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.

Green energy comes from diesel.

We use many different energy sources to do work for us. Energy sources are classified into two groups - renewable and nonrenewable. Non-renewable energy sources are those that take millions of years to form and will run out some day. It is energy that comes from fossil fuels such as coal, crude oil, and natural gas. Fossil fuels are mainly made up of carbon and were formed millions of years ago. The chemical reaction which takes place when we burn fossil fuels releases carbon compounds such as carbon monoxide and carbon dioxide into the air. Carbon dioxide is one of the green house gases which is contributing to global warming and air pollution. On the other hand, renewable energy sources will never run out, are better for the environment and do not cause pollution. Renewable energy is often called green energy because it is a natural energy, always available and does not have to be formed like nonrenewable energy. The green energy is always there. For example, the Sun consistently shines, water is abundant, and the winds blow throughout the year. The five types include solar, energy from the Sun; geothermal, energy from heat within the Earth; hydroelectric, energy from moving water; biomass, energy from dead plants and microorganisms and finally, energy from the wind.

Dear guests, I’d like to talk to you today about renewable and non-renewable energy. Fossil fuels are non-renewable energy sources. They include oil, coal, and natural gas. They can be used to create energy, generate electricity, or drive big machinery. Unfortunately, they are harmful to the environment. Viet Nam still relies mostly on non-renewable energy sources, however, hydro power is increasingly used here too.

Hydro and nuclear power can generate a great deal of energy. They are renewable and plentiful. However, hydro power is limited because dams cannot be built in certain areas. Nuclear power can provide enough electricity for the world’s needs, but it is dangerous. The sun and the wind are other alternative sources of energy. The wind turns turbines to

make electricity. Solar power can be converted into electricity. It can be used to heat or cool our houses. Although there are some disadvantages, these alternative energy sources can offer abundant amounts of clean, safe electricity. They will be valued more and more in the future in Viet Nam.

1.How many types of energy sources are mentioned in the text? What are they?

2.What are the disadvantages of hydro and nuclear power?

3.Why do you think the wind and the sun are called alternative sources of energy?

4.What types of energy does Viet Nam use most?

5.What does the professor think Viet Nam will use more in the future?

Our non-renewable energy sources such as coal, oil, and natural gas will (1) __________ out in the future. That's the (2) __________ why we are looking for alternative sources of (3) __________ which are cheap, clean and effective. These (4) __________ of energy will not cause (5) __________ or waste natural resources. (6) __________ power is one of them. It's currently the cheapest source of large-scale renewable energy.

Most wind energy is produced from turbines that have three 60-meter-long blades. The wind spins the blades, which turn a shaft connected to a generator that produces (7) __________. Now, mass production and technology advances are (8) __________ turbines cheaper. In 2000, cumulative wind capacity (9) __________the world was 17,000 megawatts. Fifteen years later, this number increased sharply to 430,000 megawatts. It is predicted that with this pace of growth, (10) in 2050 one third of the world's electricity needs will be fulfilled by wind power.

Are you looking for a cheap, clean, effective source of power that doesn't cause pollution or waste natural resource? Look no further solar energy from the Sun

At present, most of our electricity comes from the use of coal and gas, oil or nuclear power. This power could be provided by the Sun. One percent of the solar energy thet reaches the Earth is enough to provide power for the total population

Many countries are already using solar energy. Solar panels are plaaced on the roofs of a house and the Sun's energy is used to heat water. The energy can be stored a number of days, so or cloudy days you can use solar energy, too

Questions

1. Is the solar energy an effective source os power?

2.Where are the solar panels placed?

3.Is the solar energy used in Vietnam now?
