SLEAFORD has become one of the first towns in the country to see its historic parish church fitted with solar power.
St Denys' Church has just taken delivery of 56 solar panels from Germany which are being fitted to the roof of the south nave by a team of expert engineers.
The £56,000 project will save 4.5 tonnes of CO2 emissions and generate 900KW or £1,300 worth of electricity a year in an effort by the church to do its bit for the environment and cut out greenhouse gases.
The project has been led by curate, the Rev Jeremy Cullimore who said that they were now looking at using some of the energy generated to heat the church, the rest will be sold to the National Grid.
He said: "This is the start of the project. Getting the panels has been a challenge and getting the funding has been a challenge, but we are going to save four-and-a-half tonnes of CO2 emissions a year. To get this on a Grade 1 listed church has been a real challenge, but also an opportunity because we can show here what we ought to be doing to protect out environment and save emissions, working with God given light that we can use to power out modern lifestyle."
The large panels, which are aluminium frames holding toughened glass backed with bulletproof Kevlar, are fixed to a system of racking to protect the lead roof. Cables run in through a window to a pair of convertors transforming the power from DC to AC current.
The Rev Cullimore added: "In Sleaford we are really cutting edge and leading the way. If more churches in Lincolnshire could do this the effect on our national energy consumption would be significant. We have set a precedent and a lot of other churches are looking at it with some enthusiasm."
The eastern side of England naturally gets more sunshine, ideal for solar power, but he now wants to arrange a conference for clergy to discuss the many ways of saving and generating green energy. He saw every school and local government office could be treated in the same way.
English Heritage had had concerns about how the panels may affect the views of the church but have been convinced to allow it to go ahead.
They cannot be seen from anywhere in town except for the top of The Hub.
The solar panels should be long-lasting as well, with similar equipment having been used on North sea buoys for over 20 years.
Having had to carry the large panels up scaffolding by hand, workmen, employed by a Lincolnshire-based company, Freewatt, should have the job completed within two weeks. Work had been delayed while rotten guttering was replaced at an additional cost of £16,500.
Half the funding for the scheme has come from a Government green energy grant while another 45 per cent was paid out by the BIG Lottery Fund and the remainder from church funds.
He said The Rev Cullimore said the parochial church council and Canon John Patrick have been totally supportive.

Solar Power Partners Helps LA Go Green
Solar Power Partners has officially announced that several of its solar energy facilities in the Los Angeles area are in full commercial operation and generating electricity.
The solar energy facilities include a 238.68 kW system at the California Institute of Technology (Caltech) in Pasadena; a 601.02 kW system at BT's North America corporate headquarters offices in El Segundo; and Safeway Inc.'s Vons grocery stores in Monrovia (230.09 kW), Oxnard (187.53 kW), Corona (204.82 kW), and Murrieta (198.17 kW).
Each solar facility was financed and developed using a solar Power Purchase Agreement (PPA), a long-term energy financing solution that helps customers go green without the hassles or costs of solar facility ownership, operations, or maintenance.
A solar PPA allows SPP's host customers to pay only for the energy produced by the system, while SPP, alone and/or through its subsidiaries, develops, operates, and maintains the system for the length of the agreement, usually over twenty years. SPP's host customers can enjoy predictable energy rates for the life of their agreement.
"Thanks to our partnership with Solar Power Partners, BT is now not only significantly reducing carbon emissions - we're realizing reduced power costs for our site as well as helping our company fulfill its very ambitious corporate social responsibility goals," said Jon Reiter, Senior Director, Major Transactions, BT Americas.
As noted by Bill Irwin, Senior Director of Facility Management at Caltech, "SPP's experience making solar power attainable for schools and universities makes for a great long-term partnership."
"SPP is proud to be a part of solar energy initiatives by leading corporations and universities in the greater Los Angeles Area, the regional market with possibly the greatest potential for distributed commercial solar applications throughout America. Our projects with Caltech, BT, and Safeway are excellent examples of how solar Power Purchase Agreements enable entities to embrace solar energy without any of the operational hassle of owning a power plant," said Alexander v. Welczeck, President and CEO, Solar Power Partners.
SPP's dedicated asset management team operates each facility using web-based monitoring technology, which provides performance data every 15 minutes and operation alerts as necessary. SPP manages all aspects of preventative maintenance and repairs when needed.
The Caltech solar system features a 238.68 kW sized fixed rooftop array on the Holliston parking garage. The system's estimated annual solar-generated electricity eliminates 527,000 pounds of CO2 emissions from the air, which is equivalent to removing 46 cars from operation, planting 72 acres of trees, or powering 38 average homes annually.
The system at BT's office building in El Segundo is a 601 kW fixed rooftop and elevated system, including a tracking system over the main parking lot. The tracking modules move during the day to follow the sun, thereby increasing energy production.
The system is expected to generate approximately one million kilowatt-hours (kWh) of renewable electricity each year, which will reduce carbon emissions by 700,000 pounds (more than 316 metric tons) annually, helping the company fulfill its global goals for sustainability.
The four Safeway stores in Monrovia, Oxnard, Corona, and Murrieta total 820.61 kW in size, and are all fixed rooftop systems.
Combined, these systems are estimated to produce enough solar-generated electricity to eliminate 973 metric tons of CO2 emissions from the air, or to power 88.5 average homes annually, according to the US Environmental Protection Agency calculator.
Financing of the solar facilities was partially provided by Bank of America in the form of a tax equity investment and Energy Investors Funds through their United States Power Fund III, L.P.

Solar Modules Installed On European Court Of Justice
Kyocera has announced that the European Court of Justice, officially known as the Court of Justice of the European Communities, has installed Kyocera solar modules on its new building.
As one of the leading manufacturers of photovoltaic systems for more than three decades, Kyocera produces its solar modules without procuring any semi-finished components in its fully integrated production process, thus ensuring quality at every stage of manufacturing.
Quality was the decisive factor in installing a photovoltaic system composed of Kyocera solar modules at the European Court of Justice in Luxembourg. The roof of the new building will be lined with 2,262 KC175GH-2P modules with a total capacity of 400 kWp, and the system is expected to generate an estimated 360,000 kWh annually.
By using this environmentally-friendly energy source the court facilities will be contributing to the reduction of CO2 emissions. The installation of the system was completed in December 2008.
"We are proud that the roof-mounted system at the European Court of Justice will be equipped with Kyocera modules," stated the President of Kyocera operations in Europe, Mitsuru Imanaka.
"The confidence shown in our products adds further impetus in our continual pursuit for superior quality. While aiming to achieve this, we are driven by our resolve to develop environmentally-friendly products and technologies that provide both environmental and economic advantages."
Kyocera is a pioneering company in the solar energy industry which first began developing solar cells in 1975. Over 30 years of experience have allowed the company to master all stages of production at the highest level - from processing raw materials, making wafers and solar cells to module installation.
The result of Kyocera's years of experience and fully integrated production process is superior quality and long product life.
Kyocera has also started construction of a new production facility for solar cells in Shiga Prefecture, Japan, which will contribute to achieving plans to increase the cell production output from the current 300 Megawatts per year to 650 Megawatts per year by 2012.

Carbon cuts 'only give 50/50 chance of saving planet'
As states negotiate Kyoto's successor, simulations show catastrophe just years away
By Michael McCarthy, Environment Editor
The world's best efforts at combating climate change are likely to offer no more than a 50-50 chance of keeping temperature rises below the threshold of disaster, according to research from the UK Met Office.
The key aim of holding the expected increase to 2C, beyond which damage to the natural world and to human society is likely to be catastrophic, is far from assured, the research suggests, even if all countries engage forthwith in a radical and enormous crash programme to slash greenhouse gas emissions – something which itself is by no means guaranteed.
The chilling forecast from the supercomputer climate model of the Met Office's Hadley Centre for Climate Prediction and Research will provide a sobering wake-up call for governments around the world, who will begin formally negotiating three weeks today the new international treaty on tackling global warming, which is due to be signed in Copenhagen in December.
The treaty, which is due to replace the 1997 Kyoto Protocol, is widely seen as the Last Chance Saloon for the community of nations to take effective action against the greatest threat the world has ever faced. But the Met Office's new prediction hits directly at the principle guiding all those hoping for an effective agreement, with the European Union in the lead: that of stopping the warming at two degrees Centigrade above the "pre-industrial" level (the level of average world temperature pertaining two hundred years ago).
Today, world average temperatures stand at about 0.75C above the pre-industrial, and many scientists and politicians agree that further increases have to be stopped at 2C if catastrophic impacts from the warming are to be avoided, ranging from widespread agricultural failure and worldwide sea level rise, to countless species extinctions and irreversible melting of the world's great ice sheets.
But the Hadley Centre's simulation indicates that even if global emissions of carbon dioxide, the main greenhouse gas causing the warming, were to be slashed at a very high rate the chances of holding the rise at the C threshold are no better than even. The scenario, prepared for Britain's Climate Change Committee, the body recommending the UK's future carbon "budgets", visualises world CO2 emissions peaking in 2015, and then falling at a top rate of 3 per cent a year, to reach emissions of 50 per cent below 1990 levels by 2050.
At the moment, global emissions are thought to be rising at nearly 3 per cent a year – so turning that into a 3 per cent annual cut would be a gigantic slashing of what the earth's factories and motor vehicles are pumping into the atmosphere. There is as yet nothing remotely like that on the table for potential agreement in Copenhagen, and if a deal of this ambition were to be done, it would be regarded as a triumph.
Yet even with that, the Hadley Centre research suggests, the chances of keeping the rise down to about 2C by 2100 would be only 50-50. Furthermore, the simulations suggest that there is a worst-case scenario – about a 10 per cent chance – of the rise by the end of the current century reaching, even with these drastic cuts, a level of 2.8C above the pre-industrial, which is well into disaster territory.
With any action that is slower than the scenario above, the likeliest outcome is a much higher eventual temperature – and in fact, the model indicates that each 10 years of delay in halting the rise in global emissions adds another 0.5C to the likeliest end-of-the-century figure. So if emissions do not peak and start to decline until 2025, we can expect a 2.6C rise by 2100, and if the decline only begins in 2035, the figure is likely to be 3.1C – even with 3 per cent annual cuts.
These new figures suggest quite unambiguously that the world is on course for calamity unless rapid action can be taken which is far more drastic than any politicians are so far contemplating – never mind the general public.
If action is sluggish or non-existent, the model suggests that climate change is likely to cause almost unthinkable damage to the world; under a "business-as-usual" scenario, with no action taken at all and emissions increasing by more than 100 per cent by 2050, the end-of-the-century rise in global average temperatures is likely to be 5.5C, with a worst-case outcome of 7.1C – which would make much of life on earth impossible. "Even with drastic cuts in emissions in the next 10 years, our results project that there will only be a 50 per cent chance of keeping global temperatures rises below 2C," said Dr Vicky Pope, the Met Office's Head of Climate Change Advice.
"This idealised emissions scenario is based on emissions peaking in 2015 and changing from an increase of 2-3 per cent per year to a decrease of 3 per cent per year. For every 10 years we delay this action another 0.5C will be added to the most likely temperature rise. If the world fails to make the required reductions, it will be faced with adapting not just to a 2C rise in temperature but to 4C or more by the end of the century."

How green is your energy - UK energy special
Cheap it may be. But is your electricity supplier clean or downright dirty? The argument over coal-fired power - often rated as the filthiest - is now white hot.
When we revealed a fortnight ago how to find the cheapest gas and electricity suppliers, E.ON emerged as one of our best buys. Readers then told us that, instead of saving money with E.ON, they wanted to switch away from the firm to protest against its involvement with new coal capacity at Kingsnorth, site of the Camp for Climate Action this summer.
Electricity has to come from somewhere - and most generation involves CO2 emissions or nuclear waste.
Only Good Energy is 100% sourced from renewables such as wind and waterpower. All companies have been set a government target of 9.1% of electricity from renewables by next March, rising to 15.4% by 2016.
Top of the coal burners is Scottish Power, where 55% of its generation comes from coal, substantially greater than its rivals. Not surprisingly, it also heads the carbon emission table.
EDF is the next biggest coal user at 47% followed by npower at 44% and E.ON at 42%. E.ON’s percentage is likely to rise should Kingsnorth get off the ground.
By contrast, British Gas (Centrica) takes just 18% of its needs from the fuel. It uses its own gas for electricity generation. But for those whose main worry is nuclear energy, Scottish Power’s supplies to its five million customers comes out well at only 1%.
Ecotricity, which figures prominently on green lists, mixes coal, nuclear, renewables and gas in almost equal amounts. The firm concedes it does not have a 100% green fuel mix although it does offer a 100% green supply for those who want it. “We are working towards more renewables. Our most popular tariff is made up of around 70% brown energy. Buying existing green energy, which is what most 100% tariffs contain, does nothing at all to reduce CO2 emissions or increase UK green energy capacity - you simply take something that already exists and have it for yourself.
“Robbing Peter to supply Paul is how we like to describe it. Most 100% green tariffs are a con, because they tell you you’ll reduce your carbon footprint etc, but don’t tell you someone else’s will go up as a direct result. Nothing really changes - it’s just a redistribution of existing green sources.”
Scottish Power says its high coal dependency is due to inheriting coal-fired stations - it owns Longannet station in Fife, one of the biggest in the UK. It is investigating “carbon capture” techniques. These cut down on emissions but are controversial on cost and energy grounds.
It says: “We will spend around £1bn on new renewable projects in the next two years including Europe’s biggest windfarm, Whitelee near Glasgow. Our renewable portfolio will be 10% of our capacity by 2010.”
But those who want pure green energy have to pay for it. A typical 3,300kilowatt electricity consumption costs £484 with Good Energy or £436 with Ecotricity New Energy Plus.
Scottish Power’s Green Energy H2O (it comes from hydropower) costs £354 (the same as its non-green supply) while the cheapest for non-green tariff (British Gas Click 5) costs £295.
Meanwhile Friends of the Earth says the best way to cut carbon is to turn off lights and power.
