Study Notes

Energy Sources

Energy sources power our world and are categorized as renewable or non-renewable.
Renewable energy sources are replenished within human lifespans, like solar, wind, and biomass energy.
Non-renewable energy sources are finite and cannot be replenished within a human timescale, such as nuclear energy and fossil fuels.

Non-Renewable Energy Sources

Fossil fuels are formed over millions of years from buried organic matter, transformed by heat and pressure.
Types include petroleum (oil), coal, and natural gas.

Petroleum (Oil)

Accounts for 37% of global energy consumption, used for transportation and manufacturing.
Peak oil is projected to occur by the middle of the 21st century.
Global reserves are estimated at 1.3 trillion barrels, enough for 45 years at current consumption.
Oil refining is a major source of air pollution, releasing volatile organic hydrocarbons and carcinogenic benzene.
Tar sands and oil shale are potential oil sources, but have low net energy values and significant environmental impacts.

Coal

Used for power generation in the United States, responsible for 35% of CO2 emissions in 2010.
Releases sulfur dioxide, nitrogen oxides, and mercury, contributing to acid rain and smog.
Significant social and health impacts include black lung disease, and environmental damage from mountaintop mining.

Natural Gas

Composed primarily of methane, often considered a cleaner fossil fuel option, but still has environmental impacts.
Fracking, a high-pressure extraction technique, raises concerns about water contamination and chemical usage.

Renewable Energy Sources

Hydropower provides 25% of U.S. renewable energy consumption, but can have environmental impacts on aquatic habitats.
Biofuels like ethanol and biodiesel are alternatives to fossil fuels but come with social and economic concerns, such as land use competition for food production.
Geothermal energy harnesses heat from the Earth, offering low-emission energy production.
Solar energy converts sunlight into electricity, but manufacturing solar panels has environmental impacts.
Wind energy offers clean energy generation with minimal environmental impact, aside from potential impacts on birds and bats.

Air Pollution

Air pollution can be categorized as primary pollutants (directly emitted) and secondary pollutants (formed from reactions in the atmosphere).
Six major air pollutants are harmful to human health: carbon monoxide, sulfur dioxide, nitrogen oxides, volatile organic compounds, particulate matter, and ozone.
Carbon monoxide reduces oxygen delivery to organs, sulfur dioxide contributes to acid rain, nitrogen oxides form smog, and particulate matter impacts respiratory health.
Ozone is a key component of smog and can damage human health and vegetation.
