Obtaining a future based on sustainable energy requires using energy more efficiently in transportation, buildings and appliances. Even If consumption is reduced by one-half, there
will always be a need to obtain new energy sources. If we are to reduce considerably our dependence on fossil fuels, it will be necessary to develop renewable energy sources. The
five sessions of the conference brought together experts (1) on energy policy, (2) on environmental effects of fossil fuels, (3) on transportation, (4) on buildings and appliances and  (5) on renewable energy sources.
