Fuels and fuel products include gasoline, diesel oil, natural gas, propane, coal, fossil fuels, biofuels and other combustible fluids or materials

Oil sensors and oil analyzers are used in automotive or industrial machinery applications to sense oil levels, and check for contamination, and particulates, viscosity and/or temperature.

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.

Power generation systems are power generators and related systems that are used in power plants or large-scale power generation facilities.

Cogeneration equipment produces power and thermal energy from a common fuel source, generally one that is considered to be a waste product from another process.

Alternative energy installation services specify and install photovoltaic, wind energy, and other distributed energy production systems for commercial and residential applications.
