The amount of fuel (natural gas) used to produce electricity.
The 2 most common and obvious are: Electricity from batteries. (Photovoltaic cells use physical rather than chemical changes.) Heat from combustion - for heating buildings, industrial processes etc., and in heat-engines (internal-combustion, steam-turbine, gas-turbine, and jet - in former times, hot-air engines and steam engines).
The most popular method of generating electricty is, to use a steam turbine to drive a generator. The fuel used, is burnt to produce heat. The heat is used to make steam, by boiling water. So gas is burnt to produce heat, which boils water to make steam, which spins a turbine connected to a generator. Gas could also be used in an internal combustion engine, which is connected to a generator. This is normally used for small scale production, not on a national grid.
The gas may be burned in a jet turbine, turning the electrical generator. and/or burned to heat water into steam- which turns a turbine, which turns a generator.
Most people use natural gas to heat homes, but natural gas itself has to be burned. So technically we are using combustion to heat our homes
Yes, and not only heat but it does produce carbon monoxide also as a by product of combustion
The heat rate of a gas turbine using petroleum is 13,622. On the other hand, gas turbines that use natural gas produce a heat rate of 11,499.
what the deffrant bettwen steam and gas
Main difference is that in a gas turbine, combustion is continuous. In a piston engine, combustion is pulsed.
In an open cycle gas turbine, the gases that are produced by combustion go directly into the atmosphere, though the heat produced can sometimes be reclaimed. In a closed cycle gas turbine, the gases produced are reused and are not emitted into the atmosphere.

the induction of gas is forcedthrough a venturi design, causing higher tempuratures. Increasing combustion rate. Causing high efficiency.
Thermal energy is just heat. To convert it to mechanical energy you need some sort of heat engine, like an internal combustion engine or a gas turbine.
Basically, a gas turbine is powered by gas under pressure, The gas is pressurized by burning some type of fuel such as kerosene, jet fuel, or propane. That heat causes air expansion, and the subsequent inflow of air makes the turbine spin. A gas turbine consists of three main parts; a combustion chamber, a turbine and a compressor. Air and fuel are mixed in the combustion chamber where it is ignited and increases in speed and power. This power is directed over the turbine blades which spin the turbine and power the compressor. It's a pretty simple process: heated fuel causes pressure and air expansion. The expanded air causes a turbine to spin. That is how gas turbines like jet engines work.
In an open cycle gas turbine, the gases that are produced by combustion go directly into the atmosphere, though the heat produced can sometimes be reclaimed. In a closed cycle gas turbine, the gases produced are reused and are not emitted into the atmosphere.
Gas turbine works with the use of many kinds of fuel to run a compressor. The compressor will bring the atmospheric air flows through its highest pressure and with the addition of fuel into the air it will ignite and then the combustion will generate a high-temperature flow.
Gas turbine engines takes in air, compresses it, mix it with fuel, then burns it in combustion chamber. then this expanded gas drives the turbine
By throttling the amount of fuel delivered to the combustion chamber
