The twentieth century way of life has been made available, largely due to the miracle of cheap energy. The price of energy has been at record lows for the past century and a half.As oil becomes increasingly scarce, it is becoming obvious to everyone, that the rapid economic and industrial growth we have enjoyed for that time is not sustainable.Now, the hunt is on. For renewable sources of energy, for alternative sources of energy, for a way of life that is less dependent on cheap energy.

Australian scientists have mapped out the best places across the nation’s southern coast for generating wave energy, all the way from Geraldton in Western Australia to King Island in Tasmania.

A new CSIRO energy atlas shows that if just 10 per cent of the energy generated from waves was harnessed it would meet half of the nation’s current electricity consumption.

Australia’s southern coastline has been identified by the World Energy Council as one of the world’s best sites for generating wave energy.

The Centre for Australian Weather and Climate Research’s Dr Mark Hemer says even the small fraction of energy harnessed from Australia’s coast will be enough to meet future government targets.

“If we look at the sustained energy resource along the southern coastline – and we’re looking between Geraldton in West Australia and southern tip of Tasmania – that has a sustained wave energy resource of about… five times larger than Australia’s present day electricity consumption,” he said.

The Problem:
Electricity for railways

The Social Invention:
Solar powered cars have been talked about for some time. Indeed I believe there is an annual race to find the fastest. Cars are actually to small to collect enough power from the sun, and solar powerd cars are specially designed lightweigh one-man vehicles. Not really practical vehicles.

However, it is actually a much more practical proposition to build a solar powered railway in many parts of the world.

Railways require a swathe of land probably on average about 20 metres across. Thus every kilometre of track could provide 20,000 square metres of solar collector.

How to be fully renewable in 10 years

BEN CUBBY Largest wind farm in southern hemisphere for Victoria

AUSTRALIA could switch completely to renewable energy within a decade by building a dozen vast, new solar power stations and about 6500 wind turbines, according to a major new study.

The Zero Carbon Australia Stationary Energy Plan – a collaboration between Melbourne University’s Energy Research Institute, the environment group Beyond Zero Emissions and engineers Sinclair Knight Merz, puts the cost at $37 billion in private funding and public investment every year for the next decade.
