CONTENTS
MAY–JUNE 2011 VOLUME 14 NUMBER 3
REGULARS
From the editor ............................................. 4
News analysis ................................................7
Featuring a review of the UK’s offshore wind turbine market;
India’s renewable energy challenges; China’s green growth and
IP concerns; Asia’s burgeoning wind market; and a review of the
global wind turbine blade market.
Company results ......................................... 72
A roundup of the latest nancial results from the world’s leading
renewable energy companies.
Diary ............................................................ 79
Advertisers’ index ....................................... 80
THE LAST WORD
The UK’s budget, insurance,
and Fukushima ............................................. 75
A swathe of natural disasters topped off by Japan’s earthquake
and tsunami will undoubtedly see insurance companies hike
premiums in a bid to claw back cash after some big payouts with
developers having to work harder still to cut costs in both Europe
and further aeld.
By Fraser McLachlan
FEATURES
Balancing on the edge ................................. 21
The outlook of one of the PV industry’s success stories looks
precarious as Italy’s government seeks to shield its consumers
from the escalating cost of a surge in renewables. Is the sector on
the brink?
By Jackie Jones
World wind energy outlook ........................ 29
Worldwide wind capacity reached exceeded 196 GW in 2010, of
which more than 37 GW was added that year alone. Global
installed capacity is now potentially able to generate some
430 TWh annually, equivalent to 2.5% of global supply. The global
industry is reviewed in a snapshot in this report.
By Stefan Gsänger
Targeting solar CSP .....................................37
A generous tariff regime as well as high insolation has driven
spectacular growth in CSP deployments in southern Spain. The
challenge is to drive down costs through economies of scale and
new technologies so that CSP can one day stand subsidy-free.
By Geoff Nairn
On dangerous ground ................................. 46
The Fukushima-Daiichi nuclear disaster in Japan has led to
another round of worldwide soul searching about the safety of
nuclear power. Yet, all forms of generation pose some danger.
REW looks at how various generation technologies fare and
explains why solar and wind excel when it comes to safety.
By Elisa Wood
Solar hybrids ............................................... 52
Capable of harnessing more solar energy than the sum of their
constituent parts, hybrid photovoltaic-thermal (PV/T) technologies
have been surprisingly slow to catch on. But for those companies
developing systems for market, the rewards are potentially huge.
By Chris Webb
Bringing big guns to bear
........................... 58
The military has long been at the forefront of new technologies but
with costs being squeezed and the supply of hydrocarbons having
a negative impact on its ability to ght, reasons for its involvement
in the development of renewable energy technology have never
been more compelling.
By Richard Baillie
Italy’s multi-technology PV eld...................66
Situated in Italy’s Bolzano Dolomiti airport is the country’s largest
PV experimental eld. With a total of 24 different technologies
installed, the project allows the performance of various
commercially available PV technologies to be assessed.

I
n its latest Clean Energy Progress report the International Energy Agency (IEA) has
again highlighted the pernicious inuence of fossil-fuel subsidies on the continued
growth of the renewable energy sector.
According to the report, fossil fuels currently receive some US$312 billion in
consumption subsidies, versus $57 billion for renewable energy. And this is just one
of the issues which sees the competitiveness of renewable energy largely lag that of
their fossil-based rivals.
Certainly, renewable energy technologies are making visible progress – wind and
solar PV have achieved considerable success for instance – but achieving clean
energy goals will require a doubling of renewable energy use by 2020 and thus
renewable energy growth rates must be sustained in the long term. Furthermore, with
signs that austerity plans are weakening policy support, comes the observation that
fossil fuel-based energy development continues to outpace that of renewables.
Global renewable electricity generation since 1990 has grown at an average of 2.7%
per year, the IEA says, less than the 3% growth seen for total electricity generation.
Consequently, while in 1990 19.5% of global electricity was produced from
renewables, this had fallen to 18.5% by 2008.
But, as ever, global events continue to overtake policymakers and impacts on the
world’s energy complex – such as the surging oil price and renewed questions over
nuclear following the Japanese earthquake and tsunami – may yet accelerate a shift
in balance in favour of renewables.
Indeed, IEA Executive Director, Nobuo Tanaka, recently noted: ‘The age of cheap
energy is over. The only question now is, will the extra rent... go to an ever-smaller
circle of producers, or will it be directed back into the domestic economies of the
consumers, with the added benets of increased environmental sustainability?’
We explore some issues that inform this debate in this edition. For example on page
46 we take a look at the potential implications arising from disasters such as that in
Japan as we attempt to assess the potential cost benets of a distributed renewable
energy generation system.
To coincide with our own Renewable Energy World Europe conference and
exhibition, which takes place in Milan, Italy, on 7–9 June this year, we present an
overview of the country’s renewable energy scene on page 21, and on page 66 a
report on a new PV testing facility comparing 24 different technologies.
We also consider a possibly unlikely source of renewable energy technology
development in our feature on renewables in the military, beginning on page 58, and
take a look at a number of emerging technologies with a feature on the latest CSP
developments in Spain.
Please also look out for the two special supplements which are being published
together with this edition. In our latest Wind Technology we present all the latest in
the world of wind and this is joined by Large Scale Solar, a new publication which
provides detailed articles on this dramatically changing industry.
Renewables will no doubt continue to face fearsome challenges on their long road to
grid parity, and while there aren’t necessarily any short cuts, the path may have got
just that little bit easier.
