World energy resources are the estimated maximum capacity for energy production given all available resources on Earth. They can be divided by type into fossil fuelnuclear fuel and renewable resources. Remaining reserves of fossil fuel are estimated as: These are the proven energy reserves; real reserves may be up to a factor 4 larger. Significant uncertainty exists for these numbers. Estimating the remaining fossil fuels on the planet depends on a detailed understanding of the Earth's crust.
In addition to uncertainty in real reserves, there is significant uncertainty in technological and economical factors that impact what percentage of reserves can be recovered gainfully. In general the easiest to reach deposits are the first extracted. Factors affecting the cost of exploiting the remaining reserves include the accessibility of fossil deposits, the level of sulfur and other pollutants in the oil and the coal, transportation costs, and societal instability in producing regions.
Coal is the most abundant and burned fossil fuel. This was the fuel that launched the industrial revolution and has continued to grow in use; China, which already has many of the world's most polluted cities, [4] was in building about two coal-fired power plants every week.
With the Fischer- Tropsch process it is possible to make liquid fuels such as diesel and jet fuel from coal.

Improvements in technology and wide exploration led to a major increase in recoverable natural gas reserves as shale fracking methods were developed. At present usage rates, natural gas could supply most of the world's energy needs for between and years, depending on increase in consumption over time. Current consensus among the 18 recognized estimates of supply profiles is that the peak of extraction will occur in at the rate of million barrels per day mbd.
Current oil consumption is at the rate of 0. There is growing concern that peak oil production may be reached in the near future, resulting in severe oil price increases. The ASPO predicts peak year to be in Some other theories present the view that it has already taken place in World crude oil production including lease condensates according to US EIA data decreased from a peak of Political considerations over the security of supplies, environmental concerns related to global warming and sustainability are expected to move the world's energy consumption away from fossil fuels.
The concept of peak oil shows that about half of the available petroleum resources have been produced, and predicts a decrease of production. A government move away from fossil fuels would most likely create economic pressure through carbon emissions and green taxation. Some countries are taking action as a result of the Kyoto Protocoland further steps in this direction are proposed. The antithesis of sustainability is a disregard for limits, commonly referred to as the Easter Island Effect, which is the concept of being unable to develop sustainability, resulting in the depletion of natural resources.
IPCC estimated currently proved economically recoverable uranium deposits for once-through fuel cycles reactors to be only 2 ZJ. The ultimately recoverable uranium is estimated to be 17 ZJ for once-through reactors and ZJ with reprocessing and fast breeder reactors.

Resources and technology do not constrain the capacity of nuclear power to contribute to meeting the energy demand for the 21st century. However, political and environmental concerns about nuclear safety and radioactive waste started to limit the growth of this energy supply at the end of last century, particularly due to a number of nuclear accidents.
Concerns about nuclear proliferation especially with plutonium produced by breeder reactors mean that the development of nuclear power by countries such as Iran and Syria is being actively discouraged by the international community.
Although at the beginning of the 21st century uranium is the primary nuclear fuel worldwide, others such as thorium and hydrogen had been under investigation since the middle of the 20th century. Thorium reserves significantly exceed those of uranium, and of course hydrogen is abundant. It is also considered by many to be easier to obtain than uranium. While uranium mines are enclosed underground and thus very dangerous for the miners, thorium is taken from open pits, and is estimated to be roughly three times as abundant as uranium in the Earth's crust.
Since the s, numerous facilities throughout the world have burned Thorium. Alternatives for energy production through fusion of hydrogen has been under investigation since the s.
No materials can withstand the temperatures required to ignite the fuel, so it must be confined by methods which use no materials. Magnetic and inertial confinement are the main alternatives CadaracheInertial confinement fusion both of which are hot research topics in the early years of the 21st century.
Fusion power is the process driving the sun and other stars. It generates large quantities of heat by fusing the nuclei of hydrogen or helium isotopes, which may be derived from seawater. The heat can theoretically be harnessed to generate electricity.
The temperatures and pressures needed to sustain fusion make it a very difficult process to control.
Fusion is theoretically able to supply vast quantities of energy, with relatively little pollution. Renewable resources making money freelance web developer available each year, unlike non-renewable resources, which are eventually depleted.
A simple comparison is a coal mine and a forest. While the forest could be depleted, if it is managed it represents a continuous supply of energy, vs. Most of earth's available energy resources are renewable resources. Renewable resources account for more than 93 percent of total U. Annual renewable resources were multiplied times thirty years for comparison with non-renewable resources.
In other words, if all non-renewable resources were uniformly exhausted in 30 years, they would only account for 7 percent of available resources each year, if all available renewable resources were developed. Renewable energy sources are even larger than the traditional fossil fuels and in theory can easily supply the world's insider trading and the stock market henry manne needs.
While it is not possible to capture all, or even most, of this energy, capturing less than 0. Barriers to further solar generation include the high price of making solar cells and reliance on weather patterns to generate electricity.
Also, current solar generation does not produce electricity at night, which is a particular problem in high northern and southern latitude countries; energy demand is highest in winter, while availability of solar energy is lowest.
This could be overcome by buying power from countries closer to the equator during winter months, and may also be addressed with technological developments such as the development of inexpensive energy storage. JapanEuropeChinaU.
Most of this wind energy is available over the open ocean. At the end of0. These tidal fluctuations result in dissipation at an average rate of about 3. Another physical limitation is the energy available in the tidal fluctuations of the oceans, which is about 0.
Without forcing, daily forex tips to trade energy would be dissipated at a dissipation rate of 3. So, dissipation plays a significant role in the tidal dynamics of the oceans. Therefore, this limits the available tidal planetary resources inc share price to around 0.
Waves are derived from wind, which is in turn derived from solar energy, and at each conversion there is a drop of about two orders of magnitude in available energy. The total power of waves that wash against our shores add up to 3 TW. Estimates of exploitable worldwide geothermal energy resources vary considerably, depending on assumed investments in technology and exploration and guesses about geological formations.
Production of biomass and biofuels are growing industries as interest in sustainable fuel sources is growing. Utilizing waste work from home general transcription avoids a food vs fuel trade-off, and apexinvesting market world s binary options methane gas reduces greenhouse gas emissions, because even though it releases carbon dioxide, carbon dioxide is 23 times less of a greenhouse gas than is methane.
Biofuels represent a sustainable partial replacement for fossil fuels, but their net impact on greenhouse gas emissions depends on the agricultural practices used to grow the plants used as feedstock to create the fuels.
While it is widely believed that biofuels can be carbon-neutral, there is evidence that biofuels produced by current farming methods are substantial net carbon emitters.
