What is Renewable Energy?

Renewable Energy is a type of energy generated from natural resources that are constantly replenished and is a crucial concept to grasp. Renewable Energy is generated by harnessing natural resources such as sunlight, wind, and water to produce electricity or heat.

The primary goal of Renewable Energy is to create a sustainable energy supply that doesn’t deplete. This contrasts with non-renewable sources like fossil fuels, which are finite and will eventually run out.

Grasping the concept of renewable sources is a crucial step towards transitioning from non-renewable sources to more sustainable ones. It empowers you to make informed decisions about your energy consumption.

How does Renewable Energy differ from non-renewable Energy?

Non-renewable sources like fossil fuels, such as coal, oil, and gas, are commonly used to generate energy. However, burning these fuels releases greenhouse gases that are detrimental to the environment.

In contrast, renewable energy sources produce significantly fewer emissions, making them a more environmentally friendly choice. Understanding this difference underscores the urgency of transitioning to renewable energy sources.

Is Renewable Energy the same as clean or Green Energy?

Renewable resources are often associated with terms like ‘clean’ and ‘green’ Energy. However, it’s important to understand the subtle differences between these terms. Renewable Energy is generated from sources that can be recycled.

On the other hand, clean energy is created from sources that do not release harmful environmental emissions like CO2, making it environmentally friendly.

Green energy is generated from natural sources, making it sustainable. However, not all types of renewable energy are clean or green, highlighting the need for a nuanced understanding of these terms.

Now you know the difference between these types. This means that not all types of renewable Energy are clean or green. In this article, I will discuss popular primary renewable energy sources.

Primary sources of renewable Energy

1. Solar Energy
2. Wind Energy
3. Biomass Energy
4. Hydro Energy
5. Geothermal Energy
6. Ocean Energy

1. Solar Energy

Solar Energy is one of the most popular renewable sources because it harnesses the sun’s heat to generate thermal or electrical energy. Thanks to numerous technological developments, solar energy can provide us with heating, cooling, electricity, and fuel options for multiple applications.

However, it’s important to note that access to solar power is not unlimited. It depends on geographic location, season, and the right time of day. For instance, areas with more sunlight and less cloud cover are more suitable for solar energy generation.

2. Wind Energy

Wind energy harnesses wind power (kinetic Energy) into electricity. It requires turbines with blades that drive the generators, which feed electricity to help power the grid. Many parts of the world have high wind speeds, but only some places are suitable for wind turbines.

3. Biomass Energy

Biomass energy is generated from organic materials, including coal, wood, dung, and plants. While it is a renewable source, it involves burning organic materials, which emit greenhouse gases into the atmosphere at a much lower rate than fossil fuels but still has the potential to harm the environment. Therefore, it should be used in limited applications to avoid significant environmental impact.

4. Hydropower

Hydropower is generated similarly to wind energy, as it also uses turbines. The difference is that hydroelectric Energy uses the speed of moving water in rivers or waterfalls to spin the turbine blades and harness the Energy of water.

Hydropower can be generated from reservoirs and rivers. While hydropower reservoirs have multiple uses, such as providing drinking water, navigation services, water irrigation, flood and drought control, and energy supply, it’s important to note that generating hydropower through hydroelectric dams is not without its challenges.

Many giant dams divert natural water sources, which can harm animals and human populations due to restricted access to the water source. Therefore, it’s crucial to consider the potential environmental and social impacts when implementing large-scale hydropower projects.

To avoid the adverse impact, try to generate hydropower from smaller plants of 40 megawatts so that generating hydropower won’t hurt the environment.

5. Geothermal Energy

Geothermal Energy harnesses the natural heat below the earth’s surface. Hot water reservoirs exist or are made by humans, varying in temperature and depth below the surface. Wells with depth are drilled underground reservoirs that tap steam and hot water and bring it up to the surface to be utilised for various applications, including heating, cooling, and generating electricity.

6. Ocean Energy

Harnessing the power of the ocean is a viable and great option, but it is still in its developmental stage. Ocean energy is a phenomenon that generates power by utilising the kinetic and thermal Energy of seawater and waves to generate electricity and heat. Although several devices and prototypes to develop ocean energy are being explored, some approaches may harm wildlife.

Benefits of Renewable Energy

Renewable Energy is not just a sustainable choice but also a smart financial decision. By harnessing the power of natural resources, you can significantly reduce your energy consumption and utility bills. The initial investment in setting up the materials and their installation is all it takes, and the natural supply, i.e., sun and wind, will be readily available for you to utilise.

This reduces your energy costs and minimises the negative impact on the environment, empowering you to take control of your energy consumption and feel more environmentally responsible.

• Compared to fossil fuels like coal, gas, and oil, renewable resources have zero or very low greenhouse gas emissions. Reducing your carbon footprint will fulfil your responsibility towards the environment.

• Renewable Energy is based on generating energy from natural resources that can be replenished over time, meaning it is inexhaustible.

• If you live in a remote area without a connection to the power grid, renewable energy can be a great way to generate electricity through solar power.

Lastly, renewable Energy promotes health and well-being by minimising the negative impact on the environment. By reducing harmful gas emissions, renewable energy sources contribute to cleaner air and water, improving public health.

Additionally, the shift towards renewable energy can create new job opportunities and stimulate economic growth, offering a hopeful future for society.

How can the people of Britain benefit from renewable energy sources?

Renewable energy sources are not just an alternative but a solution to climate change. Renewables significantly lower greenhouse gas emissions by replacing fossil fuels with cleaner alternatives like wind power, solar panels, and hydropower sources like windmills. This proactive step, even individually, decreases carbon footprints and creates a more sustainable future for all involved, making you feel valued and integral to the solution.

Renewable Energy boosts UK energy security in two ways.
