The high cost of storing electricity has prevented conversion and integration of renewable energies in the United States. However, a recent Stanford study and demonstration in Canada prove that storing electricity understand is not only more efficient, but also less costly than traditional batteries.
Marc Jacobson, Stanford professor of civil and environmental engineering, and Mark Delucchi of University of California, Berkeley have been studying computer-generated models to determine what technology is needed for America to be 100% electric. Their proposed system relies upon storing excess wind, solar, and water electricity underground in the forms of hot water, ice, and even hydrogen.
The Drake Landing Solar Community near Calgary, Canada, uses these principles to heat 52 homes in the winter from hot water stored 120 feet underground.
