在线课程【答案】The pie charts present the changes of the percentages of the energy produced from various sources in our country from 2007 to 2017.
Apparently, oil was the most dominant source from which the energy was produced, although its percentage dropped from 52% to 39%. Likewise, nuclear also declined, becoming the third primary source of energy. The percentage of natural gas, on the other hand, witnessed the most noticeable increase during the period, rising from 13% to 23%.
Coal and other renewable resources saw the rise of 5% and 3% respectively. Interestingly, the proportion of the energy produced from the hydrogen, though not widely used, remained stable. Overall, this trend helps guarantee sustainable economic growth, improve the environment and reduce the cost of living.
To my mind, we should enforce the use of other renewable resources such as solar energy, wind energy and water energy to protect our limited resources.
