Energy demand is 4% lower than it would have been without efficiency gains. Between 2015-2018 energy efficiency improvements helped reduce 3.5 Gt of Co2 – roughly equivalent to the energy-related emissions of Japan over the same period. 

Why has energy efficiency fallen:

• Consumers      preferring larger cars – vehicle occupancy rates have fallen
• Residential      buildings – increased device ownership and use, growth in per capita      residential floor area in all economies.
• China      and the US increased their share of industrial production - pushing up demand for primary energy      fuels
• Coal      power generation increased in 2017 (3%) and 2018 (2.5%)

But with COVID-19 oil intensity is likely to go higher - although overall consumption faces a cyclical headwind due to the economy. The per user oil intensity is likely to be higher. Especially with demand for PPE , Face Masks and more protection for packaging food.
