Private Sector Outpacing Policy in Transition to Renewable Energy: A Closer Look

Utilities in the United States have set an ambitious goal to transition to 100% renewable electricity by 2060. While state mandates have played a part in this transition, it is the utilities themselves that are leading the way. The rapid progress in the private sector is driven by factors such as technological advancements, decreasing costs, the rise of natural gas as a replacement for coal, and the increasing adoption of renewables as a substitute for fossil fuels. While policy is an important lever, it is not the sole driving force behind this monumental shift.

Grace Kroeger, an honors thesis student in Environmental Studies at CU Boulder, embarked on an assessment inspired by her internship at a consulting firm. She wanted to examine the actions taken by the entities responsible for the energy that we all use and consume. Kroeger, along with co-author Matthew Burgess, a CIRES fellow and CU Boulder assistant professor, compared state renewable energy targets with utilities’ own goals. By analyzing 30 years of data, they sought to understand the extent to which utilities are aligning with renewable energy standards driven by state-level policies.

Renewable Portfolio Standards (RPS) and Clean Energy Standards (CES) have been crucial in mandating changes across states, but their stringency varies. Some states have aggressive policies, while others have more manageable goals or no standards at all. In addition to state-level policies, utilities have set their own goals, often published online. For instance, Xcel Energy aims to achieve 100% carbon-free electricity by 2050. By combining data, the authors projected the timeline for utilities to fully decarbonize. Surprisingly, they found that the private sector is outpacing policy in achieving decarbonization targets.

Surprising Findings and Cross-State Differences

The study uncovered two key findings that challenge common perceptions. Firstly, utilities are on track to meet or exceed the goals set by states with renewable energy policies and mandates. The authors project that the electric grid will be 100% decarbonized by 2060, provided utilities stay committed to their plans. Moreover, when including nuclear energy in renewable portfolios, decarbonization may occur even earlier, possibly by 2050. The second surprising finding is that utilities plan to decarbonize across the board, even in states without renewable policies or goals, exemplified by Southern Company’s commitment to decarbonization despite operating in states without portfolio standards.

While there are differences between blue and red states, with blue states typically having stricter renewable energy goals and policies, most states, regardless of their political affiliation, are making progress towards decarbonization. The authors emphasized that their findings are based on utilities’ stated plans, which aren’t guaranteed. Nevertheless, historical data suggests that utilities have already surpassed their expectations by transitioning to renewables and reducing reliance on fossil fuels at a faster pace than initially planned.

The Challenge to Meet the Biden Administration’s Goal

Despite the positive trajectory, both states and utilities are falling short of the ambitious goal set by the Biden Administration: to eliminate fossil fuels from the U.S. energy sector by 2035. The announcement of this goal did not come with accompanying policies or mandates to facilitate the transition. While progress is being made in the private sector, there is a need for increased efforts to ensure alignment with the administration’s objective.

The transition to renewable energy is being driven by the private sector, with utilities taking the lead. Technological advancements, cost reductions, and changing market dynamics have propelled utilities to surpass state-level goals and make significant strides towards decarbonization. Despite the gaps between blue and red states, the majority of utilities are on a path towards achieving their decarbonization objectives. However, there is still work to be done to meet the ambitious targets set by the Biden Administration. With ongoing advancements and an increased focus on sustainable practices, the private sector holds the key to a greener and more sustainable energy future.
