The annual fuel utilization efficiency (AFUE; pronounced 'A'-'Few' or 'A'-'F'-'U'-'E') is a thermal efficiency measure of space-heating furnaces and boilers.The AFUE differs from the true 'thermal efficiency' in that it is not a steady-state, peak measure of conversion efficiency, but instead attempts to represent the actual, season-long, average efficiency of that piece of equipment ...
For energy-conversion heating devices their peak steady-state thermal efficiency is often stated, e.g., 'this furnace is 90% efficient', but a more detailed measure of seasonal energy effectiveness is the annual fuel use efficiency (AFUE). [10]
In 2004, a consortium of major auto-makers — BMW, General Motors, Honda, Toyota and Volkswagen/Audi — came up with "Top Tier Detergent Gasoline Standard" to gasoline brands in the US and Canada that meet their minimum standards for detergent content [17] and do not contain metallic additives.
The US auto sector is still finding its footing after a pandemic-era boom. The incoming Trump administration may add to this uncertainty. Major US automakers like GM and Ford spent 2024 curtailing ...

A Washington, D.C. man has been charged with murder after police say he stabbed his grandmother to death and then texted a photograph of her dead body to other family members last Friday.
AFUE = furnace efficiency ≈ 95% for a modern condensing furnace; COP = heat pump coefficient of performance ≈ 3.2 seasonally adjusted for northern US heat pump; EI = emissions intensity of electricity ≈ 200–800 ton(CO 2)/GWh, depending on the region's mix of electric power plants (Coal vs Natural Gas vs Nuclear, Hydro, Wind & Solar)
Even if you live in a state that doesn’t require insurance, car accidents are common, it's worth making sure you're protected against the high costs that come with an emergency. This insurance ...
