Part of the Hardware glossary: Refurbish, in everyday language, is to renew or to restore to a new condition and/or appearance. In the computer world, refurbished equipment is not necessarily defective in any way; it may just be old (a relative term in the world of computers).When hardware is refurbished, the components are examined and non-working parts are replaced.n the computer world, refurbished equipment is not necessarily defective in any way; it may just be old (a relative term in the world of computers).

This is in contrast to non-renewable fuels such as natural gas, LPG (propane), petroleum and other fossil fuels and nuclear energy.Renewable fuels can include fuels that are synthesized from renewable energy sources, such as wind and solar.hen this process draws its power from renewable energy sources like wind turbines or photovoltaic cells, the production requires little consumption of non-renewable resources. Hydrogen fuel, when produced by renewable sources of energy like wind or solar power, is a renewable fuel.
Biomass energy is any kind of energy that uses a biological organism (plant or animal) as its source. Because the definition of biomass is so broad, fuels that can be considered biomass include a wide variety of items, and researchers are discovering new biomass energy sources all the time.iomass fuel can be converted directly into heat energy through combustion, like the burning of a log in a fireplace. In other cases, biomass is converted into another fuel source; examples include ethanol gasoline made from corn, or methane gas derived from animal waste.
