LET THE SUN IN: CLEAN ENERGY IS THE CHEAPEST WAY TO MEET RISING DEMAND

The report argues that meeting U.S. electricity demand growth through 2030 with a clean energy portfolio is more affordable and reliable than a fossil-fuel-heavy approach. Modeling shows that a clean energy scenario could save consumers $5.1 billion annually by 2030 and significantly reduce risks associated with volatile fuel prices and extreme weather. The analysis emphasizes the role of solar, wind, battery storage, and demand-side flexibility in reducing system costs and carbon emissions while maintaining grid resilience.

• Meeting U.S. electricity demand growth primarily with fossil fuels is projected to cost $29.7 billion per year by 2030, whereas an accelerated clean energy approach could reduce this cost by 17 percent, saving consumers $5.1 billion annually.
• Clean energy provides a hedge against fossil fuel price volatility. In a high-fossil scenario, a price spike in coal and gas would increase electricity costs by $40.5 billion per year; a clean energy pathway would reduce this spike by $8.4 billion, resulting in total savings of $13.5 billion compared to the fossil-heavy plan.
• A clean energy strategy remains cost-effective even if demand growth is lower than expected. If only 33 percent of the anticipated demand growth materializes, a clean energy system would still save $2.6 billion per year compared to a high-fossil system.
• The U.S. can maintain a reliable and resilient grid while meeting growing demand with clean energy, including under challenging weather conditions. The clean scenario reduces fossil fuel generation by over 32 percent, from 2,949 TWh in the high fossil case to 2,000 TWh.
• Demand-side solutions, including energy efficiency and demand flexibility, are critical for reducing costs. In the clean scenario, demand response reduces peak demand by 26 GW and energy efficiency reduces it by 33 GW, with efficiency lowering overall generation by 186 TWh by 2030.
• The clean energy pathway significantly reduces environmental and health impacts. It is projected to lower CO2 emissions from 2025 levels by 25 percent by 2030, whereas the high fossil scenario would result in emissions 22 percent higher than 2025 levels.
• In the PJM region, which faces extreme demand growth from data centers, a clean energy scenario would involve building 53 GW of solar, 19 GW of wind, 9 GW of batteries, and 2 GW of new gas by 2030, while retiring 26 GW of fossil capacity.
