Many solar and wind facilities use lead batteries to regulate variability and increase reliability to deliver on-demand power. They store excess energy when demand is low and release it when demand is high, to ensure a steady supply of energy to millions of homes.
Lead batteries are also deployed in remote small-scale hydro-electric systems to help provide essential, clean energy for communications, refrigeration and more to many of the 1 billion people that lack access to a power grid.
Lead batteries are one of the most environmentally sustainable of all battery technologies, which makes them an ideal sustainability partner for solar and wind power. In 2016, more than half of electricity generation capacity added to the U.S. grid came from renewable resources, and 60 percent of all utility-scale generation capacity additions were from wind and solar resources. Lead batteries help to make this growth possible and are vital to ensure continued growth of sustainable energy sources.
Lead batteries are also critical in helping to close the gap between those who have access to electricity and those who do not, especially in remote geographic areas.
Nearly 25 percent of the populations of all developing countries have no access to electricity. Lead batteries can store and optimize energy from renewable energy sources when there is no access to a power grid.
