How long can we rely on Renewable Energy Sources?


Need for Growth

Electric energy has become a basic need for humans for survival. Almost every activity is directly or indirectly connected with electricity. Since its invention, electricity generation sources have been changing and evolving to increase its density of production. Currently, coal is the major source of electricity generation globally and is also one of the major contributors to greenhouse gas emissions. Hydropower plants on the other side are the second most popular source of energy generation as it was one of the first sources of electricity generation. But, the electricity demand kept rising as innovative products came into existence.

As the demand grew, pressure builds on power plants to match the desired demands. Petroleum products are currently leading the charge of energy and power, but soon electric energy will replace it as the reserves of petroleum wells begins to deplete. Currently, we are generating electric power from multiple sources in different parts of the world. The USA and other powerful nations were highly dependent on coal power plants, later they realized & started searching for a better and sustainable source of energy generation as there’s a limit to coal as a fuel.

Sources of Energy

The sources of electricity generation are mainly divided into two parts: Renewable/non-conventional sources and Non-Renewables/conventional sources. We are almost familiar and known to these sources:

Hydroelectric Power

Hydroelectric plants use hydropower to produce power. In this manner, a dam is based on a waterway to hold water, making a supply, similar to a lake.

Then, at that point, the gathered fluid is driven through lines to the force to be reckoned with. There, turbines and generators are utilized to change the dam content tension into a development, producing power from water.

Thermal Power

Thermoelectric plants are another way of producing electricity. In this case, the system works by heating the water with fossil fuels, including petroleum, natural gas, and coal. The heating produces steam, which is led by pipes to the turbines, making them spin. The turbines are connected to generators that create an internal electromagnetic field, forming electricity.

Unlike the previous option, this electricity source is not renewable, as it is powered by finite fossil fuels. They also cause environmental impact due to the burning of the materials, generating air pollution.

Nuclear Power

Atomic plants utilize radioactive components, like uranium, to produce energy. In this framework, the core of the uranium molecule is broken down, delivering a lot of hotness (energy), which is the reason they are known as wellsprings of “atomic” power. The hotness delivered in these plants is utilized to transform water into steam, which is led by pipes, advancing the development of the turbine that, thusly, moves the electric generator.

The significant benefit of this choice is the usage limit, which gives 1 kWh of energy to each pound of charcoal (453.59 g). In spite of the fact that it merits recalling that it isn’t sustainable, since it needs radioactive material simultaneously.

Solar Energy

We all are known to solar photovoltaic cells or popularly known as solar PV panels, are the most utilized sources of renewable energy and contribute in huge numbers in generating electric power. The advancement in its technology has made it possible to afford and install. The current market trend suggests that it will generate electricity effectively if we place it on our rooftop which comprises vacant space and receives ample amount of sunlight in every urban area.

It can solve our basic problems of power cut and charging our small electronic devices by storing the energy generated from solar panels in the batteries.

Wind Energy

Solar panels have a limit in generating electricity as they can be highly productive only on bright sunny days. The wind blows day and night with a certain average speed in selected areas that can be able to generate electricity from wind farms. The functioning is simple; It works through turbines, which look significantly like a pinwheel, that move due to the wind.

It converts wind power into electricity with the help of a generator and rotor, an internal moving part that generates electromagnetic fields that are transformed into electric power.

Dependency on Renewables

Renewable sources are better for climate change and had already contributed to reduce our dependence on dirty fuels like coal and oil resources. According to the data published by IRENA (International Renewable Energy Agency), renewable energy resources contributed to 16% of the total global energy production supply in the year 2019.

As time passes by, the energy sources are getting affordable and more productive that leads to generating electricity as per our need. The point of this article is how long we can rely on these sources as they have a certain life span? There are no further plans on waste management from renewable resources which could lead to a major concern for the future generation. There has to be an alternate plan to overcome dependency on current renewable energy sources.
