Energy Consumption in the Food Industry

The food industry in the USA consumed 17 billion calories in 1999. Electricity is the main source of energy costs for the food industry. The industry buys 64.0 billion kWh of electricity each year at a cost of $3.36 billion.

The food industry has a 1.3% purchase energy rate compared to the total US industry's 1.7%. Electricity is used in a number of ways, including freezer and refrigeration compressors, conveyor, air handling, pumping, lighting, process controllers and monitors, and packaging forming and seal. Relative costs are the main reason for the use of natural gas the primary source of thermal energy for ovens, fryers, dryers, and boilers.

Crop irrigation, pest control, produce disinfection, grain harvesting and storage, weed reduction, livestock waste management, and fish farming are all related to electricity used in agricultural food production. Food energy costs have gone up over the past two decades. In 1996, electricity made up half of the total energy used.

The total food industry use of electricity is 23, 19, and 13%, with grain milling, meat processing, preserved fruits and vegetables accounting for 23, 19, and 13%. Almost all of the electricity used by the food industry in the USA is purchased from utility companies, even though some food processor cogeneration facilities use surplus heat to produce electricity. Motor-driven equipment such as compressors, pumps, mixers, grinders, fans, and so on use about 85% of the electricity.

What to Eat When You're Away

Food companies calculate the nutrition labels on packaged foods. The scientists at the company find out the mass of the food. They calculate the energy values using the values listed above.

Energy of the Human Body

The human body uses a wide range of energy, with 20% of it used for brain metabolism and the rest used for other organs and tissues. In cold environments, metabolism increases to produce heat. One of the uses for energy is the production of mechanical energy by the muscles of the body.

Oats: A Natural Alternative to the Standard Diet

34% of the recommended daily amount is found in one serving of oatmeal. What is the recommended amount of fiber? To the nearest whole number, round.

Inflationary headlines

The headline number in news reports is usually the Consumer Price Index. The Bureau of Labor Statistics runs the Consumer Price index, which measures more than 200 categories of items grouped into eight major groups. Health care and medical costs are included in both core and overall measures of inflation.

Calculation of UME figures in the intestine

The calculation of UME figures is very easy. The total milk output is documented. The calculation of beef and sheep enterprises is more complex than it is for other businesses because the total annual liveweight gains are more difficult to obtain and are subject to more error.


A calorimeter is a device that can measure the energy of food. You put the food in a calorimeter. You put the calorimeter in a quantity of water.

You can measure the increase in temperature of the water by burning food. By taking careful measures, one can determine the amount of energy required to heat the water. It isn't so far off as it might appear.

A gallon of gas will help the car to speed and keep it there for 30 miles. The gas has energy from bonds of chemical substances. The bonds in gas are not completely different from the bonds in a hamburger.

132,000 BTU is the amount of gas that can be burned. That is more than the amount of J that can be burned from a hamburger. It sounds like gas has more energy per pound.

A hamburger has enough energy to run a car for 0.2 miles. If $F$ is small, $Delta x$ will be large. It just takes a long time for a human to get a car up to speed.
