Energy units such as megawatts, kilowatt-hours, tons of oil equivalent, calories and joules are omnipresent in textbooks, the media and, for many, even our every‑day lives. Find out how to make sense of them all in this infographic.
Energy is all around us. To use it optimally, we quantify it and measure its rate of consumption (powerIn physics, power is the amount of energy supplied by a system per unit time. In simpler terms, power can be viewed as energy output...). But consumers, engineers and scientists all use very different units of measurement when talking about energy. This infographic sums up the main units, with a few real-life examples to help you understand the scale.
