Hydropower: the unsung hero of renewable energy

Hydropower accounts for more electricity production than solar, wind, and geothermal combined, but gets far less press because it is a mature technology with a much lower annual growth rate than most renewables. Still, hydropower will likely continue its leading role as the world’s most important producer of renewable electricity until well into the next decade.

This is the 2nd installment in a series that looks at the recently released 2013 BP Statistical Review of World Energy. The previous post – Renewable Energy Status Update 2013 – focused mainly on wind and solar power. This post delves into hydropower and geothermal power. Some of the BP data is supplemented by REN21′s recently-released 2013 Renewables Global Status Report (GSR). (Disclosure: I have been a reviewer for the GSR for the past three years).

Hydropower

Hydropower accounts for more electricity production than solar PV, wind, and geothermal combined. In 2012, hydropower accounted for 16% of the world’s electricity production. However, hydropower gets far less press because it is a mature technology with a much lower annual growth rate than most renewables. While solar PV increased capacity by an average of 60% per year over the past 5 years, new hydropower capacity increased at a much more modest annual rate of 3.3%.
