gas turbine are used for expansion of high pressure gas,which rotates the rotor coupled with generator and hence electricity is finally produced.Gas turbine operate on brayton cycle.
No, there are gas turbines powered by hot gas formed by the burning of kerosene (in aircraft engines) or by natural gas combustion for electrical generation. Gas turbines are also used in some naval ships. Then there are water turbines as used in hydro power. Also, wind can drive turbines.
You obviously don't understand what fossil fuels are-coal, oil, natural gas. Wind turbines don't need any of these to produce electricity

Wind turbines.
William W. Bathie has written: 'Fundamentals of gas turbines' -- subject(s): Gas-turbines
In the oil and Gas industries , power is generated by electrical generators driven by Gas turbines , Steam turbines , reciprocating engines or in some cases turbo expanders.

three types of combustion chamber are used in gas turbine engine 1) Can type. 1.1 single can ; this again can be of two type a) straight through design b)reverse flow design 1.2 multiple can 2) tubo-annular (can-annular) 3) annular
Gas turbines are typically much smaller and therefore cheaper. Also, steam turbines require a long time for the fuel (coal, oil, uranium) to heat up the water and so changes in power output are slow. Gas turbines rely partly on the burning and instant expansion of gases, meaning that turbines start and stop much faster.
