The light "shines" and the wind "blows" and the "crackling" sound! Don't you want to know how to play with energy in the future?

Children in the future may see snow in winter, but they may never see smog again. Smog is a compound of gaseous and particulate pollutants such as sulfur dioxide, nitrogen oxides and inhalable particulate matter. It is an air pollution phenomenon that has a serious impact on visibility and human health. It will be locked up in museums and history textbooks and become a story that our parents "remember the past".

In the future, no matter how the heating is turned on or how industrial production is run, there is no need to worry about air pollution caused by burning coal for heating or power generation. This is because the power and heat energy in cities are undergoing fundamental changes, and they are continuously coming from natural forces such as sunlight, wind, and rivers.

This is the clean energy era that is coming after we embrace a comprehensive green transformation. A new future where energy no longer relies on coal and oil, but comes from natural and renewable forces.

From the ancient method of drilling wood to modern coal and oil, each energy revolution has greatly affected our production and lifestyle. However, the cost of using traditional energy is also high: air pollution, environmental degradation, global warming, threats to survival...

These challenges have led the world to explore cleaner energy sources, which are not only more environmentally friendly, but also infinitely recyclable. Natural forces such as the sun, wind, and water can be transformed into a continuous supply of green energy through high-tech conversion.

In order to raise public awareness of clean energy and promote the development and application of clean energy worldwide, the United Nations designated January 26 as International Clean Energy Day, calling on the world to work together to achieve the goal of sustainable development.

In my country, advocating green and low-carbon economic and social development is a key link in achieving high-quality development. Promoting low-carbon energy transformation and accelerating the construction and application of clean energy industries are developing rapidly with each passing day.

In the northwest region of my country, Tibet, Xinjiang, Gansu, Qinghai and other places are very rich in solar energy resources, and their solar energy applications are particularly extensive. Photovoltaic panels are arranged in rows to convert sunlight into electricity.

The Delingha photovoltaic thermal power generation base in Qinghai is the first solar thermal power station in the country and the third in the world to be put into commercial operation. It uses tower technology with molten salt as the heat transfer fluid and trough technology with thermal oil as the heat transfer fluid to convert solar energy into thermal energy, and then convert thermal energy into electrical energy, realizing all-weather green electricity supply.

Wind energy also plays an important role in my country's energy strategy, especially in the "Three Norths" region and coastal areas, where thousands of wind turbines stand in windy areas, using the power of every gust of wind to convert into electricity. The construction of offshore wind farms has further improved the efficiency and output of wind power generation, becoming an important way to deliver green electricity to cities and villages.

Hydropower is an important form of clean energy, which uses the potential energy of rivers to convert into electricity. The world-famous Three Gorges Dam uses the torrent of the Yangtze River to provide electricity day and night, demonstrating the huge potential of hydropower. The "clean energy corridor" in the Yangtze River Basin connects multiple large hydropower stations and generates more than 52 billion kilowatt-hours of electricity each year, which is equivalent to saving 15 million tons of coal. This not only improves China's energy security, but also sets a benchmark for the development of clean energy around the world.

Hydrogen energy and nuclear energy are important development directions for future energy. Compared with natural forces, these two energy sources rely more on scientific and technological progress. For example, hydrogen fuel cell vehicles generate electricity through the chemical reaction of hydrogen and oxygen, without the need for oil and pollution-free emissions. They have been tested in many cities such as Wuhan and Shanghai, showing their application potential.

Electricity is generated through the chemical reaction of hydrogen and oxygen, without the need for oil and pollution-free emissions. It has been put into trial operation in many cities such as Wuhan and Shanghai, showing its application potential. At the same time, new applications of nuclear energy, such as the CNNC offshore power generation project, use the warm water discharge area of ​​nuclear power plants to carry out "photovoltaic + nuclear power" multi-energy complementarity, and occupy a leading position in global nuclear energy technology.

In the future, these power stations may no longer be limited to land. Offshore photovoltaic power generation, photovoltaic panels floating on the vast sea like "energy islands", absorb sunlight and convert it into electricity. These floating power plants not only save precious land resources, but also deliver clean energy to coastal cities and remote islands, which is also an important part of the future energy structure.

Clean energy is gradually replacing traditional energy and promoting the comprehensive green transformation of the economy and society. From the widely used solar street lights to the fully electrified city buses and taxis, clean energy is quietly changing industrial production, commercial activities and personal life.

Advocating the use of clean energy is not only an environmental protection action, but has also become a new quality productivity for social development. Green development is the foundation of high-quality development, and the new quality productivity itself is green productivity.

For individuals, understanding and embracing clean energy is not only an environmentally friendly choice, but may also be the healthiest and most economical way of life in the future. At the same time, in response to the national development policy of accelerating the green transformation of economic and social development, the development of clean energy-related industries will also become one of the future trends that attract much attention.
