The bar graph shows the number of electricity produced by wind power in particular countries—India, Denmark, Germany, and the USA—from 1985 to 2000.
Overall, although in 1985 Denmark had a small amount of electricity generated by wind, the USA’s generated energy was overtaken by Denmark, which showed significant efforts in the area of electricity. It can be observed that both the USA and Denmark experienced noticeable changes. The USA’s total energy depicted some moderate fluctuations. In 1985, the USA generated 1200 megawatts, which increased to over 1600 megawatts over five years. There was a slight dip to approximately under 1600 megawatts in 1995; in the following five years, it declined again to about 1500 megawatts.
Denmark, by contrast, began at a modest 250 MW but more than doubled this figure to around 450 MW in 1990. During the next five years, its production soared to approximately 1,200 MW, and by 2000 it had reached the leading position at roughly 1,650 MW, eclipsing every other nation on the chart.
Turning to the two remaining countries, India’s performance was one of steady and substantial growth. Starting at about 200 MW in 1985, it doubled to 400 MW in 1990, then doubled again to around 800 MW in 1995 before finishing the period at about 1,200 MW. Germany also increased its output, but at a slower pace: from 400 MW initially to roughly 650 MW in 1990, then edging up to 800 MW in 1995 and ending at just under 900 MW five years later.
