Reagan Paul, a public official and commentator on energy policy, used her Twitter account on May 27 and 28, 2026, to address issues related to climate modeling and renewable energy generation in New England. In her posts, she raised questions about the relevance of the United Nations’ shift away from the RCP 8.5 emissions scenario and highlighted concerns over the region’s reliance on solar power.
On May 27, Paul questioned the impact of changes in global climate modeling on local energy policies. She wrote, “What does the UN retiring RCP 8.5, admitting its ‘worst-case climate scenario’ was wrong, have to do with Maine and our aggressive renewable energy push? Turns out A LOT. Let me explain. RCP 8.5 was the famous high-emissions pathway that projected extremely large warming by 2100” (May 27, 2026).
Later that day, she provided real-time data about New England’s electricity grid performance: “Right now at 6:48 pm on May 27th, 2026: ALL of the solar panels in ALL of New England are contributing only 1% of the power to our grid. Or in other words — only 167 MW of the current system demand of 16,757 MW. Wind: 5.2%. Refuse: 1.7%. Wood: 1.0%. Landfill gas: 0.2%” (May 27, 2026).
On May 28, Paul referenced a statement from a Connecticut official while discussing proposed legislation regarding renewable energy project oversight: “This is a statement from Graham Stevens, chief of Connecticut’s Department of Energy and Environmental Protections (DEEP), Bureau of Water Protection and Land Reuse. This is why I introduced LD 451, ‘An Act to Require Testing of Solar and Wind Energy Developments for'” (May 28, 2026).
The RCP (Representative Concentration Pathways) scenarios were developed as part of climate modeling efforts used by organizations such as the Intergovernmental Panel on Climate Change (IPCC). The RCP8.5 pathway assumed very high greenhouse gas emissions but has been criticized for representing an unlikely trajectory given recent global policy shifts toward lower emissions.
New England has seen significant investment in renewable energy sources like solar and wind; however, their variable output remains a topic of debate among policymakers concerned about reliability during peak demand periods.
Paul’s reference to LD 451 highlights ongoing legislative efforts aimed at increasing scrutiny over environmental impacts associated with renewable infrastructure projects.
