(0.1&amp;#x2F;0.07 = 1.42)&lt;p&gt;This is great news! In about 75 years, we&amp;#x27;ll use &amp;gt;90% renewable energy. (1.42^(x&amp;#x2F;12) = 0.9&amp;#x2F;0.1)&lt;p&gt;Which of these is the better model? I don&amp;#x27;t know, I can&amp;#x27;t eyeball statistical regression on this chart. But my gut says percentage of energy use growth isn&amp;#x27;t what we should pay attention to if we want to predict the long run future. When&amp;#x2F;if renewables become far cheaper than coal, that percentage is going to skyrocket fast.</text><parent_chain><item><author>josselex</author><text>So renwable Energy increased from 7 percent to 10 percent in 12 years with a perfect linear slope.
So we just need only about 300 years till 100%.
Good luck with that.&lt;p&gt;Is anybody reading these plots? This is really the worst news I read this year.</text></item></parent_chain></comment><story><title>Ways the world improved in 2018</title><url>https://qz.com/1506764/ways-the-world-improved-in-2018-in-charts/</url></story>

Sorry, but agriculture is hugely environmentally impactful. We should not be growing fuel. I think a lot of it is subsidized by governments. Extracting petroleum from the ground is going to continue to be cheap for a very long time.</text><parent_chain><item><author>josselex</author><text>So renwable Energy increased from 7 percent to 10 percent in 12 years with a perfect linear slope.
