There are various energy sources, out there, that are renewable and above all, they are environment-friendly and make use of varied natural processes. Such energy sources offer an alternative cleaner energy source, assisting to nullify the effects of different types of pollution.
There is no doubt that such power generation methods can also be termed as renewable because they won’t be depleting any other source in order to create the energy. Below-mentioned 7 energy sources go to prove that we can significantly cut down our dependency rate on the fossil fuels.
There are two ways in which tidal power can be generated – barrage generation and stream generators. The power that you get to generate through the tidal generators are more environment-friendly, above all, they have less impact on the established ecosystems. Pretty much like a wind turbine, varied stream generators assist in rotating underwater. Despite the fact that it not widely used, it does possess the potential for future electricity generation.
Wave power can be defined as the transport of the energy via ocean surface waves and to seize that energy to useful work – water pumping, generation of electricity, and water desalination. Since the ocean waves direction cannot be predicted, it is quite difficult to harness the wave energy.
Photovoltaic (PV) solar power can be described as harnessing the energy of the sun in order to produce electricity. With the advancement in the field of technology, solar cells have also become quite advanced, flexible, and mobile, hence really coming handy in easy installation. The use of PVs is mainly done to power varied small & medium-sized applications. In recent years, solar installations have also increased considerably especially in the residential areas as governments are offering lucrative incentive programs to make green energy more economically feasible option. In addition, many cities across the globe are switching to more sustainable and energy resilient LED street lighting options powered by solar energy.
Using the wind turbines, wind energy is converted into a useful form including mechanical and electrical energy. Mainly providing electricity to the remote areas, large-scale wind farms are fastened to the local power transmission network along with small turbines. Varied residential units are entering production, they are powerful enough to power large appliances to entire house as per the sizes. As compared to others sources of energy, all those wind farms, installed on the agricultural land, have minimal environmental effects.
In the past, wind energy was being used to propel the sailing ships or gets converted into mechanical energy to pump the water or grinding grain, however, the key application of wind power is to generate electricity.
The main source of hydroelectricity is hydro power. Now, this means that the power is produced using gravitational force of the falling water. Without a doubt, it is one of the commonly used forms of renewable energy. A hydroelectric complex does not produce any direct waste. Mainly in the remote areas where there is no feasible source of energy, micro-hydro power or small-scale hydro are a quite popular alternative source of energy. The main advantage of hydro power systems is its hassle-free installation in the small rivers or streams.
Various large scale hydropower systems produce energy by using a dam or major water diversion. While most of the hydroelectric projects supply public electricity networks, some of them serve the industrial purposes as well.
The best thing about radiant energy is that it is also capable of doing all those wonders as standard electricity and that too at 1% of the cost. Making the most of this source of energy, there is a community in Switzerland (The Methernitha Community) having a total of six models of fuelless, independently running devices. Radiant energy of T. Henry Moray, magnifying transmitter of Nikola Tesla and EMA motor of Edwin Gray all run on radiant energy.
This form of natural energy can be easily collected directly from the environment or it can also be extracted from standard electricity using a method known as fractionation.
If you want to know one of the effective ways of extracting a renewable energy from the earth with the help of natural process, then it is geothermal energy. Performing on a small scale, it is capable of providing heat for the residential areas or talking about large scale, it can be used for producing energy via a geothermal power plant. Since ancient roman times, it has been used for bathing and space heating, however, in the modern times, it is better recognised for producing electricity.
There are various benefits of geothermal power including – environmentally friendly, cost effective, and above all, it is quite reliable as well. With technology that become extremely advanced, there has been a noticeable expansion in the range and size of practical resources mainly for direct applications such as home heating.
