| Estimated U. S. Energy Consumption in 2023: 93.6 Quads |
Found this on Casey Handmer's Blog. Click to embiggenate. A quad is a unit of measurement equal to one quadrillion (10^15) British Thermal Units (BTUs). I suspect that Rejected Energy (the gray box in the upper right corner of the chart) is energy that is converted to heat and dissipated, and Energy Services (the block box in the lower right corner) is energy that was used for useful things. So roughly one third of the 93.6 quadrillion BTUs were used to do something useful, and the other two-thirds was was converted to waste heat. This is a bunch, but it is negligible compared to the zillion BTUs the sun delivers every day.
