| Hybrid | A hybrid ballast has a magnetic core-and-coil transformer and an electronic switch for the electrode-heating circuit. Like a magnetic ballast, a hybrid unit operates at line power frequencyÑ60 Hz in North America, for example. These types of ballasts, which are also referred to as Òcathode-disconnect ballastsÓ, disconnect the electrode-heating circuit after they start the lamps. | View | None |
| Hybrid | Hybrid system | View | None |
| Hybrid | A Telephone or component of a Telephone system that has the ability to ultimately convert sound into both analog waveforms for transmission through the PSTN and Internet Protocol data packets for transmission through an Ethernet connection. | View | None |
| Hydrokinetic | Systems that use the natural flow of water rather than damming or diverting flow through conventional turbines. Designs may include pistons, turbines, and pumps. Systems are typically installed in rivers and ocean areas with strong tidal flows. | View | None |
| Hydronic loop make up | View | None | |
| Hydroponic loop | Hydroponic loop fixture | View | None |
| Hydropower | Hydropower projects capture the kinetic energy of moving water to produce electricity with the construction of dams. While hydropower is renewable and produces relatively few GHG emissions, hydropower projects can have other impacts on the environment, such as obstructing fish passage and altering land resources by impounding excessive nutrients | View | None |

| Hydrothermal | A hydrothermal resource is a geothermal resource that often involves fluid, heat, and permeability for electricity generation. These geothermal systems can occur in diverse geologic settings, sometimes without clear surface manifestations of the underlying resource. Low-temperature geothermal energy is defined as heat obtained from the geothermal fluid in the ground at temperatures of 300¡F (150¡C) or less. Low-temperature resources can be harnessed to generate electricity using binary cycle electricity generating technology. | View | None |
