Talks aim for cross-border protection of birds of prey

Some 51 per cent of African-Eurasian migratory raptor species have an "unfavourable" conservation status.
John O'Sullivan, of Birdlife International, a global alliance of conservation organisations, said: "We have recently heard about the sad case of the golden eagle being poisoned in Scotland, but birds of prey face additional problems trying to settle in networks of suitable habitats along their migration paths. We know little about the status of raptors in Africa, and in Asia species are poorly understood." The main threats to the birds, Mr O'Sullivan said, were habitat loss, illegal hunting, power lines, and wind farm initiatives.
No easy options on renewable energy sources

Wind power is a mature technology, used widely in Europe. In Germany it produces 20 000MW. ...Unfortunately, South Africa is not the best location; there is just not enough wind to generate sufficient sustainable electricity supply. ...
To generate large amounts of electricity from wind turbines would require large tracts of land. A wind turbine that generates 5MW could have a 12m diameter. In comparison, an Airbus A380's wingspan is 80m. So to generate a large amount of power, say Koeberg's capacity of 1 800MW, you would need about 380 5MW wind turbines. ...Wind will be a small part of South Africa's future energy mix. Solar power holds more promise as an environmentally friendly solution to South Africa's energy crisis.
When Rudolph Diesel unveiled his new engine at the 1900 World's Fair, he made a point of demonstrating that it could be run on peanut oil. "Such oils may become, in the course of time, as important as petroleum and the coal tar products of the present time," he said.
And so it has come to pass that US President George Bush has decreed that America must wean itself off oil with the help of biofuels made from corn, sugar cane and other suitable crops.
At its simplest, the argument for biofuels is this: By growing crops to produce organic compounds that can be burnt in an engine, you are not adding to the overall levels of carbon dioxide in the atmosphere.
The amount of CO2 that the fuel produces when burnt should balance the amount absorbed during the growth of the plants.
However, many biofuel crops, such as corn, are grown with the help of fossil fuels in the form of fertilisers, pesticides and the petrol for farm equipment.
One estimate is that corn needs 30 per cent more energy than the finished fuel it produces.
Another problem is the land required to produce it. One estimate is that the grain needed to fill the petrol tank of a 4X4 with ethanol is sufficient to feed a person for a year.
Japanese govt plans 600MW wind project in Patagonia - Argentina

January 6, 2007 in Business News Americas
Japan’s government has presented a 600MW wind power generation project for the Patagonia region to Argentina’s energy secretary Daniel Cameron, Argentine government news agency Telám reported.
The prospective plant will call for the installation of 200 wind turbines with 3MW generation capacity each, covering northern Santa Cruz to southern Chubut province.
The Japanese government wants a Japanese firm to construct the turbines; possible candidates include Nissan, Honda and Toyota.

Indigenous people see harm from Kyoto warming pact

Indigenous peoples from the Amazon to Asia said on Wednesday that U.N.-backed clean energy projects meant to combat global warming were aggravating threats to their livelihoods.
They said hydropower projects or plantations of fast-growing trees, prompted by a billion-dollar scheme under the U.N.’s Kyoto Protocol for limiting the planet’s dependence on fossil fuels, were damaging nature.
“We are not only victims of climate change, we are now victims of the carbon market,” Jocelyn Therese, a spokesman for indigenous peoples of the Amazon basin, told a news conference on the fringes of U.N. talks on global warming.
“Efforts that are supposed to…retard climate change are having an equally disastrous effect,” said Ana Pinto, representing indigenous peoples in India.
A World Bank scheme to bring electricity to the world's poor is short-sighted and won't curb climate change or help the people it's aimed at, environmental groups said on Sunday.
The Bank released a progress report on Sunday looking at ways to fund cleaner energy projects in some of the world's poorest regions and drive economic growth in those areas.
The report, entitled Investment Framework on Clean Energy and Development, says an estimated 1.6 billion people do not have access to electricity.
Environmental groups said the Bank was missing a huge opportunity to promote the use of renewable energy by instead backing conventional fossil-fuel based generation.
Brazil's renewable power incentive program Proinfa has stalled because of lack of financing and equipment, Romulo Feijão, an aide to the generation supervision department at power regulator Aneel told BNamericas.

"Wind power is unfortunately not the holy grail of electricity supply for the future. Despite this energy source, wind, being free, the very high capital investment required and the high maintenance costs result in high generating costs."

Until recently, Europe's small market in biofuels was dominated by home-grown rapeseed (canola) oil. But surging demand from the food market has raised the price of rapeseed oil too. This has led fuel manufacturers to opt for palm and soya oil instead. Palm oil prices jumped 10 per cent in September alone, and are predicted to rise 20 per cent next year, while global demand for biofuels is now rising at 25 per cent a year.
But world energy resources are adequate to meet this sustained growth trend because global oil reserves today exceed the cumulative projected production to 2030, IEA said. This optimistic outlook, however, is based on a reference scenario that IEA describes as "unsustainable."
Under that reference scenario, primary world energy demand increases by an average rate of 1.6%/year, with fossil fuels accounting for 83% of the projected increase. By 2030, the world consumes 16.3 billion tonnes of oil equivalent (toe)/year5.5 billion toe more than it does todaywith more than two thirds of energy use coming from developing countries.
