SUMMARY

The discussion centers on the rising costs of energy resources and the potential for sustainable energy sources to become economically viable. Currently, gasoline is priced at approximately $29 per GJ, and participants suggest that sustainable sources may become cheaper once energy costs reach around $100 per GJ. The conversation emphasizes the importance of understanding energy costs in relation to specific needs, such as transportation and heating, rather than just in terms of gigajoules. Additionally, the declining energy return on investment (EROI) for oil extraction is highlighted, with current ratios indicating a significant decrease in efficiency.

PREREQUISITES
  • Understanding of energy pricing metrics, specifically $ per GJ.
  • Familiarity with sustainable energy sources and their economic implications.
  • Knowledge of energy return on investment (EROI) concepts.
  • Basic awareness of traditional energy sources like gasoline and their market dynamics.
NEXT STEPS
  • Research the economic viability of solar and wind energy at varying energy cost thresholds.
  • Explore the concept of energy return on investment (EROI) in detail.
  • Investigate the current trends in fossil fuel pricing and their impact on renewable energy adoption.
  • Analyze case studies on regions that have transitioned to sustainable energy sources and their cost structures.
USEFUL FOR

Energy economists, sustainability advocates, policymakers, and anyone interested in the future of energy resources and their economic implications.

Is the cost of energy resources for society raising? How high does it have to go to support a switch over to sustainable sources?

There are of course several energy sources we could talk in terms of $ per GJ to normalize them. Gasoline is now at about $29 per GJ. I am making a educated guess that at $100 per GJ sustainables will be cheaper. I would like to hear the communities thoughts.

When researching this I believe it will be more useful to price the cost of that for which energy is needed. That is, people don't want gigajoules per se, they want to travel a mile, take a hot shower, heat their dwelling.

Yes the cost of energy is rising, but I think its better understood from a perspective of a ratio. How much oil does one have to put into a well to get a volume of oil out. At one time, the ratio was pretty high. I don't remember the number, but it was something like 1 barrel of oil in for like 75 out. Today its more like 1 barrel of oil in for 7 barrels out.
