ENERGY SOURCE TECHNOLOGY COMPARISONS

Technology Pros Cons Cost per kWh (cents)
Diesel Generator Technology and infrastructure already exists Combustion leads to pollution and contributes to global warming

Non-renewable and unsustainable

Aesthetically intrusive (noise and smell)
4
Propane Technology and infrastructure already exists

Combustion less polluting than diesel
Combustion leads to pollution and contributes to global warming

Non-renewable and unsustainable
4
Biofuels Minor or no modifications needed to use in conventional diesel engines

Renewable

Clean burning
Ethanol fuel production results in a net loss of energy

Direct competition with land use for food production
4
Solar Produces no waste or pollution

Renewable

Cost steadily falling and production of power is rising

More efficient than biofuels
Not available at night unless battery storage is incorporated

Produces less energy in winter

Solar panels collect dust and snow and must be maintained
20 (technologies available in the near future may reduce this to 3.5)
Micro-hydro Produces no waste or pollution

Renewable
Requires sufficient and constant annual water flow

Not every site is suitable
8
Wind Produces no waste or pollution

Renewable

New designs can withstand heavy winds and gusts

Suitable for most locations
Aesthetics considered undesirable

Noisy

Wind turbines with small blades may negatively affect birds
5
Thermoelectric More efficient than solar and substantially cheaper Electrical potential is small 9


The costs per kWh include the costs of manufacture, shipping, installation, fuel, maintenance, environmental costs and decommissioning (unless otherwise indicated), but do not include costs to transport from road to backcountry.
