Green energy is the energy that is generated from natural resources such as wind, sunlight, and water. Although there are lots of differences between renewable energy resources and green energy resources that we are going to explain in this article but this energy comes from renewable energy resources.
Green energy sources are better than others because they do not harm the environment through different factors such as the greenhouse releasing gases into the atmosphere.

How does green energy work?
Green energy comes from renewable energy technologies such as wind power, solar energy, geothermal energy, biomass, and hydroelectric power. The working ways of these technologies are totally different from each other, no matter if they are getting power from sunlight as the solar panels, wind turbine, and the flow of water to generate energy.
Green energy sources cannot produce pollution as the other energy sources because it is found with fossil fuel. It means that not all resources used by renewable energy sources are green energy sources. Just like power generation that burns organic material from forests may not necessarily be green because of producing CO2 by its burning process.
Green energy resources are usually recharged, as opposed to fossil fuel sources like coal and natural gases that can millions of years to develop. Green energy sources are also avoiding the operation that can damage the ecosystem.
Types of green energy sources
The common sources of green energy are wind energy, solar power, and hydroelectric power. Solar power and wind power can be produced on a small scale like people’s homes and can be generated on a large scale like an industrial scale.
There are almost 6 common types of green energy sources:
- Solar energy.
- Wind energy.
- Hydro energy.
- Tidal energy.
- Geothermal energy.
- Biomass energy.
We are going to discuss how these energy sources work, their use, and how they generate green energy without polluting the environment.
Solar energy
We all know that sunlight is the most lavish and freely available source of energy. The amount of energy that we get from the solar energy that reaches the surface of the earth in our hour is more than the total energy requirement of the planet for a whole year. It sounds like a perfect renewable energy source but the amount of energy that we can get from solar energy is different according to the time of the day and geographical location. It also depends on the season as the sun shines brightly in the summer and provides more energy than in winter.
However, this green energy source is produced by using photovoltaic that detain from the sunlight and then turns it into electricity. Solar energy is also used to heat water, cooking, lighting, and building heating. This energy source, solar energy, has become more affordable now for some domestic uses such as the lighting in the garden, and also for large scale to provide energy to all neighbourhoods.
Wind energy
Uneven heating of the atmosphere by the sun, differences in the earth surface, and rotation of the earth cause wind. It is a clean source of energy. Wind turbines convert the energy found in the wind into electricity by rotating propeller-like blades around a rotor. This wind energy is extremely suited to offshore and higher altitude sites. It is a clean fuel source and sustainably very cost-effective. Wind energy is also an ideal domestic source of energy. You can create wind turbines for exciting farms and raches.
Hydro energy
Hydro energy is also known as Hydroelectric energy as a renewable energy resource. It is one of the most commercially generated energy. This energy is produced by building a dam or barrier. A large water body can be used to create and control the flow of water. The flow of water then drives a turbine that generates electricity. This energy source is productively better and more reliable than the solar energy and wind energy sources. This energy resource also allows storing the electricity for later use when the demand reached a peak. Hydropower can even work at small scales using the flow of water through pipes at home and rainfall, tides in the ocean, and from evaporations.
Tidal energy
Tidal energy is another source of hydroelectric energy that uses twice-daily tidal current to drive turbine generators to develop energy. Some other hydro energy sources just unlike the tidal flow are not constant. This tidal energy is highly predicted and can compensate for the period when the tide current is low.
Geothermal energy
This type of green energy uses thermal energy that is already stored under the crust of the earth. It means that it harnesses the natural heat to generate energy that can be used to heat the home and to generate electricity. This energy resource requires drilling to access and once it is tapped into it is the most huge resource of energy. Geothermal energy is used for bathing in hot springs and can be used for steam to drive turbines that generated electricity. This energy resource is freely available and many states have more easy access to geothermal resources, it is also very eco-friendly just the drilling process needs close mentoring.
Biomass energy
This renewable energy source needs careful management if you want it as a green energy sustainable resource. The biomass energy converts the energy from wood waste, sawdust, and combustible organic agriculture waste. Although Biomass energy is burning organic material to produce energy. but it is more cleaner and more energy-efficient process. By converting the industrial, agricultural, and domestic waste into solid, liquid, and gas biomass generates energy at a low environmental and economic cost.
Importance of green energy resources
Green energy is more important for the environment as it replaces all the negative effects of fossil fuels. All green energy sources drive energy from natural resources and it is also very clean because it emits no or few gasses related to greenhouses.
