Energy Externalities Day 6: Hydroelectric Power
Hydroelectric power produces no pollution once the dam is built and the valley flooded. It is dispatchable and widely regarded to be the “Rolls Royce” of renewable energy. Based on trapping rainfall produced by solar energy trapped in high valleys that were created by plate tectonics that is driven by spontaneous nuclear fission within the lithosphere. The Sun and The Supernova combine to produce this ultimate limousine of the energy world. But how do the costs and benefits of this silver ghost really stack up against nuclear, gas and wind?
The Externalities of Energy Production Systems (Day 1 Coal)
Energy Externalities Day 2: Gas-fired-CCGT
Energy Externalities Day 3: Biomass-Fired-Electricity
Energy Externalities Day 4: Nuclear Power
Energy Externalities Day 5: Wind Power
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
