Wow! In general, charts that have two axises to display trends when there are two different units are hard enough to decipher (temperature and humidity for example). But when the unit is the same (% usage), to use two different scales is just insane. My suggestion: They should change the chart to just have one axis, and have the chart be "% change in usage year over year".

This is roughly what the graph looks like if you change the axis to be % change year over year: http://imgur.com/a/H6T5d http://imgur.com/a/H6T5d

  Could you do a chart with cumulative change over those years?

      It's stacked, not cumulative. Cumulative would be two cumulative running sums (for beer and pot) from the beginning of the period.
