Day 031 — Writing Task 1: 折れ線グラフ（1人当たり電力消費量 3か国比較）

The line graph illustrates the changes in per capita electricity consumption (measured in kWh) in Japan, Brazil, and India over a twenty-year period from 2000 to 2020.

Overall, Japan maintained the highest level of electricity use throughout the period, though it followed a generally declining trend after 2005. By contrast, both Brazil and India recorded steady increases, with India showing the most significant proportional growth. Despite these trends, a considerable gap between Japan and the other two countries remained by 2020.

In 2000, Japan's per capita consumption stood at 7,800 kWh, which rose marginally to a peak of 7,950 kWh in 2005. However, it subsequently fell, reaching 7,600 kWh in 2010 and declining further to 6,900 kWh by 2020. Brazil, in contrast, saw a gradual but consistent rise from 1,900 kWh in 2000 to 2,700 kWh in 2020.

India began the period with the lowest figure of just 450 kWh but experienced the strongest relative growth, more than doubling to 1,100 kWh by 2020. While the gap between the three countries narrowed over the period, Japan's consumption remained roughly six times that of India in 2020.
