Energy Saving: The UK Perspective and Addressing Issues of Fuel Poverty Keith Tovey Energy Science Director CRed Project Н.К.Тови М.А., д-р технических наук Факультет экологических исследований Университета Восточной Англии
Energy Saving: The UK Perspective• The Background to Energy Conservation – Why is it important?• Tariff Structure and issues of Fuel Poverty• Perception of Energy Conservation in the UK?• How is Energy Conservation promoted in the UK?• Conclusions
Energy Saving: Why is it important?• The UK has been self sufficient in energy• Under present trends the UK will be a substantive importer of natural gas and oil by 2020• It makes sense to reduce energy demand and still remain competitive economically.• Reducing energy demand will also see a reduction in carbon dioxide - the main contributor to Global Warming• The Government has set targets and provided mechanisms to provide grants for individuals and industry.• However, more could be done.
The Background to Energy Conservation• In UK each person is consuming energy at a rate of 5.1 kW• In USA it is 10.6 kW 1/20th or World’s Population consumes 25% of all energy• In Europe it is 5.7 kW• In Russia it is also 5.7 kW• Globally it is around 2 kW• ENERGY Consumption > Carbon Dioxide > Global Warming

Energy Tariffs: The UK PerspectiveTraditionally tariffs in UK composed of two parts: A standing charge irrespective of level of consumption• A unit rateThis adversely affected low consumers.Since Deregulation the majority of tariffs now have a break pointtariff• No standing charge:• First N units at a relatively high rate• Remaining units at lower rateHas less effect on low consumers.Some companies have tariffs including both a standing charge and abreak point tariff

The Role of the Regulator• OFGEM controls the prices charged by National Grid (Transco) and the Distribution Companies• These are natural monopolies.• Transmission and distribution make up around 25-30 per cent of the average domestic bill.BUT• OFGEM also has a duty to ensure the companies can finance investment needed to rewire Britain.• Rewiring is necessary with increased use of Renewables.
Consumer ProtectionEnergywatch: set up by the Utilities Act (2000). • Funded by Department of Trade and Industry • Funding comes from the licence fee paid by all energy companies • It looks after consumers interests and deals with complaints • Energywatch is accountable to the DTI. • Energywatch is separate from OFGEM. • Two organisations work closely together. • Relationship with OFGEM is set out in a Memorandum of Understanding.
Consumer Protection Energywatch:Some key projects currently underway by Energywatch:• Dealing with Rogue Traders who try to get people to switch suppliers• Dealing with late and inaccurate bills• In 2002/2003 Energywatch had • 45,546 account, billing and other complaints (up from 37,075)* • 34,027 transfer complaints (up from 30,743)* • 12,960 direct selling complaints (up from 6,991)*
Metering•Specialist Metering Companies have entered market since 1998.•Siemens Energy Services is now the largest independent supplierof metering services.•It reads gas and electricity meters throughout the UK•Processes customer data and handles the payment of bills.•Siemens covers nearly 8 million households (around one-third)•It provides a metering service for •British Gas, •Powergen, • npower, •Scottish Power, • Scottish & Southern Energy.
Energy Tariffs: The Question of Fuel Poverty• Privatisation• Introduction of Pool• Deregulation• NETA / BETTA• Were designed to reduce charges to consumers and domestic consumers in particular• Would address the Government aim of reducing number of people classified as “Fuel Poor”• Deregulation had the greatest effect• Fuel prices have risen substantially in recent 2 years in response to rises in Whole sale Prices• In Real Terms – prices are now approximately back to pre – Deregulation Prices.• Government provide all pensioners with £200 heating allowance each year.

Energy Saving: The UK Perspective• The Background to Energy Conservation• Tariff Structure and issues of Fuel Poverty• Perception of Energy Conservation in the UK? • The Domestic Sector • An example from a large business• How is Energy Conservation promoted in the UK?• Conclusions
The Background to Energy ConservationHow much Carbon Dioxide is each person emitting as aresult of the energy they use?In UK 9 tonnes per annum.What does 9 tonnes look like? Equivalent of 5 Hot Air Balloons! To combat Global Warming we must reduce CO2 by 60% i.e. to 2 Hot Air Balloons How far does one have to drive to emit the same amount of CO2 as heating an old persons room for 1 hour? 3.2 km
Energy Saving: Awareness / Education / Advice• Understandable LanguageA mobile phone charger left on ------ up to 25 kg CO2 a yearStandby on television > 60 kg per yearFilling up with petrol (~£30 for a full tank) --------- 90 kg of CO2 (5% of a balloon)A tumble dryer uses four times as muchenergy as the equivalent washing machine - use the dryer sparinglyBoiling an extra cup full of water causes theemission of 25 cupfuls of carbon dioxide.
Energy Saving: Perception of Energy Conservation in the UK? Domestic Consumers• some see Energy Conservation as a way to save money – less interested when they learn it may take many years to pay back• others see Energy Conservation as a moral and environmental issue and will strive to incorporate energy saving at an early stage• many over-estimate the size of their energy bills• several people see themselves as already being energy efficient. – PowerGen Energy Monitor (October 2004)• many are influenced by other factors – e.g. double glazing rather than cavity insulation!• Many are unaware of what grants are available
