Energy for Londoners: Mayor powers up £34m solar and energy efficiency plan. Mayor Sadiq Khan officially launched the latest phase of the Energy for Londoners initiative yesterday, detailing plans to invest £34m in a range of new services and programmes designed to boost energy efficiency and improve access to clean power across the capital. Khan announced that a new £2.5m package would help address fuel poverty across the capital, offering households up to £4,000 in Warmer Home grants to fund improvements such as new boilers, heating controls and insulation.
Green Investment Bank loan to finance almost 15,000 low energy LED streetlights with aim of halving Barking and Dagenham’s streetlighting bill, Barking and Dagenham council has secured a £6.8m loan from the Green Investment Bank (GIB) to help finance the roll-out of almost 15,000 energy efficient LED streetlights in the East London borough.
A £2.1m partnership between E.ON’s energy efficiency business and Edinburgh City Council is set to reduce on-site energy costs by 24% at nine public buildings, as part of the city’s overarching aim to reduce carbon emissions by more than 40% by 2020. The agreement means that E.ON’s energy efficiency business Matrix will guarantee savings from the implementation of energy conservation measures such as LED lighting and Combined Heat and Power (CHP) systems at buildings including seven schools, the Usher Hall and UNESCO World Heritage Site the City Chambers. The upgrade programme is designed to save more than £330,000 in energy costs and reduce carbon emissions by more than 1,500 tonnes per year. he project is a key initiative of Edinburgh City Council’s Sustainable Energy Action Plan that aims to reduce carbon emissions across the city by more than 40% by 2020. The Council’s 2020 objectives include more efficient energy consumption across all sectors by at least 12%, and renewable energy technologies contributing to at least 40% of energy consumed in the city. Last year, Edinburgh Council confirmed plans to install community-owned solar panels on 25 public buildings across the city. Edinburgh is not the only Scottish city with ambitions of becoming a world-leading centre for sustainable policy and innovation. Glasgow City Council partners with a number of businesses on diverse sustainable projects, which provide job creation and green capital growth. Glasgow recently ranked inside the global top 25 cities for environmental sustainability. Meanwhile, Aberdeen has become the first city in Europe to offer hydrogen powered cars for public use on a pay-as-you-go basis, as part of the City Council’s next step in expanding hydrogen infrastructure in the city. Plans to drill a deep geothermal well beneath the city of Aberdeen could deliver heating to thousands of nearby homes and an exhibition centre.
A nationwide shift to LED lightbulbs could slash the risk of a winter blackout, according to new research from Greenpeace. The research, carried out by energy analyst Chris Goodall, found a switch to the energy efficient LEDs in homes would reduce peak electricity demand in the winter by five per cent, or 2.7GW. The study also calculates the use of LEDs in office and other commercial building could save around 4.5GW, around nine per cent of peak demand, while LED street lighting would save a further 0.5 GW. While lighting might not seem an area of high energy demand, it is responsible for nearly a third of total winter peak electricity demand, according to the research. It calculates that a complete switch to LEDs would likely halve power use from lighting. Greenpeace said the research shows a business and government drive to promote a switch to LEDs could see a reduction in the UK’s electricity demand equivalent to over two Hinkley Point nuclear plants’ worth of electricity. Greenpeace estimates it would currently cost around £1.7bn to switch the most used bulbs in all UK homes to energy-efficient LED lighting, adding that the transition could be completed “relatively quickly”. The payback period for switching the most used lighting typical domestic house to LED is two to three years at current prices, with the estimated £62 cost of replacing 21 bulbs in living areas likely to cut annual electricity bills by at least £24, Greenpeace said. However, the new analysis also shows that in addition to helping cut domestic energy bills a national switch to LEDs would help save at least £65m a year on capacity market payments, reducing the subsidies the government pays for back up power capacity.
A new NHS sustainability report reveals the health service could save in excess of £26m a year by increasing adoption of combined heat and power (CHP) technology. The Securing Heathy Returns Report, which analyses the financial value of key sustainability measures in the NHS, states that CHP provides the biggest energy-saving opportunity – amounting to £26.4m a year. That’s enough to fund the salaries of more than 1,200 newly-qualified registered nurses. The report, published by the Sustainable Development Unit (SDU) for NHS England and Public Health England, analyses 35 proven measures that it says could achieve a total of £400m of cost savings and reduce carbon emissions by a million tonnes every year by 2020. These interventions were selected because they are supported by robust data and evidence to enable analysis and scaling. Of the 18 energy-saving measures covered in the report, CHP provides the highest annual potential cost savings (£26.4m), followed by staff energy awareness and behaviour change (£21.5m); high-efficiency lighting (£7.2m); and reducing temperature set points by one degree Celsius (£6.2m).
The NHS has saved more than £5m through taking a variety of sustainable measures, according to a new report released today from the NHS Sustainability Day campaign. The report rounds up submissions of financial and carbon savings from hospitals and NHS Trusts across England, achieved through a range of initiatives from energy efficiency measures through to waste management and the uptake of low carbon vehicles.
LED light bulbs are cheap and energy efficient, writes Chris Goodall. A crash programme to replace all the lights in the UK with LEDs would cut electricity bills, reduce carbon emissions and other pollution from coal and diesel generation, and reduce the risk of blackouts. At the peak at about 5.30 on a December evening lighting uses about 15GW (gigawatts / billion watts) out of total UK demand of approximately 52GW. This is an almost unbelievable 29% of our need for electricity, met at the precise moment that future blackouts are most likely. And there’s a simple way to cut that peak electricity demand – making our lighting more efficient by a mass switch to high efficiency LED lightbulbs. If all lights across the country were switched to LEDs my calculations (carried out under a project for Greenpeace UK) suggest that the need for electricity to provide improved lighting would fall by about 8GW, a saving of about 15% of all power consumption. As part of my work for Greenpeace, I located 100 case histories of switches from other types of lights to LEDs in industry, commerce and public sector. On average, replacing less efficient bulbs saved two thirds of the electricity bill. These studies were usually written up by companies with an interest in selling more LED bulbs, but show a very consistent pattern across factories, shops, schools, sports clubs and offices. In most places, lighting quality was improved substantially. In some locations electricity costs were reduced because LEDs produce less waste heat and therefore cut the need for air conditioning in places such as hotels and large office buildings. Even a much more restricted national campaign that just focused on domestic houses would have a dramatic impact. If we switched the lights in the parts of the house that are in use in early evening – essentially the kitchen and living areas – we would reduce home demand by more than 50%. Importantly, these rooms are the places where we now often use halogen downlighter bulbs, the most inefficient lights currently on the market. A standard halogen GU10 bulb uses 50W of power. The LED equivalent does the same job with just 5W.
Green Investment Bank’s latest LED street lighting deal highlights how green loans should become a ‘no-brainer’ for councils and businesses. The GIB’s latest announcement it is to provide a Green Loan to Stirling Council to fund the installation of 12,000 LED lamps and 4,000 lampposts as part of a major street lighting upgrade is the third of its type, and certainly won’t be its last. The benefits from the deal are compelling. Stirling Council will borrow £9.87m over four financial years to fund the upgrades. Repayments are then spread over a lengthy period of up to 30 years at a relatively low fixed interest rate, which means the energy bill savings exceed the repayments. Consequently, the council can expect to save £31m over 30 years while also cutting carbon emissions by 63 per cent. The soon to be privatised GIB, meanwhile, gets a stable and extremely low risk return from a public sector customer. There are currently seven million streetlights in the UK, fewer than one million of which use proven LED technology. Councils face a £300m a year lighting bill, an overhead so high some cash-strapped authorities have taken to turning lights off to save money. In this context, green finance packages that deliver all but guaranteed energy bill and carbon savings are such a no-brainer local authorities really should be deploying them faster than you can say ‘controversial council tax hike’. What is now needed, as it was eight years ago, is for the banking sector to flick the switch and make green finance a truly mainstream concern.
Danish lighting company Scotia unveils new range of solar-powered streetlights that promise to turn local authorities into ‘energy powerhouses’ London may take a lead in zero-emissions street lighting later this year if plans go ahead to install the first wave of a pioneering streetlight that illuminates streets and feeds energy back into the grid using only solar power. The Monopole street light, developed by Danish solar lighting firm Scotia, collects solar energy during daylight hours and stores it in a battery for use after sundown. Not only do the lights generate enough energy to power themselves, they can also feed energy back into the local grid to turn local authorities into “energy powerhouses”, according to Scotia’s founder Steven Scott. According to Scotia, if all of the UK’s seven million streetlights were switched to Monopoles, it would save more than £300m in electricity costs and generate more than 4TWh of clean power per year. Some 40 per cent of this would feed back into the grid, saving more than two million tonnes of CO2 every year, it added.
Most farms have outlying barns and sheds where there’s no mains power. That’s no problem in the daytime, but no fun if you have to rely on a torch after dark. However, Berkshire firm Bright Spark Solar reckons it has the answer with its latest 44-LED solar-powered floodlight. The lithium-ion battery is fully charged after nine hours of bright sunlight, it says, which then gives five nights of light from the low-wattage LED floodlight.
