Figure 7. Percent change in EROI by scale of operations counted, LCAi to SEA4, error
bars show accumulative variation for input ranges in Table 3. Accounting for larger scales
has declining effect up to the point of adding the environment costs at SEA4.Figure 8. EROI ratios Wh/Wh decrease and LCOE $ prices increase with increasing shares
of the business accounted for. Error bars show the 25th and 75th percentiles for input
variances in Table 2, showing uncertainty proportional to scale as would be expected.
