Energy efficient appliances

London, 24th November 2008

Everyone is aware that household white goods such as washing machines and fridges are being made more energy efficient. The European Energy Label, with it’s ‘A’ to ‘G’ rating and coloured arrows, is now familiar on washing machines, refrigeration appliances, tumble driers and dishwashers. It also applies to ovens and air conditioning units, as well as light bulbs.

This labelling system is simple to understand and allows a quick comparison between appliances, and for white goods anyone wanting to be energy efficient will buy an appliance as efficient as possible when they are replacing an old one. There are however a couple of issues with the system.

First, it is very hard to work out when it is better or more cost effective to replace an old but working model with a new, more efficient model, and what the payback period might be. There are very few tools to help with this, although future energy management products will help.

Secondly, the rating is not about an absolute level of energy used, but about how efficient the device is for what it is. A large ‘A’ rated double door fridge freezer will almost certainly use more energy than a worse rated, under the counter sized, model. The purchasing decision should therefore be not just to buy an efficient model but to buy a sufficient model; one that meets your needs and is not more than required.

For other goods, the decision is harder as the information is less easy to come by; probably the biggest area is home entertainment equipment, especially televisions. Again though, when purchasing decisions about which appliances to buy in order to be energy efficient people should look at the actual energy used. For most people selecting a television, the choice would be size first, and then perhaps check the power rating for models of that size. However, smaller models are almost certain to have a lower use of energy, and the decision should be a trade off between desire and energy use.

A final category of appliances is of course the items that have manual equivalents, which use no energy. An electric toothbrush uses more energy than a manual one. A food processor uses more energy than doing it by hand. While no one is advocating that we go without labour saving devices, the proliferation in a modern home can be enormous, with a corresponding consumption of electricity.

In conclusion, the best way to be energy efficient is to buy appliances with the smallest energy consumption for your needs, which may be zero, but to bear in mind the energy benefits of not replacing an existing appliance.

Onzo Goes Into Parliament

London, 24th November 2008

Onzo has just been elected as a corporate member of the Parliamentary Group for Energy Studies, the pre-eminent cross party energy group, which forms a bridge between MPs, Peers and members of the European parliament. and the energy sector. It currently has around 200 parliamentary members and its existing corporate members include Scottish and Southern Energy, Centrica, EDF, National Grid and British Energy. Membership is usually limited to major companies such as these and the invitation to Onzo to join is a recognition both of the importance of home energy management systems and our role in their design and of the part we are playing in contributing to public policy debates on energy issues. We are the only business active in our sphere to be a member.

The Group meets monthly in the Palace of Westminster. Recent speakers have included: the Chancellor of the Exchequer; Macolm Wicks, until recently Energy Minister; Charles Hendry, the Conservative energy spokesman; Alistair Buchanan, Chief Executive of the energy regulator, Ofgem; and Ian Marchant of SSE (who was talking about smart meters).

Membership of the PGES will give Onzo an excellent opportunity to network at the highest level and to continue to operate in the Premier League of the energy world.

The Reality of Fuel Poverty

London, 24th November 2008

A few years ago the Government claimed to be winning the war on fuel poverty: ministers boasted that four million households had been lifted out of fuel poverty between 1996 and 2004.  All of a sudden the picture is much less bright.  Between 2005 and 2006 the number of fuel poor rose by around a million, to stand at roughly 3.5 million (around 14 per cent of all households), and some estimate that the figure will double, to seven million, by the end of 2008.

When the original fuel poverty strategy document was published in 2001 fuel prices were at their lowest in real terms since 1974.  That paper said: “The main cause of fuel poverty in the UK is a combination of poor energy efficiency in homes and low incomes”.  It went on to suggest that a reasonable range of price movements between 1999 and 2010 was +15 per cent to -10 per cent in real terms for domestic gas prices and +5 per cent to -2 per cent for domestic electricity prices.  This has not exactly been justified by events.  In August 2008 alone domestic electricity prices increased by around 20 per cent and gas prices by around 30 per cent, following 15 per cent increases in January, and National Grid recently warned that a further round of price rises is inevitable before the end of the year.   But the sudden and steep escalation in fuel prices should not be allowed to distract us from the underlying issues that drive fuel poverty.  These remain the same – poor efficiency and inadequate incomes.  They affect us all to varying degrees; and the government has failed to tackle them adequately.

Elements in the Labour and Liberal Democrat parties and the trade unions still hanker after a windfall tax on energy companies, but that is not the answer.  At the best of times windfall taxes alienate business, which likes certainty in earnings and does not want profits periodically diverted to the Treasury when it is short of cash – in the present global financial crisis such an added burden on business would be insanity.  We need energy companies to invest in the UK, in generation, distribution and metering; any diversion of funds will adversely affect capital expenditure plans at a time when the “cushion” between energy supply and demand is dangerously small. The legal process to impose a windfall tax would be drawn out and even if one were eventually imposed it is doubtful it would do the fuel poor any good.  Hypothecation, the devotion of tax revenue for specific purposes, although it happens from time to time, is not generally the way our tax system works.

In the debate about fuel poverty, pre-payment meters are usually demonised, but they are not the root of all evil they are often painted.  In fact only a quarter of pre-payment meter customers are fuel poor. Such meters are used by many people in the same way as pay-as-you-go mobile phone contracts – Energywatch has reported that 66% of all customers who choose pre-payment meters do so to control their energy spending, and Ofgem research has found that the majority are happy with this method of payment.  The number of pre-payment meters has also risen in recent years as a preferable alternative to disconnection and as one way to repay accrued debt.

Pre-payment meters are costly to install and more expensive to administer than other methods of payment and some energy companies pass these costs on to the customer.  It is not necessarily right to criticise them for doing so, any more than it would be to condemn them for sharing with their customers the benefits of cheaper payment processing methods.  However, it is necessary to ensure that those methods – direct debits and online billing – are available to all, and that they are explained to people in such a way that their concerns about them are allayed, as Ofgem is demanding.

It is good that the government has secured a commitment from the energy companies to spend £910m over three years on energy efficiency.  UK housing stock is chronically thermally inefficient, probably because we have a temperate climate with no great extremes of heat or cold and because energy prices were low while North Sea oil and gas reserves remained high.  But as large a sum as close to a billion pound sounds, it will not go far.  It will probably improve the insulation of somewhere between 100,000 and 200,000 homes in each of the three years – a drop in the ocean when there are around 22.5 million homes in the UK.

According to the definition of fuel poverty enshrined in the Warm Homes and Energy Conservation Act 2000: “a person is to be regarded as living ‘in fuel poverty’ if he is a member of a household living on a lower income in a home which cannot be kept warm at reasonable cost.”  This definition conflates several issues: 1. energy prices; 2. household income; 3. energy efficiency; and 4. vulnerability to low temperatures.  Let us look at each in turn.

1.    The key to containing energy prices is the development of a long-term generation strategy because price is a function of supply and demand.  This strategy needs to set out what proportion of energy should be generated by nuclear, oil and gas, coal (preferably with carbon capture and storage), renewables, local schemes, and micro-generation.  It must take account of security of supply and the need to reduce our reliance on imports from politically unstable regions and susceptibility to economic blackmail.

2.    Household incomes are dictated by salaries and wages, pensions, tax credits, disability allowances and other benefits. Vulnerable people should be able to afford the necessities of life, and payments should keep pace with necessities.  Benefits such as winter fuel payments are directed to the elderly but wrongly exclude other deserving categories such as the very young and those will breathing difficulties.

3.    Energy efficiency depends on the energy performance of dwellings, the efficiency of a dwelling’s heating technology and individual behaviour.   Heating space and water accounts for 60 to 80 per cent of domestic energy use. Around 18 million homes are owner-occupied; three million are privately rented; two million have social landlords – mostly housing associations; and 2.5 million are under local authority control.  Rented dwellings must have Energy Performance Certificates, but as landlords have no obligation to act on them the stipulation is pointless.  Unfortunately, the heating technologies that cost least to install are often those which cost most to run.  There therefore needs to be a requirement on landlords to improve the energy performance of the accommodation they provide. For privately owned and occupied accommodation, Energy Performance Certificates are more useful, although as they are they are now subsumed in the ineffectual and disliked Home Information Packs there is a danger they will become unpopular by association.  Something more needs to be done to reduce the main barriers to improving housing stock: the high capital cost and the extended payback period, and the poorest must be given financial assistance to encourage them.

Above all the other issues stands individual behaviour – seldom mentioned in relation to fuel poverty. It encompasses both the choice of appliances and their use.  We set thermostats and on/off settings for central heating and hot water and just as the fuel crisis of the late 1970s taught us all about mpg, so now we need to learn about kWh.  We need to know how much energy appliances consume.  We need to know how much we could save by taking certain actions.  We need prompts for when to use and when not to use energy.  We need to know how much we use compared with other people.  We need to know how we are performing against a target.  At the beginning of the road to ch
anging behaviour is accurate, timely and understandable information which can readily be acted upon, which could range from energy efficiency labelling on appliances to indicators on energy displays, from printed information to websites.

Fuel Poverty is an archetypal challenge to “joined-up government”.  The establishment of the Department for Energy and Climate Change will go some way to achieve this as it will presumably take over the responsibility for fuel poverty which was previously fragmented over a number of departments.  We have yet to see how this will operate in practice, however, or how other departments with an interest in the area (especially the Treasury) will work with the DECC.  Moreover, household incomes are still “owned” by the Department for Work and Pensions, while issues relating to dwellings are dealt with by the Communities and Local Government Department. so true co-ordination remains incomplete. Equally disappointingly, the important potential of the internet as a channel of information on energy usage seems lost in the Department for Culture, Media and Sport because it is assumed to be primarily a channel for entertainment.   In fact it is fast becoming an essential utility.

What is irrefutable is that money to tackle fuel poverty should be directed at improving the least energy efficient dwellings and those with outdated heating technology, and towards helping people on the lowest incomes and those most vulnerable to low temperatures – the youngest, the eldest, those with impaired mobility, and those with conditions that affect breathing. That means handouts until the infrastructural improvements can be made, and a much more vigorous programme to better the energy efficiency of the housing stock.

In the meantime, many may feel the only answer is to turn their heating down or off.  If they do the government may be held responsible through its failure to address the underlying issues in time.  A short term “sticking plaster” is inevitable, but this does not make permanent solutions any the less pressing.

Onzo’s Radio Response

London, 13th November 2008

On Thursday 12th November the Today programme on Radio 4 had a lengthy piece on the looming gap between energy supply and demand. It reported the findings of a questionnaire it sent to 31 “experts”, who almost all expressed frustration about the government’s “dithering” although they mostly discounted suggestions that the lights were about to go out in the immediate future. They deplored our dependence on the international price of gas, and “called for new ways of doing things”.

The results of this survey can be found here.

The following is Onzo’s comment on the experts’ conclusions:

We agree there is no need to be alarmist; it is unlikely the lights are going to go out in the near future and unhelpful to suggest they will. Nevertheless, constraints on supply, and rising demand as the population increases, clearly pose a serious problem and there are no grounds for complacency. There is undoubtedly a need for new ways of thinking, and for far greater diversity of supply including renewables, nuclear and carbon capture. 80 per cent of our gas will come from foreign sources by 2020 and even without concern for the environment we cannot go on as we are.

We must not, however, lose sight of concern for the environment. Tackling climate change is just as much an economic as a social imperative and we agree with the vast majority of the respondents who stated that the government “must not relax its commitment to carbon cuts in order to maximize the supply of cheap energy”.

Of course there is need for massive investment in energy infrastructure, which has been neglected by successive governments for more than a quarter of a century as we basked in the false sense of security engendered by North Sea oil and gas. As almost all the respondents agreed, revenue from the auction of carbon gas emission trading permits should be used for this specific purpose, rather than being swallowed up by the Treasury, even if it is then used for the purposes of general economic stimulation. Transmission systems, gas storage, carbon capture; all need a large-scale injection of capital.

As much emphasis must be placed on reducing demand as on increasing supply. This becomes more imperative if calls for the “de-carbonisation” of the economy, as advocated by Lord Turner of Ecchinswell and the government’s climate change committee, are heeded. The electrification of many processes, both in the home and in industry, that have up to now run on gas will inevitably increase power generation.

Energy efficiency is vital to demand reduction. This is true of industry and commerce but the scope here is somewhat limited and it is perhaps in the home that the greatest scope for saving can be found. Domestic energy use continues to grow and more than 30 per cent of carbon gas emissions come from the home.

The importance of domestic energy saving has been recognized by the government, possibly belatedly, and the energy suppliers have agreed to contribute £910m over three years to this purpose, largely through promoting home insulation. This is only a drop the ocean, however. It will probably only improve the insulation of somewhere between 100,000 and 200,000 homes in each of the three years – there are around 22.5 million homes in the UK.

A more radical way of financing home energy efficiency improvement is needed; one that gets round the reluctance of home owners to spend money on measures which, they perceive, will not return their investment for years. Onzo advocates getting round this problem by adopting a variant of schemes being tried in various places in the United States, most notably Boulder in Colorado and Berkeley in California. We have proposed that local authorities should adopt the same model to fund energy efficiency improvements through loans, collecting the repayments through the Council Tax. The money could be raised either through traditional borrowing or by issuing bonds

At a stroke this idea solves two main problems. There is no need for individuals to raise the money to make their homes more energy efficient in full, and the cost and benefits remain with the property so that whoever lives in it pays off the loan and receives the benefit.

The government recently announced plans for the general roll-out of smart meters by 2020 amid much comment about how potent a weapon this is in the battle to reduce energy consumption. The survey, however, revealed overwhelming scepticism over how much impact they will have and we share these reservations. Smart meters do have their uses; they will provide more accurate billing and eliminate the problem of estimated bills that are so frustrating to the customer. If and when they facilitate feed-in tariffs for small-scale micro-generation they will indeed be contributing to redressing the supply-demand balance.

At the present state of technology, however, they will do little or nothing to stimulate thorough-going behaviour change. This is the key to reducing domestic energy demand if we are not to experience state intervention on a scale unseen since wartime rationing. By contrast energy displays, informative in themselves and linked to a sophisticated web service that provide a broad range of personalized information, will provide the knowledge to stimulate behaviour change on a large scale.

We do not see displays, and the systems that support them, as alternatives to smart meters, but as complements to them. As the potential of information and communications technology to benefit both society and citizen in ways which are only now beginning to become clear, emerges, Onzo expects this combination of tools to provide a potent Twenty First Century solution to one of the gravest issues of the age.

Parliament Powers Ahead on Carbon Emissions and Smart Meters

London, 7th November 2008

Apart from the slight matter of a little election in America, the past week has seen two significant parliamentary events here at home. The first was the completion of the Climate Change Bill’s progress through the House of Commons. This measure enshrines in law the government’s commitment to reduce carbon gas emissions by 80 per cent over the next 40 years. It only passed after ministers bowed to backbench pressure and agreed to include emissions from civil aviation and shipping, and as it is calculated these two sectors will account for six per cent of all carbon output by 2050 it is hard to see how the targets can be reached without their inclusion.

Meanwhile, in the House of Lords, the Minister of State at the new Department for Energy and Climate Change, Lord Hunt of Kings Heath, declared a commitment to the general roll-out of smart meters by 2020, seemingly in response to a Conservative initiative. Initially there will be a two-year period during which “the issues are resolved and full details designed” and there is some concern in the industry that this may not allow enough time to resolve the many problems that still stand in the way of developing successful smart metering systems. There is a danger that if the preparation period is set in stone, a gadarene rush to install immature technology may result. Moreover, it has not yet been decided who exactly will pay for the whole exercise and how the competitive tendering process for smart metering will work.

On a more positive note, the roll-out is to be tied to the development of “feed-in tariffs” to allow surplus energy from small sale domestic microgeneration to be fed into the grid. Here again the Tories seem to be showing more enthusiasm for the idea than the government. One Labour peer argued that “putting a windmill on the side of your house would probably mean that your house flew away rather than that you generated electricity”.

Both debate on the Bill and commentary in the press revealed a degree of misunderstanding of the purpose and capability of smart meters. We have sent a note to some of the leading participants in the debate pointing out that smart meters do not of themselves provide customers with the information which would enable them to understand and manage their energy use. By contrast, we explained, home energy displays, complementing smart meters, would serve this purpose.
