EVERYDAY SCIENCE

Detailed explanation-1: -A renewable resource is a resource of which there is an endless supply because it can be replenished. The sun, the wind, and geothermal heat are considered inexhaustible and therefore are examples of renewable resources. Water is also considered a renewable natural resource, as long as there is precipitation.

Detailed explanation-2: -A resource is renewable if it is remade by natural processes at the same rate that humans use it up. Sunlight and wind are renewable resources because they will not be used up (Figure below).

Detailed explanation-3: -What are renewable resources? Renewable resources can be replaced within a lifetime. Some renewable resources, such as plants and animals, provide food for humans. Other renewable resources, such as sunlight and wind, provide energy.

Detailed explanation-4: -Renewable resources include solar energy, wind, falling water, the heat of the earth (geothermal), plant materials (biomass), waves, ocean currents, temperature differences in the oceans and the energy of the tides.

Detailed explanation-5: -Examples of renewable energy sources include wind power, solar power, bioenergy (organic matter burned as a fuel) and hydroelectric, including tidal energy.
