HANGZHOU, Jan. 24 (Xinhua) -- East China's Zhejiang Province launched over 3,700 "electricity replacement projects" in 2018, leading to a sharp reduction of carbon dioxide emission, the State Grid Zhejiang Electric Power Co. Ltd. said Thursday.

A total of 3,714 replacement projects were launched in the province last year, which resulted in the consumption of over 7 billion kilowatt hours of electricity to reduce the consumption of coal and oil equivalent to 2.8 million tons of standard coal, the company said.

The company has been promoting electric power in major fields over the past few years, instead of using coal and oil, so as to slash air pollution and haze.

The major fields cover transportation, residential consumption and industries including tourism, manufacturing industry and agriculture.

So far, 71 tourist attractions in Zhejiang rely entirely on electricity for energy supply. More than 25,000 households in the province have used electricity for heating.
