By Joe Kiesecker, Scientist for Lands Conservation, The Nature Conservancy Note: this article is the first in a series on “energy sprawl,” the conversion of new land for energy production. It is because these areas experienced large-scale economic development, there original energy sources were fossil fuels – first coal and the oil and gas. ” refers to the combination of the various primary energy All energy sources that have not undergone any conversion process and remain in their natural state.. sources used to meet energy needs in a given geographic region. STUDY. “Affect” vs. “Effect”: Use The Correct Word Every Time. PLAY. In solid-state physics, a band gap, also called an energy gap, is an energy range in a solid where no electronic states can exist.
