Energy efficiency and energy conservation aren’t the same thing, but they have a similar (25): to reduce energy
use. Here’s the difference. Energy conservation relies on people cutting back on activities that (26) energy—by
turning off lights or driving less or using appliances less often. Energy efficiency harnesses technology to help
avoid or reduce energy (27) so that you can still turn on the lights, drive, or wash your clothes but use less energy
doing so. Why is it important to use less energy?
Using less energy through (28) measures is good for the economy and your wallet. By reducing the (29) of
energy required for certain tasks, energy efficiency is also good for the planet. It can help to reduce air and water
pollution (30) by certain types of energy generation and avoid negative impacts on critical ecosystems.

Are you looking for a cheap, clean, effective source of power that doesn't cause pollution or waste natural resources? Look no further than 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 that reaches the Earth is enough to provide power for the total population.

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

Sweden has an advanced solar energy program. There, all buildings will be heated by solar energy and cars will use solar power instead of gas by the year 2015.

Question: Is solar energy an efficient source of power?

Decide if the following statements are True or False or Not Given according to the text.

Hello students. Today I'd like to tell you some information about types and sources of energy. Energy is classified into two main groups: renewable and non-renewable.

The energy generated from natural sources such as the sun, wind, rain, and tides is called renewable energy. They are plentiful and can be generated again and again. They also have low carbon emissions so they are considered green and environment-friendly. Moreover, using renewable energy can reduce your electricity bills. Unfortunately, solar energy can be only used during the daytime but not during night or the rainy season. Geothermal energy also can bring toxic chemicals beneath the earth's surface to the top and can create environmental changes.

 

Non-renewable energy is the energy taken from other sources that are available on earth. They are limited and will run out in the future. They can't be re-generated in a short time. Fossil fuels - natural gas, oil and coal - are examples of them. They are cheap and easy to use. However, when burnt, they release toxic gases in the air so they cause serious environmental changes such as global warming. And the important thing is that non-renewable sources will expire someday.

This text may be written by a teacher.

A. True

B. False

C. Not Given
