Elements for sustainable development
resources for innovation is to give a vision about
the future, take into account the experience of the
energy sectors during the last decade, about the
development of the RE, focused from a double per-
spective in terms of regulative and technological.
Depletion of oil resources can be considered
both as a natural and technological risk. This is a
serious risk that deserves all the attention and
efforts of the scientifi c community, responsible
not only to think about alternatives when there
will be no oil but to fi nd solutions for a more
serene economy free from this threat.
Solar energy is the most promising source of
clean, renewable energy, and it has the greatest
potential of any power source to solve the world's
energy problems (Kadir and Rafeeu
2010
). The
energy from sunlight is huge, 0.01 % utilisation
would cover the entire world. This offers a unique
opportunity of technological advancing in the
solar energy fi eld. Indeed, improved access to
clean and green modern energy is a fundamental
step to poverty reduction; with advanced and
technical knowledge and resources, industri-
alised and developed nations can facilitate the
