DENDROLOGY

Detailed explanation-1: -Renewable resources are those resources that continue to exist despite being consumed or can replenish themselves over a period of time even as they are used. They include the sun, wind, water, geothermal, and biomass. The disadvantage of renewable resources is that they may not be available for use when needed.

Detailed explanation-2: -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. This includes wood, sewage, and ethanol (which comes from corn or other plants).

Detailed explanation-3: -Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being replenished.

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: -Renewable energy refers to the provision of energy via renewable resources which are naturally replenished as fast as they are being used. Examples are sunlight, wind, biomass, rain, tides, waves and geothermal heat.
