2015/2016 Energy Conservation Progress Report

Conservation: Let’s Get Serious

On May 31, 2016, the Environmental Commissioner of Ontario released the 2015/2016 Energy Conservation Report (see Media Release).

This report finds that:

  • Over 80 per cent of Ontario’s energy supply comes from fossil fuels;
  • Ontarians could save $450 million annually through energy efficiency upgrades of broader public sector buildings;
  • Energy conservation is the cheapest source of new energy in Ontario;
  • Ontarians spend far less on natural gas conservation than on electricity conservation, even though electricity is Ontario’s cleanest energy source;
  • Ontario has no meaningful transportation fuel conservation policies; and
  • Ontario’s spends over $600 million in fossil-fuel subsidies annually.

Our Report Cover

Our report cover is a simplified version of a graph in our report that shows actual fuel use of natural gas, transportation fuel, and electricity in Ontario from 2007-2014. To learn more, refer to Figure 2.3 on page 12.

Map of Ontario showing Ontario public sector building energy useEnergy use and emissions for Ontario's Broader Public Sector buildings

The ECO previously posted a map showing energy use and emissions for Ontario’s broader public sector buildings from 2011 to 2013 (see Chapter 4 of this report). However, the data used for this map is now outdated, and more recent data covering 2014, 2015 and 2016 energy use and emissions is available (released in December 2018; though not in map form) from the Ministry of Energy.

The more recent dataset also includes a more accurate method of adjusting reported energy use in schools based on weather conditions during the reporting period (unlike other organizations, school boards report their energy use using a 12-month period that begins on September 1 of each year).

More detail on the methodology used to rank the energy use of facilities and estimate the potential for cost and energy savings can be found in chapter 4 (“Public Buildings”) of the ECO’s 2015/2016 energy report, Conservation: Let’s Get Serious.
