Energy crisis means shortage of energy that made by human. This usually involves a shortage of oil, electricity or other natural resources. Energy crisis often leads to economic recession. From the consumer's point of view, the rise in the price of petroleum products used by cars or other means of transportation has reduced consumer confidence and increased their spending. The energy crisis is imminent. The modernization of the world economy benefits from the extensive application of fossil energy, such as oil, natural gas, coal and nuclear fission energy.
So it is an economy based on fossil energy. However, in the first half of the 21st century, the resource carrier of this economy will be exhausted rapidly. The reserves of resources are not unlimited. There are not many reserves that are easy to be exploited and utilized. The development of remaining reserves is becoming more and more difficult. To a certain extent, it will lose the value of continuous exploitation.
The way out to overcome the energy crisis: vigorously develop renewable energy.
To replace biochemical resources with renewable energy and raw materials and carry out a new industrial revolution is not only for the sake of survival, but also for the sustainable development of the world economy. In the face of the current energy crisis, the world has realized that it is necessary to adopt the strategy of opening up resources and reducing expenditure, that is, on the one hand, saving energy, on the other hand, developing new energy. First save energy and improve energy utilization.
At present, some industrialized countries in the world are taking energy-saving measures, combined thermal power is one of the hot topics. The energy efficiency of ordinary power plants is only 35%, and as much as 65% of the energy is wasted as heat and white water. Combined heat and power will use this part of heat to generate electricity or heat for Industry and family, so the energy utilization rate can be increased to more than 85%, greatly saving primary energy. Second developing "green energy" is an important way to solve the energy crisis.
Solar energy, geothermal energy, wind energy, ocean energy, nuclear energy, biological energy and other energy existing in the nature are called "renewable energy", which is also called "green energy" because they do less harm to the environment. Developing "green energy" is an important way to solve the energy crisis. Finally, many scholars think that the main reason of the world energy crisis is that the price of oil is too cheap, which makes the world over rely on it and consume it quickly. They advocate reducing the dependence on fossil fuels and increasing the research funds for the research of energy fuel substitutes. At present, the main alternative energy sources are: fuel cell, methanol, bio-energy, solar energy, tide Xi energy, wind energy, combustible ice, etc. But so far, only hydro power and nuclear power have obvious effects.
The energy crisis is one of the most important issues in today's society. I hope that human beings can recognize this issue, fully prepare, actively formulate policies, implement actions, protect our ecological environment and protect our planet.The energy crisis is one of the most important issues in today's society.
