“Will The Real Global Economy Please Stand Up”
I’ll start with Japan and work my up progressively larger. The population data is from the UN and I use the 15 to 60 year old population to avoid speculation about changing birth rates over the next fifteen years. Energy data is from the US Energy Information Administration (EIA) and their projections using their IEO’17 (International Energy Outlook, 2017) models.
Japan
- Core population peaked 1993, declined 14% since (as of 2015), will decline 22% by 2030 and 33% by 2040.
- Energy consumption peak 2006, declined 17% since
- My est. -25% by 2030, -30% by 2040
- IEO’17 est. +3% by 2030, unchanged by 2040.
Germany
- Core population peaked 1995, declined 5% since, will decline 17% by 2030 and 19% by 2040.
- Energy consumption peaked 2006, declined 14% since, will decline 22% by 2030 and 28% by 2040. IEO’17 data will be wrapped together for EU below.
Italy
- Core population peaked 2005, declined 4% since. Will decline 17% by 2030 and 25% by 2040.
- Energy consumption peaked 2005, declined 17% since. I estimate declines of 26% by 2030 and 32% by 2040.
Greece
- Core population peaked 2006, declined 5% since. Will decline 15% by 2030, 29% by 2040.
- Energy Consumption peaked 2007, declined 27% since. I estimate declines of 40% by 2030, 47% by 2040
