Green Energy, this is the common term that we are listening to these days as there are many awareness programs that are concentrating on green energy. The main intention of these programs is to make us aware of green energy and different ways to reduce the dependence on fossil fuels.
Green energy emerges from different natural sources like wind, sunlight, plants, light and much more. All these resources are renewable and can show a smaller impact on the environment than compared with fossil fuels. It utilizes the resources that are available in this world such that it replaces fossil fuels in all major areas such as electricity and water. There are different types of green energy. Here are few important types of green energy:
• Solar Energy: This is the most common form of energy that relies on sunlight. The energy from sunlight can be collected and be used in different ways. Electricity can be generated from the captured sunlight. Though the solar energy has higher potential, but it was left behind as fossil fuels were made available at an affordable price than solar energy. Since there is a shortage of fossil fuels, it made us look forward to this option again. This is definitely the best option as compared to the fossil fuels with smoke left into air, thus polluting the environment.
• Wind power: This type of energy has been used since many years. It can generate energy sources that can replace the use of fossil fuel for generating electricity. Wind power is the major source of energy that has the capacity to supply more than the current energy consumption worldwide.
• Hydroelectric Energy: This also called as hydropower that is generated with the water cycle. This is not that much renewable as compared to other sources. It becomes more expensive to make the hydroelectric energy renewable.
• GeoThermal Power: It is energy from Earth and the main source of energy is heat, that contained inside the earth. This is more renewable as it is available in abundance and can definitely replace the existing fuel usage. It can reduce the dependence on fossil fuel and can be utilized anywhere, thus resulting in reduced energy costs. Though it is available in abundance, there are several problems that are preventing us from the usage of this Geothermal energy.
Apart from these, there are several other forms of renewable energy that are used to generate electricity at minimal cost compared to expensive fuels.
