Climate change is brought on by greenhouse gas emissions into the atmosphere, such as carbon dioxide. About 25% of the power, 6% of the heat, and 5% of the transportation fuel in 2016 came from renewable sources. Utilizing renewable energy sources helps to lessen the consequences of climate change by reducing greenhouse gas emissions 1 substantially.
Renewable energy sources can be generated nearby or on-site (like wind and solar energy) (such as biomass). Utilizing renewable energy can boost energy price levels for businesses and increase supply security because it is generated locally, making it simpler to forecast future energy costs. This simple renewable energy infographic presentation helps you to deliver a detailed idea about renewable energy.
Renewable Energy: What Is It?
Renewable energy is defined as energy that is produced continuously and spontaneously in the environment. The sun, wind, waves, and geothermal heat from the Earth can all provide this energy. In addition, renewable energy can be generated from plant materials like wood or crops planted expressly for fuel.
Byproducts from manufacturing and other operations also contain organic fuel sources. These can, in certain cases, be transformed into renewable energy utilizing methods that don’t harm the environment.
Biomass fuels can be substituted, and although they release CO2 when burned, it is typically equal to the amount that was absorbed by the biomass during growth, making them believed to be carbon neutral. However, biomass has a given emissions factor, accounting for CO2.
The Most Popular Types Of Renewable Energy
In both the UK and the US, wind power is the main source of renewable electricity. Wind turbine blades are spun to produce power in onshore and offshore wind farms. By rotating a driving shaft and gearbox, which is coupled to a generator, the turbines transform the kinetic energy of the rotating blades into electrical energy. The national grid is then supplied with greater volts of electricity.
Given that sunlight is one of the most readily available energy sources on Earth, it makes sense that it would rank as the top renewable energy source. Of course, location, season, and time of day all have an impact on how much sunlight we receive. The quantity of solar energy we can utilize varies depending on the time of day, the season of the year, as well as our geographic location, despite the fact that it may seem like the ideal renewable energy source.
Hydropower is produced by utilizing the action of falling or streaming water. Dams often have hydroelectric power plants, which produce electricity through underwater turbines that spin a generator. In addition to employing ocean pressures to produce electricity at the mouths of big bodies of water, wave and tidal power are also included under the umbrella term “hydropower.”
Geothermal energy can be utilized to heat homes directly or to generate power by utilizing the natural heat that exists beneath the Earth’s surface. Geothermal energy is of minor importance in the UK compared to nations like Iceland, where geothermal heat is considerably more freely available, despite the fact that it harnesses a power that is just beneath our feet.
This is an additional hydro energy source that powers turbine generators with twice-daily tidal currents. Even though the tidal flow isn’t constant, unlike some other hydro energy sources, it is very predictable and may therefore make up for times when the tide current is weak.
In this process, solid fuel created from plant resources is transformed into electricity. Although the core of biomass is the burning of organic materials to create electricity, this process is now cleaner and more energy-efficient. Biomass creates power at a significantly lower financial and environmental cost by turning home, industrial, and agricultural waste into solid, liquid, and gas fuels.
Examples of non-renewable energy sources include coal, natural gas, and oil, which are fossil fuels. These sources can be found in nature, but their supply is limited.
Non-renewable energy sources have the drawback that they frequently require hundreds of thousands of years to originate and must be mined and burned in order to produce the energy needed to produce electricity. They also release damaging greenhouse gases when they’re burnt.
Clean Energy, Green Energy, And Renewable Energy
Although the phrases “green energy,” “clean energy,” and “renewable energy” is sometimes used synonymously, there is a significant distinction between them.
- Electricity generated using clean energy is emission-free. However, there may occasionally be a “carbon cost” associated with its production or upkeep. For instance, in order to build hydroelectric facilities with a dam, natural areas must be cleared, and this effort frequently results in carbon emissions.
- Green energy is produced entirely naturally and has little to no negative environmental effects during production or consumption.
- They both have the potential to be renewable, which basically means that their source is inexhaustible.
Consequently, while the majority of sources of green energy are renewable, not all green energy sources are renewable.
Future Of Renewable Energy
The demand for energy to power our homes, businesses, and communities grows along with the global population. Maintaining a sustainable energy level and preventing climate change need innovation and expansion of renewable energy sources.
The International Energy Agency (IEA) predicts that by 2024, 30% of the world’s electricity will come from renewable sources, up from the current 26% share. The IEA’s executive director, Fatih Birol, stated that “renewable energy is at a critical juncture right now.”
Renewable energy is the only energy for future generations, and knowledge about its importance and conservation should be shared worldwide.
