Energy Externalities Day 2: Gas-fired-CCGT
Day 2 of The Energy Externality Game and we are assessing gas fired power generation using a combined cycle gas turbine (CCGT). In scoring gas we need to take into account the whole of the gas exploration and supply side of the business (which is complex, see below), transportation of gas and the CCGT operation itself. I was a little disappointed in the level of audience participation yesterday, with only 11 participants in total, although the results are very interesting. It would be really good if we could push that beyond 20. Hopefully all of yesterday’s players will play again. Once you get in the swing it takes <10 minutes to compile the scores.
I am proposing to use 12 metrics to measure costs and benefits:
- Fatalities / year / unit of energy produced
- Chronic illness years / year / unit of energy produced
- Environmental costs not covered directly by the system operators
- Foot print of energy system per unit of energy produced
- Energy system costs where energy source transfers costs to the transmission system
- Energy system benefits where energy source provides a service to the transmission system
- Environmental benefits derived from energy system operation
- Taxes raised / year / for total energy produced
- Subsidies paid / year / for total energy produced
- Tax free cost of energy
- EroEI
- Resource availability
For the following 12 electricity generating systems
- Coal-fired (Monday 19 March)
- Gas-fired (Tuesday 20 March)
- Biomass-fired
- Diesel
- Nuclear
- Hydro electric
- Wind
- Solar PV
- Solar thermal
- Wave
- Tidal
- barrage
- lagoon
- stream
- Geothermal
I then go on to provide qualitative assessments of each measure for each electricity system. I have then developed a game whereby we assign a score against each measure on a scale of 1 to 10 where.
-
1=good
-
10=bad
Note that the suggestion to move to a 5 point scale is under consideration and may be adopted, but today we are still using a 10 point scale.
Simply copy / paste the 12 metrics into a comment and add your score.
