Greenhouses use various kinds of energy. Three quarters of all the energy used is generated with natural gas. About 10% of natural gas consumption in the Netherlands is used for horticulture.

The cost of natural gas in the greenhouse horticulture sector during the period 2004 to 2007 doubled from more than 400 to more than 800 million euro. The expectation is that this will rise to 1,275 million euro in 2010. At the same time, the government are demanding drastic savings in energy consumption. For the greenhouse horticulture sector, a resolution has been made between the sector and the government (GLaMi, a Long-term Agreement regarding the Environment for the Greenhouse sector).

GLaMi energy targets for 2010 are: Improvements in energy efficiency of 65% compared to 1980 and an increase in sustainable energy usage of 4%. These targets have been interpreted into individual company norms and have legal implications in terms of the Greenhouse Sector Resolution.

Thermatras® Thermatras® insulation blankets offer an excellent solution for reducing inefficient natural gas usage. By reducing heat loss, energy efficiency will improve and overheads for the heating of large greenhouses will come down. Short cost recovery times for insulation blankets in this sector are therefore achievable.
