An illustrative fact: Man consumes in a year what nature takes a million years to produce. reservations fossil fuels they are not unlimited, they are consumed at a much higher rate than they are produced, and in this case, as we mentioned, it took millions of years to be produced. For example, if we continue at this rate of oil consumption, it is estimated that all reserves of this fossil fuel will be depleted in about 100 years, according to the UN.
Change greenhouse effect: global warming
The greenhouse effect, in relation to the earth, is the ability of the atmosphere to retain heat.. This is because gases in the atmosphere are transparent to solar radiation but opaque to infrared radiation emitted by the earth, meaning that heat is trapped between the atmosphere and the earth. Without this phenomenon, the average temperature of the world would be -18C.
One of the gases that allow the greenhouse effect is CO2 (carbon dioxide). Burning fossil fuels releases more carbon dioxide (its concentration has doubled since the beginning of the 20th century) resulting in extreme heat or global warming, resulting in the well-known climate change.
death in the population
Fossil fuel emissions are the cause of pollution that kills large numbers of people on the planet each year. Atmospheric pollution in cities, according to UN data released to the public this year causes premature death nine million people year, That’s double the number of Covid 19 victims.
Acid rain
Combustion of fossil fuels releases large amounts of sulfur and nitrogen oxides. substances that react with gases from the atmosphere and then fall into acid (sulfuric and nitric) form, increasing the acidification of water in general. This precipitation, called acid rain, damages vegetation, accelerates soil and water pollution, and corrodes buildings, metal structures and vehicles.
War conflicts / social tensions
The main deposits of fossil fuels are concentrated in very specific places on the planet, they are not everywhere. this The control and exploitation of these deposits is the cause of conflicts, wars and social tensions. It’s what we see in the media every day. Most of the wars in recent years have resulted from the control of these energy sources on which many countries depend.
social imbalance
We must add another fact to the obvious differences between rich and poor countries: A quarter of the world’s population consumes 3/4 of the total primary energy (produced by fossil fuels) in the world. This means that not everyone, reserved for a fraction of the world’s population, has access to gas or oil. As such, it is a cause of social imbalances and inequality, which in turn creates conflicts and tensions.
Against this background, the question we ask ourselves makes sense. Is there no alternative? Of course yes: renewable energiesutilizing natural and non-fossil energy sources.
Alternative: clean energies
Faced with all this accumulation of problems, the use of clean electricity in the transport sector or renewable energies for domestic consumption offers a number of improvements:
Elimination of local atmospheric emissions
Electric cars, especially in urban environments, suppressing the direct emission of particulates and oxides of nitrogen and sulfur which cause serious public health problems, especially related to cardio-respiratory diseases.
noise reduction
Most of the vehicle noise is produced by the diesel and gasoline combustion engine with much lower noise emission than electric vehicles.
Lower CO2 emissions
emissions greenhouse gases are minimized with electricity by using other energy sources and not just petroleum derivatives. Using electricity from renewable energy facilities reduces the emissions of these gases that contribute to climate change processes.
Reducing external dependency
Clean energy sources such as wind, solar, hydro, biogas and others inexhaustible and spread all over the planet. They are not located in a specific country and are not the exclusive property of anyone. Therefore, they allow for energy independence, which is so necessary at a time like today, when Europe has to make undesirable political balances in order not to lose gas from Russia. Likewise, as they are universal energy sources, they are in favor of social equality when it comes to access.
