Glede obnovljivih izvora energije moæe se reÊi kako
su mnoge primjene ExternE metodologije pokazale
∑ moæda i znatno preciznije ∑ ono πto se veÊ dugo
nasluÊivalo na temelju prethodno provedenih
studija: ekoloπki troπak ovih tehnologija, imajuÊi
u vidu i Ëitav njihov æivotni ciklus, u prosjeku
je niæi od onog koji u prosjeku nastaje kod
klasiËnih fosilnih tehnologija (ovakav zakljuËak
stoji bilo da se ukljuËe ili iskljuËe najnesigurniji
gospodarski uËinci koji nastaju kao posljedica
efekta staklenika).
Tu su, dakle vrlo valjani razlozi da bi se smatralo
kako πtednja energije i razvoj proizvodnje elektriËne
energije iz obnovljivih izvora energije omoguÊuju
ostvarenje znaËajnog napretka u oËuvanju prirodnog
okoliπa, πto se danas u dovoljnoj mjeri ne
uzima u razmatranje kod izraËunavanja troπkova
proizvodnje. Dakle, ako se pokaæe da je primjereno
korigirati signale koji dolaze s elektroenergetskog
træiπta, neovisno o naravi, tj. ako se poapplee od odabranog
specifiËnog instrumenta intervencije, vaæno
je da ta intervencija bude u korelaciji s ekoloπkom
i/ili energetskom uπtedom. Slijedom reËenog,
program intervencije tijela javne vlasti treba
biti usmjeren poticanju proizvodnje elektriËne
energije iz obnovljivih izvora energije kao i iz
eventualnih drugih neobnovljivih izvora koji donose
energetsku/ekoloπku uπtedu u usporedbi s
energijom koja se proizvodi koriπtenjem klasiËnih
tehnologija ili izvora.
3.2 Tehnoloπka zrelost
PoËevπi od 90-tih godina obnovljivi izvori
energije, uz doprinos ostvarenog tehnoloπkog
razvoja u cjelini, poprimili su sasvim novu vrijednost
u oËima kritiËara diljem svijeta i to ne
kao alternativni izvori (i kao takvi sekundarnog
znaËaja) nego zbog njihove kvalitete s ekoloπkog
stajaliπta. Ovdje treba naglasiti kako prednosti
koje donose obnovljivi izvori energije ∑ a i drugi
izvori koji osiguravaju uπtedu energije ∑ nisu samo
ekoloπke. Kao πto je jasno naglaπeno u Bijeloj
knjizi Europske komisije o obnovljivim izvorima
energije [4] njihov razvoj obuhvaÊa sasvim
novi pristup proizvodnji elektriËne energije,
uz brojne pogodnosti za druπtvenu zajednicu
na makroekonomskoj razini, zahvaljujuÊi prije
svega poveÊanoj sigurnosti, raznovrsnosti izvora i
koriπtenju lokalnih proizvodnih potencijala.
Bijela knjiga EU kao i drugi programi koji uvode
specijalne reæime za te izvore na nacionalnoj
razini (NFFO u Engleskoj, Regimen especial u
©panjolskoj, Stromeinspeisungsetz u NjemaËkoj,
program Eole 2005 u Francuskoj…), pokazuje
kako politiËki predstavnici na nacionalnoj i
nadnacionalnoj razini i te kako uvaæavaju ovakav
Regarding the first point, it is necessary to bear in
mind that if electricity saving occurs due to changes
of the appliances, their environmental impact must
be taken into account too. In other words, a thorough
analysis of the benefits achieved in environmental
protection requires performing a life cycle
analysis (LCA) of other solutions.
Regarding renewable energy sources, it can be said
that many applications of ExternE methodology have
shown − perhaps with significantly more precision ∑
that which has long been suspected on the basis of
previously conducted studies, that the environmental
cost of these technologies, bearing in mind their entire
life cycle, is lower on the average than that which
occurs on the average with classic fossil technologies
(this conclusion is valid whether or not the most uncertain
economic results are included that may occur
due to the effect of greenhouse gases).
There are highly valid reasons for the assertion that
energy saving and the development of the production
of electrical energy from renewable energy
sources facilitate significant progress in the conservation
of the natural environment, which currently
is not being taken into sufficient consideration in
the calculation of production costs. Therefore, if
it is deemed to be appropriate to correct the signals
that come from the electrical energy market,
regardless of their nature, i.e. if one starts from a
selected specific instrument of intervention, it is
important for this intervention to be correlated with
environmental and/or energy savings. Consequently,
the intervention program by the institutions of the
public authorities should be directed at stimulating
the production of electrical energy from renewable
energy sources and also from eventual other nonrenewable
sources that result in energy/environmental
savings in comparison to energy that is produced by
using classical technologies or sources.
3.2 Technological maturity
Owing to to technological advances in general,
from the beginning of the 1990s, renewable energy
sources were reassessed by critics throughout the
world, not as alternative sources (and as such
of secondary significance) but on the basis of
their merits from the environmental standpoint.
It is necessary to emphasize that the advantages
of renewable energy sources, as well as other
sources that provide energy savings, are not solely
environmental. As clearly emphasized in the White
Paper of the European Commission on Renewable
Energy Sources [4], their development encompasses
a completely new approach to the production of
electrical energy, with numerous advantages for the
society on the macroeconomic level, owing first of
all to increased security, the variety of sources and
the use of local production potentials.
