Figure 2
Comparison of electricity cost, GHG emissions, and overlap with high-conservation-value areas across potential run-of-river hydro, wind farms, and shale gas development. The cost of enegy production is the weighted mean cost of development ($CAD/MWh) across all potential locations. The overlap with high-conservation-value areas is the proportion of cells with Zonation rank > 0.7 that is overlapped by the infrastructure and development footprint for each energy source. GHG emissions are the per unit energy estimates of CO2 from lifecycle analyses for run-of-river hydro and wind farms, and the sum of combustion and upstream emissions (e.g. extraction, processing, and transport) for shale gas development.
