THREAD: In 2005, the official Annual Energy Outlook saw power sector CO2 rising from 2,400 to 3,000 MMT by 2020. But actual emissions fell to 1,450 MMT, 52% below projected levels. A new @BerkeleyLab report looks at how we got “halfway to zero.” emp.lbl.gov/publications/h… 1/11 
The biggest change was drastically less demand for electricity, due in part to sectoral and economic changes, but also to greater energy efficiency driven by policies and technology advancement. Instead of rising by 24% it was dead flat. 2/11
And as demand stayed flat, cheaper natural gas from the shale gas revolution combined with the rapid growth of wind and solar power to squeeze out coal. Some nuclear retirements were offset by greater output at existing plants. 3/11
