Four key parameters were used in the research: Enabling framework, financing and investment, value chains, and greenhouse gas management, and 71 markets were looked at, which includes 72% of the global population. Over two hundred data points per country were analysed, from 15,000 individual pieces of data.
Overall, there has been a large jump in the number of solar installations globally, although the number of investments has gone down. This is especially the case in China and is due to the cost of solar coming down and the investment in on-shore wind going up.
Using the four key parameters, the Index shows the profiles of 71 countries with the top five positions including China, Brazil, Jordan, Mexico, and India. The larger countries are generally doing better, but Jordan is a good example of a smaller country doing a lot in terms of investments and employment. While China scores the highest at just above 2.5, the top of the scale is at 5, so there is still a lot of room for improvement.
The biggest movements in 2016 include countries that have had a drop in their score. This is the first time any drops have been recorded since this report started, which is largely due to the cutback in global investment. Most notable among these is Uganda with a 0.57 drop. Uganda has always been a top performer because of their government incentives, but has dropped this year due to policy change, with no replacements to previous incentives. Other countries that have seen a score drop include the Latin America region, mainly due to saturation, and potential investment fatigue. The full report looks further into how quickly they can progress despite these issues.
One of the biggest increases in score comes from Barbados, thanks to its large integration of renewables to the grid. Other high performers include Senegal and Jordan, who did not have high access to fossil fuels like their neighbours, so the money they were spending on importing fuels is now being spent on domestic renewables.
The Paris Agreement has been incorporated into the methodology, with scores reflecting the commitments made – these are likely to change over the coming years. For more insight and the full report see here.
