A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy transition in MENA countries has been developed and applied to the country case of Algeria. It is designed to support the strategy development and governance of the energy transition and to serve as a guide for decision makers.
The analysis shows that Algeria has already taken first steps towards a renewable energy transition. According to the MENA phase model, Algeria can be classified as entering the "Take-Off Renewables" phase. Nevertheless, fossil fuels still play a dominant role in the Algerian energy sector and in the economy as a whole. To support the renewables take-off, strong support is therefore needed at all levels. Only then can the necessary framework conditions be created to encourage participation and to attract investment from the private sector. To this end, a long-term energy strategy should to be developed that takes into account the renewable energy potential to support an efficient transformation of the Algerian energy supply and enables a smooth transition.
Especially in the arid areas of the Middle East and North Africa (MENA), water availability plays an important role in the expansion planning of industrial-scale solar power plants. Although power plants may account for only a very small portion of local water demand, competition for water with other sectors is expected to increase when water resources are insufficient for meeting local needs. This can lead to conflicts between different users (such as communities, farmers, tourism, businesses and utilities). Despite the increasing attention on the water-energy nexus, comprehensive studies analysing the interdependencies and potential conflicts between energy and water at the local level are absent.
To examine the linkages between water resources and energy technologies at the local level, this case study was selected because Morocco is one of the countries most affected by water scarcity and, at the same time, it is also one of the most promising countries in North Africa for the development of renewable energies and offers excellent conditions for solar and wind power plants. Nevertheless, the country's electricity system is still largely based on conventional energy sources, and the country is more than 95% dependent on energy imports. To strengthen the country's energy security and reduce the financial burden associated with energy imports, Morocco is pursuing an ambitious renewable energy expansion strategy: by 2020, around 42% of the national electricity demand should be met by renewable energies. In view of Morocco's ambitious plans, it is particularly important to identify the potential conflicts and synergies resulting from the expansion of renewable energies in relation to the water sector.
The energy sector today accounts for about 10% to 15% of global freshwater withdrawal. Most water in the energy sector is used for generating electricity, especially for cooling processes in thermal power plants. At the same time the demand for electricity is expected to increase significantly due to population growth and economic development in emerging and developing economies. Growing demand is also driven by electrification strategies pursued by industrialized countries to decarbonize their economies. With the global demand for electricity expected to increase significantly in the coming decades also the water demand in the power sector is expected to rise. However, due to the on-going global energy transition, the future structure of the power supply - and hence future water demand for power generation - is subject to high levels of uncertainty because the volume of water required for electricity generation varies significantly depending on both the generation technology and cooling system. In light of these challenges the objective of this analysis is to provide more systematic and robust answers in terms of the impacts of different decarbonization strategies in the electricity sector on water demand at global and regional level. The focus is on operational water use for electricity generation.
By applying a phase model for the renewables-based energy transition in the MENA countries to Israel, the study provides a guiding vision to support the strategy development and steering of the energy transition process.
The transition towards a renewable-based energy system can reduce import dependencies and increase the energy security in Israel.
Key issues that need to be tackled in order to advance the energy transition in Israel are the expansion of flexibility options, discussion on the long-term role of natural gas, increasing participation and awareness, and exploring the future role of power-to-X in the energy system.
A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy transition in MENA countries has been developed and applied to the country case of Iraq. It is designed to support the strategy development and governance of the energy transition and to serve as a guide for decision makers.
The transition towards renewable energies is still at a very early stage in Iraq. Despite the drop in renewable technology costs over the last decade and the increasing deployment of renewables in the MENA region, the pathway towards renewable energies seems to be challenging for Iraq. This is attributable to the country's political instability and the dominant economic role played by the fossil fuel sector. The most pressing concern for Iraq's electricity sector is the need to secure a constant electricity supply. At operational level, Iraq's electricity infrastructure requires significant investment to rebuilt, retro-fit and expand its overall capacity and to improve efficiencies.
Yet, the need to rebuild the energy system after the war and the subsequent violent conflicts could offer an opportunity for a transition towards renewables that would benefit Iraq in the short term and also provide a long-term economic development perspective. To take advantage of this opportunity, Iraq needs to improve the framework conditions for renewable energies and raise awareness about the benefits it offers. Renewable energy regulations need to be introduced, market development supported, a realistic timeframe for the transition process established and an appropriate and reliable legal framework developed. The results of the analysis along the transition phase model towards 100% renewables are intended to stimulate and support the discussion about Iraq's future energy system by providing an overarching guiding vision for the energy transition and the development of appropriate policy strategies.
A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy transition in MENA countries has been developed and applied to the country case of Egypt. It is designed to support the strategy development and governance of the energy transition and to serve as a guide for decision makers.
Egypt, with its abundant solar and wind energy potential, has excellent preconditions to embark on the pathway towards a 100% renewable energy system. The country has successfully taken its first steps in this direction by attracting international finance and implementing several large-scale solar and wind projects. Yet, while Egypt has made significant progress, increased efforts are still required if the country aims to proceed towards a fully renewables-based system. The stronger system integration of renewable energies requires, for example, an alignment of regulations for the electricity, mobility and heat sectors. In this context, Egypt would be well advised to develop and implement an overall strategy for the energy transition that includes not only electricity generation but all sectors.
By placing a stronger focus on renewable energy, also to decarbonise the industrial sector, Egypt, as Africa's second most industrialised country, could seize the opportunity for economic development within a decarbonising global economy. The results of the analysis along the transition phase model towards 100% renewable energy are intended to stimulate and support the discussion on Egypt's future energy system by providing an overarching guiding vision for the energy transition and the development of appropriate policies.
Water availability plays an important role in the expansion planning of utility-scale solar power plants, especially in the arid regions of the Middle East and North Africa. Although these power plants usually account for only a small fraction of local water demand, competition for water resources between communities, farmers, companies, and power suppliers is already emerging and is likely to intensify in future. Despite this, to date there has been a lack of comprehensive studies analyzing interdependencies and potential conflicts between energy and water at local level. This study addresses this research gap and examines the linkages between water resources and energy technologies at local level based on a case study conducted in Ouarzazate, Morocco, where one of the largest solar power complexes in the world was recently completed. To better understand the challenges faced by the region in light of increased water demand and diminishing water supply, a mixed-method research design was applied to integrate the knowledge of local stakeholders through a series of workshops. In a first step, regional socio-economic water demand scenarios were developed and, in a second step, water saving measures to avoid critical development pathways were systematically evaluated using a participatory multi-criteria evaluation approach. The results are a set of water demand scenarios for the region and a preferential ranking of water saving measures that could be drawn upon to support decision-making relating to energy and water development in the region.
Water and energy are two pivotal areas for future sustainable development, with complex linkages existing between the two sectors. These linkages require special attention in the context of the energy transition. Against this background, this paper analyses the role of water availability in the development of solar thermal and photovoltaic power plants for the case of the Draa Valley in southern Morocco. Located in a semi-arid to arid mountainous area, the Drâa Valley faces high water stress - a situation expected to worsen due to climate change. At the same time, the region has one of the greatest potentials for solar energy in the world. To examine whether limited water availability could accelerate or delay the implementation of solar thermal and photovoltaic power plants, this paper compares regional water availability and demand in the Draa Valley for different scenarios, paying particular attention to potential socio-economic development pathways. The Water Evaluation and Planning System software is applied to allocate the water resources in the study region. The water supply is modelled under the Representative Concentration Pathway 8.5 climate scenario, while the water demand for the Drâa Valley is modelled for a combination of three socio-economic and two energy scenarios. The climate scenario describes a significant decrease in water availability by 2050, while the socio-economic and energy scenarios show an increase in water demand. The results demonstrate that during a sequence of dry years the reservoirs water availability is reduced and shortages in water supply can result in high levels of unmet demand. If this situation occurs, oasis farming, water for drinking and energy production could compete directly with each other for water resources. The energy scenarios indicate that the use of dry cooling technologies in concentrated solar power and photovoltaic hybrid systems could be one option for reducing competition for the scarce water resources in the region. However, given that energy generation accounts for only a small share of the regional water demand, the results also suggest that socio-economic demand reduction, especially in the agricultural sector, for example by reducing the cultivated area, will most likely become necessary.
A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy (RE) transition in the Middle East and North Africa (MENA) countries has been developed and applied to the country case of Tunisia. It is designed to support the strategy development and governance of the energy transition and to serve as a guide for decision makers.
The analysis shows that Tunisia has already taken important steps towards a RE transition. According to the MENA phase model, Tunisia can be classified as being in the "Take-Off Renewables" phase. Nevertheless, natural gas still plays the dominant role in Tunisia's highly subsidised electricity generation. In addition to the elevated political uncertainty, there are numerous structural, political, social, and economic challenges within the energy sector that hinder progress in the transition to REs.
Strong support at all levels is needed to promote the breakthrough of RE. This includes more detailed long-term planning and improving the regulatory framework, as well as reducing offtaker risks to improve the bankability of RE projects in order to attract private investment. Furthermore, institutional buy-in needs to be increased and the engagement of key non-state stakeholders must be strengthened.
In light of the growing domestic energy demand and with the on-going global decarbonisation efforts in favour of sustainable fuels, Tunisia would be well advised to embark on a sustainable energy path sooner rather than later to seize economic opportunities that can arise from RE development.
A clear understanding of socio-technical interdependencies and a structured vision are prerequisites for fostering and steering a transition to a fully renewables-based energy system. To facilitate such understanding, a phase model for the renewable energy (RE) transition in the Middle East and North Africa (MENA) countries has been developed and applied to the country case of Lebanon. It is designed to support the strategy development and governance of the energy transition and to serve as a guide for decision makers.
Lebanon's energy transition towards REs stands at a very early stage of the first transformation phase. Although abundant solar and wind energy potential does exist, the pathway towards a 100% renewables energy seems very challenging for Lebanon, as a consequence of highly unstable political conditions. The most pressing concern for Lebanon's electricity sector is combating the country's fiscal imbalance, while providing secure and reliable electricity supply. At the operational level, Lebanon's grid network requires significant investments to rebuild, retrofit, and expand the overall capacity and energy efficiency improvements.
The need to strengthen the energy system after the political turmoil of the civil war is likely to offer several long-term opportunities, such as developing the economy, reducing environmental pollution, and increasing the energy security. In order to move forward into the first phase, Lebanon needs to improve the framework conditions for REs and implement its visions. It needs to support the market development in a realistic timeframe, where structural reforms represent the highest priority.
The results of the analysis along the transition phase model towards 100% renewables energy are intended to stimulate and support the discussion on Lebanon's future energy system by providing an overarching guiding vision for the energy transition and the development of appropriate policies.
