Renewable Energy
gy in Ghana: Prospects
p
and Challenges
g
Renewable energy resources include:
•Solar Power‐ Photo‐Voltaic ((PV)) and Thermal
•Bio Energy‐ Biomass and Biofuel
•Wind Power
•Hydro Power
•Tidal Power and Wave Power
•Geothermal Power
•Fuel Cells
•Hydrogen generation and storage
Renewable energy is site specific and technology driven.
Renewable energy that can be exploited in Ghana include:
Hydro power (mini, micro) solar, biofuels, wind and energy
derived from waste (agricultural and municipal)
Challenges to Future Energy Development Worldwide

•Total petroleum demand is projected to grow from about 1.6 million tones in

• Electricity demand for the domestic market is projected to exceed 4,400 MW in
2020

Wind Energy
The availability depends on the geographical location of
country relative to the equator:
• Countries located further from the equator are known
to have relatively high wind energy potential compared
to cou
countries

•Another challenge is the storage of energy produced

periods
•Wind speeds below 5m/s are considered to be too low
for commercial exploitation

•Along the cost of Ghana wind speeds of 3‐9 m/s have
been recorded and could sustain economic exploitation

Renewable Energy Resources in Ghana
Geothermal Energy
Geothermal energy as in energy derived from heat in the earth
crust has been harnessed for more than a century. Ghana has no
known geothermal energy resource
Solar Power
The sun is the most abundant source of energy in the universe
which can be harnessed in the form of heat or light. The challenge
associated with using solar energy especially for a developing
country like Ghana has been the initial cost of procuring the solar
panels.
Biofuel
This is fuel that is derived from biomass. Unlike petroleum, biofuel
is a renewable resource
resource. Uncertainties in the price of fossil fuel
and concern for the environment has precipitated the need for
biofuel. Experiences
xperiences from countries such as Brazil,
ra il, Malaysia and
Germany show show considerable potential for biofuels.

Intermittent Nature of Renewable Energy and Storage Difficulties
Many renewable energy sources are often dismissed because they
can not be stored and also because they are intermittent.

countries. The general trend is that countries choose feedstock
plants which are already being produced on large scales locally and
which have other commercial value other than the production of
fuel.
In Ghana, Palm oil, Jatropha curcus and Sugar cane offer significant
advantages for biofuel production.
Cost Competitiveness of Biofuel
The biofuel market worldwide is not well developed and biofuels
are not competitive even with crude oil at US$73.00 per barrel.
The global market for biofuel is politically driven and relies on tax
rebates.
