Renewable Energy – Definition, Sources, and, Benefits.

Renewable energy is frequently used to generate electricity for the grid, heat and cool air and water, and power stand-alone equipment. Renewable energy accounts for around 20% of worldwide energy consumption, including about 30% of electricity.

What is Renewable Energy?

Renewable energy is the type of energy that is derived from renewable resources that are replenished naturally on a human timeline.

Sunlight, wind, rain, tides, waves, and geothermal heat are all examples. Some renewable energy sources are not sustainable, despite the fact that the majority are. At the current rate of utilization, some biomass sources, for example, are considered unsustainable.

Sources of Renewable Energy

Depending on the area and season, Renewable energy comes in a variety of forms. For example, some locations get gale-force winds, but due to gloomy weather, sunlight is insufficient.

Some sources of Renewable energy are:

Wind Energy

Wind turbines are used to generate Wind Energy

To utilize gale-force winds, we need to build large turbines in windy areas. Wind farms can help rural and remote areas to have green electricity.

Solar Energy

Solar energy is the only source of renewable energy that can be easily harnessed at home. To use solar energy and lower your energy bills, you only need to purchase solar water heaters or solar panels. PV panels come in a variety of shapes and sizes, and you may choose the ideal one for your home based on price, efficiency, and other factors.

Hydroelectric Energy

Hydroelectric power is similar to wind energy technology in that it uses water instead of air as the working fluid. Large dams and turbines may be costly, but they will generate a significant amount of electricity.

Geothermal Energy

Geothermal energy is another clean and renewable energy that can be regarded as a sustainable source of power.

Geothermal Energy is the heat within earth that can be harnessed in some areas.

Tidal Energy

The hydropower energy we may receive from tides is known as tidal energy. Tidal Energy is also known as ocean energy. This energy is commonly lumped under the hydroelectric category rather than a separate one.

Hydrogen Energy

Hydrogen is the most plentiful element on our planet, with water accounting for two-thirds of it. If this element can be separated, it can be utilized as a carbon-free fuel.


Biomass energy is the heat we can derive from organic waste by burning them. It’s regarded as a renewable energy source because we always regenerate organic materials, mostly plants.

Advantages/Benefits of Renewable Energy

There are several benefits associated with using Renewable energy. These include;

1. Renewable Energy sources are sustainable

A renewable energy source is sustainable, which means it will not run out very soon, as the term implies.

For example, the sun is predicted to shine every morning for at least another 4.5 to 5.5 billion years, making it a renewable energy source. This is perhaps the most significant distinction between renewables and fossil fuels.

2. Renewable Energy Is Environmentally Friendly

Renewable energy sources are natural sources of energy and hence can be considered environmentally friendly. Although renewable energy methods can produce some emissions, they will emit the least amount of carbon and greenhouse gases to the environment when used.

When compared to fossil fuels, there is a huge difference. As a result, when Renewable Energy is used, catastrophic environmental issues such as global warming, climate change, and poor air quality are reduced to a minimum.

3. Renewable Energy technologies creates lots of jobs

Renewable technology, in addition to having a positive impact on the environment, can also have a positive impact on the economy. This is particularly crucial in some underdeveloped areas. This is a relatively young and steady work market that has the potential to empower people in low-income communities.

Renewable jobs can help to alleviate poverty all across the world with a coordinated effort and judicious investment. It may also hinder people from emigrating from rural to urban regions. Governments can compensate them fairly for producing renewable energy on their farms.

4. Renewable Energy Technologies Require Less Maintenance Cost

When you compare renewable energy technologies to fossil fuel power plants, you’ll see that they have less moving or combusting parts. Solar energy systems do not require any spinning parts, notwithstanding the presence of turbines in wind farms and hydropower plants. This increases the durability of renewable energy technology, resulting in lower maintenance and repair costs. In general, the operating costs of renewable energy plants are much lower than those of typical power plants.

5. Renewable Energy Can Increase Public Health

With Renewable energy, we will have healthier air and soil since greenhouse emissions and other damaging pollutants is reduced. As a result, public health will improve, and individuals will live better lives. Furthermore, a healthier population will result in a large reduction in the annual health expenditure that individuals and governments should set aside.

Scientists have attempted to make fossil fuel technology less polluting while maintaining their efficiency. Renewable energy technologies, on the other hand, are far healthier than traditional technology.

6. Prices for energy can be reduced with renewable energy

With the recent price hikes in other forms of energy, especially, oil and gas, Renewable energy can be of considerable assistance in this regard, reducing the turbulence and improving the global energy market’s stability. Because renewable energy just requires a little initial investment and does not require the usage of fossil fuels.

Using traditional technology, on the other hand, necessitates a considerable budget for fossil fuel prices, which are susceptible to constant inflation. Prices in this market will fluctuate more smoothly as countries lessen their reliance on fossil fuels.

Disadvantages of Renewable Energy

Some disadvantages of using Renewable energy is discussed below

1. The availability of renewable energy is not constant

Renewable energy sources are natural forces that are heavily influenced by the weather. As a result, renewable energy sources like solar cells will be less useful when the weather is unfavorable.

When it rains, for example, your PV panels are unable to generate electricity, forcing you to rely on traditional power sources. This uncertainty is the most significant disadvantage of relying on renewable energy technologies.

2. Renewable Energy Is Expensive to Start Up

Renewable technologies have a high initial cost and are sometimes prohibitive when compared to the amount of energy they can provide.

Renewable energy gadgets, such as PV panels, are, in fact, relatively expensive to manufacture and install. That is why governments are allocating significant funds, such as solar panel incentives, to aid the growth of these technologies.

3. Developing renewable energy sites requires a lot of space

We need a lot of room to harness nature’s forces. This will create a slew of issues for renewable energy facilities. In comparison to regular power plants, setting up renewable energy farms requires more acreage of land.
