Renewable energy set new records in 2015 for dollar investment, the amount of new capacity added and the relative importance of developing countries in that growth. All this happened in a year in which prices of fossil fuel commodities – oil, coal and gas – plummeted, causing distress to many companies involved in the hydrocarbon sector. So far, the drivers of investment in renewables, including climate change policies and improving cost-competitiveness, have been more than sufficient to enable renewables to keep growing their share of world electricity generation at the expense of carbon-emitting sources. The following renewable energy projects are included: all biomass and waste-to-energy, geothermal, and wind generation projects of more than 1MW; all hydropower projects of between 1MW and 50MW; all wave and tidal energy projects; all biofuel projects with a capacity of one million litres or more per year; and all solar projects, with those less than 1MW estimated separately and referred to as small-scale projects, or small distributed capacity, in this report.
