A natural gas company in Great Falls, Mont., wanted to educate consumers. So it printed up 25,000 scratch-and-sniff cards to show how a gas leak would smell. Then yesterday, the company tossed some of the cards. And as they were crushed in a garbage truck, the gas smell filled the town.
Several buildings were evacuated after people reported gas leaks. The company apologized, but said that their campaign, in a sense, worked.
The new boom in natural gas from shale has changed the energy economy of the United States. But there's another giant reservoir of natural gas that lies under the ocean floor that, theoretically, could dwarf the shale boom.
No one had tapped this gas from the seabed until this week, when Japanese engineers pulled some up through a well from under the Pacific. The gas at issue here is called methane hydrate. Methane is natural gas; hydrate means there's water in it. In this case, the molecules of gas are trapped inside a sort of cage of water molecules.
The way Americans get their electricity is changing. Coal is in decline. Natural gas is bursting out of the ground in record amounts. And the use of wind and solar energy is growing fast. All this is happening as power companies are trying to choose which kind of energy to bet on for the next several decades.
Until recently, half of these plants burned coal to make electricity. Now, that's down to about one-third. Since 2010, about 150 coal plants either have been retired or it's been announced they will be retired soon.
"It sounded like thunder, but it felt like an earthquake," Tracey Truitt, a lawyer who was working in a nearby building, tells the Kansas City Star about an explosion Tuesday evening that leveled a restaurant in the city's Country Club Plaza.
At least 16 people were injured and as of early this morning one person remained missing, the Star says.
