ROUND UP ENERGY + ENVIROFICIENCY
Meteorology for Wind
Energy Professionals
Dr Lars Landberg, a meteorologist at DNV
GL, has written a book that will help non-
meteorologists understand the critical con-
cepts that underpin wind energy technology
and project success. The fundamentals of
meteorology dictate the success or failure
of wind projects. The 224-page book starts
with an explanation of howwind forms and
how it is measured. Wind properties such
as flow at all atmospheric scales, turbulence
and wakes are examined, followed by a
discussion on modelling, its resolution and
accuracy. The reader is led through very
simple concepts to more advanced theories
with the use of examples.

EcoTank
Recent and ongoing technical develop-
ments have made it possible to harness the
sun’s energy andmake it easily available for
all to use. Simple plug-and-play products
are shaping the way in which consumers
approach the use of solar as an alternative
and viable option. The recently launched
Ecoboxx 1500 (EcoTank), is capable of up
to 350 hours of power. In addition to pro-
viding enough power to support a small to
medium sized business during times inter-
rupted power supply, the EcoTank is used in
residential and private homes, particularly
in housing estates as an alternative to diesel
generators.

Energy Neighbour
Transmission losses and fluctuations in
electric power grids can be reduced when
renewable energy is stored locally. Re-
searchers at the Technical University of
Munich (TUM) have developed a stationary
intermediate storage system - the Energy
Neighbour. Energy Neighbour increases
the local consumption of generated power,
reduces the load on the grid and facilitates
the expansion of renewable energy produc-
tion capacity. Among its greatest strengths
is its long lifecycle.

Ayanda Nakedi, Eskom’s
‘Wind Energy Pioneer’.
Wind Energy Pioneer Award
Ayanda Nakedi, Eskom’s Senior General Manager for Renewables, was one of the leaders
recognised at this year’sWindaba for their contribution to the industry.
Windaba is the South AfricanWind Energy Association’s (SAWEA) annual conference and at
its gala evening a special accolade of ‘Wind Energy Pioneer Award’ was
bestowed upon Ayanda for outstanding service to the industry.
Ayanda has given a pioneering and sustained contribution to
wind power in South Africa, she has shown leadership in the
growth of the wind industry and her contribution has had
positive impact on the country.
Eskom’s Group Chief Executive, Brian Molefe, said: “She has
indeed been a pioneer, having overseen the commercial opera-
tion of Eskom’s 100 MW Sere Wind Farm, our first utility-scale
renewable energy project. The project was completed on time
and within budget, with a safety record in line with our Zero Harm
policy, and without any environmental legal contraventions
or incidents of industrial action!”

Two countries score triple ‘A’ trilemma score
In its fifth edition, the World Energy Council ’s annual ranking of energy and climate policies - the
2015 EnergyTrilemma Index – registers overall improvements across the three dimensions of
the energy trilemma. However, this year’s report shows that the challenges faced by countries
to develop a balanced approach to their energy policy mean that only two countries out of 130
are achieving ‘AAA’ balance score. Switzerland and Sweden, who top the list, achieve triple ‘A’
score, and while the UK remains in the top ten, it loses its ‘A’ grading for energy equity, moving
it from a ‘AAA’’ to ‘AAB’ status. It is a downgrade that reflects the challenges that countries across
the world are facing in balancing the trade-offs of the trilemma goals and dealing with financing
the transformation of their energy systems.Two new countries have been added to the nega-
tive watch list which in 2014 included German, Italy, Japan and the UK.The countries are South
Africa, due to its electricity crisis, and the US where lack of investment in ageing infrastructure
and exposure to extreme weather events pose threats to the country’s currently strong energy
security performance in the Trilemma Index.The report’s findings show that the best-performing
nations tend to be developed countries with higher shares of energy coming from low- or zero-
carbon energy sources supported by well-established energy efficiency programmes. Every
year, the EnergyTrilemma Index report ranks the energy systems of countries across the world
by giving them a score based on how they are balancing the three dimensions of the energy
trilemma between energy security (a country’s ability to meet its current and predicted energy
demand), energy equity (the accessibility and affordability of energy across the population) and
environmental sustainability (achievement of supply of renewable or low carbon forms of energy).
