Globally, the continuous increase of energy consumption coupled with the depletion of the limited fossil fuel sources and their negative impacts on the environment, has shifted focus towards renewables for a sustainable development. For the last fifteen years, the world has enjoyed renewables generation capacity increases in a double-digit Terawatt-hours range. Although renewables consumption is fast developing in Asia Pacific, Europe and North America, significant coordination efforts are required among stakeholders in sub-Saharan Africans countries such as Cameroon. In 2018, the total final energy consumption in Cameroon was 7.41 Mtoe, 74.22% of which was from biomass, 18.48% from fossil fuels and 7.30% from electricity. Furthermore, 6977 GWh of electricity was produced, 78.29% of which from the major electricity operator (ENEO S.A. Cameroon) and 21.71% from independent producers (GLOBELEQ, ALTAAQA Sinohydro China and AGGREKO). More than three quarter of electricity produced were consumed by industry (57.04%) and residential (20.74%) sectors. The country's installed electricity generation capacity rose to 1402 MW, 56.15% of which was from hydropower, 43.84% from fossil fuels (17.55% from natural gas and 26.29% from oil) and 0.01% from solar photovoltaic. The promotion of renewable energy is an important part of Cameroon's plan to increase energy security and provide job opportunities to the country. Yet, the lack of proactive and long-term renewable energy policy and laws, in addition to less attention paid to renewable energy training and research, financing mechanisms, and unaffordable costs of renewable energy technologies to the poor population are amongst present issues hindering the development of renewable energy in the country. Hence, this paper aims to highlight the present status of renewable energy exploitation and development in Cameroon.

For decades, the world has witnessed a sustained increase in energy demand added to faster depletion of coal, natural gas, and crude oil reserves as well as cumulative negative impacts of fossil fuels to the environment. In 2018, the share of world primary energy consumption by source was oil at 34%, coal at 27%, natural gas at 24%, hydro at 7%, nuclear at 4% and renewables (solar, wind, geothermal, biomass, etc.) at 4%. Driven by higher energy demand, the world's primary energy consumption rose 2.9% to reach 13,865 MTOE, 85% of which from fossil fuels, while global energy-related CO2 emissions showed a growth rate of 1.95% to a historic high of 33 891 MTOE .This energy crisis situation has driven the world towards renewable energy (RE) sources, which are immensely available and have the potential to efficiently satisfy an appropriate portion of the world energy needs, while minimizing environmental pollution and health hazards associated with the use of coal, natural gas, and crude oil .
In recent decades, the shift focus towards RE for a sustainable development has led to a double-digit growth rate increase in renewables consumption worldwide [3–5]. For the last fifteen years, renewables consumption worldwide showed annual growth rates ranging from 12.52% in 2005 to 19.30% in 2011, and reached 2480 TWh, 1.3% of which consumed in Africa . Asia Pacific (40.2%), Europe (30.7%) and North America (21.2%) represented the biggest renewables consumers. Despite a relative low share of renewables generation consumption, Africa has seen higher renewables consumption, mainly in the last seven years, with growth rates that ranged between 10% in 2012 and 56% in 2015. The Africa renewables generation rose 19% to reach 32 TWh in 2018. South Africa was the biggest renewables' consumer (38.8%), followed by Eastern Africa (27.1%), Morocco (15.0%) and Egypt (10.9%) . In the remaining sub-Saharan African countries such as Cameroon, renewables generation consumption is still low despite the huge and essentially untapped potential .
Therefore, the objective of this paper is to renew interest in RE and advocate for its development in the country. The originality of this paper lies in assessing main sources of energy as well as highlighting the most recent data on final energy consumption by sector and by source. Furthermore, this paper aims to raise awareness of crucial stakeholders on the present status of energy, RE potential and status of exploitation, RE policy and legal, RE education at school level, and barriers and keys recommendations for the dissemination and development of RE in Cameroon.
The world 53rd largest country, Cameroon covers a surface area of 475 442 km2 of which 60% can be used to grow crops . Cameroon is located between 2°–13° North latitude and 8°–16° East longitude. As a consequence, it has a wide range of climatic types: Sudano-Sahelian, Tropical humid, Equatorial monsoon and Guinea equatorial. The Sudano-Sahelian zone is characterized by nine months of dry season and three months of rainy season. In this zone, higher temperatures, ranging from 35 to 45 °C, are experienced throughout the year . In March, April and May, temperatures can rise over 45 °C, while in December and January temperatures can fall below 10 °C. The Tropical humid zone shows a spread of rainfall over a period of five months on average, while the other months of the year are dry. The Equatorial monsoon zone, which spans from coastal area around the South Region and covers part of the West region, is characterized by heavy annual rainfall. The Guinea equatorial zone is found in the southern part of the country, characterized by a high relative humidity due to continuous rainfall throughout the year and high temperatures.
The country is bordered by Central African Republic (CAR) to the east (797 km), Chad to the northeast (1094 km), Nigeria to the west and north (1690 km), Congo (523 km), Gabon (298 km) and Equatorial Guinea (189 km) to the south. Its coastline spans from the Bight of Biafra to part of the Atlantic Ocean in the Gulf of Guinea (402 km). Figure 1 illustrates the geographical location of Cameroon, including its borders and neighboring countries.

The population of Cameroon is estimated at about 24.628 million people at the end of year 2018 , of which 3.58% in the Eastern region (East Region), 34,33% in the Northern regions (Adamaoua, Far North and North regions) and 62.09% in the Southern regions (Littoral, North West, West, South, and South West regions). The density of population in the country has progressively increased from 37.5 person/km2 in 2005 to 49.9 person/km2 in 2018. This density is disproportionately distributed across the country, with 8, 52 and 80 person/km2, respectively in the Eastern, Northern and Southern regions. The Country's electrification rate was around 61.4% in 2017, with 93.2% and 21.3%, respectively, of urban and rural population having access to electricity . The electricity consumption level in the country averages 198 kWh per capita per year, while this level is less than 43 kWh/capita/year in the northern regions (Northern Interconnected Network), around 68 kWh/capita/year in the Eastern Region (East Network) and nearly 291 kWh/capita/year in the Southern regions (South Interconnected Network). Northern and eastern regions have very low levels of energy access (respectively, less than 30% and 40%) and other basic services, such as literacy rate, basic sanitation, potable water. In 2018, the gross domestic product of Cameroon was approximately $38.675 million, with a growth rate of 4.06% and a per capita income of $1534, with a growth rate of 1.38% .
Cameroon's energy consumption shows that biomass, electricity and petroleum are three main sources of energy. Biomass consumption accounts for 74.22%, followed by petroleum (18.48%) and electricity (7.30%), as illustrated by Figure 2. In 2018, the total final energy consumption in the country was 7.41 Mtoe and was dominated by traditional forms of biomass.
The residential sector shares 63.68% of the total final energy and depends largely on biomass. The Commercial and public services (14.92%), transport (13.82%), industry (5.15%) and agriculture / forestry sectors (0.07%) rely on petroleum and electricity. Figure 3 illustrates the share of energy consumption by sector.

Grid electricity is the leading source of modern energy in the country. Hydropower, natural gas and oil fuels are the major sources of electricity. The country's installed electricity generation capacity at present is approximately 1402 MW, 56.15% of which is from hydropower, 43.84% from fossil fuels (17.55% from natural gas and 26.29% from oil) and remaining from solar photovoltaic (PV) . Several utility companies are involved in the electricity generation in the country, namely ENEO, GLOBELEQ, ALTAAQA, Sinohydro China and AGGREKO. ENEO, the major electricity operator, has an installed capacity of 1010 MW, 73.49% of which from hydropower, 26.49% from oil fuel and 0.02% from PV solar. Independent producers, namely, GLOBELEQ (86.08 MW) , ALTAAQA (216.00 MW) and AGGREKO (10 MW) generate electricity from oil fuels and natural gas. The current 45 MW of Sinohydro China (hydro memve'ele) installed capacity from hydropower is not yet commissioned.
The national grid is currently composed of three independents networks:
The North Interconnected Network (NIN) which has produced in 2018 around 365 GWh of electricity to the northern regions of Cameroon;
The South Interconnected Network (SIN) is the most important of the three networks. With 6023 GWh produced in 2018, representing more than 93% of the national production, the SIN supplies electricity to the southern regions of Cameroon;
The East Network (EN), with a total production of 61 GWh, is an autonomous network which supplies electricity solely to the East region of the country.
Currently, there is no transfer of electricity between the three networks. However, there is a future plan, over the period of 2030–2035, for a project to interconnect the three networks through a National Interconnected Network. At present, each network grid has its own transmission network lines, with different voltage levels, 90 and 110 kV for the NIN, 30 kV for the east network and 90 and 225 kV for the SIN. The National Power Transmission Utility (SONATREL), a state-owned transmission company, is in charge of Cameroon's transmission network. In the context of the future electricity development and the forthcoming National Interconnected Network, it's expected to develop 225 and 400 kV voltage transmission lines, in the context of electricity export in Nigeria, Chad, CAR and Congo, neighboring countries.
In 2018, 6977 GWh of electricity was produced in the country, 78.29% of which from the major electricity operator and the remaining from independent producers . Cameroon's electricity consumption shows that more than three quarter of its total amount is consumed by industry (57.04%) and residential (20.74%) sectors. Figure 4a presents the generation capacity by source while Figure 4b shows the share of final energy consumption in the country in 2018.

The country is endowed with substantial RE potential, such as biomass, hydro, solar, and wind. However, only a very limited percentage of this RE potential is exploited so far. Currently, RE (except hydro) contributes less than 1% to the Cameroon's energy mix and the country aims for a 25% share by 2035 . We present and discuss, at this point, the current status of major renewable energy technologies (RET) for power generation in Cameroon.
Presently, hydropower is the sole RE source on the grid in the country. Hydropower is an attractive source of power for Cameroon with a gross theoretical capability of 294 TWh per year. The technically exploitable capability is around 115 TWh per year, while the economically exploitable capability is approximately 103 TWh per year. This economically exploitable hydro capability is the third largest in Africa, after the Democratic Republic of Congo (419 TWh/yr) and Ethiopia (260 TWh/yr) . There are three large hydropower plants that generate electricity and are located in Edea (286 MW), Song Loulou (384 MW) and Lagdo (72 MW), with the first two located within the River Sanaga Basin. In 2018, hydroelectricity has produced about 5023 GWh in clean electricity representing 71.99% of the total annual production. This actual level of hydroelectric output corresponds to less than 5% of the technically exploitable capability potential of Cameroon. The total hydropower capacity under construction is 751 MW, namely: Bini à Warak (75 MW), Lom Pangar (30 MW), Mekin (15 MW), Memve'ele (211 MW) and Nachtigal (420 MW). Several hydropower projects have been announced, with the planned hydro capacity as follows: Downstream Natchigal (350 MW), Kikot (330 MW), Eweng/Ngodi (1150 MW), Song Mbengué (350 MW), the increase in capacity of the existing Song Loulou hydro plant (+150 MW), Song Dong (270 MW) and upstream Edea (200 MW) . Based on the Least-Cost Electricity Sector Development Plan (ESDP) covering the period 2015–2035, the country has set a long-term plan to further develop hydroelectricity. Table 1 provides the number of Most suitable hydropower sites identified per river/basin, gross theoretical and technically exploitable capability. The technical hydropower potential of the country is estimated at around 12.6 GW, with approximately 7.3 GW concentrated within the River Sanaga basin. Table 2 provides prioritized hydropower sites by projected network, with projected capacity, for which feasibility studies have been carried out.

Due to its geographic location, Cameroon has moderate to high levels of Global Horizontal Irradiation . Figure 5 maps the photovoltaic power potential in the country. Literature in solar energy studies provides limited information and most recent scientific contributions to the subject are outlined in the following articles. Mas'ud et al.  assessed the solar energy readiness in Cameroon by highlighting the irradiation pattern across the country. Abanda  underscored that the mean solar irradiance is roughly 5.8 kWh/m2/day in the northern regions, while it's in the range of 4.0–4.9 kWh/m2/day in the southern regions of the Country. The lack of reliable network of surface observation stations for collecting weather data has led Ayompe and Duffy  to assess the energy output, capacity factor and performance ratio of PV systems using site-specific solar irradiation from long-term satellite-derived datasets accessible in Solar GIS software. From the above studies, the solar energy potential available in the country is massive, despite a poor commitment of the Government of Cameroon (GoC) to boost the solar energy sector. The country is looking forward to implementing a solar PV electrification of some cities under a program named, (Cameroon 2020 Photovoltaic Power Project) PV solar program − Cameroon 2020. Cameroon 2020 Photovoltaic Power Project targets grid-unconnected rural villages as well as grid-connected urban underserved populations. This program is planning to develop 500 MW of installed PV capacity throughout the country for a production of 750 GWh (roughly 1500 MWh/yr for an installed capacity of 1 MW). The first phase of this program is scheduled to install a total PV capacity of 110 MW in three considered networks zones (SIN, NIN and EN) of the country, as shown in Table 3. In the SIN zone, Sangmelima and Meyomessala are presently the only two localities,which are enjoying electricity from their solar PV power plants. In the NIN zone, the GoC has appointed Sinohydro, in accordance with the memorandum of understanding between the two parties, to perform feasibility studies for the design, financing, construction, operation and maintenance of a 20 MW solar power plant in Lagdo.

Cameroon is located in a low wind speed region as outlined by kenfack et al.  and as a result the country is confronted with several challenges in developing wind energy. Nonetheless, the greatest winds are found in the Far North region, around the Logone & Chari division and Lake Chad. This high potential is also observed in highlands in the west region. Yet, the wind energy sector is not well-known and the country has no previous experience in wind power generation. Despite rising interest, wind power remains irrelevant in comparison with hydropower which currently contributes at the level of 742 MW to the national electricity production. Nonetheless, the wind energy outlook is looking bright, thanks to the promotion of an investment-friendly strategy to attract investments in the RE sector. Accordingly, a wind power project in the hilly city of Bamboutos (West region) is in the pipeline with public private partnerships (PPP), within the framework of the Cameroonian government's investment programme. When completed, Bamboutos wind farm will be the country's first commercial-scale PPP wind project, with an installed capacity of 42 MW that would be extended to 80 MW. Once fully operational, the farm will produce approximately 3–6% of the country's electricity generation. As such, this will introduce wind energy contribution to the national energy consumption and mix. Other than the aforementioned project, the far north region of the country, which has a high-quality potential for harnessing and installing Wind Energy Conversion Systems (WECS), is frequently referred to as the next target of the upcoming investment programme planned by the government in the energy sector. Then again, wind resource has not been sufficiently investigated in the country due to the lack of a reliable and straightforward wind atlas. In scientific literature, very few studies have been achieved so far. Tchinda et al.  hypothetically assessed wind energy potential in the far North region of Cameroon. In addition, Tchinda and Kaptouom  analyzed wind speeds and energy distributions in the Adamaoua and North regions of Cameroon. Nfah and Ngundam  identified stakeholders for sustainable growths of renewable energy in Cameroon. Abanda  investigated potentials, benefits and enabling environment of RE sources in Cameroon. Kidmo et al.  performed a statistical analysis of wind speed distribution based on six Weibull Methods for wind power evaluation in the North region. Kidmo et al.  assessed wind energy potential for small scale water pumping and concluded that the potential in the North Region of Cameroon is not fitted for generating electricity. Kidmo et al.  Assessed once more again wind energy potential at hilltops surrounding the city of Maroua in Cameroon for wind-generated electricity. The study established that wind energy at mountain's ridges, hilltops and highlands could be utilized to improve access to cost-effective low carbon electricity. Other studies [27,28] assessed as well wind energy potential in Ngaoundere and Bamenda. Based on published papers, the vast majority these studies were meant to determine or assess wind power potential, simulate WECS output, using various mathematical models. From the comprehensive literature review performed in the present study, no reference is made to installed WECS in the country.
Biomass is a general term that covers biological material derived from living or dead organisms such as plant, trees, wood and agricultural crops and residues, all of which are considered a RE source . Primary biomass resources include woody and herbaceous crops, seeds of oil crops, and residues, while secondary biomass resources, such as sawdust, lops and tops, and animal waste, are processed primary biomass resources. Tertiary biomass resources are post-consumer residues that include animal fats and greases, used vegetable oils, packaging wastes, and construction and demolition debris . As a tropical region, Cameroon is blessed with enormous biomass energy potential evaluated at around 21 million hectares and the country is ranked the 3rd largest biomass potential in sub-Saharan Africa . This ligneous biomass is mostly utilized as a source of energy for rural households such as traditional uses of biomass for cooking. As mentioned earlier, traditional biomass energy consumption accounts for 74.22% of primary energy consumption the country.
Relevant studies on biomass resource in Cameroon are summarized below. Mermoz et al.  assessed biomass in the Cameroon savanna using ALOS PALSAR data. Based on this biomass assessment, a biomass map over Cameroon, was built. Ackom and Minang  assessed the biomass resource potential in Cameroon, mainly, the potential of agricultural and forestry residues. Kamdem et al.  studied the potential production of bioethanol, biomethane and wood pellets from lignocellulosic biomass wastes of the banana plant (Musa spp.) in Cameroon.
In Cameroon, the presence of more than hundreds of thermal springs in the corridor of the active Cameroon Volcanic Line, as well as repeated eruptions of Mount Cameroon, are supportive of geothermal development in the country . Geothermal energy has not been harnessed to date in Cameroon and there is no known energy supply derived from geothermal source. The geothermal energy potential, which has not been completely assessed, is up to now unknown. In the literature, there exists rather very few studies regarding the subject. Keutchafo et al.  reviewed issues of geothermal exploration with a focus on existing barriers hindering the geothermal energy development in Cameroon. By appraising geothermal resources and use in Cameroon, Kana et al.  identified several potential geothermal sites using thermal methods. In that study, the highlight of direct and indirect use of geothermal energy in Cameroon was performed to help raise stakeholders' awareness.
Potentials for wave and tidal energy in Cameroon are concentrated on coastal areas in littoral, South West and South regions. Very few scholars have discussed wave and tidal power in the country. A decade ago, the GoC has hired MRS Power Cameroon, a subsidiary of MRS Holding Ltd to realize feasibility studies on potentials for wave and tidal power in the country . The outcome of these feasibility studies is still awaited and at present, there is no known plan to harness these potentials sources of energy. Furthermore, potentials for tidal current and wave energy are up to now unknown.
Historically, to boost the development of RE, the country has relied on reforms on the electricity sector, led by hydroelectricity largely developed compared to other RE sources such as wind, solar and biomass. Initially, the law n°98/022 of 24 December 1998 governing the electricity sector, which is a general legislation concerning the electricity sector, focused on hydroelectricity development only.Afterwards, the electricity Law 2011/022, governing the electricity sector and promulgated on December 14, 2011, clearly defined RE sources . Key changes under this new legislation included the role of the State in:
ensuring the promotion and development of RE;
establishing the opportunity for the transmission system operator or any local distributor to purchase the surplus of electricity generated from RE sources;
fixing tax benefits for products, goods and services intended for RE exploitation;
Creating an agency responsible for the promotion and development of RE.
This law precisely shapes the legal and institutional supervision for RE promotion, by creating the Department of Renewable energy within the Ministry of Energy and Water Resources.
To cope with the growth of electricity demand, several government plans and programs for energy development have been announced and deliverables are highly expected. The Master Plan for the Development of RE in Cameroon is still to be released. The rural electrification master plan, which focuses as well on RE such as solar energy in the northern regions and hydro energy in the southern regions, is as well to be released.The ESDP up to 2035 is the latest government plan aimed at helping define, for various scenarios of the demand forecasting, using the significant identified hydroelectric sites of the country, optimal sequences of facilities that are the least cost solutions to cope with the demand, or to improve the reliability of the electrical system. Under the ESDP − 2035, short, medium and long terms scenarios are studied and examined, and the forecast of demand includes national needs in addition to electricity exportation to neighboring CAR, Chad, and Nigeria.The country has set ambitious RE targets, under an optimistic long-term scenario, such as achieving more than 5500 MW of hydropower installed capacity by 2035 . In terms of exportations, the optimistic long-term scenario forecasts a demand of an interconnection with Nigeria estimated at 500 MW from 2031 to 2035 and with Chad estimated at 150 MW in 2035.
The existing main Government bodies involved in the promotion and the follow-up of the use of RE, include:
The Ministry of Energy and Water Resources (MINEE), in charge of implementing government action in the RE sector, overseeing energy sector activities, formulating policy, laws, and directives for the promotion of RE;
The Ministry of Economy, Planning, and Regional Development works with MINEE to promote investments in the electricity sector;
The Ministry of Finance provides financial support and different incentives, such as Value Added Tax (VAT) exemptions, to boost the renewable energy sector;
The Ministry of Scientific Research and Innovation is responsible for conducting research in the energy and hydrological fields and, in conjunction with MINEE, is responsible for promoting new energy;
The Ministry of Environment, Protection of Nature and Sustainable Development is in charge of the promotion of sustainable development in the renewable energy sector;
The Rural Electrification Agency is a legal public entity with financial autonomy, focused on promoting and implementing rural electrification in Cameroon and managing the Rural Energy Fund;
The Electricity Sector Regulatory Agency is responsible for policy and regulatory framework and possible funding, regulating the electricity sector as well as setting electricity rates and determining electrical standards. The agency is also in charge of the promotion and the follow-up of the use of the primary sources of energy, in particular renewable;
Electricity Development Corporation (EDC) is a state-owned company that develops the electricity sector, including all hydroelectric projects in the country;
ENEO Cameroun is the main utility company responsible for the distribution of electricity;
SONATREL is the national power transmission utility company, a public administrator and operator of Cameroon's transmission network, a state-owned agency, with the GoC as the sole shareholder.
Independent power producers (IPPs) are private distribution companies.
In 1957, the country has put into service, its first plant, Edea I. Since then, more hydropower plants, namely Edea II (1958), Edea III (1975), Lagdo (1983), Song Loulou (1991) were put into production, and more hydropower projects are on their way nowadays. The country's manpower is hired from electrical, mechanical and civil engineering background and trained in hydroelectricity. The national advanced school of engineering of the University of Yaoundé I (ENSPY), up to now, is training formally in electrical, mechanical and civil engineering. Specific hydroelectricity training is provided to engineers through on-the-job training and short courses at the expense of the national utility company. With the expansion of RET to other sources of energy, such as solar, wind, biomass, more training capability is needed to train manpower and build capacity in RE fields. There are very few academic institutions and scientific research centers dedicated to RE and all of them are state-owned.The department of RE at the national advanced school of engineering in Maroua, offers bachelor degrees courses in six semesters and master degrees courses in four semesters, in the fields of biomass, solar and wind. The national advanced school of public works (ENSTP) Yaoundé, offers master degrees courses in four semesters, in different fields of RE. The national laboratory for energetics research a subsidiary branch of the geologic and mining research institute, is devoted RE research.
RE is currently the leading source of energy in Cameroon for electricity generation and residential sector (traditional uses of biomass for cooking). If properly harnessed, RE could meet an important share of energy demand from commercial and public services, transport, industrial and agricultural sectors. Despite the potential of RE in satisfying energy needs of the country, the success of RE has been hindered by a combination of three main factors, namely, policy and legal, technical and financial issues. The country does not have a precise policy and legal framework for the development and promotion of RE, despite heavy investment trends in Cameroon's hydropower sub-sector.There is limited trained manpower in addition to lack of expertise in RET for the successful dissemination of RE.Major financial issues for the successful implementation of RE projects include the absence of low-cost, long-term financing mechanisms, the lack of stakeholders' awarenessin RE financing mechanisms in addition to unaffordable costs of RET to the poor population.
For the successful development of RE in the country, the GoC, through the Ministry of Energy and Water Resources (MINEE), in charge of implementing government action in the RE sector, needs to formulate proactive and long-term policy, laws, and directives for the promotion of RE. Then, through its agencies and funding bodies, the GoC needs to build training and research networks in RE and equip researchers so to emulate capacity-building initiatives and collaborative research for the rapid dissemination of RET across the country. Furthermore, there is a need to empower stakeholders (scholars, policymakers and entrepreneurs) with the necessary knowledge and skills to disseminate, develop and adapt RE systems to local contexts. Finally, the GoC needs to extend financial support in favor of the dissemination and development of RE through a scheme of incentives, from government-guaranteed purchase prices for RE electricity to competitive mechanisms.
Based on the study, Cameroon has huge RE resources that can be harnessed to generate pollution-free power. The following facts can be summarized regarding RE situation in the country. Biomass, electricity and petroleum are three main sources of energy. In 2018, the total final energy consumption in the country was 7.41 Mtoe, 74.22% of which was from biomass, 18.48% from fossil fuels and 7.30% from electricity. The country's installed electricity generation capacity at present is 1402 MW, 56.15% of which is from hydropower, 43.84% from fossil fuels (17.55% from natural gas and 26.29% from oil) and 0.01% from solar PV. In 2018, 6977 GWh of electricity was produced in the country, 78.29% of which from the major electricity operator (ENEO S.A. Cameroon) and 21.71% from independent producers (GLOBELEQ, ALTAAQA Sinohydro China and AGGREKO). Furthermore, more than three quarters of electricity produced were consumed by industry (57.04%) and residential (20.74%) sectors. Moreover, hydroelectricity, has produced about 5023 GWh in clean electricity representing 71.99% of the total annual production. Mean solar irradiance is approximately 5.8 kWh/m2/day in the northern regions, while it averages 4.5 kWh/m2/day in the southern regions of the Country. Solar power plants programs, which currently target grid-unconnected rural villages, are scheduled for a total installed PV capacity of 110 MW. The greatest winds in Cameroon are found in the Far North region and in highlands in the west region of the Country, but wind power generation is non-existent. Geothermal,tidal current and wave energy potentials are up to now unknown. There is a general legislation in the country concerning the electricity sector, focused mainly on hydroelectricity development. The country is currently building its RE education, research and scholars' capacity.
