Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in , and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around in Italy, Austria, and Switzerland. The technique rapidly expanded during the 1960s to 1980s ,. One megawatt-hour (MWh) is equivalent to 1,000 kilowatt-hours (kWh), 4. Therefore, if a system operates continuously for one hour under that capacity, it stores 1,000 kWh, and 5. Various factors, including system efficiency and technology, can influence these figures significantly. [pdf]
