Abstract
It was estimated whether the wood biomass could provide heat demand in the region of Higashihiroshima. And it was shown that if it is possible to use as firewood all growth in forests, heat utilization of the same amount as the current can be achieved in the calculation in a sustained manner for almost all houses in the city. However, actually available quantity will be a one-severalth. Therefore, in order to increase the contribution of wood biomass, reducing the amount of the total energy used by the energy saving is also important. Combustion equipment using firewood has been great progress recently. Then I thought it appropriate to examine the following demand end first; wood-burning stove, some Italian restaurant-bakery of stone oven, farmers who make the plastic greenhouse heating, social welfare facilities. In order to raise the ratio of renewable energy further, it is thought that it is necessary also perform energy saving and to make a change of a system.
