Air Quality + Fossil Fuels

Energy Generation Process

The method of generating electricity by burning fuel to create heat, which produces steam that drives a turbine connected to a generator.

Inverter

A device that converts alternating current (AC) to direct current (DC), commonly used in charging blocks.

Power Plant

A facility that generates electricity, typically producing direct current (DC) that is converted to alternating current (AC) for distribution.

Solar Power

A renewable energy source that generates electricity through the movement of electrons caused by photons, without the combustion process.

Clean Air Composition

The primary gases found in clean air, including nitrogen (70%), oxygen (21%), and trace gases (1% argon, 0.044% CO2).

Pollutants from Fossil Fuels

Harmful substances released from burning fossil fuels, including carbon dioxide, carbon monoxide, mercury, particulate matter, and volatile organic compounds (VOCs).

Effects of Pollutants

The impact of air pollutants on the environment and human health, leading to issues like acid rain, smog, and respiratory problems such as asthma.

Troposphere

The lowest layer of the atmosphere where weather occurs and where humans live, characterized by decreasing temperatures with altitude.

Thermal Inversion

A phenomenon where warm air traps cooler air in valleys, preventing pollution from dissipating.

Anthropogenic Pollution

Pollution that is primarily caused by human activities, such as the combustion of gasoline.

Primary Pollutant

A pollutant that is directly emitted from a source, such as carbon monoxide from gasoline combustion.

Secondary Pollutant

A pollutant that forms when primary pollutants react with other substances in the atmosphere, such as tropospheric ozone.

Complete Combustion

A process that produces carbon dioxide as a byproduct, contributing to greenhouse gas emissions.

Incomplete Combustion

A process that occurs with limited oxygen, producing carbon monoxide, which can interfere with red blood cell function.

Acid Rain

Rain that has been acidified by pollutants like sulfur dioxide and nitrogen oxides, leading to environmental damage.

Industrial Smog

Air pollution resulting from burning coal, characterized by the presence of pollutants like carbon dioxide, nitrogen, and sulfur dioxides.

Photochemical Smog

Air pollution that occurs when sunlight catalyzes reactions with pollutants, resulting in brown air smog and tropospheric ozone.

Ground Level Ozone

A harmful air pollutant that can cause respiratory issues, including burning sensations when inhaled.

Clean Air Act (1970)

Legislation that established the EPA's authority to limit emissions and set air quality standards.

Criteria Air Pollutants

Specific pollutants regulated by the EPA, including carbon monoxide, nitrogen dioxide, sulfur dioxide, particulate matter, and lead.

Air Pollution Reduction Methods

Strategies to reduce air pollution, including the use of scrubbers, catalytic converters, and vapor recovery nozzles.

Conservation Efforts

Actions to reduce resource use, such as driving less and using energy-efficient appliances to lower air pollution.

Alternative Fuels

Renewable energy sources like electric vehicles, hydrogen-fueled vehicles, and biofuels derived from biomass or plants.
