Renewable energy is enhancing as an important issue day by day in today’s world. The main reason behind this is a rise in the cost of fossil fuels and the hazard of Environment change. It has been improving the efficiency as well as lessen the price. Regarding various types of renewable energy resources which include Biomass, Solar, Tidal, and Wind, etc.
Biomass:
Biomass refers to the use of organic materials and converting into other energy forms. Meanwhile, the forms of biomass is useful for so many years which include burning wood. Even there are new methods which don’t produce the Carbon Dioxide in the environment. Biofuels are produced by the biological process whereas the Fossil fuels are produced by a geological process. So the biofuels are becoming best alternatives to oil and gas as these fossil fuels pollute the climate, and also these are non-renewable.
Solar:
Solar power is one of the most popular, and fastest-increasing source of alternative energy. Here, the process involves solar cells that are made from slices of crystalline silicon and they rely on the PhotoVoltaic effect to absorb photons for converting them into electrons. Meanwhile, the solar-thermal power which is another form of solar power depends on the mirrors or lenses to intensify a large area of sunlight.
Photovoltaic power was used only for small to medium-sized operations ranging from the solar power devices to domestic arrays initially. Later, solar power plants have been concentrated more on the commercial array since 1980’s. The major factors such as an increase in solar cell efficiency and lessen prices are accomplishing the solar power competitive with conventional sources of power such as coal and fossil fuels.
Tidal:
Tidal power is treated as the best potential source of renewable energy as the tides are predictable and steady. Such as windmills, tide mills have been used since so many days where the inflow water was stored in the large ponds. The tides produced in the pond turns the waterwheels that generate the mechanical power to mill grain. Tide mills are constructed nearby coastlines and rivers to utilize the more water to produce the mechanical power.
Wind:
Wind power is considered to be the best alternative to the conventional energy sources, and it has widely used since years. Like tide mills, windmills are also being used these days with the installation of wind turbines. Whenever the wind flows, the shaft of the turbines will be rotated and produces the electricity to be used.
The energy produced from one medium-sized turbine can power a single home or business farm. Compared to other sources of renewable energy, wind power is very reliable, steady, and even it supplies the power as per the demand during peak hours also. Initially, the cost of construction of tide mills was high but the recent improvements made it very less.
