Category Description: Energy & Fuels covers resources on the development, production, use, application, conversion, and management of nonrenewable (combustible) fuels (such as wood, coal, petroleum, and gas) and renewable energy sources (solar, wind, biomass, geothermal, hydro

WHAT IS AN IMPACT FACTOR?
The journal impact factor is a measure of the frequency with which the average article in a journal has been cited in a particular year. The impact factor helps you evaluate a journal's relative importance, especially when you compare it to others in the same field. The impact factor is calculated by dividing the number of citations in the current year to items published in the two previous years by the total number of items published in the two previous years.

Using Journal X as an example:
Cites in 2011 to items published in: 2010
2009
Sum
= 258
= 199
= 457
Number of items published in: 2010
2009
Sum
= 116
= 71
= 187
Calculation: Cites to recent items 457 = 2.444
Number of recent items 187

The 2011 Impact Factor for Journal X is 2.444
