Between years 1990 and 2004, an increase has been observed in the overall energy consumption by around 23 percent with the consequent total increase in the GHG emissions by 24 percent in all sectors. With the ratification of the Kyoto Protocol in 2002, Canada committed to reduce its GHG emissions by at least 5 percent between 2008 and 2012 on the basis of its 1990 emission levels. To meet this target, Canada has to evaluate and exploit every feasible meaning to reduce fossil fuel energy consumption and consequent GHG emission while maintaining its economic growth and standard of living. One of the strategies to reduce the fossil fuel consumption and associated GHG emissions is to increase the use of renewable energy. This study focuses on the feasibility of using the photovoltaic (PV) and roof-mounted wind turbines in the Canadian residential sector. Representative test-case Canadian houses were developed in ESP-r using the data from three of Canada's most comprehensive housing stock and residential end-use energy databases. Annual simulations were run to estimate the space heating, domestic hot water heating and electricity demand of these test-case houses. The total GHG emissions due to thermal and electrical energy use were estimated along with the cost of electricity at flat and time-of-use (TOU) rates. The houses were upgraded and integrated with PV and roof-mounted wind-turbine energy systems. The annual simulations were run again to estimate the renewable energy produced by using PV and wind-turbine energy systems. The reductions in GHG emissions due to electricity contribution of these systems to house electrical demand were estimated. The cost of annual electricity consumption was estimated at flat and TOU prices. The credit of selling the surplus electricity to the local grid was also estimated. The results were extrapolated at national level to assess the potential of GHG reductions using these systems in Canadian residential sector. It was found that using these technologies in the selected test-case houses can result in the GHG reductions between 4.1 to 4.4 Mt at the average emission intensities and between 11.9 to 12.7 Mt at high emission intensities. The surplus energy produced by these systems can contribute to meet the demand of local power supplier to further reduce the GHG emissions. | | Subject | : | Applied sciences; Mechanical engineering; Energy; 0791:Energy; 0548:Mechanical engineering | | Added Entry | : | Dalhousie University (Canada) |
