Tongwei Group Liu Hanyuan: Accelerating the development of photovoltaic industry

It is necessary to seize the opportunity and seize the commanding heights of the global new round of economic development of the solar photovoltaic industry. In Liu Hanyuan's view, the photovoltaic industry will become the biggest engine of global economic development with its huge development space and market scale, and will also promote China to take the lead in the era of clean energy. He believes that if 1% of the northwestern part of China's most abundant solar thermal resources is used, energy development of 5 billion tons to 6.25 billion tons of standard coal can be achieved, equivalent to about twice the current energy use in China. He believes that China is currently at an important development critical point. Energy security issues are urgently needed.
