Fossil Fuels are all organic based substances that can be used to generate energy, be it heat or mechanical work. The parent material of fossil fuels ranges considerably but all of it was once living creatures whose remains were buried and trapped within the earth before being properly decomposed. When fossil fuels will be depleted is a question of much debate. The reserves of specific fossil fuels vary, for example coal is more plentiful than oil or natural gas. It is likely that fossil fuels will never actually be depleted because long before that happens other sources of energy (such as solar/wind/geothermal) will become much more economically viable. Unlike fossil fuels these sources of energy are sustainable and will never be depleted. Also the potential for energy production (especially solar) is much greater than any fossil fuel. This transition is inevitable, but it is impossible to say when it will happen. Over the past few years we have seen a general increase in the cost of energy (particularly oil). This is because the global demand for these resources has increased faster than the global production. Over the last few years World oil production has leveled off, but demand has continued to rise so expect the price at the pump to rise steadily with each year. Though coal reserves are much more vast it is likely that in a few decades world production of that resource will level off as well. In my opinion this will be the breaking point where green energies actually become more affordable than fossil fuels. Short answer to your question NEVER, but you'll probably stop using them in 30-40 years.
A fossil fuel is a fuel that cannot be replaced within a generation. They can however be replaced over millions of years.
Gone forever. Fossil fuels are those that were created millions of years ago, and when they are gone, there is no more of them.
no but they take millions of years to form
We need to conserve fossil fuels because they are non-renewable. Once our reserves are depleted, we will have to come up with synthetic fuels. We do have synthetic oil, but not in the quantities that the world needs.
Unknown, because they are constantly finding new fossil fuels and new ways to get at the fuels. Additionally, new technologies have been developed that can extract more fuel from previously depleted fossil fuel fields. An example is the 2 newly discovered oil fields in the continental United States that are huge.
Disposal of depleted nuclear fuels its self a pollution problem.

Fossil fuels are getting depleted because they are formed from the remains of ancient plants and animals that lived millions of years ago. The extraction and consumption of these fuels at a rapid rate far exceeds the time it takes for new deposits to form. Additionally, the burning of fossil fuels releases carbon dioxide into the atmosphere, contributing to climate change, which has pushed for a shift towards renewable energy sources.
fossil fuels
Earths sources of concentrated usable are being depleted. These are mainly fossil fuels that are running out. However there is still wind, water and solar energy.
nonrenewable energy sources are sources that are depleted sources as fossil fuels (wood, coal, natural gas, and oil)
how r fossil fuels canverted to fuels
Non-fossil fuels, renewable fuels.
