Aim at the market and create greater glories
With the depletion of fossil fuels and the increasing environmental problems caused by them, nuclear power is widely recognized for its clean, high-efficiency characteristics of not emitting fumes, sulfur dioxide, and carbon dioxide. At present, the world’s annual nuclear power generation is equivalent to reducing emissions. The greenhouse gas is 3 billion tons. It has been proved that each million-ton nuclear power station built in Tianwan No. 3 unit can replace 2.8 million tons of standard coal annually. Because nuclear power has green emissions, the site selection is flexible, the capacity is large, and the efficiency is high. With its low economic cost and high return on investment, it has become an important part of the energy structure of major industrial countries in the world. Nuclear power development is still one of the important choices for countries to guarantee future energy supply. There are 18 nuclear power companies in the world. Both have exceeded 20%, and the average level in the world is about 13%. At present, nuclear power accounts for only 2% of China's power structure. The development space is huge. Development of nuclear power to China breaks through the bottleneck of resources and environment, and realizes green and low-carbon development. Beautiful China' has an irreplaceable role.
While restructuring and upgrading the national energy industry structure and deepening supply-side structural reforms, Harbin Electric Power actively responds to national policies, accelerates adjustments to diversified industries, aims at markets, and seizes opportunities.
