Introduction

    The global demand for energy and more specifically clean energy is growing rapidly. There is a universal need for efficient technologies that will contribute to the sustainable development of the host countries and communities by providing

    employment, improving quality of life and protecting the environment. This energy solution must pass obligatory by the development of new clean, nonpolluting and non dangerous sources of energy for the environment and must necessarily guarantee

    sustainability on a human scale contrary to the current energy solutions.

Renewable energies are without danger to health and without pollution for the

    environment. Increasing the global share of renewable energy would not only bring environmental benefits, but also enhance overall energy security by diversifying energy supply.

    The renewable energies are clean, are used where they are and their decentralized character is well appropriate at the scattered state of the areas with low density of population. They can contribute to the environment protection and be regarded as a future alternative to conventional energies, particularly in the rural world which constitutes a potential market because of the prohibitive cost of the routing by cable of electricity.

    The international community recognizes the vital importance of renewable energies, beside the energy effectiveness and of the conservation of energy, not only to fight against the health and the environment degradation and to ensure a sustainable

    development in conformity with the international objectives relating to the climate, but also to contribute to the innovation as well as the regional and national development.

The renewable sources of energy are converted into useful energy while:

    ? contributing to the reduction of the greenhouse gas emissions ;

    ? providing opportunities for poverty eradication;

    ? limiting the risks and the pollution of the planet;

    ? decreasing our energy dependence while not depriving of access to energy

    the present and future generations;

    ? enhancing energy security;

    ? reinforcing the local economy by the development of small and medium-sized

    companies;

    ? creating export opportunities of electricity;

    The actual total cost of renewable energy remains high compared to fossil fuels, although it continues to fall. Increasing the global share of renewable energy would not only bring environmental benefits, but also enhance overall energy security by diversifying energy supply.

    Algeria has not only the world’s most extensive gas reserves, but also huge renewable energy resources especially solar and wind power. Algeria plans to increase the share of renewable energy in its total supply to 5 per cent by 2010. To achieve this, Algeria has developed its own national strategy for renewable energies. The objective is to ensure the changing of hydrocarbons and a sustainable development without danger to health and without pollution for the environment.

    Why a law on Renewable Energies and the Sustainable Development in Algeria today? Exposed reasons

    The search for an energy solution sustainable and compatible with the environment is posted today among the priorities in the programs of the United Nations for the development and the environment.

    This energy solution must pass obligatorily by the development of new clean, non-polluting and non dangerous sources of energy for the environment and must necessarily guarantee durability on a human scale contrary to the current energy solutions.

    Today more than ever, the development remains completely tributary no matter what one says and on a very large scale of energy: it was always thus and it will be still more in the future, even if current technology ensures a better effectiveness, excellent outputs and a much better reliability.

    The question of energy, climatic changes and the sustainable development takes a large importance in our programs of development in Algeria.

    Promoting renewable energies is now one of the major pillars of the Algerian energy and environment policy. Every single renewable energy chain has been closely studied, taking into account its development potential, the type of energy needs and our own resources (hydrocarbons, solar and wind energy).

    Algeria has set up a national programme for the promotion of renewable energy sources in the frame of its sustainable energy development plan for 2020. The first target is to increase electricity production by the renewable energies to 5% of the total production by 2010.

Three principal reasons plead in favour of renewable energies development in

    Algeria:

    ? they constitute a solution economically viable to provide energy services to the

    rural isolated populations in particular in the Great South areas, ? they allow a sustainable development because of their inexhaustible character,

    and of their limited impact on the environment and contribute to the

    safeguarding of our fossil resources,

    ? the monetisation of these energy resources can have only positive

    repercussions as regards of regional balance and creation of jobs.

Algeria has decidedly chosen sustainable development as its energy strategy, the

    legal and regulatory framework adopted during the past years underscores our strong

    commitment. I can quote between others:

    ? The law relative to the electricity and to the public distribution of gas,

    promulgated in February 2002, liberalized the sector of electricity by opening

    to competition the production and the marketing of electricity.

This law which takes in account the protection of the environment envisages the

    integration of renewable energies in the energy mix of the country. It opened in other

    hand side, the way to the promulgation of other inciting measures in favour of

    renewable energies. Advantageous premiums are granted to the producers of

    electricity produced from renewable sources. The purpose of the promulgation of this

    law is the implementation of a national policy of control of the energy based on the

    rational use of energy, the development of renewable energies and the reduction of

    the negative effects of the energy system on the environment.

    ? A decree, on diversification of electricity production costs was enacted the

    25

    th of March 2004.

The incentive premiums of this decree shall attract private investors to implement

    integrated solar combined cycle plants in Algeria.

    ? Another law, the law on renewable energies within the framework of the

    sustainable development promulgated in August 2004, makes possible to

    institute economic incentives founded on the environmental benefit of the

    electricity produced from renewable sources.

This law will constitute a basis for lawful instruments aiming at the encouragement of

    the development of renewable energies in their environmental and ecological

    dimensions.

The national power consumption will grow obviously, like that of all the countries in

    the process of development and certainly much more strongly than it is thought,

    taking account of the most recent forecasts on our economic growth and especially industrial which are specified at the horizon.

    Restraint measures of greenhouse effect gases resulting mainly from combustion of fossil fuels were decided since the Rio Summit of Earth in 1992 and were followed by other rigorous measures decided in Kyoto in 1997 straightforwardly to impose on the international community the penetration of Renewable Energies in a progressive and interdependent way.

    In accordance with the national energy policy and pursuant to the present decree on Renewable Energies, the Commission of regulation of electricity and gas will adopt each year the quotas of production of electricity starting from Renewable Energies for each producer of electricity.

    The producers not respecting the provisions fixed by the commission will have to discharge penalty.

    The penalty will be equivalent to 250% of the electricity price worked out by the operator of the market.

    In compensation of the electricity production over cost produced from Renewable Energies, it is allotted to the producers of electricity from RE a subsidy for each kWh yielded to the network.

    The electricity produced from installations using thermal solar, will profit from a subsidy of 200% of the price, by kWh of electricity, by taking account of a minimal contribution of solar energy of 30% of the whole of the primary energies.

    For the installations whose contribution of fossil energies exceeds 70 %, the subsidy will be reduced by 25% per fossil section of 5% of energy which could not exceed 90%.

    The electricity produced from installations of waste valorisation, will profit from a subsidy of 120% of the price, by kWh of electricity produced. That produced from the wind or hydraulic power, will profit from a subsidy of 100% of the price per kWh That produced from radiant solar energy will profit from a subsidy of 300% per kWh of electricity. The electricity produced from cogeneration installations, will profit from a subsidy per kWh of 100% by taking account of a thermal energy production usable of 20% of the whole of the primary energies used.

    Algeria also owns an institution able to promote the use of the renewable energy sources within the framework of activities of the diversification of our energy source. To develop renewable energies projects, Algeria created the company New Energy Algeria (NEAL).

New Energy Algeria

Neal is a company created between Sonatrach, Sonelgaz and private company (SIM)

    in July 2002 having as object the :

    ? promotion and the development of new and renewable energies;

    ? identification and the realization of projects related to these energies;

    ? definition, development and the implementation of development strategies,

    ? organisation of industrial and commertcial activities.

The objectives which were assigned to it were, in particular the:

    - use of new and renewable energies,

    - contribution to the production of electricity from solar and wind,

    - marketing of the electricity produced this way as well on the local

    market as to export,

    - promotion of photovoltaic, in particular in the south of the country,

    - search of partners for the investment and the exploitation of new and

    renewable energies,

    - constitution of a research pole for the solar with the research and/or

    formation centers.

Development potential of renewable energy

Beyond its hydrocarbon resources, Algeria has a high potential of renewable energy

    which it has the ambition to develop with foreign partners. The development of these

    potential, in particular huge reserves of solar energy would have several positive

    consequences for Algeria, its partners and the world community in general.

    The promotion of the electricity produced starting from the renewable energy sources

    is in the forefront of the priorities of Algeria for reasons of energy supply

    diversification, for reasons of environmental protection and for reasons related to

    economic and social cohesion.

? Wind Energy

The kinetic energy of wind is a promising source of renewable energy with significant

    potential in Algeria. However, the energy that can be captured by wind turbines is

    highly dependent on the local average wind speed.

    With regard to Algeria, the wind resource varies much from a place to another. This is

    mainly due to a very diversified topography and climate. A preliminary study of the

    seasonal and annual evolution mean velocity of the wind (figure1), made possible to

    make a first identification of the windy areas of Algeria.

    Figure 1 “Estimation of the wind resources”

    This representation of speed in the form of chart has two objectives: first is to identify

    the wide areas with good promises of exploitation of the wind power. Second is to

    highlight the relative variation of the resources through Algeria.

    Knowing the problems encountered for the electric power transport in the far areas as

    well as its high cost. It would be interesting to consider the application of conversion

    systems of the wind power for isolated areas having an appreciable wind potential.

    The South-west region shows all the characteristics of sites candidate to the

    exploitation of this energy.

? Solar energy

    Fortunately, its solar power capacity is one of the largest on earth. More than

    2.000.000 Km

    22 receives yearly a sunshine exposure equivalent to 2500 KWh/m.

    The sunshine duration on the whole national territory exceeds the 3000 hours

    annually (table1) and even reaches 3900 hours on the high plateaus and the Sahara.

    Regions Sahara Coastal High

    Region Plateaus

    Table 1: Solar potential in Algeria

There are several ongoing electrification projects in rural areas using solar energy as a

    supplement to classical power grid. Photovoltaic systems are also successfully used

    for water pumping for the development of steppe areas. Another program for Saharan

    areas electrification using photovoltaic systems is carried out for the benefit of remote

    southern populations. These programs of solar energy supply give to the population of far villages a first access to information and communication since provided electricity makes possible to ensure various services. The exploitation of this solar potential enables us to complete our program for rural electrification; today 95% of the country is covered by the domestic grid. Remote areas, far away from the power grid can only benefit from electricity supplied by an adequate use of renewable energy. As the major solar field in Algeria is located in hydrocarbon regions endowed with natural gas, our strategic goal is to create a mixed solar-gas synergy, taking advantage of our abundant natural gas and solar resources. Coupled with renewable energies the natural gas is an energy resource of choice for the development of Algeria and offers the type itself of structuring vector for our integration to the world economy. Independently of the units of solar energy intended to feed the remote centres, projects of renewable energies connected to the national grid are in course of development. Algeria strategy consists in carrying out a synergy between the Solar one and the natural gas thanks to hybrid solar gas projects by profiting from the Algerian natural gas endowment and to the permanent sun shining of the South of the country.

    A first gas-solar hybrid project, of large capacity, is under development. The project will enhance the solar energy share in the global energy balance, increased renewable electricity connected to the national distribution grid. The NEAL Company is in charge of the development of this project.

    The Hassi R' mel gas-solar hybrid power station will be built for 130 MW of gas and 25 2. The project will be established on a plate of ground of MW of thermal solar energy with the parabola system of the giant mirrors on a surface 130 ha. It will lay out of 250 solar collectors 150 meters length and 5 meters in of approximately 180 000 mdiameter each one. The solar field is 90 ha. The production which will result from this power station will come from approximately 130 MW produced from gas turbines and 25 MW produced from the solar field.

    The Algeria sees ideal opportunities of combining Algeria’s richest fossil energy source the natural gas with Algeria’s most abundant renewable energy

    source the sun by integrating concentrating solar power into natural gas combined

    cycles.

    The development of solar energy could save significant quantities of hydrocarbons and particularly of natural gas, which could be exported towards Europe and the United States. The positive implications are double: Firstly, the reduction of burned fossil fuels will reduce the greenhouse gas emissions, while contributing to improve the energy supply of our partners.

Conclusion

There is no doubt that the available energies won’t disappear soon, nevertheless the

    era of abundance and cheap energy will not last long. We will have to consider alternate sources of energy. It is clear that renewable energy is linked to environmental issues. This is the reason why the quest for unlimited and clean renewable energies should become the priority.

Conscious of the need to face its environmental problems and anxious to take part in

    the fight against the climatic change, Algeria has the concern of the sustainable

    development and implements from her side, the strategies and measures in this way.

    Algeria has definitely decided to pursue an active role within the global mobilisation for

    environmental protection and the promotion of sustainable development.

Algeria is endowed with significant resources of renewable energies and particularily

    solar and wind energies, for which the country has several sites among the most

    promising in world.

The Algerian energy strategy major concerns and priorities have always been the

    important link between energy management, environment and sustainable

    development.
