These bulbs use a (17) of the electricity of standard bulbs and last eight times (18).

Read the passage, and choose the correct answer A, B, C or D for each question.

Almost all our energy comes from oil, coal, and natural gas. We call them fossil fuels. The earth’s fossil fuels are running out. What will happen when there is no oil, coal and gas on the earth?

Scientists are trying to find and use other alternative sources of energy. We can use energy from the sun, the wind, and the water.

Solar energy is unlimited. The sun supplies all the energy used to grow plants, to evaporate water for rain, and to maintain the temperate of the planet. All are necessary for human life. If we are able to collect solar energy, we will be sure to have this abundant source od power.

Choose the word or phrase among A, B, C or D that best fits the blank space in the following passage.

In Western countries, electricity, gas, and water are not (11) but necessities. Companies now realize that consumers want (12) that will not only work effectively, (13) save money.

For most North American households, lighting (14) for 10 percent to 15 percent of the electricity (15). However, this amount can be (16) by replacing an ordinary 100-watt light bulb with an energy-saving bulb. These bulbs use a (17) of the electricity of standard bulbs and last eight times (18). Therefore, consumers can save about US$7 to US$21 per bulb. In Europe, there is a labeling scheme for refrigerators, freezers, washing machines and tumble dryers. The label tells the consumers how much energy efficiency each model has, compared (19) other appliances in the same category. Ultimately, these innovations will save money as well as (20) the earth’s resources.

Read the passage, and then tick the correct answer true (T), or false (F).

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 clean 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.

Ultimately, these innovations will save money as well as (20) the earth’s resources.
