File talk:PV growth rate.png

I believe this figure is wrong. Starting from a total PV energy production today of 15 TW*0.011%=1.76 GW, a 40% annual increase would give a total PV energy production after 20 years (ca 2030) of 1.76 GW*1.4^20=1.47 TW. This is 1.47/15=9.8% of the total consumption (assuming consumption doesn't increase), not >20% as the figure suggests in 2030. O. Prytz (talk) 16:21, 11 August 2009 (UTC)
