Your furnace is one of the most expensive appliances youâll ever buy for your home, due to the intense labor and all of the materials that are necessary for a proper installation.

Critics of the natural gas extraction technique known as fracking have long criticized it for leaking too much methane â a potent greenhouse gas â into the atmosphere during the extraction process.he Environmental Protection Agency recently estimated that natural gas operations emitted about 145 million metric tons of methane in 2011, making it the biggest source of these emissions in the country.
Whether fracking can continue spreading without major harm to the environment or public health, and whether it promises to reduce greenhouse gas emissions, are questions researchers are still working to answer. Fracking is a process for extracting natural gas from shale layers typically thousands of feet deep. These targeted shales arenât especially permeable, meaning most of the gas is trapped. So drillers blast the rock layers with highly pressurized water containing chemicals that reduce friction between water and rock.
