Did you know that energy use is the biggest contributor to fine average Canadian home's carbon footprint? That's why the David Suzuki Foundation and Bullfrog Power are partnering to offer you a quick and easy way to switch your home to clan energy and be part of the solution to climate change. When you choose green energy, Bullfrog's generators put clean, renewable electricity and/or green natural gas (produced from organic waste, not fracking) into the grid or pipeline to match the amount of power or natural gas your home uses. Bullfrog ensures the energy going into our energy systems - on your behalf -is from clean, green sources. Bullfrog’s green electricity comes from a blend of wind and low-impact hydro power from new Canadian renewable energy facilities, with at least 50 per cent directly from your region.

Energy use is the main reason that causes carbon footprint in Canada.

A. True

B. False

XV. Read the passage and answer the question.

A carbon footprint is the amount of carbon dioxide (CO₂) released into the air by your own energy needs. You need transportation, electricity, food, clothing, and other goods. CO₂ is produced by the burning of fossil fuels which is used to provide energy for your homes, by the cars you travel in and by the manufacture and transport of goods you buy.

Carbon dioxide is also called greenhouse gas, which causes global warming. That is the reason why the carbon footprint is a very poweful tool to understand the impact of personal behaviours on global warming. If you want to contribute to stop global warming, the reduction of your personal carbon footprint is essential. Fist, you can reduce your carbon footprint by driving less. When possible, walk or ride a bike to avoid carbon emissions completely or use public transport in order to decrease CO emissions. Second, support using clean energy sources such as wind, solar, geothermal energy and biogas. Finally, reusing or recycling items you no longer use is also a good way to reduce your carbon footprint.
