As the Commission noted in its autumn 1989 paper on Energy and the En­vironment (COM(89) 369) 'low energy prices acting as a disincentive to energy effi­ciency investments have not changed fun­damentally in recent years and energy is still available in abundant quantities, although this situation is not in line with long­term expectations'.
«Los bajos precios de la energía, que no han variado en los últimos años, han frustrado la inversión en eficacia energética», expone la Comisión en su detallado documento sobre «Energía y medio ambiente» del otoño de 1989 [COM(89) 369].
