What is renewable energy?
Renewable energy is energy produced from sources that do not deplete or can be replenished within a human’s timeframe, these include wind, solar, geothermal, biomass, and hydropower.
Renewable energy technology is a term used to describe all forms of technology that store up energy generated from renewable sources, and aslo helps to deliver energy produced by renewable energy technologies to its final consumer. Renewable energy tecnology uses natural resources such as sunlight, wind, tides and geothermal heat which are developed into solar power, hydroelectricity, biomass energy, and biofuels.
Agriculture which is also known as farming is the process of producing food, livestock and other beneficiary crop for human survival. Centuries ago farmers depend on human power, rain, sun light, wind and animal power which can also be renewable energy to grow their crops. In those days the world was greener and safer, before the discovery of fossil fuel followed by other machineries that can be use on farmland to make farming easier.
The aim was to be efficient in productivity when building machineries like generator, tractor, buldozer and many more which uses fossil fuel to operate on farm land. farmers uses this machines that are driven by fossil fuels in their day to day activities on the farm, truth be told it was efficient in productivity we all enjoy it but these machinery contribute to gas emissions, pollution which in turn causes disaster such as global warming.
To profer to solution to Such environmental damage, development of renewable resources such as solar, wind, biomass, tidal, geothermal, hydropower and biofuels has to be encouraged. These renewable energies have a huge significant potential for the agriculture industry, it has the capability of combining maximization of crop productivity, safer enviroment and maintenance of economic stability.
TYPES OF RENEWABLE ENERGY TECHNOLOLOGIES In the recent centuries, all attention are on Renewable Energy Technology since they consume primary energy resources that are not subject to depletion. Examples of renewable technologies include solar energy, wind energy, geothermal energy and biomass. We will discuss this technologies and their usefullness to agriculture below.
- SOLAR POWER
Solar power is sourced from the Sun with the help of photovoltaic (PV) through the use of solar cell, radiation from the sun is capable of producing heat and causing chemical reactions which makes production of solar electricity posssible. Solar power is inexhuastible, it widely use to dry various types of crops. Development of various solar devices began in the recent century, they include solar photovoltaic, solar cookers and solar dryer.
- WIND POWER
Wind energy is a form of solar energy which is produced by the movement of air relative to Earth’s surface and can be captured by using turbines and converting it into electricity. there are severval ways farmers benefit from wind energy, they can use the wind to generate their own power with the help of wind generator, this can help them to meet their energy need without stress. they can lease their land to wind developers or become wind power producer themselves. these power are more cheaper and convinient compare to disel generator.
- OCEAN ENERGY
Hydroelectric power comes from the natural flow of water, it uses the power of falling water in motion to generate electricity with the help of turbine turning the kinectic energy into a mechanical energy. There are different size of hydroelectic system which are the micro hydroelectric plant and large hydroelectic plant. The amount of electricity that can be produce depends on the volume of water passing through a turbine and the height from which the water falls from.
Bioenergy is a renewable energy sourced from organic matters that comes from recently living plants and organisms. Biogas plants decompose organic matters to release their stored energy such as biofuels and bioenergy.
