What You Need To Know About Energy
What do you know about energy?
Energy intensity is a measure of:
- The amount of energy used by a nation per unit of GDP
- The amount of energy contained in a given amount of fuel
- The amount of electric current passing through a point
-
Correct!
Energy intensity is a measure of a nation's energy efficiency represented through energy use per unit of GDP (Gross Domestic Product).
-
Sorry, that’s incorrect.

Which has been growing more, energy used by lighting and appliances or energy used for heating and cooling?
-
Correct!
For decades, more than half of all residential energy use went to space heating and cooling; in 1993, it accounted for nearly 60%. But EIA data show that by 2009, that share had dropped to 48%. And in the period 1993 to 2009, energy for appliances, electronics, and lighting rose from 24% to 35%, owing to the proliferation of appliances, as well as trends toward larger TVs and other devices.

A typical incandescent lamp (traditional light bulb) consumes 60 watts of power. How much do each of a compact fluorescent and LED lamp consume, in watts, to produce the same amount of light?
-
Sorry, that’s incorrect.
A typical incandescent lamp (traditional light bulb) that consumes 60 watts of power produces around 800 lumens. A compact fluorescent lamp emits the same amount of light while using only 13 watts. And an LED lamp consumes only 10 watts to give off the same 800 lumens.
