Power is generated at a centralized location and transmitted via Grid to the industry. Owing to the intrinsic limited efficiency of Rankine Cycle, only about 30% of Energy generated by burning the Coal is converted into Electrical Power. Up to 20% of this power is lost as Transmission and Distribution losses, thus only about 24% of Energy reaches the consumption point. The remaining 76% is dumped as Heat to the atmosphere adding to Global Warming. Every kWh of Power generated adds about 1 kg of CO2 to the atmosphere.
As an easy example, only a small 1250 kW capacity out of the large Centralized Thermal Power Plant is diagrammatically represented here. Out of 1250 kW about 20% is lost as Transmission and Distribution losses and only 1000 kW reaches the consumption point. A 1250 kW Centralized Power generation adds 10,000 Tons of CO2 to the atmosphere annually.
