The plan was perceived with the goal of CONSERVING ENERGY. While in the process of researching and developing a pollution control technology, they found a way to cut fuel consumption by one-third and avert the greenhouse affect. The method used was the cogeneration of heat and electricity which they believed was the best way to conserve energy and protect the environment. Apart from cogeneration, Helsinki also generates most of its energy from imported fuels since the country's own energy reserves are limited to peat and wood chips. The DH network is hightly efficient with a small rate in heat loss, through the production of heat in power and heating plants.
The process of developing and implementing the District Heating system was achieved through the cooperation of the producers--heating companies, consumers, and the government. The process began in the 1950's with difficulties in gaining recognition from the consumers and government; but, today it is a successful enterprise owing to the fact that it is both economically and environmentally sound.
