Gordon W. Tomb Discusses the Costs of Green Energy Mandates on the Powering America Podcast
In a recent episode of the Powering America Podcast, Gordon W. Tomb, a senior fellow at the Commonwealth Foundation, discussed the impact of green energy mandates on electricity prices and reliability. The episode, hosted by Bryan Hyde, aired on [insert date], and highlighted concerns regarding the effectiveness and economic viability of renewable energy sources.
Tomb, who has extensive experience in the energy sector, explained that green energy mandates require electricity providers to source a certain percentage of their energy from renewable sources. In Pennsylvania, for example, the Alternative Energy Portfolio Standards mandate that at least 18% of electricity must come from renewable sources, including solar and wind energy. According to Tomb, these mandates have resulted in significant costs for consumers, with Pennsylvania residents facing a projected $700 million in expenses by 2025.
"The purpose of this was to help these technologies develop," Tomb said, referring to the initial intentions behind the mandates. "But at this point, of all the electricity generated in Pennsylvania, only 4% comes from so-called renewable sources. After 20 years and billions of dollars, what is the point?"
Tomb criticized the political motivations behind the continuation of these mandates, suggesting that they are often supported by politicians seeking donations from environmental groups. However, he noted a growing pushback against these policies due to rising electricity prices and concerns about reliability. He pointed to recent actions by politicians like Massachusetts Governor Maura Healey, who has shifted her stance on energy policy in response to high electricity costs.
Despite the intentions of green energy initiatives, Tomb argued that the costs have outweighed the benefits. "It's totally irrational," he said, emphasizing that many politicians are beginning to recognize the need for a more pragmatic approach to energy policy.
Tomb also addressed the reliability of various energy sources, stating that fossil fuels, particularly coal and natural gas, remain the most effective means of generating electricity. He expressed concern about the lack of political leadership to support the development of these resources, as well as nuclear power, which he believes has significant potential.
"Nuclear energy is a wonderful source of energy," Tomb said, recalling his own experiences working at the Three Mile Island plant. He highlighted the cleanliness and efficiency of nuclear power compared to fossil fuels and renewables.
As the conversation shifted to the role of data centers in the energy landscape, Tomb noted that while they require reliable energy, blaming them for high energy prices is misguided. He attributed the rising costs to poor public policy rather than the energy demands of data centers.
Tomb concluded by advocating for a rational approach to energy policy that considers the benefits and costs of all energy sources. He emphasized the importance of allowing experts to make informed decisions about energy generation, which he believes should include a combination of fossil fuels and nuclear power.
The discussion underscored the complexities of energy policy and the challenges associated with transitioning to renewable sources. As states like Pennsylvania continue to grapple with the implications of green energy mandates, the debate over the best path forward for affordable and reliable electricity remains a pressing issue.

Q&A: The Net-Zero Illusion: Gordon Tomb on Green Mandates and the Grid
Powering America Podcast: The Net-Zero Illusion
Q: Who is Gordon W. Tomb?
A: Gordon W. Tomb is a Senior Fellow at The Commonwealth Foundation, a free market think tank based in Pennsylvania. He has a background in energy, having worked as a newspaper reporter, in the nuclear power and electric utility industry, and as a management consultant in the oil and gas sector.
Q: What are green energy mandates? Can you provide an example?
A: Green energy mandates require consumers to purchase a certain percentage of energy from renewable sources, such as solar and wind. In Pennsylvania, the Alternative Energy Portfolio Standards mandate that electricity sellers provide at least 18% of their electricity from renewable sources.
Q: What has been the financial impact of these green energy mandates in Pennsylvania?
A: The green energy mandate in Pennsylvania has cost electricity customers approximately $700 million in 2025 alone, totaling about $3 billion over the life of the program. Despite this investment, only 4% of electricity generated in Pennsylvania comes from renewable sources.
Q: Is there political pushback against these green energy mandates?
A: Yes, there has been increasing pushback against green energy mandates, primarily due to rising electricity costs and concerns about electricity shortages. Some politicians, including those from traditionally supportive parties, are beginning to question the effectiveness of these programs.
Q: What are the best fuels for generating electricity today?
A: The best fuels for generating electricity currently are fossil fuels, particularly coal and natural gas, along with nuclear power. The U.S. has about 100 nuclear plants, but there is potential for more development in this area.
Q: Why hasn't political leadership shifted to support more reliable energy sources?
A: Political leadership has been slow to adapt due to entrenched beliefs in green energy and the influence of environmental groups. There is a gradual realization that effective energy policies must prioritize reliable and affordable energy sources.
Q: How do data centers impact energy needs?
A: Data centers require reliable and affordable energy to operate efficiently. However, some politicians blame data centers for high energy prices, despite the fact that many large data centers have not yet been built.
Q: What are the limitations of wind and solar energy?
A: Wind and solar energy have lower power density ratios compared to fossil fuels and nuclear energy. For instance, wind and solar produce about 3.5 units of energy for every unit invested, while coal produces 10 to 1, and nuclear can produce up to 100 to 1. Additionally, wind and solar require significantly more land and resources.
Q: What advancements are being made in nuclear technology?
A: Advances in nuclear technology, such as small modular reactors, hold promise for providing reliable energy. Nuclear power is seen as a clean and efficient energy source, with significant potential for growth.
Q: What are the implications of Governor Shapiro's energy proposals in Pennsylvania?
A: Governor Shapiro's proposals could increase the state's reliance on green energy, potentially leading to a $155 billion increase in electricity bills over ten years, effectively doubling household electricity costs. There is skepticism about the feasibility of these proposals.
Q: What direction should policymakers take regarding energy sources?
A: Policymakers should adopt rational, clear-headed thinking that recognizes the benefits and costs of all energy sources. A balanced approach combining fossil fuels and nuclear power is recommended for effective energy policy.
Q: What does Gordon W. Tomb hope for in energy policy?
A: Tomb hopes for policies guided by rational thinking that allow experts to make informed decisions about the best energy sources, emphasizing a combination of fossil fuels and nuclear power.
Key takeaways
- “The stated purpose for this particular program, which was initiated in 2004, more than 20 years ago, was to give these energy sources a foothold, a kind of a boost so that they could develop and gain market share.”
- “At this point, of all the electricity generated in Pennsylvania, 4% comes from so-called renewable sources. After 20 years, and billions of dollars. What is the point?”
- “It's totally irrational. And as I mentioned, people are starting to back away from it.”
- “The energy breakthrough that will take the world into the 21st century will almost certainly be political, not technological.”
- “Wind and solar will take 10 times and more, in some cases, 10 times the land for to produce the same amount of energy that traditional sources take.”
