Danger of Global Energy Crisis

Energy crisis refers to the impact of rising energy prices due to the shortage of energy leading to the shortage of energy supply. This usually involves the shortage of oil, electricity and other natural resources. The energy crisis will often cause a recession. From a consumer's point of view, rising prices for petroleum products used in automobiles or other means of transportation have lowered consumer confidence and increased their spending.
In order to cope with the energy crisis, it has become an inevitable choice for all countries in the world to actively seek new alternative energy sources. At present, the development and utilization of hydropower, wind energy, solar energy, geothermal energy, tidal energy and nuclear energy have become an effective supplement to fossil energy, and human society has entered a multi-energy era. However, water energy, wind energy, solar energy, geothermal energy and tidal energy are limited by a variety of conditions.
Nuclear energy is technically mature and can be developed and utilized on a large scale. It is an energy source to make up for the shortage of fossil fuels, reduce environmental pollution and realize large-scale industrial application. The earth's known resources of fissile fuels, uranium and thorium, are more than 20 times the total energy of fossil fuels in terms of their energy content. In addition, there is still a large amount of deuterium on the earth as fuel for nuclear fusion. If commercial controlled nuclear fusion is achieved, the reserves of deuterium and tritium on the earth can be used for 10 billion years according to the current world energy consumption level.
Human beings must estimate the potential crisis caused by the depletion of non-renewable fossil energy resources, so as to shift their attention to the new energy structure and explore, research and exploit new energy resources as soon as possible.
Otherwise, it may cause serious consequences because of taking too much from nature. In recent years, the greenhouse effect, the ozone layer hole, the melting of icebergs, and the increase of acid rain cover are all evidence of the urgent threat of the energy crisis.
Sunlight can be converted into electricity, heat and water to make fuel. Electricity can drive vehicles on earth, launch spacecraft with magnetic railguns, or blast rockets into space by firing the air or heating the tanks on them with millimeter waves. Hydrogen and oxygen from the water could be used as fuel to drive vehicles or launch rockets on earth, or to support fusion propulsion systems based on nuclear explosions rather than controlled fusion. A civilization without fossil fuels or controlled fusion can still expand into space.
There is enough electricity and heat energy, can be biomass pyrolysis, catalytic hydrogenation, into fuel, gas, coke. Plastic can be recycled in machines, or it can be made from biomass or even carbon dioxide -- ultimately, organic polymer materials require carbon sources rather than specific fossil fuels.
In other words, the total release of fossil fuels on the planet does not lead to a scenario of no fuel, no plastic.
