Fossil fuels have become the most commonly used source of energy, not because of their efficiencies, but primarily due to the ease in extracting the energy from the source and the seemingly endless supply. Arguably other factors outside the energy source itself have a significant influence on the buoyancy of the industry, but those factors are not the focus of this text. The big question is, are we running out of energy? And the answer is a resounding, no. The current energy crisis from a simplistic view can be divided into four components:

  • security of supply
  • environmental impact
  • energy consumption
  • growth in energy consumption

Off shore Wind Farm (Sweden)

The concept of large scale wind farms is to augment existing supplies. The concept in wind farming is to harvest the wind to its maximum potential, which is utilising all of the wind captured in the farming region and to take up as much of the utility load that is possible, without loss of supply integrity. This differs from most line generators where the aim is to minimise fuel use and spinning reserve. There is a number of practical limitations, primarily, dynamic stability off the grid, which limits the percentage of wind energy which can be applied to the grid at any one time. Modern technology and developments are pushing these boundaries promising new horizons.

Across Australia on veggie oil


The proof is in the pudding, traveling from one side of Australia and back, a distance of over 11,000 km on less than $100.00 of diesel is proof enough regarding the viability of waste veggie oil’s suitability as a replacement fuel for diesel engines. The availability of waste oil was a surprise, with abundant supplies as needed en route. A number of planned oil pick ups were organized before we left in exchange for presentations on Renewable Energy and Sustainability to a school or community group of choice.
