Energy is a major component of the economy of Texas. The state is the nation's largest energy producer, producing twice as much energy as Florida , the state with the second-highest production. It is also the national leader in wind power generation, comprising about 28% of national wind powered electrical production in 2019.
The calorie is a unit of energy that originated from the caloric theory of heat. [ 1 ] [ 2 ] The large calorie , food calorie , dietary calorie , or kilogram calorie is defined as the amount of heat needed to raise the temperature of one liter of water by one degree Celsius (or one kelvin ).
The caloric theory is an obsolete scientific theory that heat consists of a self-repellent fluid called caloric that flows from hotter bodies to colder bodies. Caloric was also thought of as a weightless gas that could pass in and out of pores in solids and liquids.
