A report released by Boston Consulting Group reveals that natural gas is saving US households between $425 and $725. Practices such as hydraulic fracturing have allowed the access of natural gas that formerly was otherwise trapped. The same report states that savings could reach $1,200 or more by 2020. Additionally, 30% to 50% of savings companies gain through lower energy bills are passed onto consumers. However, the environmental costs of hydraulic fracturing were not discussed.
