    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.
