Smoke from coal fires also causes smog
Smoke from coal fires also causes smog. It’s a considerable problem esp. in big cities.
Problem of air pollution should be solved. People should reduce carbon dioxide emitted by power plants and industrial plants. They can reach it by:
• using alternative sources of energy, such as solar (esp.for domestic heating), water, wind, geothermal or tidal energy, or energy coming from methane from landfill waste sites.
• burn smokeless fuels
• energy efficiency in generation of power
• switching from coal to gas fired plants
• using waste heat more efficiently
We should also reduce polution caused by road traffic.
• It’s possible to switch freight from roads to railways
• Public transportation should be supported
• People should be encouraged to drive at speed limit in order to use fuel more efficiently
• New cars should be fitted with three-way catalytic converters in their exhaust system. They turn dangerous gases (nitrogen oxides, hydrocarbons, carbon monoxide) into carbon dioxide, nitrogen and water vapour.
• Content of lead in petrol should be reduced
• People should be encouraged to use unleaded petrol. developed countries use tax relief to favour the use of it
• In order to lower the amount of carbon dioxide, tree planting should be encouraged because they absorb it.
The way how to lower the amount of sulphur dioxide is
• switching from coal to gas for power generation
• greater use of low-sulphur coal
• installation of flue gas desulphurisation plants at power stations
