also nuclear and wind become competitive (ExxonMobil, 2009). To be able to
stabilize climate change technology will have to play an important role, it is
therefore important with research and development and eventual deployment
of new, scalable carbon emission-free energies (Hoffert et al., 2002; Green,
2000).

Behavioural change can have as large an impact on emissions as technological
change but can be more difficult to implement socially and politically, in
particular where consumer choice and behaviour is at hand. Buying smaller,
more fuel-efficient cars can reduce fuel consumption directly by 50% or more.
Reducing internal temperatures in buildings can save in the order of 10% of
space heating, more in highly insulated dwellings. Replacing airline flights with
videoconferencing can reduce energy demand for travelling. However, it remains
to be seen if shifting behavior can play a larger role in energy efficiency efforts in
the coming decades (Geller, Philip, Rosenfeld, Satoshi, & Fridtjof, 2006).
For renewables to become a major factor in the electricity production,
policymakers will have to solve several issues in relation to the main renewables
available today. Because solar and wind energy are intermittent as well as dilute,
only a small proportion of these energies, when fully developed, can be supplied
directly to the electric grid. This may to some extent be mitigated by the
development of smart grids, which may reduce the intermittency, diluteness and
distance problems, but will not eliminate them (Green, Baksi, & Dilmaghania,
