The share of wind and solar in total electricity supply in OECD Europe in 2009 was thus 4.3% compared to 1.6% in OECD North America and only 0.7% in OECD Pacific. In individual European countries, the shares are such that they can indeed make a difference to the working of the electricity system. Wind and solar thus contributed 19% to the electricity supply in Denmark, 15% in both Portugal and Spain and 7.3% in Germany during 2009. First, precisely due to intermittency, the total shares of wind and solar power in total electricity supply vastly underestimate their contribution when the wind is actually blowing and the sun is shining.
