Homeowners relying on traditional gas-powered generators may want to reconsider. Experts at EnergySage are urging a shift toward next-generation home backup batteries, which they say offer major advantages in cost, safety, and environmental impact.
While backup batteries can cost more to install upfront, EnergySage says the long-term savings are substantial. Over 20 years, the cost of operating a gas generator could reach $78,000, compared to just $39,000 for a battery system.
One of the biggest cost-saving benefits comes from how batteries are refueled. Unlike gas generators, which need regular fuel purchases, batteries can recharge using solar power or low-cost electricity from the grid during off-peak hours. This setup not only reduces fuel expenses but can also cut monthly utility bills by supplying power during high-rate periods.
Even without solar panels, batteries help keep energy costs down and provide resilience during power outages. But when paired with solar, they become even more powerful. During the day, solar panels generate electricity, which the batteries store for use at night or during blackouts.
To help homeowners make the switch, EnergySage offers a free online tool that connects users with local installers. These professionals can provide customized quotes and explain how to take advantage of rebates and incentives—sometimes saving up to $10,000 on installation costs. An interactive map on the EnergySage site also shows average prices and available state incentives.
However, federal tax credits and rebates that make these systems more affordable may not last forever. Experts advise acting soon, as some incentives are facing potential repeal in Congress.
Beyond financial savings, switching to a battery-backed solar system helps cut pollution. Most of the U.S. power grid still runs on fossil fuels like coal and gas. Using less grid electricity means releasing less carbon dioxide into the atmosphere—a key step in fighting climate change. Reducing emissions can also help slow rising sea levels, prevent ocean acidification, and reduce the risk of extreme weather.
For homeowners looking to save money and support a cleaner energy future, battery backups offer a smart alternative to old gas-powered generators.
