Renewable energy: Harnessing the power of nature
In Canada, the electricity grid is relatively green with low-emission sources of energy flowing in from hydro-rich provinces, such as Quebec and B.C. In fact, hydroelectric energy comprises nearly two-thirds of the power generated in Canada each year.
Walmart Canada taps into this energy stream and also currently sources some its electricity needs through a renewable provider named Bullfrog Power. In fact, we increased our wattage purchased to become Bullfrog Power’s second largest commercial customer in Canada – reaching 46,965 MWhrs.
Investing $2 million in renewable innovation
Our first core environmental goal is to be supplied 100 per cent by renewable energy. In August 2011 we took concrete steps towards achieving that aspirational goal – by investing $2 million in two separate projects to test the viability of solar power and wind energy.
Roger Snowball, director of design at Walmart Canada outlined the objectives, “These pilot projects allow us to test new technologies in a real-world setting, so that we can apply the best practices and learning to new stores in the future.”
Boosting wind power
We’ve also installed an 80-foot high, 20-kilowatt wind turbine next to our Milton, Ontario store. This particular type of turbine is designed for low wind speed areas, where the technology has not previously proven practical.
- Designed to operate in wind speeds as low as 10 kilometres per hour.
- Expected to produce 32,000 to 35,000 kilowatt hours per year based on wind variations – enough to power three average size households.
