Why is it better to use solar or wind energy instead of coal?
It is better to use solar or wind energy instead of coal because solar and wind energy are clean energy sources that do not pollute the planet with smoke or waste.
Burning coal creates a lot of smoke and harmful gases that pollute the air, which is not good for our health and the environment.
Solar panels capture sunlight and turn it into electricity, while windmills spin with the wind to make electricity, both without causing pollution.
Explanation
The chapter explains that most electricity comes from burning fuels like coal, which creates smoke and harmful gases that pollute the air. In contrast, electricity generated using natural sources like wind, water or the Sun's energy does not pollute the planet and is called clean energy.
Solution Steps
Solar and wind energy are clean energy sources that do not pollute the planet
Burning coal creates smoke and harmful gases that pollute the air
Coal pollution is harmful to human health and the environment
Solar panels capture sunlight and convert it to electricity without pollution
Windmills use wind to generate electricity without causing pollution
