Using Renewable Energy Resources

What is renewable energy? Renewable energy is energy which is derived from natural resources such as sunlight, wind, rain, and geothermal heat, which are renewable and naturally replenished. One of the primary goals of green technology is to shift our focus on these renewable energy sources, so as to curb the pollution and protect our planet.

Here are some renewable energy resources:

Wind power
Running wind turbines to produce energy have become the most common for commercial use. Power output depends on the wind speed and increases dramatically with increase in the speed of the winds. Preferred locations for wind farms are areas where winds are stronger and more constant, such as offshore and high altitude sites. Following these renewable energy solutions is one of the main aims of green technology.

Hydropower
Another of the popular renewable energy sources is the energy in water, which can be harnessed and used. Water can produce considerable amounts of energy. Some forms of water energy are large-scale hydroelectric dams, run-of-the-river hydroelectricity and ocean energy.

Solar energy
Derived from the sun, as solar radiation, this is fast turning as one of the most important renewable energy resources, especially in countries with plenty of sun the whole year round. Some examples of its use are solar hot water, solar cooking, and heat for industrial purposes.

Biomass
Plant material or biomass is a renewable energy source because it contains energy primarily derived from the sun. When the plants are burnt, they liberate the sun's energy they contain. As long as biomass is produced sustainably, these can prove to be renewable energy solutions and can last indefinitely.
