To understand the issue more fully you need to understand 'Peak Oil', the point when oil production reaches its maximum and after which it goes into irreversible decline. Although this is roughly halfway through all reserves, after this point oil becomes increasingly expensive and difficult to extract. Since demand for oil will outstrip supply the price will drastically increase after the peak and have huge effects on oil dependent industries: transport, agriculture, manufacturing, the military, medicine and many more.
Many people think the Peak is imminent (within 10 years) or has already happened. Coal reserves can be expected to peak later, in the next 20 - 50 years, but as the world's population keeps growing and consumption of fossil fuels increases (despite the known effects to the climate), it is difficult to predict. Of crucial importance is the fact that the development of alternative, renewable energy sources (wind, solar, nuclear fusion) are reliant on oil use.
A:Oil in about 50 years. Natural gas in about 70 yrs and coal in about 250 yrs.
A:At current consumption and the population growth, scientists have determined that the oil supplies will run out in 500 years. A:Our coal will run out in about 40-50 years at the rate we are going at, according to scientists. If we use less coal and more renewable sources, it is sure it will last much longer, but the high demand for coal in industry is always rising as our world modernizes. A:it takes 500-1000 years A:pessimistically 30-40 years, optimistically ~100A:
Get real people. We have only been using oil for a little over a hundred years in any real capacity. If we have already reached peak production, and usage is increasing every day, than we are in trouble. Cant be too many years left!

Natural Gas prices vary depending on the associated market & season. Prices can vary from $5.00 - $9.00/MMBtu depending on the before mentioned variables (and has gone for as high as $25.00 during periods of greatly constrained supply.)
See related link. In comparison to oil and coal, natural gas a fuel source is much more expensive to transport long distances. Discovered gas fields may not be commercial due to the lack of local demand. It is a fossil fuel (non-renewable) that is in limited supply. The burning of natural gas emits greenhouse gases which contribute to global warming.It can leak, potentially causing an explosion.

Renewable energy is natural energy which does not have a limited supply. Renewable energy can be used again and again, and will never run out ...
Fossil fuel, the wind, the Sun, hydro and biomass
natural gas
The US has the world's largest supply of coal.
Yes, mostly by fossil fueled power stations running on coal, oil, natural gas and nuclear.
How is the United States' consumption of fossil fuels affecting the supply and demand of these products?
war doesn't effect fossil fuels , but it does effect fossil fuel prices when a country that has large amount of fossil fuel reserves is politically unstable it will reduce the amount of fossil fuels that can be delivered from it , there by increasing the price since the law of supply states that the lower the supply the higher the price
Fossil fuels (coal, oil, natural gas) are generally available worldwide, but the production is dominated by a few countries with large reserves and the capacity to produce and refine them. Oil and natural gas are more widely sought than coal, which is more difficult to refine and creates greater emissions when burned.
