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). When hardware is refurbished, the components are examined and non-working parts are replaced.
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.
Non-renewable energy is energy from fossil fuels (coal, crude oil, natural gas) and uranium. Fossil fuels are mainly made up of Carbon. It is believed that fossil fuels were formed over 300 million years ago, when the earth was a lot different in its landscape. It had swampy forests and very shallow seas.ir, water and land pollution are all consequences of using fossil fuels. In the pages that follow, we shall take a look at what each source of non-renewable energy is made of, and how they are used. Note that not all non-renewable energy comes from fossil fuels. There is also uranium, which is not a fossil fuel.
