For those that think wind and solar are minor contributors to total electricity needs: these two graphs put their current contribution in a local context. The first makes the comparison with Saskatchewan and the second with Canada.
The first chart shows that in 1998 global wind and solar were producing slightly less than total SaskPower generation. However by 2014 global wind and solar were producing more than 38 times as much electricity as Saskatchewan.
This next chart shows that in 1999 global wind and solar was generating electricity equivalent to less than 4% of Canada's total generation. By 2014 the situation had reversed and world-wide wind and solar was generating 30% MORE than total Canadian generation. Not too shabby!
