Conveniently, in 2040 all sources of production these all add up to about 103 quadrillion BTU, so you can also treat the Y axis as % (same for 2016). But note that in 2040 we’re still 80% fossil: (35 for liquids + 33 for natural gas + 11 for coal). This snapshot was taken in 2016, so this likely only considers policy decisions baked since 2015, though I suspect things won’t change much. OK, so if we’re at 76% fossil for 2040, where were things in 2016? Not much is different: In 2016, about 81% of our energy came from fossil, and in 2040 the gov predicts about 76% will come from fossil. Now, the carbon intensity difference of coal versus natural gas is huge: about 2:1. That is, one BTU from coal results in twice as much CO2 being emitted versus natural gas. But make no mistake, fossil will be a huge part of the equation for the next few decades. https://static1.squarespace.com/static/582b933a2994cab6e0ce7761/t/5d3f1977564f7300016e9eef/1564416383563/eia_comparison.png Blog - Domestic Energy Consumption Through 2040 https://www.narrowband.org/blog/2019/12/21/just-how-bad-is-flying monthly 0.5 2019-12-21 https://www.narrowband.org/blog/2019/12/23/coal-the-decades-ahead monthly 0.5 2019-12-24 https://static1.squarespace.com/static/582b933a2994cab6e0ce7761/t/5e0160297645b07c0606a7cf/1577148466388/bpoutlook.png Blog - Coal the Decades Ahead https://www.narrowband.org/blog/2020/2/9/nuclear-learning-rates monthly 0.5 2020-02-09 https://www.narrowband.org/welcome daily 1.0 2018-01-09 https://static1.squarespace.com/static/582b933a2994cab6e0ce7761/t/5a5524c424a694cec112e64e/1515529459482/narrowband.jpg Welcome https://static1.squarespace.com/static/582b933a2994cab6e0ce7761/t/583f1d5c9de4bb33ef7ca530/1480531293142/SA+40+mvpp.JPG Welcome https://www.narrowband.org/contact daily 0.75 2018-01-12
