The bar chart demonstrates how much wind energy (in megawatts) was produced by four different countries – India, Denmark, Germany and the USA – between 1985 and 2000.
Generally speaking, all the countries studied saw increases in their energy output from this source, with the US being a distinctive dominant in all years but 2000. The most significant change, however, was observed in Denmark, where the amount outstripped that of the US by the end.
From 1985 to 1990, the US obtained significantly more wind power than the other countries. Its quantity rose from about 1200 megawatts to a chart peak of 1600 megawatts during this period, which was roughly three times the figure for this closest follower Germany in each year. Reliance on wind as a power source in Denmark and India was even lower, yet similar, with the figures growing by more or less 200 units to just under 500-megawatt mark in 1990.
Thereafter, the trends shifted markedly. The dominance of the US came to a halt by the end of the period with 1500 megawatts, by which time Denmark had exhibited a precipitous rise to approximately 1600 megawatts, overtaking the US. Meanwhile, India also managed to treble its amount by the final year to around 1200 units, ranking third, whereas Germany’s growth was consistently steady, thus ranking last with only about 900 megawatts.
