Types of Generators
Amount of energy made
448 wind turbines can generate power for around 317,000 households
About 707.6 houses per turbine.
More for other generators
Over 88% of all electricity in the US come from Steam generators
In a steam engine, water is pressured and super-heated into steam. The steam then taking on the form of a supercritical fluid. This gas liquid then spins turbines to produce electricity

What is generator?
A generator is a machine that produces electricity. This is completed by creating a force to spin the turbine in side of the generator. By spinning the turbine a magnetic field is created, and the result is electricity
Nuclear generators use the same process used in creating the atomic bombs. Nuclear fission(the process of splitting atoms for extreme energy) is used to heat water. The steam from the water then spins the turbine.
Very efficient, waste can be harmful.
Wind power is the fundamental, since generators work by rotating a shaft to create electricity. The turbines turn this with the wind catching it.
A solar panel has photovoltaic cells that genorate energy. They work by having light waves knock off the electrons from its "screen". (These are silcon covrs on the panels)
Generator works using combustion
Combustion is where the engine injects a mixture of fuel and air into a combustion chamber, where a piston compresses the mix
A spark plug then ignites the fuel, driving the piston down and turning a crankshaft
The crankshaft, in turn, spins the generator's rotor in an electromagnetic field, generating an electric current that can charge batteries, power appliances or even run high-wattage tools, depending on the generator's size
Kinetic generators use the movement of an object to create the electromagnetic field that produces electricity.
Riding stationary bicycles, using body movements, or other everyday motions are just some of the ways kinetic energy can be harnessed.
Unbelievably the entire generator is encased in a battery.
Coal generators are one of the first generators ever invented. Before solar, nuclear, or wind there was coal. It works by burning coal, which generates heat. This then boils water to turn a turbine.
The ethanol and diesel engine are very much alike. The only big difference is the diesel uses diesel and ethanol uses ethanol. Ethanol is a renewable alcohol fuel.
Oil generators can be good and bad. They can be good by the amount of energy one of them produce. The hard part is what type of oil one of these generators needs. Most people use 10W30 and suggest to use reglar oil when it is cold.
You have a dam to hold water. Then you have pipes to transfer water, then there is a scroll case at the end. In the scroll case there are wicket gates that control how much water goes into the turbine. The turbine and pipe connecting the turbine to the generator is called the runner. At the top is the exciter which moves the power through the AVR. The generator is under the exciter.
On most generators heat from the burning resources is used to heat water to produce steam, which turns the turbines.
On others, like wind and solar. Inexhaustible
Diesel powered generators are used more than any other fuel because it burns not explodes
"Coal Fired Generation." Matt Mcdonald. Matt Mcdonald, n.d. Web. <https%3A%2F%2Fwww.mottmac.com%2Fpower%2Fcoal-fired-generation>.
Diesel powered generators work with four simple steps these are
Intake: Air (light blue) is drawn into the cylinder through the open green air inlet valve on the right as the piston moves down.
Compression: The inlet valve closes, the piston moves up, and compresses the air mixture, heating it up. Fuel (dark blue) is injected into the hot gas through the central fuel injection valve and spontaneously ignites. Unlike with a gas engine, no sparking plug is needed to make this happen.
Power: As the air fuel mixture ignites and burns, it pushes the piston down, driving the crankshaft (red wheel at bottom) that sends power to the wheels.
Exhaust: The green outlet valve on the left opens to let out the exhaust gases, pushed out by the returning piston.
Bio Generators work basically by burning natural materiel like peat and nut shells
The gas from the burned things then moves the turbines which powers the generator
