AUSTRALIA-WAVE ENERGY GENERATION


Last month, Australia’s southern area was nominated by the “World Energy Council” as one of the world’s most promising sites for wave-energy generation. If you didn’t know wave energy is starting to be considered as a viable, renewable source of energy to create electricity. Interesting.

From Science Daily:
One problem for wave-energy developers, however, is that previous estimates of wave-energy potential are based on information in deep ocean water, while “wave-energy generation systems are typically positioned near to shore,” says physical oceanographer Mark Hemer of Australia’s CSIRO Wealth for Oceans National research flagship.

In a paper in the AIP’s Journal of Renewable and Sustainable Energy, Hemer and colleague David Griffin provide new estimates of the wave-energy potential of Australia’s near-shore regions. They also calculate how much of Australia’s energy needs could be obtained from wave energy alone. Australia’s present-day electricity consumption is 130,000 gigawatt-hours/year. Hemer and Griffin show that if 10 percent of the near-shore wave energy available along Australia’s Southern coastline could be converted into electricity, half of the country’s present-day electricity consumption would be met.

Australia has committed to reducing greenhouse gas emissions by 60 percent of year 2000 levels by 2050. Although an economic analysis of wave generation in Australian waters has yet to be carried out, Hemer says that wave energy offers a “massive resource” to contribute to the Australian Government’s aim of producing 45,000 gigawatt-hours/year of additional renewable energy before 2020. “Convert 10 percent of available wave energy from a 1000-km stretch in this area to electricity, ” Hemer says, and “the quota could be achieved by wave energy alone.”
