1.    People come out of houses almost bare-bodied and sit in the open places. Some splash cold water on their faces.
2.    It is impossible to sit in the study without electricity in the night with a candle light or
table lamp or hurricane lamp or a rural kerosene lamp,
1.    Last night Sohan could not sleep due to power shortage.
2.    The summer night was sticky hot.
3.    During load shedding most of their area remained dark for hours.
4.    The shortage in electricity production causes load-shedding.
5.    The current demand for electricity is more than 6,000 MW.                         !
 
22.Model Question
1.    a, i) Future energy problem; b. ii) fire wood; c. i) its store is limited; d. i) green energy; e, iii) issue of energy; f. iii) 3 per cent; g. i) 335; h. iii) is not according to our need; i. ii) the sun; j. i) green energy.
2.    a. Science Congress is an organization where the scientists express their research activities.
3.    Mr APJ Abdul Kalam is the former president of India.
4.    Mr APJ pointed out the necessity of green energy.
5.    The scientists were afraid of the shortage of energy in the coming decades.
6.    Massive burning of world’s coal reserves may cause ecological disaster.
7.    Mankind can look to the massive use of solar energy because it has some advantages over other forms of renewable energy.
8.    Global economic growth is expected to continue at 3 per cent per year.
9.    The energy consumption by 2030 will rise to 335 million barrels.
10.    The present reserve of hydro-carbon energy resources is limited.
11.    Yes, solar energy may be called green energy. It is not like natural gas.
23. Model Question
1.    a. ii) two; b. finish c. i) natural source of heat and light; d. iii) the environment; e.ii) Hydrogen; f. i) electricity; g. i) Heat from deep within the earth; h. ii) hydroelectricity.
2.    a) Renewable energy sources are the energy sources which are constantly and naturally replenished and will never run out. Sun, wind, flowing water, biomass, geothermal energy are sources of renewable energy.
3.    b) Non-renewable energy sources are costly. Fossil, oil, coal, gas etc. are non-renewable energy sources.
4.    c) Our Earth’s interior contains molten lava with tremendous heat.
5.    d) Hydrogen and Oxygen remain in water.
6.    e) Hydrogen is separated from another element. It is the most abundant element in nature. But it does not exist separately as a gas. It can be burned as a fuel to produce electricity.
7.    f) Hydroelectric energy can be captured with wind turbines to produce electricity. The wind and the sun’s heat cause water to evaporate. This water vapour turns into rain or snow and flows downhill into rivers or streams.
8.    g) The most renewable energy comes directly or indirectly from the sun. Sunlight or solar energy can be used for heating and lighting homes, for generating electricity.
9.    h) Plants need to grow rain and, sunlight etc.
10.    i) We get biomass from plants. Because plants produce biomass which again can be turned into fuels such as fire wood, alcohol etc.
11.    j) Re-newable energy sources never run out because renewable types of energy can be used again and again. They are constantly and naturally replenished.
