Warming U.S. Cities Face Higher Cooling Demand and Energy Bills
Analysis of cooling degree days (CDD) shows that 97% of 241 major U.S. cities experienced increased cooling demand since 1970, with an average increase of 37%. This trend, combined with a 31% rise in residential electricity prices between 2020 and 2025, increases the financial burden on households, particularly low-income families. In 2020, the ten states with the highest cooling costs saw average household expenditures between $378 in Hawaii and $712 in Arizona. Future projections suggest U.S. household cooling demand will rise 43% by 2050. The report also highlights systemic risks, including electricity grid strain, increased carbon emissions from fossil-fuel-reliant cooling, and the urban heat island effect caused by waste heat from air conditioners.

Grid-Scale Virtual Power Plants are Here. Have Utilities Noticed?
Virtual power plants (VPPs) are reaching scales that rival traditional power plants, with some programs exceeding 1 GW. Despite this, the document finds that utilities often fail to properly model VPPs in integrated resource plans (IRPs) and distribution system plans (DSPs), frequently treating them as fixed load adjustments rather than selectable resources. This planning gap leads to an underestimation of VPP value and a risk of redundant infrastructure investment. The author recommends that regulators and utilities develop detailed resource attributes for VPPs, allow for their growth in models, and evaluate their benefits across both bulk power and distribution systems.

The Geothermal Supply Chain Is America’s to Gain — or Lose
The United States is well-positioned to lead the next-generation geothermal supply chain due to significant overlaps with the oil and gas industry, though gaps remain in superhot rock (SHR) compatible rigs and power conversion turbomachinery. While investment in the sector grew from $22 million in 2018 to $2.2 billion in 2025, the report warns that equipment supply chains could become a bottleneck for national-scale adoption. Developing a domestic supply chain could create over 100,000 jobs in wellfield and plant operations and catalyze manufacturing growth in regions like Louisiana, Texas, Oklahoma, Georgia, New York, North Carolina, and South Carolina. To secure this advantage, the report recommends expanding the 45X advanced manufacturing production tax credit to geothermal and improving data on equipment capacity and production costs.

Beyond hazards and sectors: governing systemic climate risks
The report identifies a recurring 'implementation gap' where adaptation policies increasingly use the language of systemic risk—interconnected hazards, cascading impacts, and deep uncertainty—but continue to operate through hazard- and sector-based routines. Through comparative analysis of the EU, ASEAN, and the US, it finds that mandates, funding, and monitoring systems remain fragmented, often ignoring policy trade-offs and distributional inequities. It concludes by proposing a framework based on systemic risk framing, policy interlinkages, and deep uncertainty management to help decision-makers stress-test investments and avoid maladaptation.

Are electric heat pumps cheaper than gas furnaces?
The document argues that heat pumps are a cost-effective alternative to gas heating due to their superior energy efficiency, which allows them to overcome higher electricity costs. In the residential sector, heat pumps have outsold gas furnaces for four consecutive years. In the industrial sector, they are particularly viable for low-temperature processes (under 200°C), with the potential to increase U.S. GDP by over $42 billion by 2030. The briefing concludes that other alternatives, such as hydrogen and renewable natural gas, are less scalable and more expensive than heat pumps.

Lower Bills, Better Grids: Heat Pump Benefits for Electric Resistance-Heated Homes
Upgrading the millions of US homes relying on electric resistance heating to air-source heat pumps (ASHPs) and heat pump water heaters (HPWHs) offers significant benefits for affordability, grid reliability, and climate goals. For single-family homes, these upgrades can save households an average of $1,530 annually and reduce total carbon pollution by approximately 40%. At scale, such transitions could reduce US residential summer peak demand by 11 GW and winter peak demand by 51 GW. The report advocates for updating building energy codes to discourage electric resistance in new construction and retrofits, setting specific replacement targets, and implementing midstream incentive programs and on-bill financing to overcome up-front cost barriers.
