instance, co-incineration of scrap materials as a substitute
for combustibles in the manufacturing sectors).
Hence, by the end of Phase A in about 2025, worldwide
CO 2 production can be successfully stabilized at 30 – 32
Gt CO 2 per year. 5 World population is then 7.5 – 8 billion.
Phase B (medium-term — until roughly the middle
of the century)

The true costs relating to the resource “climate” have
been established. The low-temperature heat sector has
been extensively decarbonized in a growing number of
countries. The power generation network finds itself in
a state of major change between 2020 and 2045. By
this time, the mix of primary energy sources already
consists of a high proportion of CO -free gas- and coal-
2
fired power plants as well as of renewable energy
sources (solar, wind, hydropower), at best even geothermal
energy. Should Generation IV bring proof of
the inherent safety of nuclear fission, as well as of the
minimization of radioactive waste and proliferation
while clearly improving fuel efficiency, one can expect
it to increase its contribution to the power supply. A
significant commercial contribution from fusion by the
end of Phase B is rather improbable.
Electricity storage technologies experience a commercial
breakthrough between 2020 and 2050. Biomass is
used primarily for steady-state applications and in
smaller plants (
