Air pollution from coal-fired power plants is linked with asthma, cancer, heart and lung ailments, neurological problems, acid rain, global warming, and other severe environmental and public health impacts.
Coal provides 30% of global primary energy. It is used to generate 41% of global electricity. It is also used to produce 68% of the world's steel and is a key source of energy in energy-intensive industries, such as aluminum and cement production.
Steel production has a number of impacts on the environment, including air emissions (CO, SOx, NOx, PM2), wastewater contaminants, hazardous wastes, and solid wastes. The major environmental impacts from integrated steel mills are from coking and iron-making.
Steel is sturdy enough that it resists the damage caused by natural disasters, such as tornadoes, hurricanes, and earthquakes. Steel buildings are much more resistant to fire and termites. Because of steel's greater durability, the owner of such a building could get a better deal on insurance.
