Renewable Resources :-
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. The rising and falling of ocean tides is another example of a resource in unlimited supply.
A maintainable asset is an asset that is utilized as a part of a way that addresses the issues of the present without shielding future ages from addressing their requirements.
Alternative Energy Sources
A nonrenewable resource is one that cannot be replaced as easily as it is consumed. Fossil fuels are an example of nonrenewable resources.
The following are examples of sustainable alternative energy resources:
Solar power, which uses solar cells to turn sunlight into electricity . The electricity can be used to power anything that uses normal coal-generated electricity.
Wind power, which uses windmills to transform wind energy into electricity. It is used for less than 1% of the world’s energy needs. But wind energy is growing fast. Every year, 30% more wind energy is used to create electricity.
Hydropower , which uses the energy of moving water to turn turbines (similar to windmills) or water wheels, that create electricity. This form of energy produces no waste or pollution. It is a renewable resource.
Geothermal power, which uses the natural flow of heat from the Earth’s core to produce steam. This steam is used to turn turbines which create electricity.
Biomass is the mass of biological organisms. It is usually used to describe the amount of organic matter in a trophic level of an ecosystem.
Renewable resources can be replaced by natural processes as quickly as they are used.
Alternative energy sources include wind power, solar power, hydropower, and geothermal power.
