2015 Wind & Solar: SK compared with Top-15 US States

Source: US Energy Information Administration: Electric Power Monthly. SaskPower Annual Report (assumed 2015 wind % same as 2014 since 2015 AR not yet released)

 

The chart shows that the US now generates more than twice as much of their electricity from wind and solar (5.5 percent) as Saskatchewan (2.7 percent). Also of note is that in 2015 Iowa became the first US state to generate more than 30 percent of their annual  electricity using wind turbines.

In 2015 wind clearly dominated and generated 4.7 percent of US electricity versus 0.86 percent by solar.  Nonetheless solar is growing rapidly and in some states in particular: of note is California where solar now generates more than nuclear. Both California and Hawaii now generate more of their electricity from solar than from wind.

 

Wind: Sask. Compared w/ US & Top-10 States 2015 & 2006

 

This chart takes a look at the leading US wind states, at the end of 2015, and compares their wind usage with that 10 years earlier (at the end of 2006). The intent is to show the speed of the wind transition which has been achieved in the US: in other words - what is possible here in Saskatchewan.

 

Source: US Energy Information Administration: Electric Power Monthly; American Wind Energy Association: Year-End Wind Capacity By State (Multiple Years);  NREL Annual Report on US Wind Power Installation, Cost and Performance Trends (Multiple Years).  SK data, in absence of SaskPower AR) assumes 2015 wind % per 2014 (due to fact that no significant wind capacity additions in 2015).

 

For example: in only 10 years the leader Iowa went from 6 percent electricity from wind in 2006 to 31.3 percent at the end of 2015. Our neighbor North Dakota went from 2.1 percent to 17.8 percent. In the same time period wind energy's share in Saskatchewan actually DECLINED from 2.9 percent to 2.7 percent.

How does the rate of increase  seen in these leading states compare with Saskatchewan's plans for 2030? Check this blog post (spoiler: Sask's 25 year transition to 22 percent is none-too-flash by comparison).

 

All forms of Generation: by State

 

..and if you are still after more detailed state-specific information: try this excellent interactive by the Washington Post Information Graphics team ('Mapping How the United States Generates its Electricity' Jul 2015). Select whichever generation type you want and it will then show its usage, by state, in order. Pretty nifty! (N.B.: the data is for January to May 2015 hence may be slightly different than what is shown in the previous charts)
