The correct answer is "false".
In the given problem, the light bulbs in an office building gives off tremendous amounts of heat. Heat is a form of the energy. This could be trapped and used to offset our need for electricity.
The electrical energy is converted into light energy and heat energy. There is dissipation of the electrical energy in the form of heat energy. In this way, electrical energy is wasted in the form of heat energy. There is no saving of energy and money. There is more consumption of the electrical energy. People have to pay huge amount of electricity bill.
Therefore, the given statement is false.
The answer is true.
An example of harnessing this is the bulb could be used to warm up the office during, the cold seasons such as during winter, hence negate the necessity for buying a heater which would cost more. The heat could also be harnessed to warm water for office use.
