HOW NATURAL GAS WORKS
Natural gas is a versatile fossil fuel that we use for heating, cooking, electricity production, transportation, and as an industrial feedstock. In 2012, it made up 30 percent of the U.S. energy mix, and it continues to be a readily available domestic resource as a result of recent discoveries and advances in extraction technology.

GROUNDWATER & AQUIFERS
Nearly half of the U.S. population relies on groundwater as their primary source of drinking water. In rural areas, this figure approaches 95%. It is easy to see from these figures that groundwater is an importance source of water that should be protected. But what exactly is groundwater?…Learn more>>

…Thanks largely to the hydraulic fracturing boom in the United States, it would be far cheaper today to run those heavy trucks on natural gas than diesel—and potentially cleaner, too. (See related: “Natural Gas Nation: EIA Sees Future Shaped By Fracking.”) Those rumbling rigs are the fastest-growing contributors to the nation’s greenhouse gas emissions from transportation, according to the U.S. Environmental Protection Agency…Read more>>
UNDERSTANDING NATURAL GAS PRICES
Contributor: Hobart King
How Are Natural Gas Prices Determined?–
The price that a buyer pays for natural gas depends upon many factors. Three of the more important factors are: 1) the quantity of gas being purchased, 2) the amount of processing that has been done to prepare the gas for the buyer, and, 3) the amount of transportation required to deliver the gas to the buyer.
