What are the two major changes in the energy structure of Shijie?

The first time was from18th century to coal. The second time was from the 1920s, when it switched from coal to oil and natural gas. Now, the world energy is undergoing the third great transformation, that is, gradually shifting from oil and natural gas to new energy.

Coal, oil and natural gas are all non-renewable fossil fuels. If you use a little, you will lose a little, and you will use it all one day. In addition, the rise of the new technological revolution has brought many new production systems, and correspondingly put forward new requirements for the energy system, especially the use of renewable, dispersed and diversified energy as much as possible. Therefore, experts believe that new energy is the driving force of the world's new industrial revolution and the foundation of the future world energy system. In other words, new energy will surely become the protagonist of the future world energy stage.

According to experts' prediction, nuclear energy and solar energy will become the pillars of the world energy system in about half a century, that is, around the middle of 2 1 century.

Today's mankind has entered the information age. Today's energy does not refer to one or two single substances, but refers to coal, oil, natural gas, hydropower, nuclear energy, solar energy, geothermal energy, wind energy, ocean energy, biogas energy, hydrogen energy, electric energy and so on.
