The results of wind power construction are gratifying. Why do we pay so much attention to energy transformation?

Energy is an important factor in promoting social development. At present, the energy in our lives is mainly electric energy, which is widely used in many fields such as power, lighting, chemistry, and communications. , represents the scientific and technological level of an era, and also directly affects the development of the people's economy. The reason why electric energy can be used so widely is directly related to its characteristics of economy, practicality, cleanness, easy control and conversion. But even so, electric energy still faces environmental problems.

Although electricity itself is a clean energy source, the power generation process is not necessarily environmentally friendly. At present, power generation is mainly based on burning coal. This process is essentially equivalent to converting the internal energy of fossil fuels into electrical energy. Therefore, the power generation process is still accompanied by the production of carbon dioxide, nitrogen oxides, and sulfides. But in fact, with the continuous development of desulfurization and denitrification technology, the main by-product of coal-fired power generation is still carbon dioxide. However, most people also know that the current global carbon dioxide concentration is already at a very high concentration, and this concentration is still rising. Coal-fired power generation is a huge emission port of carbon dioxide. Even if the problems of sulfides and nitrogen oxides are solved, it is still one of the causes of the greenhouse effect.

In addition, the more important point is that the current development of civilization is very dependent on electric energy. Energy transformation in the field of transportation also tends to convert from fuel to electric, so solving the problems in the power generation process Greenhouse gas emissions are of very important value to subsequent environmental protection undertakings.

So how to change? Natural energy has become an important breakthrough. Including wind energy, solar energy, tidal energy, and geothermal energy, many common phenomena in nature are actually accompanied by the release of energy, and "capturing" and converting this energy into electrical energy has become an ideal power generation idea.

In fact, natural energy generation has entered our lives very early. For example, at the beginning of this century, my country began to plan to use photovoltaic power generation as the main power supply method in some areas. One of the goals of this plan is to solve the problem of electricity consumption in remote mountainous areas. In addition, our country established the country's first megawatt-level grid-connected photovoltaic power station in 2004, so solar energy has actually been used by us very early. And that doesn’t take into account other uses of solar energy, such as solar water heaters. The Shilongba Hydropower Station in Kunming City, Yunnan Province was the first hydropower station in my country in 19Construction started in 10 years and was completed in 1912 and official power generation began. Therefore, my country's hydropower industry actually has a history of more than a hundred years.

So why is coal-fired power generation still the main form of power generation? This actually involves many other issues, such as the development of substation systems, limitations of power transmission systems, etc. At present, whether it is tidal energy, wind energy or solar energy, almost all are subject to geographical restrictions. Simply put, the places that can meet the natural energy power generation are actually very far away from the areas with large actual power demand. Therefore, in many cases, natural energy can generate additional electricity. The electrical energy produced cannot be transmitted to where it is needed at low cost. These technical problems in the use of electric energy are also issues that urgently need to be solved on the road to energy transformation. But now, energy transformation has become a very important part of development goals. Technological breakthroughs and the development of innovation capabilities will provide unknown possibilities for economic construction and environmental protection in the future.
