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?

SOLAR ENERGY

Sunlight carries huge amounts of energy. You can feel the Sun’s energy when sunlight warms your skin on a summer day. To capture the Sun’s energy, scientists have developed solar cells, called photovoltaic cells. These cells convert sunlight into electricity. When sunlight hits a solar cell, some of the light energy is absorbed. This light energy causes the particles in the solar cell to move faster, and the movement of these particles creates electricity.

In some places, large panels of solar cells harvest sunshine to make electricity for homes and businesses. Solar cells have been placed on cars and appliances, too. Since the Sun sends abundant free energy streaming toward Earth 24 hours a day, people in many parts of the world, not just the sunniest places, have fixed solar cells and solar panels on the roofs of their houses or businesses to lower their energy costs. Experts say that the huge installation of solar panels in sunny regions could generate enough electricity to supply an entire country. Capturing this energy can help overcome our diminishing energy supply. New ways to capture this energy are being developed an the time to maximize efficiency.

Read the text and complete the sentences using the third conditional.

Some scientists, such as Stephen Hawking, believe it‟s possible that there are billions and billions of universes. Each universe has a different possible consequence for every action. In the universe we live in, for example, George Bush became President of the USA in January 2001, and Greece won the European Cup in July 2004. But in other universes different things happened. Imagine if that‟s true! In some universes, your parents didn‟t meet, so you weren‟t born. In another universe, a meteor didn‟t strike the Earth, so the dinosaurs didn‟t become extinct. In a different universe, your best friend won the lottery last summer and moved to a bigger house. In another parallel universe, you started learning English a year earlier, so you did this book last year! Somewhere else,

Madonna wasn‟t discovered, and so didn‟t make any records. In another universe, Van Gogh was recognised as a great painter during his lifetime, and so didn‟t die in poverty. And perhaps in several universes, there were enough lifeboats on the Titanic and so everyone on board survived. It makes you think, doesn‟t it?
