We know that there are such a thing as renewable energy, those sources that produce energy from an inexhaustible natural source, such as the sun, the wind and the water. These are all proposed as alternatives to traditional ones, such as fossil fuels.
However, alternative energies do not necessarily have to be considered inexhaustible or come from a natural resource to belong to this vast group of energies that day by day is strengthening the world panorama.
It is then that we can show the basic concept of alternative energies, and these are those that can replace the current energy sources, either because of their less polluting effect, or their ability to renew.
This would include energies obtained through natural resources, biofuels, and nuclear energy. In this article, we will focus on reviewing the advantages and disadvantages of these types of energy for our use.
Some of the possible advantages would be:
The energies of alternative sources have the potential to create a world that depends entirely on themselves. This transition would bring not only advantages for the environment but also the economy and the use of energy in all the most important areas of our history, as it would completely change our world.
They are safe and free of pollutants and are not considered harmful to health, so they are highly recommended for use within urban areas of a city, where they can be in direct contact with the population.
They come from inexhaustible sources of energy and multiple applications such as wind energy, hydraulics, biomass, geothermal, marine and the best known solar energy that is very present in our present as a new method of obtaining energy.
Exploitation of local production
They are considered autochthonous energies because the energy that it produces is used in the same region in which it develops, which drives the industry and generates more employment. It also reduces energy dependence on the outside. No more oil wars.
It is personal energy, and any citizen can become a producer of electricity generated by installations of residential solar panels.
Some important disadvantages of alternative energies are:
Impacts on the natural landscape
The damage to the landscape is something to take an account, in the case of the wind turbines it is said that they produce noise pollution that harms the sense of orientation of the birds or that these collide with the propellers.
Biofuel abuse, you can divert valuable food resources to burn them like gasoline, generating more CO2.
Construction of dams that cut the natural flow of rivers and damage the natural ecosystems that exist on Earth, putting the lives of thousands of species at risk.
They produce less energy than fossil fuels and the cost of storage is high, so it still has high costs that cause an imbalance in a country’s economy.
These would be the most important advantages and disadvantages of alternative energies. You always have to take a look at the bigger picture when considering alternative energy. This gives us a way to better understand how the energy system of our world really works.
