  13. Energy Sources next • introduction Hey Baby Kevin, Relax! It's not the end of the world! After all, the sun will still shine, and you can always count on it for solarenergy! You can tap solar energy using photovoltaic cells (in solar-powered calculators) or using the solar-thermal method like what we do in the Mojave Desert. We have over 1800 mirrors arranged in 100 acres of land to reflect sunlight onto the top of a tower. I heard Singapore’s sunny just like California. Can’t you use solar energy? Look on the BRIGHT side, George, USA • contents • section A • section B • section C George Bolshevik Xiaoping Shatshwa prev page page quit

  14. Energy Sources next • introduction Dear Baby Kevin, Singapore has great demand for energy indeed! Have you considered using nuclear energy? The amount of energy generated will be tremendous and readily available. Furthermore, a nuclear plant doesn't take up much space. Aren't these just what Singapore needs? However many people are terribly against it because of the many problems it entails, amongst them, nuclear waste disposal and the possibility of accidents. Well, what do you think? Do think thrice, Bolshevik, Russia • contents • section A • section B • section C George Bolshevik Xiaoping Shatshwa prev page page quit

  15. Energy Sources next • introduction Dear Baby Kevin, I’m sorry to hear of the crisis! Here in Chongqing, the huge dam at the Yangtze River provides us with hydroelectric energy. Hydroelectric energy is clean, steady and cheap (at least after the dam was built!). My grandfather said the dam was also built to curb the disastrous river floods that killed many people. However, I was told many historical sites, natural habitats and village settlements had to be flooded to create the reservoir behind the dam. But do you think Singapore can generate hydroelectric energy? Let nature take its course, Xiaoping, China • contents • section A • section B • section C George Bolshevik Xiaoping Shatshwa prev page page quit

  16. Energy Sources next • introduction Dear Baby Kevin, In Africa, biomassenergy has always been a way of life. Biomass energy is stored in all plants, animals and organic matter. There are many ways of generating biomass energy. A long time ago, it just meant burning wood or animal dung. Now, you can grow energy crops like sugar cane and oil palms for fuel. Also, decomposing matter like rubbish emit combustible gas that we can use. There're lots of possibilities for biomass energy. Do you think Singapore can use any of them? NATURALLY yours, Shatshwa, South Africa • contents • section A • section B • section C George Bolshevik Xiaoping Shatshwa prev page page quit

  17. Energy Sources • introduction Sigh! It’s really too late for Baby Kevin to do anything, isn't it? Luckily, we are still in 2001 A.D. and there's still time. However we do need to think seriously about developing alternative sources of energy don’t we? What alternative sources of energy can Singapore consider for her future? • contents • section A • section B Energy • section C prev next page page quit
