There are countless energy sources that we have in modern era. Some of them are known as the non-renewable sources while others are renewable or green energy sources. The renewable energy sources are the ones that are decreasing with the time. For example, oil, gas, coal, etc. are some of the sources that we commonly use in modern era. However, with the time, their count is decreasing and eventually one day, may be after a century or two, they will retire. However, the green energy sources such as sun, wind, water are the ones that will exist till human life. Without sun or wind or water, the human life will become extinct. Therefore, these are the renewable energy sources that will not be depleted with the passage of time. Today, we are going to take a look at the types of renewable energy sources that are not common.
Uncommon renewable energy sources
While there are well known sources like wind, sun and water, many people do not know about the following:
- Hydrogen and Fuel Cells: It is a type of energy that is available to us in abundance. Moreover, when we will utilize it and convert it into other useful energy forms, the amount of pollution will also be highly less. We can use it as a fuel to power the vehicles and use water as the only product for its combustion. It will lower down the pollution level. Moreover, we can also use it in the fuel cells that can aid in powering the electrical machinery like motors. However, using it to as an energy source will require a good investment and you will have to consider multiple factors before its use. Therefore, the attention towards its use it not too high.
- Geothermal Power: Geothermal power is the energy that we get from the core of our planet. The depth of our planet, its core, it too hot and we can get a significant amount of heat energy from there. Considering this, there are certain points in our planet where this energy becomes too strong. The governments are making use of plants and utilize the energy coming from the core of earth in order to generate electricity. But there are certain problems with this method. The most significant of all is that there are only few locations where one can install a geothermal plant. However, by making its use, we can lower down the burden on other non-renewable energy sources.
- Hydrogen Fusion: It is a reaction that we can create with ease and obtain energy from it. However, in order to get a good amount of power, we have to do it on a large scale which will take some doing. However, scientists are trying to figure out how they can use it easily in so that they can reduce the load on other energy sources.
So, these are some uncommon yet usable types of renewable energy. The common types include wind, sun and water.
