    • Update on lignite firing

    lignite is its environmental impact. These days, proposals to build coal-fired power plants are often strongly opposed by local residents and non-government organisations (NGO) because of concerns over the impact of coal combustion on the environment and climate change. Using lignite as a fuel for power generation has several disadvantages.
