The October Energy Efficiency Blog will give an introduction to climate change.
What is “Global Warming”, and how does it relate to Climate Change?
Global warming is the rise in overall average global temperature, and is the result of an increased concentration of Carbon Dioxide (CO2) in the atmosphere. The earth is heated by the sun; incoming solar radiation bounces back into space, but a small portion of it is trapped by the delicate balance of gases –the “Greenhouse Gases” (GHG) - that make up our atmosphere. Through the alteration of the concentrations of these gases, the atmosphere has begun to trap a greater amount of solar radiation leading to Global Warming.
The increase in average global temperature has resulted in a change in the natural climate patterns, this includes: increase in ocean temperature and acidification, sea level rise, glacial retreat, polar ice retreat, and changes in climate extremes (floods, fires, droughts, tropical storms, etc). A major concern of these changes is habitat destruction for animals and humans, as well as reduced agriculture area and output.
What are Canada and Alberta doing as a result?
Canada has committed that by 2030, we will cut our emissions by 30 per cent from 2005 levels. Part of this reduction will come from phasing out electricity from burning coal (10% of Canada’s electricity). Ontario completed a phase out of coal electricity in 2014 replacing it with cleaner sources of power, and Alberta plans to phase out coal power by 2030. A large focus has been put on increasing efficiencies in both our electricity markets, and transportation sectors.

What can I do on a local level?
The two largest GHG emitters we use in Alberta are vehicles and electricity generation. Every day in Canada, 11.4 million people drive to work, if each person burns 1L of fuel, this results in 2622 tonnes of CO2 emissions. A solution is to reduce the amount you drive, in a way that is most convenient; walking, biking, and carpooling are all great, but not often practical. Consider more efficient route planning, public transit, and eliminating non-essential travel.
Similarly with electricity, small use by a large number of users can add up. There are fewer than 1 million people between the age of 15 and 55 in Calgary. If only 75% of those people have a phone, simply by charging our phones, we use around 5000 kWh each day; resulting in 3-4 tonnes of GHG emissions daily. Consider ways to reduce your electricity consumption that are practical, such as shutting down computer workstations not in use, and using high efficiency lighting and appliances.
