Author highlights the TOTAL (aggregate industry) electricity elasticity as the best/representative estimate and quotes ~-0.4 to -0.5 || 'Calculating simple price elasticity averages gives -0.4 for electricity' (p.728); 'we may quote an elasticity of -0.5 as our best estimate' (p.732); 'we concentrate on the individual elasticities but also include, for its particular interest, the industry total' (p.727). TOTAL electricity = -0.50 (0.09) = obs 2501.
