TOWARDS ENERGY EFFICIENCY: CASE OF MOROCCO

A major challenge for humanity in the twenty-first century is to combine energy with respect for the environment. During the Rio Earth Summit (2012) the issue of sustainable development was clearly demonstrated. One of the major battles this century for the planet's survival is to include energy efficiency as an international policy priority in order to achieve a significant decrease in greenhouse gas emissions. In this paper, we have presented the current state and outlook of energy efficiency in the transport, residential and industrial sectors, as well as its policy for each sector in Morocco. New strategies implemented by the government for sustainable development were reviewed and discussed. Through these strategies, the shift to energy efficiency is at the forefront of national policy implications for energy security and a low-carbon economy.


Introduction
World demand for energy is increasing through population increase, as well as through industrialization and the urban development process (Energy, Photovoltaic, System, Iea, & Publishes, 2018;IEA, 2017). This underscores the value of such issues such as sustainability, supply security, alternative forms of energy and the strengthening of the national energy source potential. The latest evolutions and trends, the sharp swells in demand, warfare, and diplomatic concerns all contribute to the perception of energy issues as a serious issue on the world's agenda. In some references, energy efficiency is among the energy resources. Rather than starting to build a new plant with high-cost investments, the energy efficiency of the plant can contribute towards meeting the growing need for energy. In addition, it could deliver significant environmental and other operational rewards in terms of cost and greenhouse gas emissions improvements.
To meet the high demand for electricity which is increased by about 7%., Morocco intends to invest more than 15 billion euros over the next 10 years to increase installed capacity by around 6,750 MW.
The most important measure in Morocco's energy balance is the total consumption of 28.25 billion kWh of electricity per year. This represents an average of 790 kWh per capita. However, Morocco could supply itself completely with self-produced energy. Whereas, the total production of all electricity generation facilities is 29 billion kWh. In addition to pure consumption, production, imports, and exports have an important contribution to make other energy sources such as natural gas or crude oil are used as well. A large amount of electricity used contributes to high levels of CO2 emissions in Morocco. On the other hand, energy intensity aimed to be decreased by enhancing efficiency measures and promoting clean energy technologies (Iea, 2019).
Energy efficiency in the transport sector in Morocco deserves attention from the point of view of energy security and the environment, as the sector depends almost exclusively on a fuel-oil which represented the lion's share of the energy imported.

The transport is the key factor of global sustainable economic development as reported issued in International Transport Forum (ITF) Transport Outlook 2013 based relatively cost-efficient as well as reliably networked transport. However, the transport sector is responsible for air pollution, because it causes large greenhouse gases emissions into the atmosphere, which eventually leads to climate change. Therefore, the main task for policy makers struggling to elaborate on strategic transport plans is to a trade-off between the pros and cons of transport developments.
Such strategic planning for the long term is only feasible if there is factual and reliable information on transport development which is based on statistics, analysis, and research.
The industrial sector represents between 30 and 70% of the world's total energy use and is responsible for a significant proportion of global greenhouse gas emissions (Broberg Viklund & Johansson, 2014; T. T. Xu, 2011).
Improving energy efficiency in the industrial sector is one of the major pillars of this strategy. Further, intends to require energy audits in the industry sector to achieve the targeted energy efficiency ratio (from 12 to 15%) by 2020. The obligation of energy audits in industries is clearly stated in the 12th article of the Energy Efficiency Law 47-09 (Law, n.d.).
To energy efficiency policies in the area of transport , residential, and industry there are certain theories which should be considered such as the theory of rational choice, the theory of reasoned action, the theory of planned action, the theory of social learning, the theory of cognitive dissonance, and social theory, etc. Further, various energy efficiency surveys in industrials, residentials, transports sectors are exploring energy consumption patterns. The methodology employed in these studies is to interview holds of different sectors such as households to identify their electricity use patterns and understanding the values that are driving their behaviours. The use of questionnaires to outline the efforts of both consumers and government bodies on energy concerns (Dianshu, Sovacool, & Vu, 2010;Whitmarsh & O'Neill, 2010). Also, there are studies suggesting that may be more effective economic concerns rather than environmental concerns (Gyamfi & Krumdieck, 2011).
There are a lot of energy reduction policies pursued in many countries. Increasing the acquaintance, offering feedback, incentives, disincentives, and social influences are among the examples of behaviour change measures used in policy-making. These actions are outlined in the following:  Public information: Positive information interventions enhance the level of awareness and knowledge of the energy concerns of the individuals. To disseminate the information that there are several ways among the people: workshops, flyers/posters, mass-media campaigns, home-based audits, energy labelling and modelling (Abrahamse, Steg, Vlek, & Rothengatter, 2005;Robinson, 2009).  Feedback: To keep people informed of their use, it is possible to provide feedback under different forms and at different frequencies. The most common form of feedback for electricity users is utility bills. (Abrahamse et al., 2005;Nachreiner, Mack, Matthies, & Tampe-Mai, 2015).  Incentives / benefits: Both monetary and non-monetary rewards can motivate people to save energy.
These can result from a reduction in energy use or a more successful change in energy efficiency behaviour (Abrahamse & Steg, 2009;Bresciani, Colorni, Lia, Luè, & Nocerino, 2016;McMakin & Malone, 2002).  Target setting / Investment: This is an alternative approach to motivate people to become involved to save energy. An engagement is an oral or written commitment or pledge of change, and it may be linked to an  (6) objective. This guarantee can be a bond for oneself, in which case it can be used to activate either of the following a personnal norm such a high moral obligation to conserve the energy (Abrahamse & Steg, 2009;Martiskainen, n.d.).  Social influences: These kinds of measures of attitude and behaviour are taken from a larger group of people than the previous ones. Group or organization leading people to achieve a common purpose or even sometimes to challenge each other between themselves to get the greatest possible reduction in their energy use. (Abrahamse & Steg, 2009).
Through the years, researches have been carried out to foster policies and to study the impact of implementing strategies on energy reduction and efficiency. The full range of literature and the common policy alternatives derived from the literature are not restricted to those outlined above. In recent literature, it has been highlighted again that a more effective combination of awareness and education with cost-effective measures is more efficient (Lindén, Carlsson-Kanyama, & Eriksson, 2006) and shows that the economic rewards of energy saving as a result of these activities increase consumer awareness levels. Through the different studies, the common conclusion was that holds of different sectors were responding to these economic measures and that they needed to be used effectively to achieve energy efficiency (Allcott, 2011).

Energy intensity of Morocco
In 2017 The TFC is widely driven by the three sectors -transport, residential and industrial -as well as representing over four-fifths of the total final consumption, but also exhibiting high expansion and growth rates. Despite the energy consumption of Morocco increases along with the economic development of the country, however, as compared to a decade ago, energy intensity (TFC / GDP) fell by 9% (see Figure 1). In terms of energy intensity, which is measured by the ratio of TFC per unit of real gross domestic product as settled for purchasing power parity (PPP), it was 60.5 tonnes of oil equivalents (toe) per million dollars of GDP in 2017.

Energy consumption
The transport sector used 5.8 Mtoe in 2017, representing the highest proportion of Moroccan TFC. Energy use in transport has increased by 58% since 2007 and increased more than four times since 1990 (AZEROUAL et al., 2018;Iea, 2019). Petroleum is the most dominant transport fuel in Morocco's rapidly expanding transport sector, while electricity and biofuels have no role to play.

Fig. 3.Transport energy demand by transport mode and fuels, 2017
Source: IEA (2019 forthcoming), World Energy Balances 2019 preliminary edition www.iea.org/statistics/ Highway transport uses 99% of transport energy, with about 86% of this consumption being from diesel and the remaining from gasoline ( see Figure 3). Transport use in Morocco is mainly driven by freight, passenger cars, cabs, and commercial vans. The constant growth in the overall vehicle fleet reflects Morocco's GDP per capita growth of the country's government, and its aspiration to be a regional pole of the automotive industry.

Various policy targets in transport sector
Measures for energy efficiency in the transport sector have been enacted in various strategies (Iea, 2019;Law, n.d.):  The strategy of the Ministry of Equipment, Transport, Logistics and Water (METLW) for 2017-2021 highlights the importance of sustainability, economic and socially efficient transport systems, which are more reliable, more energy efficient to use more user-friendly.  Strategy for developing the competitiveness of Moroccan logistics is intended to decrease the use of energy by 2030, as well as to foster multimodal transportation and the transition to more efficient modes of transport. Also, several measures have already been taken in place in road transport to reduce greenhouse gas emissions in a significant way (METLW,2018). Moreover, developing a national roadmap for sustainable mobility supported by the German Development Institutions (GIZ).

Energy consumption
The residential sector has consumed 4.0 Mtoe in 2017, which represents a 26% increase compared to 2007. The oil, essentially liquefied petroleum gas (LPG), is the main fuel used by 63% of total consumption in the industry, followed by electricity (23%), and biofuels (14%) (Figure 4.7) (AZEROUAL et al., 2018;Haas, 1997;Lebied, Sick, Choulli, & El Bouardi, 2018). During the period 2007-2017, the use of LPG increased by 50% and electricity by 67%, which replaced the solid biofuels that had been the primary source of heating and cooking. In the residential sector, the uptake of traditional types of biomass-wood and charcoal dropped to 43% over the same period. This is reflective of the efforts made by the Moroccan government to develop alternatives to biomass, in order to avoid deforestation as well as the health problems that are related to their use. Morocco's cooking represents roughly two thirds of the residential sector's total energy use. Other main residential energy needs include water heating, refrigeration, lighting and electrical appliances. Heating and cooling of space account for a very small part of total household energy consumption, such as shown in Figure 4. 265 Meanwhile, residential energy use rose by 27% over the period 2006 to 16 in parallel with demographic growth, the energy use by building sector slightly declined over the period, reflecting the turnover of the building fleet with new and more energy efficient dwellings (see Figure 5).

Fig. 5. Residential consumption and energy intensity
Source: IEA (2018a), World Energy Balances, 2018, www.iea.org/statistics/ The consumption of oil is still representing about 63% of residential energy use in Morocco. Morocco has reached the universal access to electricity on the part of its rural population, which promotes an increasing and widespread use of electricity as well as the use of modern appliances, especially to meet cooling and other needs.

Various policy targets in residential sector
The main laws that govern this sector of residential are (Iea, 2019;Law, n.d.): Law No. 47-09 on the energy efficiency of 17 November 2011:  Requiring the company to provide information on power capacity and the use of energy, as well as to carry out mandatory energy audits if the use exceeds 500 toe (oil equivalent) tonnes per year.  Implementation of the standard NM 14.2.300 on the labeling of household appliances and electrical products. The appliances that require mandatory labeling are cooling appliances (refrigerators, freezers and air conditioners), cooking appliances (electric ovens), cleaning appliances (dishwashers, washing machines and dryers).  Increasing the public awareness initiatives to promote the transition to more efficient appliances as well as to provide the benefits of using appliances with higher efficiency standards to the public.  Implementation of summer time, by adopting the GMT+1 time zone during the summer months (May-July, September-October) to improve the use of daylight. On the other hand, there are plans to:  Renovation of the city's public lighting installations.  Extension of the public lighting network to the entire urban territory.  Reduce the impact of energy costs on the municipal budget (consumption and maintenance).  Establish a preventive and corrective maintenance regime to ensure that equipment is maintained in optimal technical and economic conditions. the implementation of the Law No. 47-09 on the energy efficiency is estimated in the side of labeling to save a net of 8% of national electricity consumed within 15 to 20 years. Further, the implementation of energy efficiency law will reduce the emissions of greenhouse gaze. 266 5. Energie effiency in the industrial sector

Energy consumption
The major energy sources used in Morocco are oil and electricity (see Figure 6). Fuel oil or other petroleum products are by far the most significant energy source, representing 68% of overall use in 2017, while electricity is the second most important source, 3% biofuels and waste as well as 2% of natural gas. The TFCs in the industry reached 3.8 Mtoe in 2017, up from the peak reached during -13 (AZEROUAL et al., 2018Iea, 2019). The use of oil decreased from 2013 onwards as subsidies for fossil fuels were abolished and subsequently increased again in 2017.   267 The production of chemicals involves the processing of phosphate into fertilizers and other chemicals. The remaining industrial sectors, which include the processing industries, such as pulp and paper, food products (i.e sugar production) and tobacco processing, textile, and leather production ( Figure 6).
Despite the fact that industrial energy use rose by 41% in 2004-2015, its intensity declined during the same period by 13%. A decrease in energy use intensity per unit of GDP is mainly due to more energy efficient industrial processes or to structural changes in the national industry.

Various policy targets in commercial sector
The main laws that govern this sector of commercial are (Iea, 2019;Law, n.d.): Law No. 47-09 on energy efficiency in the industrial sector:  Requiring companies to declare their installed capacity and energy use, as well as to carry out mandatory energy audits, if the use exceeded 1500 tons of oil equivalent (toe) per year.  Training sessions to assist companies of large scale business in the process of optimization and streamline their use.  Shifting the energy use of Morocco's industrial sector from the super peak tariff in order to benefit from a significantly lower rate in hours of low demand. For instance, the companies of high energy-intensive companies, including the steel industries, have been joining this program of energy efficiency to decrease their energy bills.  Morocco's industrial sector is very sensitive to peak electricity prices. The super peak tariff for industries prompts them to shift their energy use out of the peak periods on a voluntary basis, in order to benefit from a significantly lower rate in hours of low demand. Further, several energy-intensive companies, including the steel industries, have been joining this program of energy efficiency to decrease their energy bills.  Encouragement of the companies to become more energy efficient by setting limits on air pollutant emissions. Further, improvements in energy efficiency, meanwhile, reduce Greenhouse gases emissions.

Conclusions
The high levels of energy demand resulting from socio-economic development are the key concerns of the 21st century world. In fact, policy makers around the world are pursuing suitable innovative strategies to reach sustainable development, in which enhancing the life-quality and protecting the environment are high priorities.
The national energy strategy in Morocco, focusing on improving energy efficiency, is surely the most important national concern. It makes Morocco one of the most ambitious countries in the world in terms of promoting sustainable development. Consequently, Morocco has been the centre of significant investments in energy efficiency, mainly as a result of the high availability of energy resources.
In this paper, we reported the energy efficiency in Morocco in sectors of transport, residential, and industrial and emphasized that the swift transition to energy efficiency constitutes the main challenge for the Moroccan government. Consequently, we have briefly reported the energy policy for different sector and their achievements in Morocco.
