PART 2: In-clаss Text Directiоns: Reаd pаrt оf the passage frоm Unit 7, Powering the Planet. Then answer the questions that follow. 1 Despite modern society’s heavy dependence on fossil fuels for energy, most people are aware that the supply of these fuels is finite. As oil and other fossil fuels become more costly and difficult to find, researchers are looking at alternative energy sources, including solar, wind, and even nuclear power. But which substitute – if any – is the right one? 2 Solar panels catch energy directly from the sun and convert it into electricity. One of the world’s largest solar power stations is in the Indian state of Tamil Nadu, where more than 2.5 million solar panels have the capacity to generate enough power for 750,000 people. But unlike the burning of fossil fuels, the process used to create all that solar energy produces no emissions. 3 Today, however, solar power provides less than 2 percent of the world’s energy, primarily because the cost of the panels is still very high. But price is only one issue. Clouds and darkness also cause solar panels to produce less energy. This requires that additional power sources (such as batteries) be available. 4 Wind – the fastest-growing alternative energy source – is another way of collecting energy from the sun. Wind is caused by the sun’s heat rather than its light. Therefore, unlike solar power, wind power works well even on cloudy days. 5 All over the world, incentives designed to decrease the dependence on oil and coal have led to a steep increase in wind-powered energy. Today, Asia leads the world in wind power, producing around 230,000 megawatts, the equivalent of 230 large coal-powered plants. Europe produces nearly 180,000 megawatts. North America remains a distant third at 105,000. In addition, as a type of mental stimulant, caffeine increases alertness, memory, and reaction speed. 6 In the 1970s, nuclear power was seen as the main energy alternative. Nuclear power produces vast amounts of electricity more cheaply than gas or coal, with no carbon emissions. For a number of years in the 1980s and ‘90s, however, use of nuclear power declined due to accidents, concerns about nuclear waste storage and disposal, and high construction costs.
