The Primary Types Of Clean Energy

Renewable energy is becoming more widely used and it is important to know the different types that are available. Most clean energy can be used for commercial and residential purposes. There are 6 primary types that you should consider.


The most commonly known type of clean energy is solar power. Solar power uses the energy generated by the sun to power electrical devices. Solar panels are used to collect the light and transform it into energy that can be used by common devices. There are actually two different types of solar power and they are solar photovoltaic and solar thermal.


Wind power is becoming more prevalent as a means of generating renewable energy. To generate the energy a wind turbine will be erected and when the turbine moves with the wind it generates energy. Wind turbines are largely used in Europe as the climate is ideal for turning the kinetic energy of the wind into mechanical energy.


Biomass energy is not as commonly used, but is energy that is generated from organic materials. To create biomass energy these organic materials will need to be burnt or converted into methane gas, biodiesel fuels, and ethanol. For use in residential settings biomass energy can be generated from a wood-burning oven, but it is unlikely that residential biomass energy can be created by the conversion of the organic substances.


Geothermal energy is derived from the heat that is generated by the Earth. Hot water or steam that is generated naturally can be used to create energy and this will be considered geothermal. There are a number of geothermal systems which can be used to heat a building by drawing the heat from the ground and pumping it into the building.

Hydro Power

Hydropower is a clean energy which is generated from moving water. The moving water will be passed through a water turbine and as the turbine spins it will generate electricity. This conversion is similar in nature to wind power as the kinetic energy of the water is changed into mechanical energy. The water used for this energy is often recycled back into the system or forms part of a dam where natural flowing water is used.


Biofuels is a type of clean energy that is generated from the burning of animal or plant substances via combustion. One of the problems faced with the use of biofuels is that it cannot be easily transformed into a liquid state. This means that biofuels are not able to power vehicles which use petrol in its current form. The methods of creating biofuels are also challenging and difficult to maintain on large scales.

There are a number of different types of clean energy that can be used to replace coal, gas, and oil. Many of the more commonly known clean energy sources can be used for commercial and residential properties, but others are harder to use for residential settings. If you are looking at having clean energy in your home you have to consider your climate and which option works best.
