    • Tidal

    • Wind

    • Ocean current

    • Uranium

    Correct Answer
    A. Uranium
    Explanation
    Uranium is a non-renewable energy source because it is a finite resource and cannot be replenished naturally within a human lifetime. Once uranium is extracted and used as fuel in nuclear reactors, it cannot be reused or regenerated. In contrast, tidal, wind, and ocean current energy are considered renewable sources as they rely on natural processes that are constantly replenished, such as the movement of tides, wind patterns, and ocean currents.

    • It reduces the standard of living

    • Unintended environmental consequences result

    • It is not cost effective for our economy

    Correct Answer(s)
    A. The fossil fuel resource is limited in amount and it will be used up soon
    A. Unintended environmental consequences result
    Explanation
    Depending on fossil fuels for most of our energy creates two major problems. Firstly, the fossil fuel resource is limited in amount and will eventually be depleted. This means that once we exhaust these resources, we will no longer have access to them for energy production. Secondly, depending on fossil fuels leads to unintended environmental consequences. The extraction, production, and burning of fossil fuels release greenhouse gases and contribute to climate change, air pollution, and other environmental issues. These consequences have detrimental effects on ecosystems, human health, and the overall sustainability of our planet.
