The bar chart shows the percentage of renewable energy in total energy production in four countries (Australia, Sweden, Iceland and Turkey) in the years 1997, 2000 and 2010. Overall, Sweden and Iceland saw increase in renewable energy over the period shown. Also, Iceland was the country that used renewable sources the most among the four. In 1997, about a half of energy made in Iceland was from renewable resources. This number went up gradually to 60% in 2000 and above 70% in 2010. Sweden also had similar trend, starting with only around 5% in 1997 and increased in the next years. As for Australia, nearly 10% of energy in 1997 came from renewables, but then it dropped slightly to about 5% in 2010. The same pattern happened in Turkey, where the proportion fell from around 37% in 1997 to just below 35% in 2010.

The chart shows average carbon dioxide emissions per person in the UK, Sweden, Italy and Portugal over the period of 60 years since 1967

In general, the UK and Sweden went down, while Italy and Portugal went up across the years.

In 1967 the UK was highest, at about 11 tonnes. Sweden was lower, near 8.5. Around 1977 the UK did not change much, but Sweden hit a high point of roughly 10.5 tonnes. After 1977 both countries fell. The UK dropped to just under 9 tonnes by 2007, and Sweden fell more strongly to a little above 5. It was go down quite a lot.

Italy and Portugal moved the other way. Italy climbed from just under 4 tonnes in 1967 to almost 7 in 2007. Portugal started near 1 tonne and rose steady to around 5 at the end. They maybe will keep rising later. Overall, cuts in the north, growth in the south.
