What is Alternative Energy?

Alternative energy is energy that is produced that is not harmful to the environment and does not lead to the depletion of the earth's natural resources. Such energy is derived from non-traditional, renewable sources (e.g. solar, wind) as opposed to fossil fuels that are not renewable . Renewable sources can be readily replaced or replenished, either by the earth's natural processes or by human action.

Energy for human activity is obtained from a variety of sources:

  • Fossil Fuels (i.e. oil, gas, and coal).
  • Nuclear Fuels (i.e. uranium, plutonium).
  • Renewable Fuels - geothermal, solar, water (tides, waves), wind power, and bio-fuels (such as firewood and fuel distilled from crops).
Learn more about energy and its uses in this fascinating and informative course.  A great course for anyone interested in gaining an understanding of alternative energy sources.

Aims

  • Describe the nature and scope of alternative energy.
  • Describe the nature and application of electricity.
  • Compare different methods of generating electricity
  • Compare different techniques for storage and use of electricity.
  • Describe the application and operation of different non-electric energy systems.
  • Identify ways to better manage energy consumption.
  • Describe energy conservation techniques.
  • Discuss how to convert a building’s energy supply to an alternative system.

What You Will Do

  • List different insulating materials which may be commonly found inside electrical equipment.
  • Determine a practical example to show the relevance of each of Kirchoff's Laws to a technician, in their daily work.
  • Contact a number of suppliers of alternative energy generating systems (e.g. wind, solar).
  • Find out all that you can about the types of systems they supply. Collect any relevant leaflets and brochures. If possible observe such systems in action.
  • Design a floor plan and describe the current electricity use of a home which you are familiar with (but which uses only mains power supply). This might be the home of a friend, relative, or even your own home.
  • Recommend ways in which this home might reduce reliability on mains supply (either in part or full) by introducing its own electricity generation system.
  • Compare the relative significance of alternative sources of energy including wind, solar, fossil fuels, hydro, etc.
  • Explain electricity, including its nature, terminology and options for applying it as an energy source.

Fruit, Vegetables and HerbsHome grown produce somehow has a special quality. Some say it tastes better, others believe it is just healthier. And there is no doubt it is cheaper! Watching plants grow from seed to harvest and knowing that the armful of vegies and herbs you have just gathered for the evening meal will be on the table within an hour or two of harvest, can be an exciting and satisfying experience.
Bees, Beekeeping and HoneyA very comprehensive eBook about all about bees, bee health, keeping bees, and producing honey.
Fish for Freshwater Aquaculture and AquaponicsChoosing the most suitable fish for any fish farm or aquaponics system is a very important decision. There are a great many aspects to consider and this eBook provides a great overview of the considerations to making such decisions. Suitable for both amateurs and professionals and for large or small scale operations this is an essential resource.
