One Year Down the Road of Biogas Industry Development

Methane is both a powerful energy source and a potent greenhouse gas. When it’s extracted from the earth as natural gas and burned for heating and electricity, it emits carbon dioxide (CO2) but burns more cleanly than some other energy sources such as coal. However, when methane escapes into the atmosphere, it traps 25 times more heat radiation than CO2. That’s why some people are concerned with the environmental consequences of methane leaks during the process of fracking.

Energy Savings Week: How Lighting Standards Are Saving You Money

Lighting accounts for about 11% of home electricity use in the U.S. Home events with family during the holidays can lead to higher utility bills due to increased lighting use. The good news is—even with that extra light—your energy bill can still be reasonable, thanks to efficiency standards the Energy Department has implemented for light bulbs. Lighting standards in place today are projected to save U.S. households almost $7 billion in 2015 alone.
