United Nations officials say the use of energy from sun could help agricultural areas in developing countries. They say that the use of solar technology could greatly improve the lives of millions of people. Solar technology systems use energy from the sun to make electric power. Solar energy now is used mainly in homes. It supplies power for electric lighting, radios and TV. It is also used to heat water. The UN Food and Agriculture Organization says now is the time to develop other uses for solar energy. Nowadays almost two thousand million people in developing countries still have no electric power. In general, most poor farmers will not be able to purchase solar power systems. However, solar energy can provide some important social services for people in developing countries. They include water supply systems and cooling devices to store medicines.

1. What can people get from the sun with the solar technology systems? …………………………………………………………………………………….

2. Will most poor farmers be able to purchase solar power seytem? …………………………………………………………………………………….

3. Where is solar energy now used mainly? …………………………………………………………………………………….

4. What is solar energy used to do? …………………………………………………………………………………….

5. What can solar energy provide for people in developing countries? …………………………………………………………………………………….

Solar energy is a long lasting source of energy which can be used almost anywhere. To generate solar energy, we only need solar cells and the sun. Solar cells can easily be installed on house roofs, so nonew space is needed and each user can quietly generate their own energy. Compared to other renewable sources, they also possess many advantages: wind and water power relies on turbines which are noisy, expensive and easy to break down. Solar cells are totally silent and non-polluting. As they have no moving parts, they require little maintenance and have a long lifetime.

However, solar energy also has some disadvantages. We can only generate solar energy during daytime because the system depends on sunlight. Besides, solar cellsrequire large area to work effectively. The main disadvantage of solar energy is that it costs about twice as much as traditional sources such as coal, oil and gas. This is because solar cells are expensive. Scientists are hoping that the costs of solar cells will reduce as more and more people see the advantages of this environmentally friendly source of energy.

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.
