As the world is waking up, the transition to renewable energy is making headway. Here's a brief report highlighting the reserves and usage rates for the world's fossil fuels including coal, oil and natural gas. Fossil fuels are bio-materials comprising hydrocarbon, which can be used as an energy source. They can be extracted by drilling the Earth's crust.
Through lithification and degradation over millions of years, the organic matter turns into coal, natural gas, and oil. For example, the oil reserves in the North Sea are about million years old and coal in the UK started formed around million years ago.
Fossil fuels differ in energy density and pollution capacity. The longevity of a substance depends on the usage rate and reserves. The reserves category includes transformation and loss. The total resource figure includes proved reserves, probable reserves, and possible reserves. The usage rate modifies depending on the efficiency of the consumption equipment. The numbers depend on technological advancements. Coal is the first fossil fuel source ever used. It's easy to get and use.
Consider the energy you can get from charcoal to understand coal's energy density. But coal aerosolises and creates water contaminants and breathing hazards when it's extracted. China, Russia, the United States, and India hold around 1. Figures show a low 0. And production is down by 0. This means that coal deposits may be depleted within years. Underground oil reserves require drilling, pumping, and processing. Oil reserves are closely monitored and figures reflect about 1. Global consumption currently stands at 11 billion tonnes of oil annually.
Reserves are disappearing at a rate of 4 billion tons every year. At the present rate, oil deposits could run out within 50 years. Compared to coal and oil, natural gas is the most renewable. Huge reserves come from ancient dead microorganisms, but not all sources are millions of years old.
For example, landfills and livestock produce methane, which is a natural gas. As of , about 6, trillion cubic feet of natural gas are available. The United States, Algeria, and Nigeria hold the largest reserves.
Most deposits require complex drilling and hydraulic fracturing to reach. Natural gas reserves are expected to last about years. Fossil fuels are available in limited supply.
At the current consumption rate, fossil fuels aren't sustainable energy sources. Most attempts have, however, been proven wrong.
Meanwhile, actual global oil production and consumption continues to rise. 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.
