The problem is none of these articles provide numbers that allow you to grok what's actually going one. Probably because journalists are innumerate. You have a total 4X10^12 kwh/year of production, that's energy. 50 GW that's power. Wtf!!!??? Teasing it out I think. Solar you get probably 5 hours a day. Wind maybe more? eh, lets assume 5 hours. 5 hours a day, 1825 hours a year. So 50GW... lets say 50Mkw instead. 50X10^6 kw X1825 hr/year => 91,250,000,000 kwh/year How does that compare to current production? Percent added is 9.125X10^10/4X10^12 = 0.0228 or 2.23% Seems like a small amount but it's growing exponentially. If it increases by 25% a year then you'll be adding 5% a year of renewables per year in 5 years.
