A brief history of the growth of human civilisation and its realtionship to energy usage.As an aside Oz do you have an opinion on population / resources usage grow and the solution or do you think its all good?
1) The ancient Egyptians harnessed the power of collective effort to build their monuments.
2) The Romans hernessed the fundamental forces of nature (such as gravity) to build their civilisation.
3) The burning of fossil fuel through the industrial revolution has brought about the modern world.
In each case, the advancement came about as a consequence of more efficient and hence cheaper energy sources.
An energy tax such as a carbon tax does the opposite. It makes the cheapest form of energy more expensive and that only increases the potential of conflict (in a global context) and reduces our potential to develop newer, ultimately cheaper energy sources.
The way forward is to develop new sourcces of energy that again reduces the cost of that energy. Only then can our civilisation take the next logical step, the colonisation of space. That may sound far removed from a Julia Gillard's carbon tax, but it's our destiny. Either that or extinction.
