A Greener Tomorrow: U.S. Utilities on Track To Be 100% Renewable by 2060

Battery Technology Renewable Energy Storage

U.S. utilities are leading the transition to 100% renewable electricity by 2060, surpassing state policies. A CU Boulder study finds that technological advancements and cost reductions are driving this trend, with utilities on track to achieve or exceed state goals. The industry’s efforts encompass all states, irrespective of their renewable policies or political orientation, but still lag behind the Biden Administration’s 2035 target.

Utilities in the United States have committed to switching entirely to renewable electricity by the year 2060. While state mandates have contributed to this shift, it is primarily the utilities that are spearheading this transition toward renewable energy.

“Many people feel the transition on the policy side isn’t going fast enough,” said Matthew Burgess, a CIRES fellow, CU Boulder assistant professor, and co-author of the paper published in the journal Climatic Change. “But the private sector is moving faster than we thought. A lot has to do with technology, costs going down, natural gas replacing coal, and renewables replacing fossil fuels—policy is not the only lever.”

Research Approach and Methodology

Grace Kroeger led the assessment for her honors thesis in Environmental Studies at CU Boulder, inspired by energy and sustainability work from an internship at a consulting firm.

“I wanted to look critically at what the people on the ground are doing,” said Kroeger. “For example, the companies that are responsible for the energy that we all use and consume.”

She and Burgess compared state renewable energy targets with utilities’ own goals. They looked at 30 years of data to assess what shifts utilities have made to achieve renewable energy standards, as well as what state-level goals may have pushed utilities to make changes.

Typically states use Renewable Portfolio Standards (RPS) and Clean Energy Standards (CES) to mandate changes, which vary across the country. Some states have none, some have aggressive policies, and some have easy, manageable goals.

They also looked at utilities’ own goals, generally published online. For example, Xcel Energy plans to reach 100% carbon-free electricity by 2050. The authors combined data into projections of when utilities are likely to fully decarbonize.

Surprising Findings: Industry Outpacing Policy

What they found may be surprising to some: Industry, overall, is outpacing policy. Utility companies are on track to meet or exceed the goals of states with stated policies and mandates, and the authors project the electric grid will decarbonize 100% by 2060, so long as utilities are true to their word. When nuclear is included in renewable energy portfolios, utilities will decarbonize even sooner, by 2050.

The study revealed another surprising finding: utility companies plan to decarbonize across the board, even in states without renewable policies or goals.

“For example, Southern Company has goals to decarbonize,” Kroeger said. “But the states the company operates in—Georgia, Mississippi, and Alabama—don’t have portfolio standards.”

There were differences between blue and red states, however. The authors found blue states tended to pass stricter renewable energy goals and policies. But even without mandates or standards, most states, including red ones, are still on track to decarbonize according to utilities’ goals.

The authors noted that the findings were based on what utilities have stated they plan to do in the future, which is not guaranteed. However, when looking at historical data, they found utilities have already transitioned to renewables and away from fossil fuels faster than planned.

Despite the good news, neither states nor utilities are on track to decarbonize as fast as the Biden Administration’s goal, announced in April: to eliminate fossil fuels from the U.S. energy sector by 2035. This announcement didn’t come with policy or mandates to aid a transition.

“There’s a lot of really interesting stuff happening in the private sector,” said Burgess. “The private sector creates interesting decarbonization connections across states, and it has interesting connections to the policy space.”

  1. Goals are quite different from ability. For example, the UK banned the sale of petrol and diesel cars by 2030. That changed to 2035. Expect that to continue changing indefinitely, at least until nuclear fusion power is inexpensive. This study’s authors maybe shocked to learn politicians and corporate public relations sometimes provide an untruthfully optimistic vision.

    A similar but more-practical study came out two days ago actually, “When energy doesn’t add up: use of an energyshed framework in assessing progress towards renewable energy transitions” (Environmental Research: Infrastructure and Sustainability, Volume 4, Number 1. Jan 18, 2024). They studied 250 American cities and states with 100% renewable goals ranging between 2020 and 2050. They found the goals to be approximately 100% impossible. Instead, the majority will hit 10% within the next three decades, with best cases between 35% and 65%.

    “However, when looking at historical data, they found utilities have already transitioned to renewables and away from fossil fuels faster than planned.”

    How strange, that these learned intellectuals didn’t lift a finger to determine the effect that the last decade’s policies by State and Federal governments – to subsidize the profit-hungry private energy companies for their decarbonizing behavior – had on their actions.

    Said learned intellectuals might be connected with those who run our ‘news’ media, who go to some lengths to ignore those taxpayer-gouging policies of subsidization while promoting public fears of global warming.

    Somehow, it doesn’t pay to rely on learned intellectuals 100% of the time.

  3. Good to know the utilities are FINALLY going nuclear. Or is there another RELIABLE, existing energy source out there?
