Fw: [roeoz] Living without electricity -- excellent analysis on service loss

[Denis Frith]

This analysis provides insight into the problems that arise when there is a short term interrruption to electricity supply in a limited developed (in Lancaster in England) area due to a storm. Tasmania had a lesser problem due to very unusual (worst for over one hundred years) flooding coupled to the break down of Bass Link (providing electricity from Victoria). The RAE report, however, only deals with the consequences of a limited spatial and temporal loss. It does not take into account the fundamental fact that the continuing supply of electricity is an unsustainable process. Electricity is a product of industrialization as it is dependent on the installation of technical systems that are made of irreplaceable materials and which inrrevocably age and produce deleterious waste material. Electricity is a form of energy that provides the services described in the report as it irreversibly flows from source to sink as radiation back into space. There is a tendency to go away from using coal-fired power stations to provide base load electricity in order to reduce the rate of greenhouse gas emissions that are increasing the degree of climate disruption and ocean acidifcation and warming. Coal has concentrated energy capital that is rapidly being divested. Sonar and wind systems, often misleadingly called 'renewable' energy systems, use the weak energy income from the Sun to provide some intermittent electricity so can not possibly meet all the electricty demand of the installed infrastructure. Nuclear power stations have recognised limitations so it is uncertain as to how much of the electricty demand that it can meet. Ironically, Australia has a policy rejecting the installation of nuclear power stations even though it is a major supplier of uranium  fro its mines.

So, the report provides insight into the social problems of coping with loss of electricity without providing a sound view of the risk.

The Royal Academy of Engineering in the UK have published this excellent
analysis on the loss of services to Lancaster during a major storm.

Tasmania's problem was not a break in the cable, Hydro Tasmania fried the cable in selling hydro power to the mainland when the price is highest, subsequently also pumping their dam 'dry'
