Different Types of Renewable Energy Sources Explained

Nowadays, Renewable energy is gaining popularity worldwide due to the increasing price of fossil fuels as well as the risk of climate change. At present, there have also been some developments in this area like enhancement in efficiency and reducing prices. All of these developments have enhanced the demand for cleaner and more sustainable techniques of electrical power. Though, there are different types of renewable energies available like solar, biomass, solar, tidal, wind, etc. Each type of energy has its own advantages as well as disadvantages. Many private and public enterprises like educational institutions, government agencies are searching for renewable energy sources to meet up their energy solution requirements. These solutions are exactly found in deep underground, in the air, and also in oceans.

What is Renewable Energy?

The renewal energy definition is – different types of energies that are obtained naturally from the environment. These energies are quickly becoming inexpensive as well as efficient, and that includes solar, biomass, wind, hydropower, geothermal, etc., and. Renewable energy is very beneficial due to their partial negative ecological impact when contrasted to fossil fuels. A long time ago this energy is not used much due to their cost. But some of the energy sources are smart financial choices for hospitals, business, and homes. Particularly, solar energy is the best option for the house owners who want to reduce their environmental track while conserving money.

Different Types of Renewable Energy Sources

There are different types of energies that are considered renewable energies namely solar energy, wind energy, tidal energy, hydroelectric energy, geothermal energy, biomass energy, etc.

Different Types of Renewable Energies
Different Types of Renewable Energies

1) Solar Energy

Solar energy is one of the most popular and also the fastest growing renewable energy sources. As a free renewable energy source, technology has created a technique for connecting the energy of the sun through solar panels. Solar panels are classified into two type’s namely solar thermal, as well as solar PV cells. Solar PV cells absorb the sun’s energy and change it into electrical energy which is used in different applications like electric heating, power appliances, in electric cars, etc. Solar thermal panels use sun’s energy and these panels are used in taps, heating systems, showers, etc. A solar energy is the best option in a rising renewable energy marketplace.

2) Biomass Energy

Biomass energy is most widely used renewable energy. It uses organic materials like animals, plants, and converts them into another form of energy that can be used. For instance, when the plants absorb the solar energy through photosynthesis process, then this energy will pass on through the plant’s organism for making biomass energy. The common type used for generating biomass energy is crops, wood, and compost.  If the Biomass technology is not controlled properly then it can have a harmful effect on the environment.

3) Wind Energy

Wind energy has been using for several years for power windmills, pushing sails, and also for generating force for water pumps. When we contrasted to other types of renewable energies, wind energy is considered steady as well as very reliable.


At first, the wind farm construction was an expensive venture but now the recent developments have begun for fixing the peak prices in wholesale energy markets globally and reduce the profits and revenues of the fossil fuel production companies.

4) Hydroelectric Energy

The hydroelectric energy uses the flow of water to rotate turbines for generating electricity. According to the US survey of geological, this renewable energy provides 20% of the energy in the world energy requirement. There are some issues while using hydroelectric energy.  This energy can be generated from the dammed rivers; otherwise it can have a major effect on the soil as well as wildlife, and also affects on fish communities that must journey through the river dams.

5) Tidal Energy

Tidal energy is the same as wind energy but these are predictable as well as steady. This is the main reason that tidal energy sources are called potential sources. Tidal mills have been used since the ancient days to middle ages similar to windmills.

Usually, tidal energy has faced from relatively high cost as well as incomplete accessibility of sites through suitably high tidal ranges. But, several current technological developments both in technology and design point outs that the entire tidal power availability may be superior to previous, and the environmental costs may be getting down to competitive stages.

The “Rance Tidal Power Station” is the world’s largest tidal energy power plant in France. And in Scotland and Orkney, the first world’s marine energy center, as well as the European marine energy center, was established in the year 2003 for developing the tidal energy & wave energy industry in the UK.

6) Geothermal Energy

The term Geothermal taken from the Greek word Geo (Earth), and it receives the heat from the Earth and converts it into energy. For instance, hot water or steam energy which are generated from the earth can be utilized for generating energy. It is called to be a renewable supply of energy because the water in the Earth is filled by normal rainfall & the heat used is generated through the planet.

Ground basis heat pumps can be fixed to connect the normal heat from underground using fluid tubes covered outside the assets.  The fluid in the tubes absorbs the heat from the ground so it can be used to heat your home and water. For assets that are located close to a river or lake, it is achievable to fix a heat pump for a water source. These pipes are flooded in the water as well as a heat pump drives a heat absorbs liquid during the arrangement of piping. This liquid removes normal heat from the nearby water to be utilized in the seating arrangement.

Advantages and Disadvantages of Renewable Energy Sources

The advantages and disadvantages of different renewable energy types include the following.

Renewable Energy Advantages

    • The renewable energies are secure, plentiful, as well as hygienic to employ when contrasted toward fossil fuels.
    • Multiple types of renewable energy exist
  • Renewable energies provide the base for energy freedom
  • These energy resources are stable
  • Renewable energy is a technology as a substitute for a fuel


  • Some type of renewable energy sources is location-based and commercially feasible
  • These types of energies need storage capacities
  • These energy sources cause pollution.
  • Renewable energies frequently need funding for making them reasonable
  • Some types of energy sources require a huge space

From the above article, finally, we can conclude that this energy is produced from natural processes like sunlight, wind, tides, geothermal heat, water, and also various types of biomass. But wind and solar energy are using frequently across the world, and are both renewable energy examples. The renewable energy facts mainly include it cannot be tired and it is constantly changed. The Union of worried researchers recommends the above renewable energy sources. Here is a question for you, what are the applications of renewable energy?
