footprint.

3/ Reading
I. 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.
1. Energy use is the main reason that causes carbon footprint in Canada.
2. David Suzuki is the CEO of Bullfrog Power.
3. David Suzuki wants to find a solution to climate change.
4. Green energy comes from diesel.
5. The technology uses solar energy to replace natural gases.
II. 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 of power.
1. From which do plants on the earth get energy?
A. stars
B. the Mars C. the moon D. the sun
2. What are the other words or phrase for fossil fuels?

III. Read the passage and answer the questions given.
Energy Sources
Energy is very important in our daily life. We use energy to turn on lights, cook food, and run
machines. There are two main types of energy: renewable energy and non-renewable energy.
Renewable energy comes from natural sources like the sun, wind, and water. Solar energy
comes from the sun. Wind energy comes from the wind, and hydro energy comes from moving
water. These types of energy do not run out and do not pollute the environment.
Non-renewable energy comes from fossil fuels like coal, oil, and gas. These fuels are limited
and can cause pollution. Many countries are trying to use more renewable energy to protect the
Earth.
Using renewable energy is a good way to save our planet. People are installing solar panels
and wind turbines to create clean energy. In the future, we may use mostly renewable energy.

5. Many countries invest in renewable energy to protect the Earth.
III. Write a paragraph about an energy source you are interested in. (*)
Eg:
I am very interested in solar energy because it is a clean and renewable source of power. Solar
energy comes from the sun and can be harnessed using solar panels. These panels absorb
sunlight and convert it into electricity, which can power homes, schools, and businesses. The
best thing about solar energy is that it does not cause pollution, unlike fossil fuels such as coal
and oil. Additionally, solar energy is renewable, meaning we will never run out of sunlight as
long as the sun exists.
However, there are some challenges with solar energy. One of the main issues is the high cost
of installing solar panels. Also, solar energy only works when there is sunlight, so it cannot
generate power at night or during cloudy days. Despite these challenges, many countries, such
as Germany and China, have made significant investments in solar energy and are using it
effectively to reduce pollution and protect the environment. I believe that solar energy is the
future of clean power and will play a key role in solving the world's energy problems.
