Coal-fired power plants emit various pollutants, including sulfur dioxide, nitrogen oxides, and particulate matter, which contribute to air pollution.

Carbon dioxide is the primary greenhouse gas emitted by the burning of fossil fuels, contributing to global warming and climate change.

Selective Catalytic Reduction (SCR) is a technology used to reduce sulfur dioxide emissions by converting them into harmless compounds like nitrogen and water vapor.

Renewable energy sources like solar and wind power do not emit pollutants during electricity generation, thus reducing air pollution.

Sulfur dioxide is a major contributor to acid rain, as it reacts with water vapor in the atmosphere to form sulfuric acid.

Vehicle exhaust is a major source of particulate matter emissions in urban areas, particularly from diesel engines and older vehicles.

Long-term exposure to air pollution has been linked to an increased risk of respiratory and cardiovascular diseases, such as asthma, bronchitis, and heart disease.

Air scrubbing is a process that removes pollutants from the air using various techniques, such as chemical reactions, absorption, or filtration.

Methane is a natural air pollutant emitted by sources such as wetlands, landfills, and livestock.

The photovoltaic effect is the process by which sunlight is converted into electricity using photovoltaic cells.

Hydropower is a renewable energy source that generates electricity from the energy of flowing water without producing greenhouse gases.

Smog is primarily composed of ozone, a reactive gas formed by the interaction of sunlight with nitrogen oxides and volatile organic compounds.

Vehicles emit various air pollutants, including carbon monoxide, nitrogen oxides, and particulate matter.

Carbon Capture and Storage (CCS) is the process of capturing carbon dioxide from industrial sources and storing it underground or in other geological formations.

Industrial activities emit various air pollutants, including sulfur dioxide, nitrogen oxides, and volatile organic compounds.
