The explosive growth of artificial intelligence and cloud computing is reshaping U.S. electricity demand for the first time in a generation. Data centers are now among the largest and fastest-growing loads on the grid—and pairing digital infrastructure with solar, battery storage, and long-term PPAs is becoming a strategic clean energy investment.
A step change in demand
For years, U.S. electricity demand was essentially flat as efficiency gains offset growth. That era is over. U.S. power consumption set records in 2024 and 2025 and is forecast to keep climbing through 2027, with data centers accounting for roughly half of all projected load growth over the next five years. Analysts expect data-center power demand alone to more than double between 2025 and 2027. AI training clusters and hyperscale cloud facilities consume enormous, around-the-clock power, and utilities are scrambling to keep pace—nowhere more than in Texas (ERCOT) and the Mid-Atlantic (PJM), where growth is concentrated.
This creates both a challenge and an opportunity:
- Challenge: meeting new demand without increasing emissions
- Opportunity: pairing digital infrastructure with clean generation and storage
Why clean energy is the answer
Hyperscalers and enterprises have made public commitments to carbon-free energy. Meeting those commitments at scale requires:
- On-site and offsite solar to supply clean electrons
- Battery storage (BESS) to provide firm, 24/7 clean power
- Long-term PPAs that give both parties price certainty
Solar-plus-storage systems are particularly well suited to data center loads that require both high availability and clean power credentials. Solar and storage together made up roughly 90% of new U.S. grid capacity in early 2026—they are simply the fastest resources to deploy at the scale this demand requires. Hyperscalers are also pushing battery duration: recent colocated projects pair hundreds of megawatts of solar with eight-hour battery systems, well beyond the market's typical three-to-four-hour average.
The infrastructure investment case
Powering data centers with clean energy is not just an ESG story. It is a durable investment thesis. Demand is contracted, counterparties are creditworthy, and the assets are backed by one of the strongest secular growth trends in the economy.
Sunlight's position
Sunlight Energy Investments finances and develops solar, storage, and data-center infrastructure, pairing on-site generation and storage with the surging demand of AI and cloud. We see digital infrastructure as a defining opportunity for clean energy capital.
