Final answer:
If non-renewable resources like coal, oil, and gas get exhausted, we would use other forms of renewable energy such as solar, wind, nuclear, and hydroelectric energy. Each has its own pros and cons, and the usage would likely depend on factors like location and technology.
Step-by-step explanation:
If all non-renewable energy sources like coal, oil, and gas get exhausted, we will need to rely on other forms of energy. The alternatives indicated in the question are all possible solutions, as they are all forms of renewable energy.
Solar energy is captured from the Sun, which provides the Earth with much more energy than we need daily. Wind energy is generated from the kinetic energy of wind converted into electricity. Nuclear energy comes from nuclear reactions where a small amount of mass is converted into a large amount of energy. Lastly, hydroelectric energy is produced from the movement of water in rivers and ocean tides.
Each of these alternative energy sources has its own benefits and drawbacks, and the usage of each one would likely depend on a variety of factors such as geographical location and technological advancement.
