This document defines key vocabulary terms related to energy resources. It describes nonrenewable resources like fossil fuels that are depleted once used, and renewable resources like solar and wind energy that can be replenished. It also discusses energy conservation, inexhaustible resources, and different types of energy resources including fossil fuels, biomass, geothermal, hydroelectric, nuclear, geothermal, hydropower, biomass, natural gas, alternative resources, solar energy, and biofuels.
