The rest of the natural gas market is split between residential customers (10%) and commercial users (9%), with a small fraction (1/6 of 1%) going for vehicle fuel. On an inflation-adjusted basis, the prices paid by industrial users for natural gas in May were the lowest since at least January 2000, when the Department of Energy's monthly data series starts (see red line in chart). And unlike renewable energies like solar and wind, the natural gas boom is happening without any taxpayer-funded grants, subsidies, credits and loans.
