Dual energy X-ray absorptiometry (DXA) is a technology that can specifically measure for fat content, resulting in a more accurate assessment of total body fat levels, he explained.
When you eat food, you are consuming energy stored in a chemical form, the amount of which can be measured by the caloric content (read the Calories Explained article) of whatever you are eating.
A gallon of ethanol has a lower energy content than a gallon of gasoline (as measured by BTU content).
For a long time now climatologists have been tracking the global average air temperature as a measure of planetary climate variability and trends, even though this metric reflects just a tiny fraction of Earth's net energy or heat content.
The key points of the paper are that: i) model simulations with 20th century forcings are able to match the surface air temperature record, ii) they also match the measured changes of ocean heat content over the last decade, iii) the implied planetary imbalance (the amount of excess energy the Earth is currently absorbing) which is roughly equal to the ocean heat uptake, is significant and growing, and iv) this implies both that there is significant heating «in the pipeline», and that there is an important lag in the climate's full response to changes in the forcing.
Higher Heating Value: A measure of heat content based on the gross energy content of a combustible fuel.

Global coal consumption, which is measured in in tonnes of coal equivalent — the industry standard to reflect energy content rather than physical weight — will reach 6.2 billion tonnes in 2017, up from 5.3 billion in 2011.
Satellites have the virtue of measuring total energy content of the troposphere with a near global coverage.
If you actually had a meter that measured energy content of storms, that would be the way to go.
(The efficiency of a power plant is measured as the percentage of the total energy content of that plant's fuel that is converted into electricity.)
Transportation measures generally contribute a higher percentage to emissions reductions than to energy use reductions due to the relatively high carbon content of most transportation fuels.
Regarding the real world earth and the real world atmosphere — granted that the temperature measures different things for different objects, but in all cases there is a proportionality constant between the (change in) thermal energy content of an object and its (change in) temperature, and that is the heat capacity.
This is a large part of the atmospheric energy content and it is not measured by thermometers.
The rate of warming as measured by ocean heat content changes over the last 4 years shows that we have DOUBLED the top - of - atmosphere energy imbalance from 0.6 watts per meter squared to 1.1 watts per meter squared in the last 7 years.
At that point you try and measure changes in heat content of the upper ocean, more precisely, the flow of energy into and out of the upper ocean by measuring the change in heat content over time.
The more direct measure of global warming provided by measuring the energy content of the climate system avoids many of these problems, although the observational record is shorter and less complete (e.g. Church et al 2011).
As you say, the total energy content of the climate is a more direct measure of global warming.
Heuristically, the gross moist stability is the difference in energy content between the air flowing out of the ITCZ in the upper branch of the Hadley cell and the air flowing into the ITCZ near the surface; it is also a measure of the efficiency of the Hadley cell in moving energy.
If we could land a man on the moon, why can't we measure the damn ocean heat content, before turning over control of the global energy economy to R. Gates, fan and Jim D?
All that is needed is to add heat carried upwards past the denser atmosphere (and most CO2) by convection and the latent heat from water changing state (the majority of heat transport to the tropopause), the albedo effects of clouds, the inability of long wave «downwelling» (the blue balls) to warm water that makes up 2 / 3rds of the Earth's surface, and that due to huge differences in enthalpy dry air takes far less energy to warm than humid air so temperature is not a measure of atmospheric heat content.
His proposed broad - based energy tax would apply to the energy content of nearly all fuels, as measured by the British thermal unit, or B.T.U. — the quantity of heat needed to raise the temperature of a pound of water by 1 degree Fahrenheit.
