不可再生能源 Non-Renewable Energy
Story and comic created by CCFamily.
There are two types of energy sources: renewable and non-renewable. Non-renewable energy is the energy produced from sources that are limited in supply.
Power plants make electricity by burning "fossil fuels" such as coal, gas, or oil. They can make enormous amounts of electricity but this creates problems too. Burning fossil fuels creates pollution and leads to global warming (the Earth is steadily heating up). Another problem is that the supply of fossil fuels is limited and they are steadily running out.
To solve the problems, we can use renewable and green energy instead.
