The bar chart provides information about the percentage of renewable energy in the total energy production in Australia, Sweden, Iceland and Turkey between 1997 and 2010.
Overall, Iceland was the country that produced the highest rate of renewable power, in contrast to Australia and Sweden in the three given years. Also, the primary feature that the statistics present is the distinct general trends. While Iceland and Sweden observed an increase in producing renewable energy, Australia illustrated a decrease, and Turkey showed variations in this.
In terms of the ratio, Iceland reported around 45% of green power produced from its energy source up to a whopping 70% provision of that in 2010, making this nation the most green power providing one over the period. By contrast, the data recorded for Australia and Sweden never reached 10% on the scale, performing the minimal figures in this. Whereas, in Turkey, renewable energy indicated the fluctuations between 33% and 40% of the total energy source, coming second.
Regarding the growth in renewable energy generation, a similar pattern can be witnessed in Iceland and Sweden, with an extensive escalation of 25% and an insignificant rise of 3%, respectively. Australia, however, performed an opposite trend due to the slightly decline of about 3%. Meanwhile, there was a steady fall in renewable power provision in Turkey, starting at 37%, after which it demonstrated a grow of modestly 40% in 2000, before reducing to 32% at the end of the given period.
