The Economist lists ice-based energy storage systems as among the technologies that can slash energy consumption without dampening economic growth.
"Storing off-peak energy as ice is particularly useful for air-cooling systems, one of the industrialised world’s biggest energy hogs," the Economist notes. "Air conditioning in commercial buildings accounts for about 5% of America’s electricity use. But in some parts of the country, on a hot day, the figure can reach 30%. Cooling systems from Calmac, a firm that used to make furnaces, store energy by cooling water mixed with antifreeze when power is cheap, and release it when it is needed, rather than relying on power-hungry compressors to cool the building during peak daytime hours."
