This report by UN Environment, the Frankfurt School-UNEP Collaborating Centre, and Bloomberg New Energy Finance, finds that falling costs for solar electricity, and to some extent wind power, is continuing to drive deployment.
The renewable energy market continues to make remarkable progress. Last year was the eighth in a row that global investment in renewables exceeded US$200 billion. Much of this can be attributed to falling costs for solar electricity, and to some extent wind power, which continues to drive deployment. More electricity generated by renewable sources in 2017 signals strong commitment to addressing climate change and reducing carbon emissions.
