Conventional and Non-Conventional Sources of Energy | Why Are Non-Conventional Sources of Energy Important?
Energy is the capacity for doing work, generating heat and emitting light. It is measured as the total amount of work that the body can do. Energy is measured in units of caloric and joule. A kilocalorie is the amount of energy or heat required to raise the temperature of 1 kg of water from 14.5°C to 15.5°C. The joule is defined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter.
