There is an overall decline in energy use between the Business as Usual Scenario of year 2016 and the Low Carbon Scenario of year 2050. The largest change in energy use is apparent in the use of natural gas with a decline of 110 Petajoules. Although energy use declines overall by the Low Carbon Scenario of 2050, electricity in the 2050 Low Carbon Scenario becomes more prominent, and there is approximately a 32 Petajoules increase in electric generation . The transition to local and more efficient energy generation and energy consumption result in a decline of conversion losses of approximately 78 Petajoules – a significant improvement. For more information about the projected energy shifts, refer to TransformTO: Climate Action for a Healthy, Equitable and Prosperous Toronto - Report #2 - The Pathway to a Low Carbon Future.
