    Study Notes

    Energy Sources

    • Energy sources come from natural resources.
    • Earth's core provides geothermal energy.
    • The sun is the source of solar energy.
    • Solar energy powers the water cycle and enables photosynthesis.
    • Biomass from plants, algae, and cyanobacteria can be used for biofuels.
    • Fossil fuels are formed from buried biomass over millions of years.

    Renewable and Non-Renewable Energy

    • Renewable energy can be replenished within a human lifespan.
    • Examples of renewable energy: solar, wind, and biomass energy.
    • Non-renewable energy is finite and cannot be replenished within a human timescale.
    • Examples of non-renewable energy: nuclear energy and fossil fuels.

    Global Energy Use

    • The distribution of energy sources varies globally.
    • The United States generates less than 10% of its energy from renewable sources.
    • Costa Rica generates more than 99% of its electricity from renewable sources.

    Energy Sources

    • Energy sources come from a variety of natural sources
    • Geothermal energy is generated from the earth's core
    • Tidal energy is generated by the moon and sun's gravitational pull
    • Solar energy is generated from the sun's light (electromagnetic radiation)
    • Solar energy powers the wind, the water cycle, and photosynthesis
    • Biomass energy is created by plants, algae, and cyanobacteria that utilize solar energy to grow
    • Fossil fuels are created from biomass over millions of years through heat and pressure

    Renewable Energy Sources

    • Renewable energy sources can be replenished within human lifespans
    • Examples include solar, wind, and biomass energy

    Non-Renewable Energy Sources

    • Non-renewable energy is finite and cannot be replenished within a human timescale
    • Examples include nuclear energy and fossil fuels
    • Nuclear energy is from uranium, a finite resource.
    • Fossil fuels take millions of years to form.

    Energy Distribution & Costs

    • All energy sources have environmental and health costs.
    • Energy distribution is not evenly distributed among nations.
    • The United States generates less than 10% of its energy from renewable sources.
    • Costa Rica generates more than 99% of its electricity from renewable sources.

    Energy Sources

    • Energy for lighting, heating, cooling, manufacturing and transportation comes from a variety of natural sources.
    • The earth’s core provides geothermal energy.
    • The gravitational pull of the moon and sun create tides.
    • The sun emits light (electromagnetic radiation), which creates wind, powers the water (hydrologic) cycle, and enables photosynthesis.
    • Plants, algae, and cyanobacteria utilize solar energy to grow.
    • Biomass can be burned and used for biofuels, such as wood, biodiesel, bioethanol.
    • Over millions of years, biomass from photosynthetic organisms can create energy-rich fossil fuels through the geologic process of burial and transformation through heat and pressure.
    • Renewable energy sources can be replenished within human lifespans, such as solar, wind, and biomass energy.
    • Non-renewable energy is finite and cannot be replenished within a human timescale, including nuclear energy and fossil fuels, which take millions of years to form.
    • All energy sources have environmental and health costs.
    • The distribution of energy is not equally distributed among all nations.
    • The United States generates less than 10% of its energy from renewable sources.
    • Costa Rica generates more than 99% of its electricity from renewables.
