Energy, of any kind, plays a vital role in our life. Without it, we might not have been able to survive. Thus, It is very important to preserve energy for the future generations. Hence, we all should use the renewable energy sources to cut the waste and save earth. The machines or plants which are required might be expensive to install, but they save huge amounts of money in long-term. Also, they do not pollute the environment.

Here are the 5 most renewable energy sources which we can implement:

1- Solar energy:

Sunlight is abundantly available on our planet. The amount of solar energy that can be conserved in one hour is enough for the entire planet for a whole year. Even if every household installs solar panels on their roof, it can cut down great amount of electricity bills. Solar energy is conserved during the day in batteries of solar panels which is enough to generate electricity the whole day even at night.

2- Wind turbines:

Wind turbines generate electricity by the movement of wind. The more the pressure of the wind, the greater the electricity will be generated. It is a clean way of generating electricity which does not cause pollution to the environment. The can be installed at larger scales or even indivisually at homes. Wind energy is more reliable than solar energy, and a large wind turbine can easily meet most or all of your electrical needs.

3- Hydro power:

Hydro electric power plants can be installed near lakes or rivers and the movement and pressure of water helps in conserving energy. By building a dam or reservoir, the flow of water can be used to turn on the turbine which in turn will generate electricity. As the water flows downstream, kinetic energy is produced which is then converted into electricity with the help of turbines and generators and later supplied to businesses and industries.

4- Biomass energy:

It used from living things to produce wood fires for cooking purposes and generate fuel for machinery. The energy from these living things is burned and converted into heat and electricity. The most common example of biomass materials are wood or wood residue, agricultural, farm, household and industrial waste. Biomass is widely used for cooking and heating purposes in underdeveloped countries

5- Air source heat pumps:

Air source heat pump is a type of heat pump that absorbs heat from the outside and releases it inside. It uses a compressor to extract heat from the air and boost it to a higher temperature. The heat is subsequently transferred to your home’s heating system. It is beneficial in keeping your house warm and saves a lot of electricity bills as compared to using electric heaters. The process is similar to air conditioners but in reverse.
