6. 12 % Renewable by 2020
The GoL has set a target of 12% renewable energy by 2020.
To achieve this goal, the MoEW has been working on various initiatives with
numerous Stakeholders ( BDL, EDL, La Kadisha, LWA, CDR, MoE etc …) with the
support of many funds & international cooperation agencies (UNDP‐CEDRO, AFD,
World Bank, Spanish Cooperation, Italian Cooperation, Greek Cooperation etc …) :
‐ Wind Energy : Market Study, Capacity Building, Wind Atlas, Pilot Wind Farm.
‐ Solar Energy : Study PV Potential, Study CSP Potential, Pilot PV Farm.
‐ Hydro Energy : Hydro National Assessment, Micro Hydro Pilot Study, Hydro
Rehabilitation, Micro Hydro Pilot Projects, Feasibility Studies for New Hydro.
‐ Waste to Energy : Study WTE from WWTP Sludge, Study WTE from MSW.
‐ Geothermal Energy : Geothermal for Heating/Cooling Pilot Project, Geothermal
Atlas.

7. What is Geothermal Energy ?

8. What is the Geothermal Energy
potential of the Earth ?
o Enough thermal energy exists in our planet to run
civilization for billions of years
o More energy available in the earth than oil, coal, gas,
and mineable nuclear fuels combined
o The Earth's geothermal resources are theoretically
more than adequate to supply humanity's energy
needs, but only a very small fraction may be
profitably exploited as drilling and exploration for
deep resources is very expensive.

9. Earth Temperature Gradient
Boyle, Renewable Energy, 2nd edition, 2004
Outside of the seasonal variations, the geothermal gradient of
temperatures through the crust is 25–30 °C per kilometer of
depth in most of the world.

10. What is the use of Geothermal Energy ?
o Heat pumps extract energy from shallow sources at 10‐20 C in 43 countries
for use in space heating and cooling. Home heating is the fastest‐growing
means of exploiting geothermal energy, with global annual growth rate of
30% in 2005 and 20% in 2012.
o Sources with temperatures from 30‐150 C are used without conversion to
electricity for district heating, greenhouses, fisheries, mineral recovery,
industrial process heating and bathing in 75 countries.
o 28 Gigawatts of direct geothermal heating capacity is installed for district
heating, space heating, spas, industrial processes, desalination and
agricultural applications in 2010.
o Sources with temperatures from 150‐300 C can be used for Electricity
Generation. Currently, 26 nations use geothermal power for electricity
production. In 2012, total global capacity was 11,400 megawatts.

16. Why Geothermal Electricity ?
o Geothermal energy is a renewable energy source because earth’s heat is being
constantly replenished by the radioactive decay of minerals at a rate of 30 TW.
o High Reliability: Once in operation, is the most reliable energy source. Most
geothermal facilities that has been built in the last 100 years are still in production.
Moreover Geothermal energy don’t need a storage solution in order to work reliably.
o High Availability: Geothermal energy is available 24 hours a day, 365 days a year.
Geothermal power plants have average availabilities of 90% or higher, compared to
about 75‐85% for other types of plants.
o High Capacity Factor: Geothermal energy supply does not suffer from intermittency as
it is unaffected by changes in weather or night cycle/day. It is constant & without limits.
It has a Capacity Factor close to 100% higher than any other renewable energy
technology (ie: Wind Farms 20‐40%, PV Farms 13‐20%, CSP 33‐63%, Hydro 25‐68%).
o Increase of Energy Security : Geothermal energy is not dependent on fuel sourcing,
market changes, transports & logistics risks nor weather conditions. It is thereby a
valuable contributor to the Country’s energy security.

17. Moreover
o Small Footprint: Geothermal has minimal land requirements. Geothermal plants use
3.5 square kilometres per gigawatt of electrical production (not capacity) versus 32
square kilometres and 12 square kilometres for coal facilities and wind farms
respectively.
o Minimal Freshwater requirements. Geothermal use 20 litres of freshwater per MW∙h
versus over 1,000 litres per MW∙h for nuclear, coal, or oil.
o No Harmful Emissions : Being a renewable source of energy, geothermal energy has
helped in reducing global warming and pollution. Geothermal wells release greenhouse
gases trapped deep within the earth, but these emissions are much lower per energy
unit than those of fossil fuels.
o Fixed Cost : Once in operation, Geothermal Energy is immune to fuel cost fluctuations.
o Least visual impact of any power generation technology available.
o Low Maintenance requirements.

18. However typical Barriers are
o High Upfront Costs. Reconnaissance, Exploration & Drilling accounts for high costs.
However, the cost of geothermal power has decreased 25% over the past two decades.
o Risk of Failure : Exploration of deep resources entails significant risks as drilling for
Geothermal may have a 20% failure rate.
o Suited To Particular Regions. Conventional Geothermal power plants are currently cost‐
effective only in areas near tectonic plate boundaries.
o Not Widespread Source of Energy : Since this type of energy is not widely used
therefore the unavailability of equipment, staff, infrastructure, training pose hindrance
to the installation of geothermal plants across the globe. Not enough skilled manpower
and availability of suitable build location pose serious problem in adopting geothermal
energy globally.
o Environmental Concerns. Groundwater contamination can be a problem if the
geothermal wells were not well sealed at great depths cement and steel tubes.
Hazardous gases and minerals can seep up from beneath the ground, and finding a way
to safely dispose of them may prove very difficult and dangerous.
