Pointless struggle
'Struggle' to meet UK renewable targets
By Jonny Dymond BBC News |
Some doubt the ability of the UK to meet renewable energy targets |
"I remember having lunch on the sea front at Great Yarmouth, and watching a bank of windmills not turning for one hour, and I thought, please, please can we have some nuclear plants, before the lights go out," he told a recent meeting organised by the think tank Open Europe.
"It is not feasible," he added, "to diversify away from fossil fuel dependence to reduce carbon emissions so quickly, in pursuit of arbitrary, politically determined targets of questionable practicality."
The target, which the British government has signed up to, is part of a wider EU plan to increase renewable energy generation to 20% across Europe.
'Extremely challenging'
Under the scheme, Britain is expected to produce 15% of its energy from renewable sources within the next 12 years.
It's going to mean a national challenge Lord Freeman |
At present, says the Department for Energy and Climate Change (DECC), only 1.8% of Britain's energy is generated from renewable sources.
Much of the burden will have to be borne by wind power. A ten-fold increase in energy from on and offshore farms will be required by 2012.
"Extremely challenging" is how the House of Lord's European committee described the UK target in its report earlier this year.
The report is littered with clarion calls for urgent action on nearly every aspect of renewable energy generation. Lord Freeman, the chairman of the sub committee that drew up the report, fairly crackles with that urgency.
"It's going to mean a national challenge," he says. "If we are serious about greenhouse gases and climate change then renewable energy must be a contribution, and every single citizen has got to rise to that challenge, as well as the government."
Cost implications
The effort from individuals comes from energy efficiency, but perhaps also in accepting higher electricity bills - renewable energy currently costs more.
A tenfold increase in energy from wind power is required by 2012. |
Renewable energy may be cheaper in the long term, as fossil fuel prices rise again, and a lot cheaper if you take into account the costs of dealing with climate change.
Much of the burden for renewable energy will fall on wind power, because other renewable technologies are not mature enough or cannot be put in place quickly enough.
Many hurdles
Open Europe has grave doubts, it believes that as a method of cutting carbon emissions, extensive investment in wind farms simply does not add up.
It would be far cheaper, they say, to pay for the control of deforestation, or build "carbon sinks" through reforestation - or concentrate on energy efficiency to reduce demand.
The renewables target is pretty much a done deal now. But it faces many accusations that it is something for today's politicians to sign up to, and for tomorrow's politicians to fail to meet.
Renewables-sceptics say there are many hurdles to be jumped; the planning problems, the tight supply of turbines and off-shore equipment, access to the national grid.
Environmentalists have a response for each one. Dr Woolhouse says most of the obstacles can be overcome. But will the target be met?
"I don't really think it will. I think we are going to be very lucky to achieve our target, to be honest."
Energy policy 'too wind focused'
Energy policy 'too wind focused'
The CBI says the government targets wind power too much |
The current approach means the UK might miss climate change targets, it added.
The government said putting in place a balanced mix of renewables, new nuclear and cleaner fossil fuels was at the heart of its energy policy.
It is due to set out its Energy White Paper on Wednesday.
But the CBI is calling for more action in its report "Decision Time".
"The government's disjointed approach is deterring the private sector investment needed to get our energy system up to scratch, bolster security and cut emissions," said CBI deputy director general John Cridland.
"While we have generous subsidies for wind power, we urgently need the national planning statements needed to build new nuclear plants.
"If we carry on like this we will end up putting too many of our energy eggs in one basket."
Energy war
The CBI's comments are based on computer modelling of current power sector investment by consultants McKinsey.
The CBI wants the government to:
• reduce the percentage of wind power expected by 2020 under the Renewables Strategy later this week, to encourage investment in other low-carbon energy sources.
Roger Harrabin, BBC environment analyst The document is timed to influence the government's Energy White Paper due this week. It is the latest salvo in the business war between nuclear, coal and wind. A recent study by the consultants Poyry suggested that wind power could become so dominant in the UK that it leaves nuclear and CCS coal in competition with each other instead of holding the dominant position they have enjoyed since the 1950s. The McKinsey study projects that under 'business as usual' by 2030, gas would provide 36% of the UK's energy, coal 1%, wind 24%, nuclear 20%, other renewables 12%, and clean coal 8%. That would mean 64% of electricity would come from low-carbon technologies, behind the Climate Change Committee's 78% target. The investment cost is estimated at £125-£173bn.

• produce rules and funding arrangements for for Carbon Capture and Storage (CCS) demonstration plants
• accelerate investment in the grid
• improve energy efficiency in the electricity, heating and transport sectors, including offering financial sweeteners for consumers choosing more efficient products.
'No surprise'
A spokesman for the Department of Energy and Climate Change (DECC) said: "We know that big investments need certainty, and we're on track with our promise to remove costly unnecessary barriers to new nuclear, such as the planning reforms already in train."
Andrew Warren, director of the Association for the Conservation of Energy and formerly a member of the CBI's energy policy committee, told the BBC's environment analyst Roger Harrabin that the increase in wind power was threatening to the big power generators who he said dominated the committee.
"This document is no surprise. EDF have been lobbying very hard for less obligations on renewables, saying it will distract from nuclear," he said.
"This is precisely what Patricia Hewitt [the former trade and industry secretary] warned would happen when she published the 'no-new-nukes' 2003 energy white paper."
Irish Food gone
Swift action is needed "to halt the bee decline"
|
Three of the UK's 25 species are already extinct and more face the same fate unless fast action is taken.
Jim Fletcher of the Ulster Beekeepers' Association said it had been a very bad spring for the bees.
"It was a very bad April and May and the bees have not been able to forage as they require," he said.
"The bumble bees have had problems with late flowering and the queens haven't had the energy to build big nests for the production of their workers."
The bee problem had been ongoing for several years and was partly down to people having "nice tidy gardens, fields and hedgerows", said Mr Fletcher, who has about 500,000 bees in his County Down orchard.
A tiny mite had decimated the wild bee population in Northern Ireland, he said.
"This is to such an extent that we haven't got sufficient bees to pollinate the major fruit producing crops."
Bees help to pollinate every flowering plant.
"The possibility is that if we do not take sufficient care, that we may run into problems with food production."
Mr Fletcher advised people to "leave a few wild corners in their garden" to help the bees.
'Falling bee numbers'
Ulster Unionist environment spokesman Sam Gardiner called on all gardeners to grow more traditional local plants "to help reverse the decline in the bee population".
"Bees perform a vital role in the pollination of plants and are vital to eco-systems. Without bees, many native species of plants will disappear and this will have a knock-on effect on other species," he said.
"Many crops depend on bees for pollination and some, such as broad, field and runner beans are heavily dependent on them. Without the insects there would be little or no crop to harvest."
A new organisation - the Bumblebee Conservation Trust - has been launched with the aim of halting falling bee numbers.
Enthusiasts behind the trust, based at Stirling University, have urged as many people as possible to get involved.
As part of its conservation work, the organisation is encouraging the public to plant wildflowers, which provide nectar and pollen for bees and other wildlife.
Bees and flowers decline
See the bees |
They write in the journal Science that habitat alterations, climate change and modern industrial farming are possible factors in the linked decline.
There is a chance, they say, that the decline in pollinating bees could have detrimental effects on food production.
"The economic value of pollination worldwide is thought to be between £20bn and £50bn ($37bn and $91bn) each year," said Simon Potts from the University of Reading, UK, one of the scientists involved.
While declines in Britain and the Netherlands might not indicate a global trend, the team says, it is an issue deserving serious future research.
Costs of specialism
Study leader Koos Biesmeijer from the UK's University of Leeds is not the first biologist to note the value of amateur enthusiasts to British conservation studies, and will not be the last.
"We have relied here on records kept by enthusiasts; just like bird-watchers keep records of bird-sightings, they keep records of bees and hoverflies and plants," he told the BBC News website.
"In the UK, insect records come from the Bees, Wasps and Ants Recording Society (BWars) and the Hoverfly Recording Scheme (HRS), while in Holland the Dutch Entomological Society does something similar.
The ultimate drivers are changes in our landscapes; intensive agriculture, extensive use of pesticides, drainage, nitrogen deposition Koos Biesmeijer Pesticides blame for bee fall |
Bee species which rely on certain plants, and plants which rely on certain bees, have fared worse; more flexible species of both have done better.
In Britain, bee species which have increased since 1980 are those which were already common before.
The researchers also looked at hoverflies, and found a mixed picture, with diversity remaining roughly constant in Britain but appearing to increase marginally in the Netherlands.
Hoverflies do pollinate plants, but are less choosy than many bee species, and do not depend so directly on nectar to feed their young.
Overall, plants which pollinate via wind or water appear to be spreading, while those which rely on insects decline.
Holistic handling
If the diversity of bees and plants is decreasing, one question is: which declined first?
This study cannot provide an answer, though it appears the fates of both are intertwined; but the root causes of the decline are clear, Dr Biesmeijer argues.
"The ultimate drivers are changes in our landscapes; intensive agriculture, extensive use of pesticides, drainage, nitrogen deposition.
"All of these factors favour subsets of plants and subsets of bees.
"And if you want to prevent them you have to look at the ecosystem level, protecting the habitat and the groups of species."
Where habitats have been restored, for example under agro-environment schemes, bee and plant diversity has sometimes started to re-emerge, he said.
While such changes may have significant impacts nationally, the team points out that the environments of Britain and the Netherlands, with their high population densities and long histories of agriculture, contain two of the least "natural" landscapes on Earth.
Other countries, with a greater proportion of natural habitat, may not show the same declining trend, they say; but given the importance of bees for pollination, they suggest it would be worth finding out.

Help call for vanishing honeybees
Bees have been hit by disease, climate change and pesticide use

It wants Defra to spend more money on research into bee health and make registration compulsory for beekeepers.
Environment Secretary Hilary Benn said £10m had been earmarked to analyse the decline of pollinators, including bees.
But the PAC wants the government to ring-fence that money for honeybees alone and not allow it to be diluted by looking at other pollinating insects.
'Colonies lost'
The government says bee numbers have fallen by up to 15% in the last two years, in part because agricultural changes have reduced the availability of the wildflowers they depend on for food.
Disease, climate change and pesticide use have also been blamed for the decline.
Honeybees and other pollinators are absolutely vital to producing our food

Given their value to the economy, he said it was "difficult to understand why Defra has taken so little interest in the problem up to now".
Registration is currently voluntary for beekeepers, but the PAC says making it compulsory would allow Defra to deliver advice on bee husbandry to far more people.
Mr Benn said: "Honeybees and other pollinators are absolutely vital to producing our food.
"Defra is providing financial backing for a £10m research initiative into pollinator decline, including honey bees, with decisions on projects to be made in the coming months."
The British Beekeepers Association has backed the PAC's call for research spending to be ring-fenced

pirates Somalia
Turkish ship seized off Somalia
Somali piracy has become a major international issue |
A Turkish cargo ship with 23 crew on board has been seized by pirates off the coast of Somalia.
Istanbul-based Horizon Shipping said pirates in speed boats had surrounded the Horizon I vessel in the Gulf of Aden at about 0530 GMT.
Three attackers managed to board the tanker, which was heading from Saudi Arabia to Jordan, the firm said.
Maritime officials believe pirates in Somalia are now holding 12 ships, with about 200 crew, for ransom.
The country has been without a functioning central government since 1991, allowing pirates to operate almost uninhibited in one of the world's busiest shipping lanes.
In this season it is hard to take ships because monsoon winds make the seas rough. No-one expected attacks at this time Negotiator Andrew Mwangura |
Omer Ozgur, from Horizon Shipping, said the Horizon I was continuing on its course despite the hijack.
The pirates have not yet issued any demands or contacted the firm.
Andrew Mwangura, of the East African Seafarers' Assistance Programme, which works to free ships, said the attack came as a surprise.
"In this season it is hard to take ships because monsoon winds make the seas rough. No-one expected attacks at this time," he told Reuters news agency.
Earlier, Nato spokesman Commander Chris Davies told the BBC's Network Africa programme that pirates in the Gulf of Aden were having less success this year compared with last year.
But he said Nato, which has an anti-piracy task force off the Horn of Africa, wanted the legal apparatus in place in Africa to deal with the pirates if they were caught.
"If we capture the pirates we're not looking to take them all the way back to, say, America or Turkey," he said.
Earlier in June the EU, which co-operates with Nato in the region, agreed to extend its anti-piracy operation there until the end of 2010.
Two dozen ships from European Union nations, including Britain, France, Germany and Italy, patrol an area of about two million square miles.
