Its day 3 of the Energy Externality Game already and we move onto biomass-fired-electricity. Most biomass electricity currently resides in Europe, where much of the fuel is imported from North America. In evaluating biomass we need to consider the whole supply chain from timber operations in N America, transport to and from the wood pellet factory, transport across the Atlantic Ocean, off-loading and transport to power station. We then need to consider the externalities associated with power generation.
The Externalities of Energy Production Systems (Day 1 Coal)
Energy Externalities Day 2: Gas-fired-CCGT
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.
