Last week, I was invited to testify at a Congressional hearing entitled Leading the Charge: Opportunities to Strengthen America’s Energy Reliability. It was held by the House Oversight Committee’s subcommittee on Economic Growth, Energy Policy, and Regulatory Affairs.
Ahead of the hearing, I submitted written testimony to the subcommittee. You can also watch the full hearing, including all the witness statements and the questions and answers afterwards. Here’s one exchange between Ranking Member Maxwell Frost (D, FL-10) and me.
Speaking at this hearing gave me the opportunity to share the facts on the economic, health and climate benefits of accelerating our nation’s transition to clean, reliable, affordable energy, drawing on insights from research done by UCS and others.
Unfortunately, other panelists used their time to boost fossil fuels, bash pollution standards for the power sector, and give full-throated endorsement to the Trump administration’s destructive actions to roll back climate and clean energy policies. One panelist even engaged in pointed anti-science rhetoric, questioning the reality and harmful impacts of human-caused climate change.
Here are my oral comments, as prepared in advance.
Good morning. Thank you, Chairman Burlison, Ranking Member Frost and members of the subcommittee for holding this hearing. My name is Rachel Cleetus. I am the policy director for the climate and energy program at the Union of Concerned Scientists, a non-partisan science advocacy organization.
I want to highlight three things today:
- Accelerating the transition of our electric system to one that’s modernized, more flexible, with more renewables and storage, is the best way to protect consumer’s pocketbooks as well as safeguard health, make sure that we’re competitive on the global stage and that we’re innovating as we go along. There are tremendous economic and health benefits from this transition.
- Doubling down on fossil fuels is harmful and it’s taking us in exactly the wrong direction. And there is ample evidence that natural gas price volatility is one of the factors driving increased electricity prices, as well that gas-fired power plants raise reliability concerns for the power grid.
- Today, in 2025, we should not ask any American to choose between their health and prosperity. We can have both and we should have both.
The solutions to many of the challenges we see today are clear: ramping up renewable, energy efficiency and storage, and investing in a modernized, more resilient electric grid will help cut power bills, boost business opportunities, and improve public health. Doubling down on fossils fuels will instead take us in exactly the wrong direction and only serves to promote the profits of fossil fuel companies at the expense of the American public.
Renewable energy sources are now the dominant source of new power generation capacity because, frankly, in many parts of the country they are the lowest-cost source of new electricity generation. They are also faster to build. Last year, renewables and battery storage accounted for 94% of all new large-scale capacity, with solar and battery storage leading the charge. In 2025, renewables are on track to supply 25% of electricity generation. Solar generating capacity is projected to increase 45% between 2024 and 2026.
The Inflation Reduction Act (IRA) and the Infrastructure Investment and Jobs Act (IIJA) provide critical funding for clean energy investments that are benefiting communities across the nation by expanding access to clean, affordable energy, building domestic manufacturing and supply chains, creating good paying jobs, and helping to limit pollution from fossil fuels. In the past year, U.S. investments in clean technologies reached $272 billion, crucial to keeping US businesses competitive in a world where greener products are increasingly in demand.
The current administration’s actions to claw back or freeze this funding are frankly unfathomable. It is creating disruptions and market uncertainty for businesses that are trying to lean into opportunities right now. It’s going to result in ceding U.S. leadership on technological advancement. It’s going to cut good paying jobs and, ultimately, it’s going to harm electric reliability and increase energy costs.
Trying to turn back the clock and boost fossil fuels makes no sense. Market factors continue to drive ongoing coal plant retirements. Meanwhile, an overreliance on natural gas and volatility in natural gas prices increase the risk of higher prices for industry and for consumers. A rush to further expand LNG exports is only going to exacerbate those risks. And in a carbon-constrained world, these kinds of projects are likely to become stranded assets.
Recent extreme weather events underscore that gas power plants face significant reliability concerns, with the most catastrophic failures occurring in winter. Worsening heat waves and drought are also putting pressure on the electric grid, especially during summer months. Hybrid systems that couple renewable energy with storage provide significant grid reliability services, often more effectively than gas generators. During the heat domes that we saw last year and the year before, it was solar plus storage that helped save the day.
The power sector does need to plan and prepare for increased demand both in the near-term from data centers and manufacturing and in the long term from increased electrification of energy uses. Managing and planning for this demand growth to align with the expansion of clean energy will be crucial to avoid electricity price increases, reliability concerns, and increases in pollution.
We already are at record fossil fuel highs, whether it comes to oil or LNG. There is no problem in terms of expansion of fossil fuels unfortunately, even as the climate crisis worsens. What we need to do instead is unleash clean renewable power, the transmission to go with it, and energy efficiency.
The grid is desperately in need of upgrades and expansion. It got a C minus grade from the American Society of Civil Engineers. During extreme weather and climate events we’ve seen power outages that affect millions of people and cause billions of dollars of damages every year. We do need to quickly expand investments in a resilient transmission system built for the future climate conditions that scientists are telling us are going to worsen. By significantly expanding these grid investments, we can integrate higher levels of renewable energy, provide reliability benefits, and help reduce electricity bills.
Modernizing the power sector also provides opportunities to clean up air, water and soil pollution from fossil fuel use. Targeted investments and programs for low-income communities and communities overburdened by pollution will help ensure that all communities can reap the benefits of a cleaner, more affordable, more modern energy system.
Burning fossil fuels is also the primary driver of human-caused climate change which is already exerting a deadly and costly toll on communities and businesses across the nation. UCS research shows that we can cut sharply heat-trapping emissions while delivering billions of dollars in consumer energy cost savings and public health benefits.
In sum, modernizing and cleaning up the power sector is vital for the U.S. economy and for its ability to compete globally. It’s also the best way to protect consumers’ pocketbooks and enhance the reliability of the power system.
