Farmers in the European Union could face quadrupled costs - and people will ironically run greater safety risks - if a proposed new standard for electric fence energizers is adopted.
A French and a German manufacturer are pushing for the maximum power of electric fence energizers to be reduced to 5 joules across 28 European countries.

The same proposal was rejected overwhelmingly by the International Electrotechnical Commission subcommittee for farm electrical appliances, when it last met at Sydney in November 2004.
However, it is now before the European Committee for Electrotechnical Standardization (CENELEC). It is expected to go to a paper vote shortly, but without Europe's farmers being consulted first.
The move is seen as a bid to block competition from medium to high-powered energizer technology from New Zealand and other countries.
Gallagher and Tru-Test, of New Zealand, are major players in the world and European electric fence markets and both are now lobbying hard to avoid the proposed new trade barrier.
New Zealand's Federated Farmers organisation is warning its European counterparts that if the move to introduce a technical barrier to trade succeeds under a "safety guise", then all farms larger than 30 acres will not be able to operate electric fences from a single energizer source.
According to Gallagher, a world leading electric fence technology company of Hamilton, New Zealand, the proposed new standard would increase the cost of installing energizers and solar panels on a 200 acre European farm from 1135 euros to 4500, a 400% rise. This does not count significant labour costs.
"It's obvious why some have launched this sneak attack to change the standards," says Gallagher Group CEO Bill Gallagher. "Some want to sell more of their out-of-date technology."
And he warns that any lowering of fence power will actually create greater safety risks, both on and off the farm:
. A 5-joule energizer would require a 200-acre farm to be divided
into four zones, with at least four energizers to give equivalent containment in all seasons.
. Lower energizer power would increase the risk of more stock
getting onto roads
Gallagher says during 2002 in Germany alone there were nine deaths and 308 serious injuries caused by traffic accidents with non-feral livestock on roads.
"Some of these stock-on-road related accidents could have been prevented by more effective electric fences. There have been no deaths caused directly by electric fences recorded in Germany in the past 10 years."
Gallagher says 9-joule energizers were introduced 26 years ago and more than 300,000 are installed around the world. Ten years ago a 26-joule energizer was introduced and more than 26,000 are in service. Almost one third of these are in use in Europe.
"These ultra high powered energizers have a perfect safety record. Imagine if everyone had to replace them because it suddenly became illegal to have anything above five joules. It would be hugely costly to European farmers," Gallagher says.
New Zealand Federated Farmers' national president Charlie Pedersen has written to leaders of farmer organisations in Europe warning them of the proposed change.
He urges them to lobby the electrotechnical committees in their own countries.
"It seems to me the 30 year-old technology you will be forced to adopt closely relates to the systems the French market in Europe now," Pedersen says. "As a fellow farmer I know the economic benefit the new higher powered energizers have brought to my farm. We now have only one energizer that has replaced four older (ones) and keep all cattle controlled with a single wire, in a pastoral feeding situation."
He says it's "sad" that most CENELEC country-based committees will be voting on the issue later this year, or early in 2006, "without any farmer organisation input".
