Home Energy Rating System (HERS) – A nationally recognized energy rating program that gives builders, mortgage lenders, secondary lending markets, homeowners, sellers, and buyers an evaluation of how the energy efficiency of one home compares with others. The home receives a rating from 1 to 100, depending on its relative efficiency. The score is than equated to a Star rating system. One star (Extremely Poor) five Stars (Extremely Efficient).

Hybrid Renewable Energy System – A renewable energy system that includes two different types of renewable energy technologies that produce the same type of energy, for e.g., a wind turbine and a solar photovoltaic array combined to meet a power demand.

Hybrid Electric Vehicles (HEVs): Combine the internal combustion engine of a conventional vehicle with the battery and electric motor of an electric vehicle, resulting in twice the fuel economy of conventional vehicles. This combination offers the extended range and rapid refueling that consumers expect from a conventional vehicle, with a significant portion of the energy and environmental benefits of an electric vehicle. The practical benefits of HEVs include improved fuel economy and lower emissions compared to conventional vehicles. The inherent flexibility of HEVs will allow them to be used in a wide range of applications, from personal transportation to commercial hauling.

Hydrothermal- Pertains to hot water or the action of heated water, often considered heated by magma or in association with magma.
