Video: More than 8 billion cubic metres of natural gas are lost in the US each year
More than 8 billion cubic metres of natural gas are lost in the US each year, somewhere between the point of production and reaching homes across the nation.
Now, thousands of previously unreported leaks are turning up under the streets of Boston and San Francisco. For the first time, the video shown here reveals methane concentrations on the streets of both cities as much as 15 times higher than the global background level of 1.86 parts per million. The green peaks in the Google Earth fly-around animations indicate areas where gas is leaking from underground.
The map is part of an ongoing effort between researcher Nathan Phillips of Boston University and San Francisco based start-up Picarro to map the exact location and volume of gas emitted from pipeline leaks nationwide. Source New Scientist
