Directions (11–15) : In the following passage there are blanks, each of which has been numbered. These numbers are printed below the passage and against each, five words/phrases are suggested, one of which fits the blank appropriately. Find out the appropriate word/phrase in each case.
One big difference between the investments in fossil fuels and those in wind power, solar cells, and geothermal energy is that the latter will supply energy in (11). These “wells” will never run dry. If the money spent on oil in one year were invested in wind turbines, the electricity generated would be enough to meet one-fifth of the world’s needs.
Investments in infrastructure for the new energy economy, which would eventually have to be made when fossil fuels reserves (12), will obviously be huge. These include the transmission lines that (13) wind farms with electricity consumers, and the pipelines that link hydrogen supply sources with end users. To a substantial degree, the infrastructure for the existing energy sources -the transmission lines for electricity from coal and the pipelines for natural gas can be used in the new energy economy as well. The local pipeline distribution network in various cities for natural gas can easily be (14) to hydrogen distribution system. For developing countries, the new energy sources promise to reduce dependence on imported oil, freeing up capital for investment in domestic energy sources. (15) very few countries have their own oil fields, most have wind and solar energy. In terms of economic expansion and job generation, these new energy technologies are a godsend.
