Judge the day not by the harvest you have gathered, but by the seeds you have sown on this day.
Robert Louis Stevenson (1850-1894)
The universe, galaxies, our solar system is a huge world in which our Earth is sheltering, a small grain of sand living according to the laws of this world.
This vast world keeps its secrets. That is why restless human curiosity strives to explore the unknown and asks the question: what unknown forces make the world like this?
But we also need to find answers to other questions. For example, what kind of future awaits us? What can lead to the extinction of life on Earth?
If we decide to find out the truth about our future, then this will be the first step to have time to understand or even save a life from catastrophe.
But first, let's remind how our planet has changed as a result of human activity.
The warming of the planet is causing a threat, and this is no longer something assumed, but has already become a reality. The temperature on the planet is slowly rising. What happens if the temperature does not stop rising?
A lot will change. Ice on the tops of mountains, glaciers in Antarctica and Greenland will begin to melt. The water level in the oceans will rise. Many cities will be under water.
Permafrost will melt, exposing ancient burial sites of animal remains.
This will lead to the emergence of new pathogenic microorganisms and viruses unknown to modern humans. Waves of epidemics will overwhelm the earth.
Therefore, the replacement of polluting energy sources will help in solving this issue.
Humanity is aware of the importance of solving environmental problems, so there is a gradual transition to renewable, alternative energy sources. Such as the use of wind and solar energy.
The use of wind turbines and solar panels to some extent allows us to provide the population with safe energy that is so necessary for everyone. But these “environmentally friendly” species also have their drawbacks. Large areas are needed to obtain sufficient energy.
Solar energy depends on the weather, time of day, seasonality, it is necessary to periodically clean the reflective surface, and the price of solar panels is also high.
When using wind energy, the kinetic energy of air masses in the atmosphere is converted into various convenient types of it. Wind power is an irregular source of energy and depends on the strength of the wind. The unevenness is also associated with both the daily and annual receipt of it. Large wind turbines are difficult to repair, it is difficult to replace parts at an altitude of more than 100 meters. Wind power plants produce noise and vibration, so they are placed in an open area.
