- No wind, no electricity generated.
- Too high a velocity wind, no electricity generated as the turbines are stopped for safety reasons.
- Efficiency of wind generation in Australia is averaging 9 to 11%.
- Cost of coal and nuclear thermal generation is approximately $30 to $40 per megawatt hour.
- Cost of conventional gas thermal generation is approximately $48 per megawatt hour.
- Cost of wind generation is approximately $190 per megawatt hour Note: the above costs do not include transmission and distribution costs, carbon taxes or any utility surcharges.
- The vast majority of the location for wind turbines is away from existing transmission grids, thereby adding to the cost of delivery of power to the consumer.
- Power cannot be generated without wind blowing and the amount it can generate is dependent on how strong the wind is blowing.
- Can wind energy be stored economically? The basic answer is No!
- Can wind energy be stored at all? Yes, however:
a. The most convenient way to store wind power’s energy is to use the part time generation to pump water into hydro electricity dams; the green lobbies would most likely not want this and we may as well simply make new hydro dams without the wind....this would be cheaper.
b. Alternative storage can be achieved by installing massive battery banks somewhere in the system; again, high cost and perhaps defeats the “green” aspect of wind generation by manufacture of the batteries.
c. Research is being carried out to explore alternative storage but these are not likely, if at all, to be developed within the next 10 years.
- If we do nothing, and rely on wind power to replace new gas, coal, nuclear and other traditional generation, will widespread blackouts occur? Yes.
- Wind power is not economical - it is approximately double the cost of solar and 5 times the cost of traditional thermal generation. And that is not including its exorbitant manufacturing costs!
- Evidence is mounting that wind turbines create many health hazards and many consider them to visually pollute as well.
- Time Magazine and other media have extolled the virtues of Wind power. Journalists and media are not known worldwide for publishing the truth and unbiased information, nor do they, except in a few cases, have the technical or expert qualifications to report accurately and with balance. It is incorrect to advocate or insinuate wind can be relied upon to provide a reliable energy source 24/7 as suggested by Time magazine recently. Just because massive investments in Wind power have occurred does not prove it will replace traditional generation with or without subsidies....it certainly will not continue without subsidies!
Of interest is that solar generation, for domestic use in particular, can and is so often able to be located on the consumer’s roof or house, removing the cost of delivery. Further, Suntech (the world’s largest manufacturer of PV cells and using UNSW technology originally developed by Prof. Martin Green,) now claims efficiencies in its commercial production of greater than 19%. Suntech’s manufacturing costs are falling rapidly and product is sold in the retail market with a guarantee of a cost per kW hour at or less than 12 cents. Suntech’s publicly stated expectation is for price parity with the grid by 2015. Suntech has competitors with similar expectations. Wind power does not make any claims of grid parity in its process.
