Extract

Long-term limits to growth in energy-use will be imposed not by inability to expand supply but by the rising environmental and social costs of doing so. These costs will therefore be central issues in choosing long-term energy options. Energy from nuclear fusion, like solar energy, is not one technology but many. Some of the fusion possibilities seem likely to have very attractive environmental characteristics; others may be little better in these regards than nuclear fission.

Issues in fusion-reactor design that are crucial from the environmental standpoint include: size of tritium inventory and pathways for its release; nature and configuration of materials that are subject to neutron activation; forms and quantities of the stored energy that are internal to the reactor, and the nature of potential links between fusion technology and nuclear weaponry.
