Profitability of Dutch greenhouse firms is largely dependent on energy costs, and policy makers focus on reducing the use of energy by these firms. This article uses Russell measures of TE to develop indicators of energy productivity growth. Results show that energy productivity grew by 2.8% annually in the period 1976-95, with technical progress being the key factor driving the process of productivity growth. From this we conclude that policies aiming at enhancing the adoption of technological innovations are more effective, if due attention is paid to measures for improving TE.
