    A report commissioned by Commons authorities into the Houses of Parliament’s use of bottled water found that it uses over 21,000 bottles of water each year, resulting in a carbon footprint of 12 tonnes.



     


    The study, carried out by environmental consultants Best Foot Forward, was not published but was leaked to the Evening Standard.


    It revealed that each year 10,000 bottles of sparkling and 11,400 bottles of still water are used in Parliament, while the associated delivery lorries have clocked up more than 70,000 miles over five years.


    A blog posting by Best Foot Forward confirmed the findings of the report.


    “The study, which quantifies the life cycle emissions of several different options, found that bottled water performed the worst – and that savings of 11tCO2 per year were possible through a switch to tap water,” it said.


    However, the Commons Administration Committee controversially decided last year that it would offer only bottled water in meetings.


    The revelations will be especially damaging to MPs, some of whom have campaigned against bottled water.


    Last year, government minister Phil Woolas told the BBC that consumers should switch from bottled to tap water whereever possible. “It borders on morally being unacceptable to spend hundreds of millions of pounds on bottled water when we have pure drinking water, when at the same time one of the crises that is facing the world is the supply of water,” he said.


    US studies have found the total energy required for bottled water production was as much as 2,000 times the energy cost of producing tap water.

  • Biomass: Another Renewable Energy Source

    Posted on August 26, 2009


    Biomass: Another Renewable Energy Source


    Today’s posting comes from AltaTerra Research’s principal analyst in “green data centers.” Data centers are responsible not only for giving you your email, web browsing, credit card transactions and views of your friends’ photos, but also a growing amount of energy use–on a par with the airline industry. In today’s post, Dr. Zen Kishimoto ponders the possibility of biomass powered data centers.


    I have covered renewable energy sources, namely wind, solar, and geothermal, in previous blogs.



    The Energy Information Administration (EIA) has reported the power generation breakdown among renewable energies and their distribution, as shown in the figure below.


    The EIA report separates wood and wood type from other biomass. Other analyses, such as Wikipedia’s, combine this type with the rest of biomass.



     


    Biomass, a renewable energy source, is biological material derived from living, or recently living organisms,[1] such as wood, waste, and alcohol fuels. Biomass is commonly plant matter grown to generate electricity or produce heat. For example, forest residues (such as dead trees, branches, and tree stumps), yard clippings and wood chips may be used as biomass. However, biomass also includes plant or animal matter used for production of fibers or chemicals. Biomass may also include biodegradable wastes that can be burnt as fuel. It excludes organic material such as fossil fuel which has been transformed by geological processes into substances such as coal or petroleum.


    Renewable Energy Power Generation Breakdown


    Power generated by each renewable energy source in 2008 (thousands of MWh)


    In my previous blog, I noted that there are more solar-powered data centers than wind-powered ones. But in reality, wind generates more power than solar and appears to be suitable for powering data centers. This observation is reinforced by the EIA breakdown, which shows that there is more than 30 times as much wind power as solar. Biomass generates about half the power that wind does. And if the wood and wood-type category is combined with the rest of biomass, then the power generated will be more than that by wind (52% vs. 33%).


    What about using biomass power for data centers? I searched for some examples of biomass-generated power for data centers, but I could not find many. Rich Miller of Data Center Knowledge reports in his blog that Emerson has installed a 100 kW solar panel array on its data center. In the comment section, someone mentioned the availability of power generated by biomass, as 20 tons of biowaste produces 3 MWh a day. In another of Miller’s blogs, I found another example of the power generated by biomass for Internet Villages International (IVI) in Scotland. Plans call for the IVI data centers to use electricity from a nearby biomass plant at Steven’s Croft operated by E-On UK (Powergen) and local wind farms. Local weather makes the area a prospect for using outside air to cool the servers (air-side economization). Waste heat from the data center buildings may be used to heat a nearby residential development.


    Meanwhile, my wife and I are producing three piles of biomass, a.k.a. compost, in our backyard. By recycling our waste, we cut down substantially on the amount of garbage we produce. However, we have found that doing this requires a lot of water. Although we are not generating power from this, I wonder how much water the generation of biomass consumes. I wrote on the shortage of water before.

  • Langlee Wave Power And Unmaksan To Build 24-MW System

    Langlee Wave Power And Unmaksan To Build 24-MW System


    Oslo, Norway [Hydro Review]

    Turkish energy company Unmaksan and Norwegian energy company Langlee Wave Power have signed a deal to build a 24-MW wave power system off the coast of Turkey. The exact location has not been determined.



    The first phase of the project calls for a 120 KW pilot facility, which will eventually be developed into a 24-MW system comprised of 200 wave energy converters designed by Langlee.

    “Unmaksan has analyzed more than 70 different wave power concepts, and we believe Langlee has the most robust technology and cost-effective solution,” Unmaksan Managing Director Serhat Kan said in a news release.





    The US$169 million project will be built close to the shoreline in shallow waters near existing distribution systems, the companies said. Unmaksan will build the project and Langlee owns the licensing rights to the technology. Langlee said it expects to receive US$14.7 million in licensing fees from the project.

    Earlier this year, the World Bank approved US$600 million in financing for Turkey’s Private Sector Renewable Energy and Energy Efficiency Project. (HydroWorld 7/10/09) Contractors, consultants, and project sponsors have been encouraged to participate in the development of renewable energy projects, including hydropower

  • Coal aid rides high above wave power

    Coal aid rides high above wave power


    Amount invested in marine energy is a drop in the ocean against more than £50m for collieries


     





    The government has spent 20 times more subsidising the coal industry over the past six years than it has put into marine energy, new figures show.


    Ministers have given away £52.8m of a £60m coal investment aid scheme to extend operations at a range of mines around Britain, including Daw Mill in Warwickshire where energy minister Mike O’Brien is the local MP. This contrasts with the £2.3m handed out from a £50m pot created under the Marine Renewables Deployment Fund, which started in 2004 just 12 months after the launch of the latest coal scheme.


    “At a time when we need to deliver a major expansion in renewable energy, it’s astonishing to find that less than 5% of the investment promised to give Britain a lead in marine energy has actually been made,” said Greg Clark, shadow energy and climate change secretary.



     


    “It is little wonder that Britain punches way below its weight on renewables – we have the third-lowest contribution from renewable energy in Europe, despite some of the best resources.”


    The Observer revealed last month that ministers had spent almost nothing out of the Marine Renewables Deployment Fund, with potential users complaining the conditions attached to grants were so onerous that they could not gain access.


    The amount of cash handed out under the coal aid scheme was recently revealed in parliament and the Conservatives say that all of it – bar one grant – has been spent in Labour constituencies.


    The government has sought to make up lost ground, with money being promised in the recent energy white paper to various tidal and other schemes. More than £20m has been earmarked for a new Marine Renewables Proving Fund with a further £9.5m going to develop a Wave Hub off Cornwall and £8m for a European Marine Energy Centre in Orkney.


    But the Tories argue that ministerial promises mean very little. “It is easy to talk about support for renewables but what we need is action,” said a spokeswoman. The opposition says it would use the money from the Marine Renewables Deployment Fund to establish a network of large-scale marine energy parks to be run on a commercial basis.


    When the coal subsidies were launched in 2003 by the then trade and industry secretary, Patricia Hewitt, the main emphasis was on job retention.


    Last night a spokesman for the Department of Energy and Climate Change said it was not helpful to compare two completely different technologies – coal having been in development for generations, and marine very much cutting edge.


    He added: “We want to be a global leader in wave and tidal energy, that’s why we announced £60m of low carbon investment funding in the budget. That included £22m to help pre-commercial testing of marine technology, which should enable access to the Marine Renewables Deployment Fund.”

  • Shell and BP keen to buy into Tullow’s new oil find in Uganda

    Shell and BP keen to buy into Tullow’s new oil find in Uganda


    Tullow needs cash to fund development of pipelines and infrastructure

    The world’s biggest oil companies – including BP and Shell as well as state-owned operations from China – are trying to muscle their way into the world’s largest new oil region: Uganda.


    Tullow Oil, the relatively small British-based firm at the centre of the huge energy strikes in Lake Albert, says it plans to hand over part of the oil riches in return for financial help to build pipelines and other vital infrastructure.


    Excitement over the Ngara wells increased when Tullow reported it had encountered further shows of oil and was more convinced than ever about the enormous prospects in the region.



     


    But the company also announced an 83% slump in first-half profits to £21.4m and a 16% drop in its existing production from the North Sea and elsewhere, while needing billions of pounds to bring oil out of the ground and refine it in Uganda.


    “It is not every day you find a new oil province similar in size to the central Graben region of the North Sea. Practically all the oil majors and some national oil corporations have been on our doorstep seeking to pre-empt a competitive [sales] process”, said Angus McCoss, Tullow’s exploration director.


    Tullow plans to sell part of its 100% stake in Block 2, one of three blocks which cover the Ugandan side of Lake Albert, in the next 12 months, it said, but only through a public offer and not via a bi- lateral deal with one other company.


    Among the possible partners is Eni of Italy which has already been tipped as a potential buyer of the whole Tullow company although the British firm said it was clearly not for sale.


    Tullow shares fell 4% to 1052p on profit-taking following a period where euphoria around the Uganda exploration success has driven the value of the stock up by nearly a third in value since early July.


    McCoss said 700m barrels of recoverable reserves had already been proved up but the latest oil shows put the company on the way to proving that there was a further 1.5bn waiting to be exploited.


    Tullow said Eni, which has a 43% stake in pipeline builder Saipem, would be a suitable partner as would Chinese companies and others but insisted there was currently no favoured partner in mind.


    Tullow said its Ngassa-2 well in Block 2 found signs of oil at two intervals in the reservoir being tested.


    “The pressures in these intervals are higher than normal, which may indicate that they are associated with significant oil columns,” it added.


    Investment bank Citigroup said in a research note that the results of the latest well would pave the way for a part sale of the block as it makes clear how much it is worth.


    The Ugandan government has made clear to Tullow that it would like the company to refine the oil in the area so that the relatively impoverished country could gain as much added value from the energy as possible.


    The African country is also acutely aware that many developing countries have found oil riches can be curse as well as cure with charities warning it can bring corruption and wealth only for the political elite. Nigeria is often held up as an example of this.

  • Water shortage threatens two million people in southern Iraq

    Water shortage threatens two million people in southern Iraq


    Electricity supply to Nasiriyah has dropped by 50% because of falling levels of Euphrates river









    Two million people face life without water Link to this video


    A water shortage described as the most critical since the earliest days of Iraq‘s civilisation is threatening to leave up to 2 million people in the south of the country without electricity and almost as many without drinking water.



     


    An already meagre supply of electricity to Iraq’s fourth-largest city of Nasiriyah has fallen by 50% during the last three weeks because of the rapidly falling levels of the Euphrates river, which has only two of four power-generating turbines left working.


    If, as predicted, the river falls by a further 20cm during the next fortnight, engineers say the remaining two turbines will also close down, forcing a total blackout in the city.


    Down river, where the Euphrates spills out into the Shatt al-Arab waterway at the north-eastern corner of the Persian Gulf, the lack of fresh water has raised salinity levels so high that two towns, of about 3,000 people, on the northern edge of Basra have this week evacuated. “We can no longer drink this water,” said one local woman from the village of al-Fal. “Our animals are all dead and many people here are diseased.”


    Iraqi officials have been attempting to grapple with the magnitude of the crisis for months, which, like much else in this fractured society, has many causes, both man-made and natural.


    Two winters of significantly lower than normal rainfalls – half the annual average last year and one-third the year before – have followed six years of crippling instability, in which industry barely functioned and agriculture struggled to meet half of subsistence needs.


    “For thousands of years Iraq’s agricultural lands were rich with planted wheat, rice and barley,” said Salah Aziz, director of planning in Iraq’s agricultural ministry, adding that land was “100% in use”.


    “This year less than 50% of the land is in use and most of the yields are marginal. This year we cannot begin to cover even 40% of Iraq’s fruit and vegetable demand.”


    During the last five chaotic years, many new dams and reservoirs have been built in Turkey, Syria and Iran, which share the Euphrates and its small tributaries. The effect has been to starve the Euphrates of its lifeblood, which throughout the ages has guaranteed bountiful water, even during drought. At the same time, irrigators have tried tilling marginal land in an attempt for quick yields and in all cases the projects have been abandoned.


    “Not even during Saddam’s time did we face the prospect of something so grave,” said Nasiriyah’s governor, Qusey al-Ebadi. Just east of the city, the Marsh Arabs are also on the edge of a crisis – unprecedented even during the three decades of reprisals they faced under the former dictator.


    “The current level of the Euphrates cannot feed the small tributaries that give water to the marshlands,” he continued. “The people there have started to dig wells for their own survival. There is no water to use for washing, because it is stagnant and contaminated. Many of the animals have contracted disease and died and people with animals are leaving their areas.”


    Nowhere is Iraq’s water shortage more stark than in what used to be the marshlands. Towards the Iranian border and south to the Gulf, rigid and yellowing reeds jut from a hard-baked landscape of cracked mud.


    Skiffs that once plied the lowland waters lie dry and splintering and ducks wallow in fetid green ponds that pocket the maze of feeder streams. Steel cans of drinking water bought by desperate locals line dirt roads like over-sized letter boxes.


    The Euphrates, once broad and endlessly green, is now narrow and drab. In parts it is a slick black ooze, fit only for scores of bathing water buffalo. Giant pumps lay metres out of reach. Some are rusting. “Not long ago, the level of the Euphrates was at this rust line,” said Awda Khasaf, a local leader in the al-Akerya marshlands, as he pointed at the dwindling river.


    “It has now dropped more than 1.5m. This river feeds all the agriculture lands and marsh lands in Nasiriyah. It smells like this because it is stagnant,” he said. “We turned to agriculture in 1991 after Saddam’s rampage, but now the government has ordered us to stop rice farming.”


    Further up the river Sheikh Amar Hameed, 44, from Abart village said: “We have lost the soul of our lives with the vanishing water. We have lost everything. We are buying drinking water now. The government must find a solution. The young will all become thieves. They have no prospects.”


    Iraq’s water minister, Dr Abdul Latif Rashid, this week estimated that up to 300,000 marshland residents are on the move, many of them newly uprooted and heading for nearby towns and cities that can do little to support them.


    The Marsh Arabs are semi-nomadic and large numbers have remained displaced since Saddam drained the marshes in 1991.


    “In the last 20-30 years our neighbouring countries have built a number of structures for collecting water or diverting water for their agricultural lands,” Dr Rashid said.


    “In some cases, they have diverted the path of the river for their internal use. This has had a very damaging effect. We have a large number of branches of the Tigris that we share with Iran. In most their volumes are low, or completely dried up. In 2006/07 [the marshlands] almost reached 75% of original levels. Now the surface water is around 20%. Water resources have this year become not only serious, but critical. Iraq has not faced a water shortage like this.”


    Officials have tried to compensate by digging wells and bores, especially in the ravaged provinces of the south and in Anbar, west of Baghdad. Delegations have also travelled to Turkey and Syria, where they were warmly received, but have achieved few changes. “We were expecting much more of a release from Turkey,” Dr Rashid said. “Iran has been less receptive. We have had no response from them at all.”


    River wars


     


    Nile Nine Nile basin countries are in dispute over water-sharing. Countries including Uganda and Rwanda are attempting to overrule a 1959 treaty that restricted building on the river without Egypt’s consent. Egypt is reliant on the volume of water it currently receives.


     


    Euphrates Iraq and Syria oppose the building of dams on the river by Turkey. Iraq is reliant on the river for irrigation, and damming upriver seriously affects water flow.


     


    Jordan Israel and Palestine share a water aquifer along the West Bank, but Palestinians only have access to one fifth of the water held there. They are also in dispute over the river Jordan, with Israel claiming 90% control.


     


    Indus Pakistan is in dispute with India over the Indus river that supplies water to millions. Reservoirs and dams have caused water shortages in downstream areas, such as Karachi. A presidential decision to provide more water to the population in Sindh by closing the Tarbela Dam also caused outrage in neighbouring Punjab, whose water was being diverted.
