What is the primary energy user in the industrial sector?
-
Sorry, that’s incorrect.
A few industries use a very large share of energy in the industrial sector. Petroleum refining is the principal consumer, with the chemical industry a close second. Those users, plus the paper and metal industries, account for 78% of total industrial energy use.

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.

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.

- Distributed Generation
The generation of electricity from a number of small power plants located close to consumers as an alternative to concentrating power generation in large, centralized facilities located in remote areas. This places less stress on transmission lines and reduces the chance of widespread blackouts.
