However,in some parts of the world such as China there are huge coal reserves which are only now being mined and used in power stations. In this case coal may still be a good investment but be bad for the environment.e)Wave power has many of the same pros and cons as wond power.f)Nuclear power has attracted bad publicity in the past but more recently many governments have returned to the idea of building nuclear power stations in the next century in order to solve the potential shortage of energy. Private investment may yet provide good returns.Reading:Good greed2(P110)1 B 2 B 3 A 4 C 5 D 6 B 7 C 8 D 9 A 10 B 11 B 12 A 13 D 14 A 15 C3(P78)The graph shows that while solar power costs twice as much per kilowatt-hour than traditional energy sources used on power grids at present, its costs have been falling continuously since the early nineties. The line showing the average price for power from the grid for residential energy is also climbing. If these trends continue, solar power may become very competitive, making it a good long-term investment.Vocabulary: Describing trends4(P78)(1) peak(n)(2) rising(v)(3) soar(v)(4) remained stable(v)(5) crash(n)(6) go down(v)(7) descent(n)(8) declined(v)Listening:Reasons for trends1(P112)A no speakerB 2C 4D 3E 1F 52(P112)(1) because(2) due to the fact that(3) Another reason for(4) as a result of(5) asWriting:A proposal4(P113)Reasons for:-it has a new deal with Mainline Energy worth 190 million euros-the company has over ten years experience in a relatively new field-it hit a high earlier in the year-the recent fall is described by many analysts as a short-term problem.-it has developed a new silicon-saving technologyReasons against:-its recent stock price fell by half-there is a shortage of silicon5(P113)Dear Mr Keating,In response to your enquiry about Sungreen Power, the company seems to be performing well.One thing to consider is their new sales agreement with Mainline Energy, worth 190 million euros. This should help their share price which recently halved. On the one hand this was caused by a shortage of silicon, but on the other hand Sungreen specialise in technology which requires less silicon.So despite the fall, I would still suggest you consider investing. The fact that solar power costs have continously fallen since the early nineties and look set to equal normal energy costs in the next few
