The Difference Between Alternative And Renewable Energy Systems

The Difference Between Alternative And Renewable Energy Systems Image
Many people use the terms "Alternative Energy" and Renewable Energy" interchangeably, however, they actually mean two distinct things. Renewable energy systems run on fuels that can be naturally renewed - they are not burned off. Alternative energy systems provide fuel efficiency through an alternative means of using fuel. Put differently, the word "renewable" refers to the fuel itself, while the word "alternative" refers to the equipment being used. Of course a system cannot technically be an alternative energy system if it is not saving energy. Some home energy systems are one or the other, while others are both, as follows:

Geothermal Heat Pumps: These systems are both alternative and renewable, running on the natural heat of the earth and also built entirely differently than conventional systems.

Solar Roofing: These system are often renewable and alternative as well, though some might say they are renewable but not alternative because the internal mechanisms often look very similar to conventional systems.

Condensing Boilers: A good example of an alternative but not renewable energy system. Condensing Boilers save energy and reduce your carbon footprint but do not run on renewable fuels.

Micro CHP: Another example of an alternative but not renewable system

Micro Hydro: Renewable and Alternative energy systems

These are just some examples, and you should note that some would disagree with our definitions. In addition, keep in mind that some alternative energy home systems such as micro chp and condensing boilers can be made to run on renewable fuels, which would be the ideal situation for these types of system.
