Ice storage air conditioning is a form of thermal energy storage in which cooling capacity is stored by freezing water and recovered later by melting the ice. In building applications, the storage can be charged when cooling demand or electricity prices are lower and discharged during periods of higher cooling demand,…

In air conditioning, an inverter compressor is a compressor that is operated with an inverter. In the hermetic type, it can either be a scroll or reciprocating compressor.

Geothermal energy in the United States was first used for electric power production in 1960. The Geysers in Sonoma and Lake counties, California was developed into what is now the largest geothermal steam electrical plant in the world, at 1,517 megawatts.

Hybrid vehicle drivetrains transmit power to the driving wheels for hybrid vehicles. A hybrid vehicle has multiple forms of motive power, and can come in many configurations.

Hybrid power are combinations between different technologies to produce power. In power engineering, the term 'hybrid' describes a combined power and energy storage system.

Load management, also known as demand-side management (DSM), is the process of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather than the power station output. This can be achieved by direct intervention of the utility in real time, by the use of…

A hybrid electric truck is a form of truck that uses hybrid electric vehicle (HEV) technology for propulsion, instead of using only a combustion engine. According to a report from Pike Research, the global market for hybrid medium- and heavy-duty trucks and buses will increase from 9,000 vehicles sold in 2010 to more…

Hybrid Synergy Drive system (HSD), also known as Toyota Hybrid System II, is the brand name of Toyota Motor Corporation for the hybrid car drive train technology used in vehicles with the Toyota and Lexus marques. First introduced on the Prius, the technology is an option on several other Toyota and Lexus vehicles…

A plug-in hybrid electric vehicle (PHEV) or plug-in hybrid vehicle (PHV) is a type of hybrid electric vehicle equipped with a battery that can be recharged via a power cable to an external electric power source, in addition to charging internally by its on-board internal combustion engine–powered generator. While…

This is a list of operational geothermal power stations with a current installed capacity of at least 10 MW. The Geysers in California, United States is the largest geothermal power station in the world, with a nameplate capacity of 1,590 MW and an annual generation of 6,516 GWh in 2018.
