fossil fuels can be used as an energy source to power all vehicles and most machinery
Fossil fuels are energy sources that come from the reamins of plants and animals. These remains are millions of years old.
They have been the most efficient energy source available
Any energy source that is an alternative to fossil fuels. They are used to avoid the damages that fossil fuels do to our environment such as: Carbon dioxide emissions which leads to global warming and acid rain.
All fuels by definition are used to produce energy, fossil fuels are no exception. (Shorter answer: Yes.)
Fossil fuels are produced by the slow alteration of masses of vegetation, compressed underground. That vegetation originally used the energy of sunlight to grow, therefore it is the sun's energy which is stored in chemical form, in fossil fuels.
Because it cant be used again once it's first used
That would be fossil fuels.
they can be used instead of fossil fuels like bio diesel which can be used in automobiles.
Scientists use fossil fuels because they are a source of energy that is relatively cheap and readily available. Fossil fuels are used in many scientific processes and experiments that require a consistent and convenient source of power. However, there is a growing concern about the impact of fossil fuels on the environment and efforts are being made to transition to more sustainable energy sources.
Examples of fossil fuels are coal, oil and natural gas. Fossil fuels are nonrenewable energy sources which can be used to make electricity in a power station but it is very bad for the planet and global warming. Fossil fuels are running out slowly so we need to think of something else which is a renewable source of energy.
Geothermal energy can be used to generate electricity by tapping into the Earth's heat through geothermal power plants. These plants use the steam and hot water from underground sources to turn turbines and produce electricity without the need for fossil fuels. It is a renewable and sustainable energy source that can help reduce our dependence on fossil fuels for electricity generation.
An example of non-renewable resources is fossil fuels. Once fossil fuels have been used up and no new sources found, then we can no longer use fossil fuels. A source of energy will no longer be available to us. It took many million of years for nature to produce fossil fuels, something we are unable to repeat.
