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,.

Solar inverters may be classified into four broad types: 1., used in where the inverter draws its DC energy from batteries charged by photovoltaic arrays. Many stand-alone inverters also incorporate integral to replenish the battery from an AC source when available. Normally, these do not interface in any way with the utility gri.

According to the IEA the electricity use (gross production + imports – exports – transmission/distribution losses) in Switzerland was in 2004 60.6 TWh, (2007) 61.6 TWh and (2008) 63.5 TWh. In 2008 Switzerland consumed electricity per inhabitant 122% compared to the European Union 15 average (9,052 / EU15: 7,409 electricity use per inhabitant 2008, kWh/person) and 133% compared to the United Kingdom (2008: UK 372.19 TWh per 59.9milj. person, and Switzerland 63,53 TWh per 7,71 milj.person).
