Conclusions

the availability and use of energy around the world is extremely

heterogeneous

fossil fuels are dominating at present, but must be replaced in the

long run

there is still a big gap in energy services between industrialisedand developing countries

utilisation of renewable energy technologies is increasing, as is

research on these subjects
