us from dangerous climate pollution that threatens our health and future. ​

"This shameful and dangerous action by the Trump administration and EPA Administrator Zeldin is rooted in falsehoods not facts and is entirely at odds with the public interest and the best available science."
