Large scale electrical energy production largely depends on the use of turbines. Nearly all of the world's power that is supplied to a major grid is produced by turbines. From steam turbines used at coal-burning electricity plants to liquid water turbines used at hydro-electric plants, turbines are versatile and can be used in a number of applications. There are also gas turbines that com bust natural gas or diesel fuel for them to refuse. remote locations or where a large backup power supply is required.
