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.

On average, which is most efficient in coverting heat into electic power?
- Coal boiler power plant
- Natural gas-fired turbine power plant
- Natural gas combined-cycle power plant
-
Sorry, that’s incorrect.
On average, a typical coal-burning power plant in 2013 was about 33% efficient in converting heat energy into electrical power. A gas-fired plant was about 42% efficient. And in natural gas combined-cycle power plants—in which waste heat from a natural gas turbine is used to power a steam turbine—generation may be as much as 60% efficient.

True or false? Hydraulic fracturing and horizontal drilling have increased oil and gas production in the U.S.
-
Correct!
Extraction of "tight" oil—light crude oil contained in geological formations of shale or sandstone—accounted for only 12% of total U.S. oil production in 2008. By 2012, it made up 35%, and is predicted to rise to 50% in the near term.

- Climate Change
The process of shifting from one prevailing state in regional or global climate to another. Often used interchangeably with “global warming,” scientists sometimes also use the term to refer to periods of climatic cooling. Climate change is typically the preferred term over “global warming” because it helps convey that there are climate changes in addition to rising temperatures.
