Calorie (Nutritional)
A calorie (Cal) is a unit of energy used to measure the amount of energy provided by food and beverages, specifically representing the amount of energy needed to raise the temperature of one kilogram of water by one degree Celsius.
History/Origin
The calorie was first introduced in the 19th century as a unit to quantify energy in nutrition. It has since become a standard measure in dietary and nutritional contexts, although the scientific community often prefers the joule as the SI unit of energy.
Current Use
Calories are widely used in nutrition to quantify the energy content of food and beverages, helping consumers manage dietary intake and energy balance. The term 'Calorie' with a capital 'C' typically refers to kilocalories (kcal), which are equivalent to 1,000 small calories.
Gigawatt-Hour
A gigawatt-hour (GW·h) is a unit of energy equal to one billion watt-hours, representing the amount of energy produced or consumed over one hour at a power level of one gigawatt.
History/Origin
The gigawatt-hour emerged as a standard unit of energy measurement in the 20th century with the development of large-scale power generation and electrical engineering, facilitating the quantification of energy production and consumption in power plants and grids.
Current Use
Gigawatt-hours are used today to measure large-scale energy production, consumption, and capacity in power systems, renewable energy projects, and national energy statistics, aiding in energy management and planning.
