Energy consumption refers to the amount of energy used by individuals, businesses, and industries to perform various activities. This includes electricity for lighting and appliances, fuel for transportation, and energy for heating and cooling. Understanding energy consumption helps in managing resources efficiently and reducing costs. Different sources of energy, such as renewable energy (like solar and wind) and fossil fuels (like coal and oil), contribute to overall energy consumption. Monitoring and reducing energy consumption can lead to lower greenhouse gas emissions, which is essential for combating climate change and promoting a sustainable future.
