is energy that is produced from this material. Recall that fossil fuels, too, come from living things. However, unlike energy from fossil fuels, biomass energy is renewable.

Liquid fuels from biomass sources, known as biofuels

Biopower Electricity that is generated by the combustion of biomass is called biopower.

Deep beneath the surface of Earth, high pressure combined with the breakdown of radioactive elements produces heat. This heat is geothermal energy

ground source heat pump

A ground source heat pump takes advantage of the fact that the temperature of soil a few feet under- ground stays about the same all year, even though the air temperature changes with the seasons

In hydropower, or hydroelectric power, we use the kinetic energy of moving water to turn turbines and generate electricity

The term tidal energy refers to using the movement of tidal water to generate electricity

ocean thermal energy conservation

is a process that converts the thermal energy in ocean water to electrical energy that people can use.

passive solar heating

Passive solar heating involves designing a building to collect, store, and distribute the sun's energy naturally

active solar heating system uses technology to collect, move, and store heat derived from the sun

flat-plate solar collector

A flat-plate solar collector generally consists of a black, heat-absorbing metal plate in a flat box with a glass cover.

photovoltaic (PV) cell

In a photovoltaic (PV) cell, solar energy is converted directly into electricity. Photovoltaic cells contain two plates

concentrating solar power (CSP)

In this CSP facility in Spain, hundreds of mirrors focus sunlight toward the power tower to generate electricity

A wind turbine is a device that converts the wind's kinetic energy, or energy of motion, into electrical energy

Wind turbines are most often built in groups called wind farms

In electrolysis, water molecules are broken down into oxygen gas (O2) and hydrogen gas (H2) by an electric current that runs through the water. This reaction can be expressed by the following chemical equation: 2 H2O →→ 2 H2+02 Electrolysis produces

Hydrogen gas can be used to produce electricity
