Achieving a Comprehensive and Integrated Energy System through ElectricityS. Pejovic, pejovics@asme.org, C. Kennedy, christopher.kennedy@utoronto.ca B. W. Karney, karney@ecf.utoronto.ca, Dept. of Civil Engineering, University of Toronto, CanadaT. Maricic, tim.maricic@opg.com, Ontario Power Generation, Niagara , Canada Achievement of, and threat to, modern society is abandon with which energy is used for vehicles, electricity, and space heating/cooling. The very scale of these activities is changing the atmosphere, landscape and even the way we think. Electrical system is key: in the context of transportation and heating/cooling demands, can facilitate a move to cleaner and greener sources. Benefits of energy optimization, efficiency and storage become even more crucial.
Electrification is Underway!15 lead-acid batteries, PFC charger, and regulators installed into WhiteBird, a PHEV-10 conversion of a Toyota Prius Plug-in Hybrid Vehicles Move to electric Vehicles? Potentially large gains in efficiency! But grid implications!
When all units generate at the best efficiency costs are ~minimum – ~lowest price $/kWh Difference between power at high efficiency and design (rated) power is the cheapest spinning reserve. CHEAPEST Spinning reserve Optimisation is not so simple! What is the meaning of optimisation? ?
Complex Implications: Replacement of old refrigerators in Canada:The percentage change of GHG emissions is least for Newfoundland and Labrador (NL) where it represents an increase of 2% of residential GHG emissions in 2002 and greatest for British Columbia (BC) where it represents an increase of 5% of residential GHG emissions
Conclusions: • Nowhere have engineering insights and public policy interacted more strongly than in the intersection of energy, environmental and economic issues • Electricity has great potential as a future energy source for transportation, and likely for almost all other uses. • If generated from non-fossil sources, electricity provides a low polluting means of propelling transportation vehicles. • With advances in vehicle technology, there is potential to exploit the greater efficiency of electric motors over conventional internal combustion engines. • Electricity has to be provided in excess of current demands thereby enabling other energy sectors to shrink • Finally, this can create a new world with many new benefits, but also many new challenges!
