One of the key activities in IRENA is the development of renewable readiness assessments (RRAs). An RRA is a holistic assessment of conditions for renewable energy deployment in a country, and the actions necessary to further improve these conditions. An RRA is a rapid assessment of how a country can increase readiness and overcome the main barriers to the deployment of renewable energy technologies. It covers all services (transport, heat, electricity and motive power), and sources of renewable energy, with countries selecting those of relevance. The RRA comprises a process and a methodology that includes completing a set of templates and a final report. On the occasion of the RRA Mauritania, the Global Atlas was presented, as a potential supplier of data, data infrstructure and education for zoning renewable energy hotspots.

What share of my energy mix can
be supplied by renewable energy?
Where are the resources located?
What is the most cost-effective
combination of technologies?
What amount of investments does it
represent? How many jobs ?
Is there a large enough market for
sustaining a supply chain?

7. Winds in Africa. Mesoscale 5km
basemap from 3TIER. Average
annual wind speeds at 80 m high.
The values can not be used
without validation, but the wind
patterns appear clearly, and are
consistent with other mesoscale
sources. The boxes attempt to
highlight areas with possibly
strong annual average wind
speeds.
This rough approximation does
not exclude the possibility of good
wind sites outside the red squares,
due to local effects not captured
by the mesoscale model.

25. Calculation scheme for wind energy yield using
wind speed distributions and power curves
Ei = Annual energy yield of wind class [Wh,
watthours], i = 1, 2, 3 …n
ti = duration of wind speeds at wind class [h/a,
hours/year]
Pi(vi) = Power of wind class vi of wind turbine
power curve [Watt]
vi = wind class [m/s]
PN = Nominal power of WEC [kW] at nominal
wind class vi [m/s]
hi = relative wind class frequency in %
