Wind energy is becoming more common form of energy that can be used to run household appliances. a. If a windmill is connected to a hot water tank and is used to heat 60 L ( 60 kg) of water from 15 degrees celsius to 70 degrees celsius. How much energy is required? b. If energy from the utility company costs 0.35 cents per kilojoule, how much per kilojoule, how much money is saved in a year. If the water in the tank is heated 400 times?
