Overview of Energy Efficiency & Renewable Energy (Draft version)

1. CANMET- EDRL Natural Resources Canada Ressources naturelles Canada Overview ofEnergy Efficiency & Renewable Energy (Draft version) Prepared by Natural Resources Canada in association with Indian and Northern Affairs Canada

2. Purpose • To provide information on Energy Efficiency (EE) and Renewable Energy (RE) measures and technologies • To illustrate how EE and RE can serve community energy needs • To increase awareness about EE & RE technologies • how EE and RE save money • introduction of EE and RE into decision process • implementation considerations

3. Reasons • Environmental • climate change and local pollution • Economic • life-cycle costs • depletion of fossil fuels • reduced drain of $$$ from community • Social • employment generation • energy independence • security through diversification of energy supply • contribution to sustainable development objectives • less $ out from community

4. Energy Demand in Canada Industry Buildings Transportation Contents • Renewable Energy • electricity generation • space heating and cooling • Information Sources • Overview • Energy Efficiency • housing and buildings • communities

5. How and Where Energy is used • Buildings(lights, appliances, heating, cooling) • Communities(waste heat, district heating) • Off-Grid(fishing camps, water-pumpers, communications) • Industry • Transportation HouseEnergy Use Light/appliances Water Heat Space Heat

6. Definitions • Renewable Energy: using non-depleting energy resources to do the same task • Energy Efficiency: using less energy resources to do the same task Energy Expenses in a Remote Community ResidentialSpace Heating Other Power Generation Non Residential Space Heating

7. Introduction • Common characteristics of EE and RE: • low to high initial costs • low to no operating costs • environmentally clean • no resource depletion • cost effective in many cases • reliability and longevity

8. Deciding on EE / RE • Relevant factors: • local environmental considerations • economics • keeping money in community • local employment benefits • desire for energy independence • aesthetics • operational simplicity

9. Cost of an Energy System • Cost effectiveness = doing thingsRIGHTfrom the start • in new construction • in renovations • in other opportunities to upgrade • replacing windows, • light bulbs, etc.

10. Concept of life-cycle cost

11. Cost of an Energy System • Cost of purchase total cost of system • Total cost ofenergy system(life-cycle cost)  purchase cost + installation cost + annual fuel costs + operation expenses + maintenance & repair costs + major overhaul costs + replacement at end of life + decommissioning costs

12. EE in Housing & Buildings Reduce energy consumption for the same level of comfort

13. EE in Housing & Buildings • Introduction • 55 % of energy demand is for heating in remote communities • all communities and buildings can benefit • schools often largest energy user • applies to new and existing buildings • must respect air tightness concerns

14. EE in Housing & Buildings • Factors affecting EE application • climate • building design, construction and siting • occupancy • condition of buildings • sources of energy and energy using equipment

15. EE in Housing & Buildings • Benefits of EE • occupant comfort, health and safety • reduced operating cost and fuel requirements • increased building longevity

16. EE in Housing & Buildings • Energy auditing • analyzing energy demand • identifying improvements

17. Energy Efficiency inExisting Housing & Buildings • Low cost measures: • lower hot water tank temperature • add insulation to water heater • install hot water flow restrictors • turn off lights • caulk/seal leaks • set-back thermostat • service/clean heating system

18. Energy Efficiency inExisting Housing & Buildings • Medium cost measures : • add insulation to basement, attic, walls, floor • upgrade windows and doors • add air-to-air • heat exchanger • install high • efficiency lights

19. Energy Efficiency inExisting Housing & Buildings • High cost measures: • New heating equipment • Add vapour and air barriers to whole building • Install high efficiency heating equipment

20. Energy Efficiency in New Housing & Buildings • Conventional measures • use good house/building orientation • increase insulation levels • use modern air sealing and ventilation techniques

21. Energy Efficiency in New Housing & Buildings • R2000 / C2000 • exceeds conventional standards • in widespread use • 40 % energy saving • quality, quiet and comfort benefits • builder training and qualification • payback - less than 7 years

22. Energy Efficiency in New Housing & Buildings • Advanced housing • exceeds R2000 standards • demonstration units only • common features • emerging technologies • Green housing • applies in new/retrofit housing • water saving devices • Ecologo products • waste treatment systems • recycling

23. Energy Efficiency inCommunities • Community • energy audits • energy plan • Diesel efficiency • District Heating Ouje-bougoumou

24. Renewable Energy Primary RE Resources Used in Canada: Sun, Water, Biomass, Wind and Earth Energy Sources Renewable Energy currently supplies 17 % of Canada’s energy supply

25. Renewable Energy for Buildings Electricity generation Heating

26. Renewable Energy for Communities Electricity generation District heating

27. Renewable Energy for Off-grid Electricity generation
