A renewable supply is any energy or supply that is replenished by a natural process at a rate that equal to or greater than the speed at which it is used. Due to the impending global energy crisis brought about by over consumption of fossil fuels, humans must turn to renewable resources as a means for alternative energy. Some of these resources include geothermal power, wind power, solar power and hydropower.
Renewable resources, if managed properly can improve the way we consume energy, while improving our quality of life. One example of this type of energy is geothermal power. Geothermal power is energy that is stored beneath the earth’s surface, which can be used to heat buildings, grow plants in greenhouses, melt snow in winter, heat water for fish farming and the steam from this energy source can also be used in dry steam plants to turn turbines.
Solar power is one of the renewable resources that has been used by humans for thousands of years. It can be used for heat, providing light for buildings, generating heat for water and cooking, and it can be used for generating electricity.
Hydropower, which is derived from the force of moving water, has been harnessed for centuries. Water running over a waterwheel can be used to operate machinery, hydroelectric dams are able to harness the incredible force of flowing water in order to generate electricity; and irrigation is a great way to divert water and spread it over vast spaces where water generally doesn’t exist in order to grow crops as well as provide potable drinking water.
