Alternative power generators produce electricity from renewable energy sources, such as wind, flowing water, solar energy and biomass, which create less environmental damage and pollution than fossil fuels

Electrical power generators transform mechanical energy into electrical energy, typically for backup or emergency power. Generators can produce either AC or DC power and are typically powered by a fuel engine

PV and solar power systems convert light into electricity. They are the building blocks of photovoltaic (PV) modules

Wind turbines convert the kinetic energy from wind into mechanical energy. When used with an electrical generator, the rotation of the wind turbine’s blades turns a shaft to produce electricity

Flywheel power systems are high-speed, bore-loaded, carbon fiber flywheel rotors with integrated iron-less motor / generators contained inside a sealed, vacuum housing

Hydro turbines are used to transmit mechanical power and produce electricity. Hydro turbines convert water pressure into mechanical shaft power that can be used to drive an electricity generator, grind a mill, or move some other device

Fuel cells produce electricity and heat electrochemically by combining oxygen from the air with a fuel, preferably hydrogen, from methanol, natural gas, or petroleum. Reformers are often used in conjunction with fuel cells.

Manual pulse generators institute a command pulse when the handle is turned manually

Industrial gas generation equipment is used to generate or dissociate gases for industrial processes.

Voltage regulators are devices that enable generators to provide voltage control capabilities

Energy product testing services test, evaluate, and analyze the safety, efficiency and performance of energy storage, power generation, and transmission systems that use conventional, renewable or alternative energy

Energy use consulting services help businesses design energy-efficient buildings, evaluate current energy usage, and develop energy management plans.

Steam injection heaters inject steam into a system to maintain or raise temperature levels.

Power supplies are devices that produce AC or DC power.  This grouping includes current sources, DC power supplies, AC-DC adapters, DC-DC converters, AC power sources, and DC-AC inverters

Signal generators and waveform generators are used to test and align all types of transmitters and receivers, to measure frequency and to generate a signal, waveform or noise source. Signal generators can use AC energy, audio frequency (AF) and radio frequency (RF) to function
