King Hubbert , in , published his hypothesis that for any given region, a fossil fuel production curve would follow a bell-shaped curve, with production first increasing following discovery of new resources and improved extraction methods, peaking, then ultimately declining as resources became depleted.
His prediction that the United States would peak in oil production in actually came true although it peaked 17 percent higher than he projected, and its pathway since has not followed the bell-shaped curve he predicted.
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.
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. As the world's population grows, the problem is escalating. But limited resources aren't the only concern. The use of fossil fuels for energy includes a variety of downsides such as increased carbon emissions, air and ocean pollution, habitat destruction and huge transportation costs.
Enterprises and governments have enjoyed short-term gains from fossil fuel investments, but they're shifting focus towards renewable energy resources. Green energy sourced from solar and wind power is sustainable. It's produced by resources, which won't disappear. It also prevents climate change by offsetting and lowering carbon emissions.
For example, solar power technology has a 2-year energy payback period. This means that a solar park will produce the amount of energy, which was used in its production within only 2 years. After this period, the park can produce decades-worth of clean energy. To protect the environment and fight climate change, the world must shift towards renewable energy solutions. When will fossil fuels run out? If the world understands the planet's changing energy requirements and implements advanced tech solutions, hopefully, fossil fuels will never run out.
Limiting the usage of fossil fuels is the only hope to ensure that the planet doesn't risk complete depletion and the dangerous consequences.

Here are 7 ways in which Australia could solve its plastic problem.
Read July 24th, Shining the spotlight on solar-powered communities in Africa topic: Renewables by: Bob Koigi The proliferation of solar panels is granting millions across Africa access to electricity. But financing hurdles may slow down this sustainable enterprise. I have read, understood and confirm FairPlanet's Privacy Policy.
How does this work? This particular watery end can be avoided if energy use is directed away from fossil fuels and towards renewable energy options like wind and solar or even nuclear energy, though getting rid of nuclear waste presents a different set of long-term problems.
The authors predict that sea levels will creep up as ice in the polar regions melts, at a rate of a little over an inch per year.
