    Japan is often hit by earthquakes. (L3; earthquake-prone country)

    2. What does Japan have to do now to deal with a potential lack of energy source?

    Japan needs to find a way to maintain a stable energy supply. (L7)

    3. What alternative energy sources are potentially fruitful?
    https://us.sunpower.com/blog/2018/02/23/learn-about-seven-types-renewable-energy/

    1. Solar energy (sun's energy/light→heat→illumination/hot water/electricity/cooling system)
    2. Wind energy (wind→wind turbines→electricity)
    3. Geothermal energy (heat of the earth (e.g. heated rock/hot water underground→geothermal power plants→electricity)
    4. Waterwheels
    5. Power from the ocean (thermal energy/mechanical energy from tides and waves)
    6. Bioenergy (biomass→heat→electricity; biomass→produce liquid fuels (e.g. ethanol/biodiesel)
    7. Hydrogen
