This brief analysis examines the relative cost of the energy from milk and gasoline. The unifying approach involves the use of a common measure of energy—British thermal units (Btu). A cup of whole milk contains 150 Calories of energy. Therefore, the cost of 1,000 Btu from conventional whole milk was $0.37.

Renewable energy sources are central to the energy transition toward a more sustainable future. However, because sunshine and wind are inherently variable and inconsistent, finding ways to store energy in an accessible and efficient way is crucial. An open-access paper on the work is published in the journal Energies.

times the energy and environmental impacts per passenger than the usual route. When these two ratios are combined, the result is that (if fully occupied), the current route uses 9.2 times the fuel per passenger compared with the usual route (1.4 * 6.6 = 9.2). Thus, the current route has about 9.2

This analysis compares the costs of usable energy when we buy gasoline and electricity for driving and natural gas for keeping warm. Combustion of a gallon of gasoline (that includes ethanol) releases 120,333 Btu of energy. The average retail cost of regular gasoline in 2018 was $2.719 per gallon. by Michael Sivak.
