Summary The synchronous motor: 1. requires to be started by an external prime mover. 2. Runs only at synchronous speed, this is an advantage where continuous speed is required but a disadvantage where a variable speed is required. 3. Can be used to adjust the power factor of a system at the same time it is driving a mechanical load. 41.

Wind Fights Solar; Triangle Wins | Do the Math
If we convert sunlight to electricity at 15% efficiency, and wind at 45% efficiency (typical numbers), we have 30 W vs. 3.5 W. Solar beats wind (in that same location) by an order of magnitude. Comparing optimal solar sites to optimal wind sites (taking 1000 W/m² by rotor area), solar wins by a factor of five.

coal is converted in to electricity in thermal power plant. Coal is pulverized to the consistency of talcum powder. Then powdered coal is blown into the water wall boiler where it is burned at temperature higher than 1300°C. The heat in the combustion gas is transferred into steam. This high-pressure steam is used to run the steam turbine to spin.
