The Challenge
whether people can live in the near future with much less combustion energy
Gradually, more and more people are becoming convinced that generating energy from renewable sources is the only way to meet our rapidly growing energy needs in a sustainable and environmentally friendly way. In the course of time, all the other energy sources have proved to be unsuitable, expensive, or even harmful.
The reason for that is simple: the global population is constantly growing. We need more and more energy, and we are forced to exploit the resources of the earth. Because of this, we are constantly and profoundly changing the environmental balance on our planet (gases and other substances). For example, let us look at the incineration sector. The IEA (International Energy Agency) quoted a worldwide daily consumption of about 85 million barrels of oil in 2012, with increasing tendency. In addition to that, there is coal and gas combustion.
Fossil resources are running out, and carbon dioxide (CO₂) emissions are increasing unpredictably. In fakt, the expelling of CO₂ is for the Earth a problem among others, but it can be for us humans extremely dangerous. It is highly likely that we won't have any clean air to breathe in several decades, and we will probably suffer from a lack of oxygen.
Human-caused climate imbalances are real, and the list of difficulties arising from the overuse of combustion energy is long. To solve all these problems, we must be able to gradually reduce this type of energy by at least 80%.
