1 Renewable Energy

2 Energy Terms Calorie (Cal) The amount of energy needed to raise the temperature of one gram of water one degree Celsius. One calorie equals 4.187 joules or 0.003969 British thermal units (Btu). British thermal unit (Btu) 1. A unit of energy = 252 calories. 2. energy needed to raise T of 1 pound of H2O one degree F. Joule - A unit of energy. One joule equals 0.2388 calories. How many Btu? Watt – Rate of energy conversion. One watt equals one joule of energy per second. – Kilowatt: 1000 – Megawatt: 1,000,000 – Gigawatt: 1,000,000,000 – Terrawatt: 1,000,000,000,000
