There are several ways power is generated, including fossil fuels, nuclear power, hydropower, wind power, solar power, and geothermal power. Fossil fuels, such as coal, oil, and natural gas, are power plants’ most commonly used energy sources.

Power plants use a process called “nuclear fission”– the splitting of an atom– to create energy. Some nuclear power plants use uranium atoms which are split when they are hit by a neutron, releasing heat and radiation, creating more neutrons. As a motor, it consumes electricity (flows in) to make mechanical power, and as a generator, it consumes mechanical power to produce electricity (flows out). There are many challenges in designing a reliable TEG system that operates at high temperatures. Achieving high efficiency in the system requires extensive engineering design to balance between the heat flow through the modules and maximizing the temperature gradient across them. To do this, designing heat exchanger technologies in the system is one of the most important aspects of TEG engineering.

Part of the turbine’s drivetrain, the main bearing supports the rotating low-speed shaft and reduces friction between moving parts so that the forces from the rotor don’t damage the shaft. (3)  Attached to the turbine shaft is a coil of copper wire that rotates at the same speed as the turbine shaft and is often referred to as an armature. Land-based wind turbines range in size from 100 kilowatts to as large as several megawatts. Our society has become accustomed to using equipment and appliances that run on AC power provided by our local power provider. In most cases this is ideal, but in some cases, AC power is not available. AC power may be unavailable because the distribution grid of the power provider is not operating, or because no distribution grid exists in the area, as would be the case on camping or hiking excursions. AC power can be made available in areas that cannot get AC power from a distribution grid by using a gasoline powered generator to make AC power.


Heat exchangers are used on both sides of the modules to supply this heating and cooling. Direct-drive turbines simplify nacelle systems and can increase efficiency and reliability by avoiding gearbox issues. They work by connecting the rotor directly to the generator to generate electricity. This “pulling” action sets the rotor about 40 to 75 degrees ahead of the armature current. This phase advance is much like that occuring when one bar magnet turns another on the other side of the glass. It is in this way that energy transfers from the shaft and its magnetic field to the armature and into the transmission system.

The utility announced a plan that would harden 650 miles of power lines and upgrade posts to withstand 150 mph winds. Showing kids how to make their own small generator is a great way to teach kids about practical electricity.

Just as there are
AC induction motors, which use electromagnets to produce a rotating magnetic field instead of permanent magnets, so there are alternators that work by induction in a similar way. At the plant level, water flows through a pipe—also known as a penstock—and then spins the blades in a turbine, which, in turn, spins a generator that ultimately produces electricity. Most conventional hydroelectric facilities operate this way, including run-of-the-river systems and pumped storage systems.

Therefore, electricity isn’t an energy source in itself but rather a secondary source of energy. When measuring electricity, the last unit you should know is the coulomb, which is the amount of charge flowing whenever the current is one ampere. The discussion of how to measure electricity will remain incomplete if you don’t mention watts (W), which is a measurement of power. Named after the Scottish inventor, James Watt, this unit of measurement indicates the rate at which work is done. In this article, we’ll give you a clear understanding of what electricity is along with some interesting facts, including how many watts your daily appliances need.

The way electricity is generated is changing as we head towards a greener future. Find out more about wind energy by visiting the Wind Energy Technologies Office web page or browsing the office’s funded activities. Most commonly, they have three blades and operate “upwind,” with the turbine pivoting at the top of the tower so the blades face into the wind. The electrons in the shell closest to the nucleus have a strong attraction to the protons.

Solar energy uses the sun’s light and heat to generate renewable or ‘green’ energy. The most common forms of solar energy are harnessed by solar panels or photovoltaic cells. When rays hit the solar panels, it loosens electrons from their atoms and allows electrons to flow through the cell and generate electricity. In other ways, the sun’s energy is used to boil water and operate a steam turbine to generate electricity in a similar fashion to coal or nuclear power plants.
