Some generators are powered by non-renewable fossil fuels, that is, by burning coal, oil or gas.
Other generators are powered by renewable fuels, for example, the power of falling water, or geothermal steam, or the burning of biofuels like biogas, biodiesel, biomass and wood.
Yes, there are bio-fuel compatible portable generators. For example, Kentec Generators create these, which are very Earth-friendly. Powered Generators also supply bio-fuel compatible portable generators.
Electricity itself is not a fossil fuel but, can be generated by steam turbines and generators where the steam has been generated by heating water in fossil fuel boilers.
Yes, wind powered generators are worth the price that they can produce. Because they have no fuel or pollution s that is made by utilizing the wind energy.
That depends on the generator. The majority of large scale electric generators at power plants are powered by fossil fuels or by nuclear materials, which heat water to produce steam, and the high pressure steam is used to spin a turbine, which powers the generator. Home generators are usually powered by the internal combustion of a fossil fuel, such as gasoline or propane. Hydroelectric generators are powered by the energy of large amounts of water falling over the side of a dam. There are also generators powered by wind, but although photovoltaic (solar, electricity producing) panels produce electricity, I am not sure they are referred to as "generators" per say, because of their mechanism of action.
Fossil fuels, electric, and fuel cells are three major ways an automobile can be powered.
The term defines itself- an appliance using fossil fuels- such as coal and oil. ( as wood is in a sense regenerative- it is not strictly speaking a fossil fuel) a classic- and appropriately obsolete example would be a coal burning ( Pot Belly) stove. These, of course have antique value.
You can get affordable gas powered generators at electricgeneratorsdirect.com they have a wide selection of gas powered generators at affordable prices
By 2217 all the fossil fuels will have been used up so there will be no fossil fuel powered cars around then.

Coal is a fossil fuel, it is used to generate electricity or steam to power machines. Aluminium mining is the extraction of the ore of Aluminium, "bauxite". To mine bauxite you would need to use oil (another fossil fuel) powered machines and dynamite. So the answer is NO, coal powered energy is not an alternative for Aluminium mining.
