If the US energy consumption is 100QBTUs and a quad is 10^15BTU, how many 1500watt hairdryers...?

Question

would it take each person to consume their share of energy (joules per second)?

Answer 1

1500 watts is about equal to 5,000BTU per hour so if you figure 6 billion people use hair driers they would use 30 trillion BTUs per hour. Now, a quad is 1000 trillion BTUs so doing the math: 1000x100/30 gives ~3,300 hours. But, if only one billion people use hair driers thats wrong-go figure.

Answer 2

About what WalMart sells in a day...

Answer 3

That is the main reason I never wash my hair.

So subtract me from the value of (each person)

Answer 4

About 7.3 hair dryers per person running 24 hours per day, 365.25 days per year.

The US energy consumption is 100QBTUs per year. Convert that to joules per second. Consumption is 3.343 X 10^12 J/s.

Divide that by population. I used 304,550,000 people. That is 10,977 J/s per person. Divide that by 1500 J/s per hair dryer.

Answer 5

current electricity usage is about 200  100-watt light bulbs per person in the US.

20000 watts / 1500 watts is about 13 hair dryers. kind of silly to think in hair dryers, light bulbs is easier to picture.

20,000 watts is enough to incinerate someone
