Episode notes
Energy-GDP Correlation
- GDP growth and energy use per capita show a strong correlation until the 1970s oil crisis.
- After this, GDP growth continued, but energy use plateaued, raising questions about decoupling and productivity.
Energy Dependence of Physical vs. Service Economies
- Physical processes like material production and transport require energy due to thermodynamic principles.
- Service-based economies, however, have less obvious energy dependence, though subtle effects may exist.
Jevons's Paradox and LEDs
- Jevons's paradox illustrates how cheaper energy leads to increased consumption, not conservation.
- The switch to LEDs, for example, caused people to leave lights on more often due to lower costs.
