• For running all of this energy is required which is obtained by burning fossil fuels, natural gas etc.
• The smoke from this releases a large amount of CO2 which gets accumulated in the atmosphere.
• CO2 is a greenhouse gas and it increases the amount of the greenhouse effect. This increases the average temperature of the Earth.
