How long can petroleum last

Since a large portion of oil is consumed by vehicles, technological developments such as electric cars or hybrids play a role in demand as well. The signs of decreasing demand have begun to appear in the past few years, Williams-Derry says. And the COVID pandemic has only accelerated this drop in demand as the past year has seen a significant decrease in the numbers of cars on the road.

Monitor journalism changes lives because we open that too-small box that most people think they live in. We believe news can and should expand a sense of identity and possibility beyond narrow conventional expectations.

My work in Kenya, for example, was heavily influenced by a Christian Science Monitor article I had forced myself to read 10 years earlier.

The difficulty in attempting to construct these curves is that our discovery of reserves and technological potential to extract these reserves economically evolves with time. If we look at trends in proven fuel reserves, we see that our reported oil reserves have not decreased but increased by more than 50 percent, and natural gas by more than 55 percent, since Again, these figures are only useful as a static measure; they will continue to vary with time as our capacity to economically source and extract fossil fuels changes, and our levels of consumption rise or fall.

However, whilst depleting reserves could become a pressing issue years from now, there is another important limit to fossil fuel production: climate change. Carbon dioxide emissions remain trapped in the atmosphere for long periods of time, building up an atmospheric stock that leads temperatures to rise.
