HPAC Quiz – Feb/March 2023

Perhaps the word heard most often at AHR Expo in Atlanta this month was “electrification,” which many manufacturers now see as our industry’s best strategy for achieving net zero carbon emissions. With that in mind, we dive into the short but revolutionary history of electrification.
1. In 1831-1832, this inventor discovered the operating principle of electromagnetic generators and became the first to build one. What was his name?

A. Benjamin Franklin

C. Thomas Edison
D. George Westinghouse

2. Thomas Edison is often thought to have invented the first incandescent light bulb, but in 1879, he was only the first to introduce it in the U.S. A year prior, in Britain, this inventor developed an earlier bulb that used a carbon filament sealed in a high vacuum. Edison’s ultimately proved more successful because it used a thinner filament, giving it higher resistance. Who was the earlier inventor?
A. Elihu Thomson

B. Lord Kelvin

C. Nikola Tesla

3. The first AC power station was designed and built by British electrical engineer Sebastian de Farranti for the London Electric Supply Corp. The facility pioneered the use of high voltage (10,000 V) AC current and generated 800 kilowatts to supply central London upon its completion. What was the year?

A. 1884

B. 1888

4. During the Great Depression, one of the most ambitious and successful New Deal programs was the Rural Electrification Administration (REA), which provided federal loans for the installation of electrical distribution systems. By 1942, 50% of U.S. farms had electricity. A decade later, roughly all did. What year did Franklin Roosevelt create the REA via executive order?
A. 1933
B. 1934

5. Today, the International Energy Agency (IEA) is promoting electrification as a key sustainable solution to meet global energy demand. IEA estimates that ground source heat pumps could provide as much as 90% of the world’s space and water heating requirements, which would greatly reduce total annual energy loads associated with heating and cooling. What percentage does IEA estimate is currently provided globally by such heat pumps?
{{CorrectAnswer05}}
B. 10%
C. 20%

D. 34%
