Abstract
Operating a tissue culture or micropropagation laboratory is highly energy intensive because of the need to maintain below ambient temperatures and provide artificial lighting. This contributes to the cost of plants produced through micropropagation. Energy conservation measures that can be adopted in a typical micropopagation loboratoty are discussed. Reduction of operating costs by efficient utilisation of air-conditioned space and the use of alternate lighting systems such as sunlight and solar photovoltaic systems is suggested
