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 fuels are organic materials produced in a renewable manner. Two categories of biomass fuels, woody fuels and animal wastes, comprise the vast majority of available biomass fuels.Municipal solid waste (MSW) is also a source of biomass fuel. Biomass fuels have low energy densities compared to fossil fuels.ifferent types of woody fuels can typically be mixed together as a common fuel, although differing moisture content and chemical makeup can affect the overall conversion rate or efficiency of a biomass project. There are at least six subgroups of woody fuels.
