If Hermann Oelsner had his way, statuesque wind turbines would dominate the landscape of the Western Cape, breathing fresh air into South Africa's beleaguered power industry.If Hermann Oelsner had his way, statuesque wind turbines would dominate the landscape of the Western Cape, breathing fresh air into South Africa's beleaguered power industry.

The 5.2 megawatt project has been on hold for several months because of a row between the funding partners, but given it has taken Mr Oelsner a dogged 12 years to get this far, he seems unfazed by the latest hurdle.The 5.2 megawatt project has been on hold for several months because of a row between the funding partners, but given it has taken Mr Oelsner a dogged 12 years to get this far, he seems unfazed by the latest hurdle.
"Each turbine at full capacity can run 1,300 one-bar heaters per hour," the wind-power pioneer says, sitting in his office crammed full of old musical instruments and a small windmill wired up to an old-fashioned radio."Each turbine at full capacity can run 1,300 one-bar heaters per hour," the wind-power pioneer says, sitting in his office crammed full of old musical instruments and a small windmill wired up to an old-fashioned radio.
Compared to the national demand for power, he admits it is not much but he believes wind will eventually prove key to solving the country's energy crisis, which at one stage last year forced gold and platinum mines to shut down for several days.Compared to the national demand for power, he admits it is not much but he believes wind will eventually prove key to solving the country's energy crisis, which at one stage last year forced gold and platinum mines to shut down for several days.

Meanwhile, Eskom, which set up a 3.2 megawatt test wind plant seven years ago, has put on hold its first commercial 100 megawatt wind venture. It had been due to open next year in the Western Cape, but it has blamed the delay on the current economic downturn.Meanwhile, Eskom, which set up a 3.2 megawatt test wind plant seven years ago, has put on hold its first commercial 100 megawatt wind venture.

In its recent election manifesto, the ruling African National Congress said two years after the end of apartheid in 1996, 58% of the population had electricity. Today that stands at 80%, and it wants to attain universal access by 2014.In its recent election manifesto, the ruling African National Congress said two years after the end of apartheid in 1996, 58% of the population had electricity.

"No, it's not expensive," he remonstrates.
