    Renewable Energy Limitations

    Renewable energy can be expensive, unreliable, and not universally applicable in developing nations.

    Nuclear Power Characteristics

    Nuclear power is often considered renewable but uses a non-renewable resource, uranium, posing safety concerns.

    Nuclear Reactor Function

    Nuclear reactors generate heat through uranium fission to drive turbines for electricity production.

    Nuclear Power Pros and Cons

    Nuclear power is reliable and clean post-construction, but has risks like radioactive waste.

    Study Notes

    Energy Sources

    • Non-renewable energy sources, also known as fossil fuels, are not sustainable.
    • They take a long time to form from dead organisms.
    • Fossil fuels will eventually run out.
    • Non-renewables currently provide a large proportion of the world's energy.

    Renewable Energy Sources

    • Renewable energy sources can be replenished.
    • They are obtained from natural resources like the sun, wind, or water.
    • Examples include hydroelectric power, wind power, solar power, biofuels, and wave/tidal power.
    • Using biofuels like fuelwood is renewable if the trees are reforested.

    Differences in Energy Sources Between Countries

    • Developed countries use more energy per capita.
    • Their energy sources differ from developing countries.
    • Developing countries rely more on resources concentrated in developed areas.

    Why Countries Rely Less on Non-Renewables

    • Non-renewable resources are not sustainable and will eventually run out.
    • Global warming pressures nations to switch because fossil fuels contribute significantly to atmospheric pollution.
    • Countries want to reduce reliance on imports.

    Why Only Few Countries Use Renewable Energy

    • Renewable energy is still in the early stages of development.
    • Developing countries often cannot meet all their energy demands.
    • Setting up renewable energy infrastructure is expensive.
    • Renewable energy sources are sometimes unreliable.
    • Renewable energy sources can be inefficient compared to non-renewable alternatives.

    Nuclear Power

    • Nuclear power is considered a unique energy source; it is a renewable energy source that uses uranium.
    • Uranium is a non-renewable resource.
    • Nuclear power can be controversial due to potential catastrophic disasters.

    How a Nuclear Reactor Works

    • Nuclear reactors, despite different designs, share similar basics.
    • They use uranium and nuclear fission to generate heat.
    • The heat drives turbines to generate electricity.

    Benefits and Disadvantages of Nuclear Power

    • Building nuclear power plants is expensive but once built, they are reliable and cheap, and clean and safe.
    • Nuclear waste needs safe disposal, which poses a risk to the environment due to radioactivity for hundreds of years.
    • Nuclear power plants create jobs for many people.
    • Nuclear plants can be built in remote areas to reduce dangers to health.
    • Most countries need to import uranium for their nuclear power plants.

    Siting of Power Stations

    • Most power stations need to be near bodies of water for cooling steam.
    • They usually need to be relatively close to urban areas for a workforce.
