Electricity Production Background
Electricity comes from primary energy. Primary energy can be divided into two categories according to whether it is renewable:
⑴ Non-renewable energy. Refers to natural energy that cannot be reproduced. It is becoming less and less with human use, such as fossil energy (such as coal, oil, natural gas) and nuclear fuel (such as uranium, thorium, etc.).
⑵ Renewable energy. Refers to the natural energy that can be produced repeatedly, that is, it will not decrease with its own transformation or human use, such as solar energy, hydropower, wind energy, geothermal energy, ocean energy, biomass energy, tidal energy, etc.
