              years. This in turn will result in less
              stock being available, especially resi-
              dential units. John Loos of First Nation-
              al Bank believes that the demand for
              residential property in the affordable
              market of up to R800 000 will increase.
              This increased demand will lead to
              increased prices in this category –
              while a shortage will drive the prices up
              further. We further believe that land-
              owners that want to dispose of their
              land for development purposes (espe-
              cially unzoned land) will see a dramatic
              reduction in their expected values, due
              to the economy cooling down, the
              increased development cycle, and the
              increases in holding costs for develop-
              ers. These costs cannot just be passed
              on to the consumer; the consumer mar-
              ket is currently very price- sensitive.’
                   Jordaan says he believes that the
              interest cycle is very close to its peak,
              and that we could see reductions in the
              first half of 2009. ‘Taking all of the
              above into account, one must always
              remember that investing in property is a
              long-term journey and not a quick one;
              investors must remain calm and focus

    Wind turbines generate more
    than 1% of global electricity
                                    19.7 GW added in 2007


I
    n 2007, 19.696 MW of new wind
    energy capacity was added sum-
    ming up to a global installed capaci-
ty of 93.849 MW by the end of Decem-
ber. The added capacity equals a
growth rate of 26.6 %, after 25.6 % in
2006. The currently installed wind
power capacity generates 200 TWh per
year, equalling 1.3% of the global elec-
tricity consumption. In some countries
and regions, wind energy already con-
tributes to 40% and more. The wind
industry employs 350 000 people
worldwide, an increase of 50 000 peo-               Figure 1: Total installed capacity (MW) 1997-2007)
ple on the previous year.
     Based on the accelerated develop-
ment, the WWEA has increased its pre-
diction for 2010 and expects
170.000 MW to be installed by the end
of that year. However, in the majority of
the top 40 wind markets, the increase
in the deployment of wind energy
slowed down in 2007.
     Dr Anil Kane, President of the World
Wind Energy Association: ‘The year
2007, all in all, was a very successful
year for the wind industry worldwide.
However, there are several develop-
ments that make us feel concerned: 20
out of the top 40 markets have
decreased the volume of additional
capacity and only 18 countries have                         Figure 2: Capacity installed 2007
been able to increase their size. Anoth-
er concern is that most of the develop-
ing countries are far behind the devel-
opment of the leading wind energy
countries. Today the emerging coun-
tries India and China are amongst the
top five wind markets, and there should
be sufficient motivation for the govern-
ments as well as for international donor
organisations to launch effective and
substantial international deployment
programmes. We need a stronger sup-
port for investment in renewable ener-
gies like wind especially in the develop-
ing countries in order to ensure a truly
sustainable development.’
     In comparison with 2006, when
15.120 MW were added, 2007 brought          Figure 3: Additional wind power capacity worldwide 1998-2007 (MW)

another new record in new installa-
tions. Mainly the booming wind markets
in the USA (5.216 MW of new capaci-
ty), Spain (3.515 MW) and China
(3.313 MW) contributed to this record.
China with a growth rate of 127.5 %
showed the greatest performance of
the top five wind countries. Germany
defended clearly its position as number
one country in terms of overall capacity
with 22.274 MW installed. With addi-
tional capacity of 1.625 MW, Germany
as well as India (1.580 MW added) kept
their positions as leading markets,
however, both countries clearly de-
creased in new installations. Only two
countries (after five in 2006) added
between 500 MW and 1.000 MW and
showed strong growth rates: France                 Figure 4: Total installed capacity and prediction 1997-2010 (MW)
(888 MW, 56.7% growth) and Italy
(603 MW, 28.4%). The most dynamic
market in 2007 was Turkey adding
142 MW up to a total of 207 MW, which
equals a growth rate of more than
200%.
    The market for new wind turbines
reached an overall size of 19.696 MW,
after 15.120 MW in 2006 (30%
increase). In the last ten years,
between 1998 and 2007, even an
almost tenfold increase can be seen.
    Based on this very dynamic devel-        Figure 5: Wind energy capacity added in 2007 by continent (total: 19.883MW)
opment of the past years, the WWEA
has again lifted its prediction for 2010
from 160.000 MW up to 170.000 MW.
    In terms of continental distribution,
Europe decreased its share in installed
capacity from 65.5% in 2006 to 61% in
2007. However, Europe is still the
strongest continent whilst North Ameri-
ca and Asia are increasing rapidly their
shares. In terms of new additional
capacity, Europe for the first time
installed less than half of the new glob-
al capacity and counted for 43.6%, fol-       Figure 6: Total installed wind energy capacity by continent (total 93,9GW)
lowed by North America (28.5%) and
Asia (26.6%).
    The developing countries in Latin
America and Africa counted for only
0.4% and 0.6% respectively of the total
capacity, and Latin America fell back in
terms of new installations down to only
0.2% of the additional capacity installed
worldwide in 2007.
    An important indicator for the vitali-
ty of the wind markets is the growth
rates in relation to the installed capaci-
ty of the previous year. After a decrease
in the average worldwide growth rates
between 1999 and 2004, the growth
rate went up steadily since 2004,
reaching 26.6% in 2007, after 25.6% in
2006 and 23.8% in 2005. However, this
increase in the average growth rate is                Figure 7: Wind energy worldwide annual growth rates (%)

only due to the fact that the biggest
markets – USA, Spain and China
showed growth rates above the aver-
age. Also France showed a very strong
performance with 888 MW added,
equalling a growth rate of 57% in com-
parison to the previous year.

The Journal of Energy in Southern Africa (JESA) has been running for fourteen years, and has proved
 to be of a consistently high standard and to have a widening subscription base. The key receivers of
this quarterly journal are researchers, consulting engineers, energy producers, energy consumers and
                                            decision makers.
  The publication is balanced, representative, up to date and authorative. It is becoming increasingly
                             known in other countries especially in Africa.
The JESA is a successful vehicle for the dissemination of information on the latest results and activities
 in the Southern African energy field, publicising results achieved and stimulating future activities. The
  potential impact in terms of distribution is the whole of sub-Saharan Africa. It covers matters of local
and regional interest as opposed to the internationally high technology content of other journals serving
                                               energy interests.
  It is the intention to keep the subscription rate relatively low to allow as many people as possible to
                                         have access to the JESA.
