Since a picture paints a thousand words - we'll let the pictures do the talking. First a graph from the Paris-based International Energy Agency which notes that in 2014 renewables made up more than 45 percent of world power generation capacity additions of which 37 percent was wind power and about 33 percent was solar.

The material is taken from the IEA's 'Energy and Climate Change' special report which is packed full of useful information and well worth a read.

All very well but one might ask where things are headed. The short answer? Upwards.

Continued growth of renewables is expected as shown by Bloomberg's informative 'New Energy Outlook' 2015 edition which forecasts that global renewable capacity additions in 2015 will, for the first time, exceed non-renewables.

..and things only get better. Bloomberg expects that, with continued price declines in solar and wind, the global shift to renewables will gather pace such that, by 2040,  renewables will be more than 70 percent of global annual new capacity additions.
