Viability of Renewable Energy Sources Such As Hydro, Solar, The Wind, Waste or Biomass, their Pros and Cons and Potential Effects on the Environment


Renewable energy is sometimes referred to us clean or green energy. The energy is often collected from renewable resources. The energy consumed by renewable resources such as hydro, solar, wind, waste or biofuel is generated from solar emission spinoffs, gravitational energy from the moon, and geothermal radiation from the core of the earth. The energy that surge from these sources the biosphere is plentiful, therefore, tapping a small portion will be sufficient to supply the entire energy services that humankind wants.

Viability of Renewable energy sources

Viable energy is referred to the energy that can be used. Viable energy is also defined as energy that can cater for the increasing demand of the population in future. The green energy such as the wind, solar, geothermal, and hydropower can all be categorized under viable energy. These sources have been in use since time in memorial, and they will be in use for the next several decades. Renewable energy is essential and sustainable because a small impact on the environment, vastly available and are replenished naturally. Renewable energy is sustainable because it improves energy efficiency and can be used for a longer time.

There is a chance that fossil energy will be depleted soon from the earth because they cannot be replaced. There is also the threat of dire impacts on the environment which have resulted in climate change and global warming. Many people are becoming aware of these consequences which have led to many governments and societies to move to renewable energy a source that is clean and has less impact on the environment.

Different governments have set aside large investments into renewal energy, such as building and development of solar farms wind farms and big dams along the rivers and the wave’s power stations. With this in place, countries have reduces the over-reliance on fossil fuel to a significant extent, though it will take a long time before people get to fully depend on renewable energy because most the population always have the habit of leaning towards fossil fuel because they are used to it.  The world’s requirement for energy cannot be met by the use of fossil energy.  But if the world continues to rely on this type energy it will lead to permanent environmental consequences which are too large just to be ignored.

Renewable energy sources have been recommended all over the world, but because of some of these sources such as the wind and solar vary, this makes them not to be reliable energy sources, and therefore thy can be depended on a continuous source of electrical power. This means that there is a need for a tailback for the conservative energy so as to give a constant and dependable power to meet the weights of the grid in a growing population.

Benefits and Cons of Renewable Sources of Energy

Renewable energies, on the one hand, are sustainable, continuously restocked, eco-friendly and plentiful, on the contrary, they also have flaws. They incredibly rely on meteorological conditions in that any slight alteration in the weather can decrease the manufacture of energy out of these sources.

The Advantages of Renewable Energy Sources

a) The cost of energy is Stable

The modification of renewable energies is an indication of stable energy costs all over the world. In contrast to fossil energies that escalate or reduce depending on the present increase of prices and the accessibility of the resources, the prices of renewable energies purely rely on the preliminary amount used to install the renewal energies machinery and not on the increased cost of natural resources.

b) They are constant source of energy

Renewable sources of energy are sustainable resources that will not diminish for a lifespan. There is also no likelihood that they will come to an end, for instance, with the rays of the sun, powerful winds, moving water, and heat originating from under the soil, there is an assurance of large and stable supply of energy throughout the world for numerous years.

c) Dependability

Renewable energy sources are permanent and constant. The broad distribution of the wind and solar plants to a wide geographical area minimizes the interruptions caused by the production of electricity. This is because unlike fossil fuel sources that dry up making the whole process to be moved, the distractions of weather in one area cannot be similar to other areas. Additionally, the wind will continue to blow, and the sun will shine all over the globe, and every nation can tap those energies for the production of energy on a vast scale, unlike fossil fuels whose supply is shaken by political uncertainties, strikes, wars, and trade arguments.

d) Renewable energy are environment-friendly

They emit zero or little carbon dioxide and greenhouse gasses. All the renewable sources are friendly to the environment because no toxic gas is emitted that will, in turn, pollute the environment. Hence, using renewable energies intensely decreases the reliance on fossil fuels as sources of energy, thus, reducing air pollution.

e) Create employment opportunities

Renewable energies since its adoption worldwide have created steady and new jobs in the economy of the world. For example, in the UK, US, Germany, and other European countries several employment opportunities have already been generated due to their persistent efforts to expand and boost the usage of renewable types of energy. This is also connected with the continuing vibrant campaigns of embracing renewable energies, which in turn has generated thousands of steady jobs.

f) Low maintenance cost

Immediately they are in position, many forms of renewable resources require a lesser general cost of maintenance as compared to fossil fuel types that need the high cost of operation. This implies that those who own renewable energy amenities will earn high revenues while offering low-cost electricity to the people.

g) Empowers countryside inhabitants

The generation of renewable energy sources mostly happens in rural settings. Local towns would benefit from the generated power, and eventually catalyze the revival of the depressed areas both economically and socially.  Therefore, by electrifying those areas, there will be the creation of unexploited chances for expansion through the upgrading of greenhouses by renewable energies.

h) Enhancements of public health

Fossil fuel emits toxic gasses that are dangerous to the health of humanity if inhaled for an extended period, unlike renewable sources that emit zero or no toxic gasses. This is enough evidence for people to put into consideration the shift from fossil fuel source of energy to renewable sources of energy in future.

Cons of Renewable Energy

As much as renewable energy sources have pros, being aware of their cons may help improve their execution. The cons include;

I)High amount of capital needed to set up the facilities

There is the need for expensive generating infrastructures and an enormous amount of capital outlay to install renewable energy. For instance, to set up a hydro electrical plant, wind turbine, and solar panels will cost a lot of money. Additionally, the facilities need an enormous amount of money to maintain them.

II) Low-efficiency levels

A significant amount of renewable energy cannot be produced over a short period. In addition to that, the technologies used to generate the energies are new to the market implying that they still don’t have the much-required efficacy. This is an implication that investors are not willing to invest in them with fear that they will not get their revenues fast. On the other hand, the raw materials for renewable sources are not obtainable in some areas meaning they have to be transported to the production site lowering the production process.

III) The capacity of the electricity generated.

In comparison with the old forms of energy generation such as fossil oil, production of large quantities of energy production in renewable energy sources is still a big challenge. This means that renewable energy cannot be relied upon to meet the demand of the increasing population. To resolve the issue more facilities would be developed or countries should come up with ways of reducing consumption of energy.

IV) Unreliability of renewable energy

Most of the time renewable energy sources depend on the weather condition to be able to produce energy. If the weather is not okay, it will be difficult to generate power using renewable energy technologies. This typically prompts governments to hold conduct campaigns so as to reduce energy usage to cater for the population.

The effects renewable energies will have on the environment, especially in light of a new Trump administration.

In the U.S there have been great changes made over the past years concerning the move towards renewable energies. This progress has led to an increase in energy security and also has reduced the adverse effects of coal fuel on the environment. Renewable energy sources and the industries that are related to it have made a positive impact on the economy of the U.S. President Donald Trump signed an executive order to revive the coal industry by lifting the moratorium on the federal letting of coal. Even before his presidency, there was speculation that funding on renewable energy will be reduced so that it can be directed to coal fuel. This development will result in one way or another slow the move to the use of renewable energy sources, and also the U.S will be a disadvantage when it comes to its competitors.


Though renewable energy might not do away with all the matters affecting the environment, they produce a moderately low level of gas emissions. Development of policies on renewable energy sources should be built on the understanding of the environmental impacts of substitute sources of energy. These results should include the effects of green energy technologies in comparison to the effects of technologies in fossil fuel energy. Therefore, the move to renewable energies by countries is essential to reducing the effects of global warming and climate change, and in the long run, it will help preserve the lives of the future generations. On the other hand, when Trump was campaigning, he disapproved the production of renewable energies and termed them as high criticizing solar power as not being effective, thus cautioning that wind turbines are dangerous to the birdS as they kill them[18]. However, due to the employment opportunities that the renewable energies such as the wind and solar offer, the tax investment as a result of the services and businesses in those sites, people are not yet sure if Trump will attempt to abolish tax inducements for the wind and solar. Neither are they sure of measures to disapprove renewable energies positively.
