Every aspect of modern society – food, housing, education, health, the economy, and government – runs on energy. In 2018, Londoners and London’s employers spent almost $1.6 billion on energy. Almost 90 percent of this money leaves London.
Through conservation, efficiency, and more local energy production, we can keep more of that money here in London. In 2018, it is estimated that $160 million in energy costs were avoided through energy efficiency (using 2010 as a baseline).
Most people think of electricity when they hear people talk about energy. However, for London, natural gas is the largest source of energy we use, accounting for 45 percent of our annual energy needs. Gasoline comes second at 24 percent of our needs. Electricity, as important as it is, accounts for just 19 percent. Diesel, propane, and fuel oil account for the rest.
In Ontario, most of our electricity is made from emissions-free sources such as nuclear power, hydro-electric dams, wind, and solar. However, natural gas is still used to generate electricity during peak demand periods.
Most of our energy needs are being met by fossil fuels (natural gas, gasoline, etc.) – finite resources that contribute to greenhouse gas (GHG) emissions as well as air pollution. London’s Community Energy Action Plan has the following goals for reducing London’s GHG emissions:
- 15% reduction from 1990 levels by 2020,
- 37% reduction from 1990 levels by 2030, and
- 80% reduction from 1990 levels by 2050.
In 2018, total GHG emissions in 2018 were over 3.1 million tonnes, which is 9 percent lower than 1990 levels. Weather has an impact on energy use and, in 2018, London had a colder winter and hotter summer compared to 2017. Using a three-year rolling average evens out the impact of weather. The three-year rolling average for the 2016-2018 period was 13 percent below 1990 levels.
