Gas provides electricity and is also used for cooking, heating and fuelling numerous industrial operations. There is no doubt that oil and gas are the cornerstones of modern society.

However, with the diminishing number of conventional reservoirs and increasing concern of the rising global temperature, scientists started wondering if oil and gas will remain our primary energy resource in 30 years. In this essay, we are going to examine the amount of remaining oil and gas reservoirs, unconventional production methods and their costs, as well as current renewables’ situations and costs.
