Natural gas creates carbon dioxide when we burn it to heat buildings and water. But it also leaks methane, an even more potent greenhouse gas, into the atmosphere when it does not make it all the way to our furnaces and water heaters. Older natural gas lines are more likely to leak. Sometimes the leaks get to explosive levels and make the evening news, but on a regular basis there are smaller leaks that emit methane into the atmosphere and contribute to climate change.
You can practically hear the hand-wringing. New England is increasingly dependent on natural gas for electricity generation, and in a long cold winter such as we’ve just experienced, heating need puts a squeeze on this energy feedstock, causing wholesale prices to skyrocket.
