Light Bulb Ban Produces Hoarding In EU, FUD In U.S.

Lucas123 writes "The very thought of losing that pear-shaped giver of warm, yellow light drove Europeans to hoard Edison's invention [Note: Or possibly Joseph Swan's invention; HT to eldavojohn.] as the EU's Sept. 1 ban on incandescent light bulbs approached. China's ban on incandescent lamps starts Oct. 1. And, in the U.S., the Energy Independence and Security Act (EISA) of 2007 effectively began banning the 100W bulb this year and will ban the most popular bulbs — the 75W, 60W and 40W screw-in incandescent bulbs --over the next two years. The end standard requires bulbs to use 65% less energy by 2020. But Republicans in Congress continue to fight the ban by hamstringing the energy efficiency standards through appropriations legislation, cutting off funds for the enforcement of the light bulb ban."

Re:All Edison's fault

I understand what a heat pump is and does.

It's wired to a home's electrical wiring.

It draws X amount of current at Y amount of voltage. There are different ways to look at the product of these two, but this is called wattage.

The transducer, which is the heating element, draws power, then converts that to heat. That's one circuit. Let's focus on that circuit, because that's where we derive the efficiency value from.

The power in watts in to the transducer in a heat pump will be less than the heat value radiated. It's always less than 100%. Good ones approach 96%. Poor ones are at around 85-90%. One cannot add more heat to the element, but there are dispersion designs that allow higher and higher efficiency, and there are methods consider the atmospheric pressure, relative humidity, gaseous composition of the airflow around the heat pump transducer element, and so forth. But at the end of the measurement, it's less than 100%.
