What is meant by energy supply and energy demand?
The quantity of energy supplied is the flow of energy brought onto the market, and the quantity of energy demanded is the amount of energy purchased for a particular period of time .
What is meant by energy demand?
Energy demand is the term used to describe the consumption of energy by human activity . It drives the whole energy system, influencing the total amount of energy used; the location of, and types of fuel used in the energy supply system; and the characteristics of the end use technologies that consume energy.
How do we meet energy demands?
in homes, energy is needed for cooking, to run appliances , and to keep a house warm. in factories and farms, heavy duty machines and production chains are run by the energy supplied to them by the National Grid. transport systems, such as buses, trains, cars and boats use fuel or electricity to run.
