Home Energy Management

  1. 1. Home Energy Management Fast, affordable … and essential Pilgrim Beart, AlertMe.com
  2. 2. “ Save Energy Now” <ul><li>90% of consumers are concerned about their energy bills </li></ul><ul><li>and want to save money (and energy) now* </li></ul><ul><li>But consumers lack the necessary information </li></ul><ul><li>and lack the ability to easily control consumption. </li></ul>Governments worldwide are driving ‘energy saving’ because of both Energy Security and Climate Change Personal UK energy consumption † * AlertMe survey of 1000 broadband users, Sep 2008 † Sustainable Energy without the Hot Air
  3. 3. UK generating capacity EDF
  4. 4. UK 3,300 kWh Electricity Natural Gas 20,500 kWh USWITCH JUNE 2008
  5. 5. CALIFORNIA 49 therms/household/month =588 per year = 17,000 kWh Electricity Natural Gas 5914 kWh 17000 kWh http://www.pge.com/about/environment/calculator/assumptions.shtml http://www.californiaenergyefficiency.com/docs/EEStrategicPlan.pdf
  6. 6. UK Domestic energy consumption <ul><li>Average household: </li></ul><ul><ul><li>Disposable income £14,520 </li></ul></ul><ul><ul><li>Domestic energy bill £1,213 (8.3%) </li></ul></ul><ul><li> (U-switch press releases, 6 June 2008, 26 Aug 2008) </li></ul><ul><ul><li>10% of electricity wasted on standby (NAO, 2008) </li></ul></ul>
  7. 7. So why don’t consumers do something about it? Fear of complexity? Fear of unknown? Disruption? Laziness? Ugliness? ROI too poor or slow? Cost up-front?
  8. 8. Obstacles <ul><li>E.g. condensing boiler retrofit </li></ul><ul><li>Vaillant: </li></ul><ul><li>“ Switching your boiler could save you over £240* a year on heating bills because our high efficiency systems use 35% less energy” </li></ul><ul><ul><li>But installed cost ~£2200* </li></ul></ul><ul><ul><li>ROI ~10 years </li></ul></ul><ul><ul><li>Disruptive </li></ul></ul>* Average UK (boiler+install) from whatprice.co.uk Nov 2008
  9. 9. Energy-saving : saturated? BERR 95% 74% Hot water tank insulation 84% 10% Double glazing 95% 51% Loft insulation 2005 1976   Households with this measure Insulation measure
  10. 11. Managing Demand
  11. 12. Many different solutions <ul><li>And we need many! </li></ul><ul><li>Even the slow, expensive, hard ones </li></ul><ul><ul><li>(perhaps especially those) </li></ul></ul><ul><li>but don’t forget the quick, cheap, easy ones! </li></ul>
  12. 13. Smart Meters <ul><li>Europe </li></ul><ul><li>Italy already rolled-out AMR – too early </li></ul><ul><li>Sweden by 2009 </li></ul><ul><ul><li>Gothenberg 300k home “ZigBee city” </li></ul></ul><ul><li>UK by 2020 </li></ul><ul><li>USA </li></ul><ul><li>California (regulated), 3.3m meters by 2011 (pop 36m) </li></ul><ul><li>Texas (deregulated), 7m meters by 2019 (pop 23m) </li></ul><ul><li>then… </li></ul><ul><li>Demand management (2 years after meters?) </li></ul><ul><li>Smart-Energy-aware Appliances (7 years after meters?) </li></ul>
  13. 14. Energy management - Closing the loop BEHAVIOUR AUTOMATIC MEASURE CHANGE
  14. 15. Academic Studies <ul><li>Consumer Behavioural Effects of making consumption visible: </li></ul><ul><li>Savings of 5-15% </li></ul><ul><li>Best long-term effects from Billing or other periodic feedback </li></ul><ul><li>Processed feedback best for demonstrating effects of changes to heating, efficiency measures or high-consuming appliances. </li></ul><ul><li>Indirect feedback best for showing heating load. </li></ul><ul><li>Historic feedback (comparing with previous recorded periods of consumption) more effective than comparative or normative (comparing with other households, or with a target figure). </li></ul>“ The effectiveness of feedback on energy consumption - a review for DEFRA of the literature on metering, billing and direct displays” by Sarah Darby of the Oxford Environmental Change Institute, April 2006
  15. 16. Evidence <ul><li>UK energy trials show that consumer pull is vital for adoption </li></ul><ul><li>90% of consumers are concerned about their energy bills and want to save money (and energy) now </li></ul><ul><li>67% would pay £10/month for an energy-saving service which claimed to save on average £31/month </li></ul><ul><li>Focus groups have shown the need to remove the need for an “energy policeman” and engage the whole household </li></ul>
  16. 17. Solutions Set heating and cooling automatically, taking into account multiple temperature points, presence information, weather, day of week, house specific heating lag and more. Read your meter anywhere (TV, phone, web…). Real-time and historical. In £ not kWh. Alternative tariffs. Accurately measure energy usage at outlet and control it locally, remotely or automatically. Installs in seconds.
  17. 19. Smart Energy in 2009 (not 2029!) Smart Meter Smart Meter Gateway Backhaul (wired) Backhaul (wireless) Back End Displays Phone SMS TV Web Ambient API Presence Safety Load Control (inc. EV) Smart Appliances Whole-house Temps Heating Control Value-Added Services Retrofit Utilities and other service providers HAN AlertMe launched in 1Q 2008 AlertMe to launch in 1Q 2009 Smart Meter Smart Plugs
  18. 20. Removing obstacles Keep it simple Fear of complexity? Market through familiar channels Fear of unknown? Easy install Disruption? Create pull with an attractive consumer proposition Laziness? Ugliness? ROI instant, if sold as service ROI too poor or slow? £0 with rebate checks/CERT Cost up-front?
