So what are the main types of green energy? There are a number of different sources, some of which we have already discussed in previous posts. A few of the most common include:

Solar energy – solar energy can be harnessed with the use of solar panels and is used to heat water or for electrical generation.

Wind energy – wind farms can be found across the globe, some producing large amounts of electricity. Wind energy is also used to power small turbines and pumps.

Hydroelectricity – this source uses dams to capture the power of falling water and is mostly used by countries that have lots of rivers and lakes.

Geothermal – heat from deep below the earth’s surface can be used to generate electricity and heat homes.

There are various different types of green energy, and all of these are energy sources that are environmentally friendly. The main types of green energy include:

Solar Energy – This is a type of energy that comes from the sun. There are various ways this can be converted into a useful form of energy, including photovoltaic cells which convert the sun’s rays into electricity, solar heating and passive solar heating.

Wind Energy – Wind power is one of the main sources of renewable energy and is generated by wind turbines. There are both onshore and offshore wind farms that generate this type of power.

Hydroelectric Power – Water is used to power generators in hydroelectric plants, where the kinetic energy from moving water is turned into electricity through mechanical means. This can come from either dams or tidal movements.

Geothermal Energy – The heat energy produced by the Earth’s core can be harnessed to produce electricity or heat buildings. This is gained by drilling deep into the Earth’s crust to access the steam produced by this natural occurrence.

Biomass – Biomass is made up of organic materials such as waste products and crops that can be converted into a renewable and sustainable fuel source.

By definition, renewable energy is one which can be replenished within a human lifetime. This is a broad term, and covers many different types of energy sources. Green technology is a blanket term for the technologies that are being developed and used to improve the environmental impacts of human activity.

The main difference between green energy and green technology is that green technology is more focused on making current technologies more environmentally friendly through improved design. Green energy focuses more on developing completely new methods of harnessing power from renewable sources.

In short, green energy refers to the harnessing of clean, renewable forms of energy, whereas green technology refers to making current technologies more environmentally friendly.

Renewable energy obviously comes in many different forms: solar power, wind power, hydroelectricity… So let’s take a look at some of the most common types of green energy:

Solar Power: This form of renewable energy relies on sunlight as its source; solar panels are used to convert the suns rays into electricity which can then be used to power buildings and other electrical devices such as lights and appliances

Wind Power: Wind turbines are used to generate electricity using wind as its source; usually these turbines are placed together in “wind farms” due to their large size.


As more and more people become aware of the importance of green energy, the demand for it grows. Green energy refers to different types of energy that are renewable and can be used without damaging the environment.

Wind Power

Solar Power

Geothermal Energy


There are many types of green energy and the following is a list of the most common forms of renewable energy in use today.

Solar Power

Solar Power is derived from the light and heat produced by the sun’s radiation. It can be used in two ways, either directly (e.g. using solar panels) to generate electricity or indirectly by using it to produce steam which then drives turbines to generate electricity.

Wind Power

Wind power is generated on a large scale by the use of modern wind turbines situated on land or at sea. Wind power can also be generated more locally by the use of small scale turbines for example on buildings.


Hydropower comes from falling water producing kinetic energy that can turn a turbine used to generate electricity. Many dams around the world have been built for this purpose and it is one of the oldest forms of generating electricity after burning fossil fuels.

Geothermal Energy

Geothermal Energy is generated from heat inside the earth (geo = earth, thermal = heat). This energy can be used to heat buildings or to turn steam turbines and generate electricity.

The topic of green energy is one that is on the forefront of most people’s minds. The earth is getting warmer, and we need to find ways to reduce our carbon footprint. Green energy can be defined as a variety of different energy sources that are considered to be environmentally friendly and non-polluting, such as geothermal, wind, solar, and hydro. These energies are renewable in that they are constantly replenished and will never run out.

Green energy has been an increasing concern for several years now. In fact, when the first Earth Day was celebrated in 1970, it was called “A Day of Concern” because there were very few people who had any idea what it was all about. Today, however, there is a great deal of interest in these sources of power and there are even some countries that have begun investing heavily in research into green technology.

The first step in understanding green energy is to learn about the various types of renewable energy that exist and how they work. Wind power uses wind turbines to generate electricity; solar power uses sunlight for heating water; geothermal power utilizes steam from hot water beneath the earth’s surface; and hydroelectric power harnesses the movement of water by using dams or other forms of containment to produce electricity from the motion of water

Green energy is a term used to describe sources of energy that are considered to be environmentally friendly and non-polluting, such as geothermal, wind, solar, and hydro. Sometimes nuclear power is also considered a green energy source. Green energy sources are often considered “green” because they are perceived to lower carbon emissions and create less pollution.

Sources of green energy generally require significantly more upfront capital to develop than fossil fuel sources, such as coal or natural gas; while fossil fuel sources may carry a smaller environmental cost, they often carry a larger financial cost.
