Study Notes
Environmental Pollution
- Pollutants from fossil fuel combustion contribute to environmental problems in the US
- Natural gas emits fewer harmful chemicals compared to other fossil fuels, mitigating some issues
- Key environmental issues: Greenhouse gas emissions, smog, air quality problems, and acid rain
Greenhouse Gas Emissions
- Global warming (greenhouse effect) involves increased atmospheric greenhouse gases
- Greenhouse gases (e.g., water vapor, carbon dioxide, methane, nitrogen oxides, chlorofluorocarbons) trap heat near Earth's surface
- Increased greenhouse gases lead to rising global temperatures and significant environmental effects
- Carbon dioxide is a substantial U.S. greenhouse gas emission
- Natural gas combustion emits ~30% less CO2 than oil, and ~45% less than coal
Smog, Air Quality, and Acid Rain
- Smog, primarily ground-level ozone, is a significant air quality problem, particularly in metropolitan areas
- Smog formation involves chemical reactions of carbon monoxide, nitrogen oxides, Volatile Organic Compounds (VOCs) and heat ( sunlight)
- Smog and ground-level ozone lead to respiratory issues, from temporary discomfort to long-term lung damage
- Natural gas emits low levels of nitrogen oxides and negligible particulate matter, reducing smog
- Acid rain damages crops, forests, wildlife, and causes health problems for humans
- Acid rain is created when sulfur dioxide and nitrogen oxides react with water vapor and other elements in sunlight
- Natural gas emits significantly less sulfur dioxide and nitrogen oxides, contributing to lessening acid rain
Pollution from Transportation
- The transportation sector is a primary contributor to air pollution in the US
- Vehicles emit smog, low visibility, and various greenhouse gases
- US vehicles (cars & trucks) account for more than 80% of urban air pollution
- Natural gas vehicles are increasing in use
- Natural gas vehicles offer significant environmental benefits, emitting less harmful pollutants than gasoline and diesel vehicles
- Transit buses account for nearly 62% of the natural gas vehicles on the road, significantly reducing pollution from this sector
