Detailed explanation-1: -Renewable resources include biomass energy (such as ethanol), hydropower, geothermal power, wind energy, and solar energy. Biomass refers to organic material from plants or animals.
Detailed explanation-2: -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-3: -Renewable resources can be replaced as quickly as they are used. Renewable resources may also be so abundant that running out is impossible. The difference between non-renewable and renewable resources is like the difference between ordinary batteries and rechargeable ones.
Detailed explanation-4: -Renewable resources are natural resources that can be replaced in a relatively short period of time or are virtually limitless in supply. Renewable energy resources include wind, sunlight, moving water, biomass, and geothermal energy.
Detailed explanation-5: -Renewable resources can be replenished by natural processes as quickly as humans use them. Examples include sunlight and wind. They are in no danger of being used up (see Figure below). Metals and other minerals are renewable too.
