No single headline electricity elasticity is given; authors describe electricity as the most inflexible energy form with low own-price elasticity, and explicitly disavow the positive chemicals value as perverse. Preferred = the negative, statistically-significant own-price electricity elasticities the authors treat as valid. || 'the observed low own-price elasticity for electricity, ranked fourth among the energy types, is explained by the fact that electricity, used mainly for lighting and motive power, is the most inflexible form of energy' (p.1675); 'The positive own-price elasticities in the chemicals industry are rather perverse' (p.1674)
