Energy for all:
Obstacles and Success Conditions for RE in Developing Countries

In many developing countries there is a much larger potential for renewables like wind and solar energy than in industrialised countries. But there are obstacles that prevent the adoption of such “new” renewables in developing countries. Ulrich Laumanns and Danyel Reiche try to identify the most important obstacles and point to success conditions that can lead to a wider dissemination of “new” renewables in developing countries.

According to the International Energy Agency (IEA), 13.5 % of the world’s total primary energy supply (TPES) is produced by renewable sources of energy. Of this, the main share comes from developing countries. In 2001, developing and transformation countries accounted for 77.5 % of the global renewable energy supply. However, these figures are based on a broad definition of renewable energy (RE). When analysing this data, one finds that developing countries use RE mainly in the form of large hydropower and traditional biomass. Both in Africa and Asia, traditional biomass (basically in the form of charcoal and fuelwood) accounts for over 90 % of energy production from renewable sources of energy. In Africa, the traditional use of biomass for cooking and heating covers around 50 % of the total primary energy supply, rising to around 90 % for some countries of Sub-Saharan Africa.

These figures are impressive, but both traditional biomass and large hydropower produce negative social and ecological externalities which also have to be considered. In the case of traditional biomass, the energy source (in general, this is wood) can often not be classified as renewable, especially in the arid and semi-arid regions of the world. Traditional use of biomass leads to considerable indoor and outdoor pollution and therefore poses a health risk to its users. In the case of large hydropower plants, extensive areas of land often have to be flooded, destroying biodiversity, habitats and forcing the local population to resettle. The so-called “new” renewable energies, such as wind energy, solar energy, geothermal energy, modern biomass, small hydropower and ocean energy, have a much smaller impact on the environment and the social structures and can therefore contribute to a larger degree to a truly sustainable development. However, when looking at the global scale, over 85 % of the energy production from “new” RE takes place in the industrialised countries. At first sight, this is a somewhat paradoxical situation, considering that developing countries have a much larger potential for renewables like wind and solar energy than industrialised countries. There are many obstacles that prevent the adoption of such “new” renewables in developing countries.

Obstacles
Technological
Obstacles in the context of this article can be defined as factors that prevent or make difficult the diffusion of RE technologies. We can differentiate between technological, financial, cognitive, and institutional obstacles. Technological obstacles are such obstacles that are related either to geographic and meteorological conditions which determine the RE potential of a region, or to the RE technology itself. Most developing countries are endowed with a large potential for RE. Also, in contrast to the industrialised countries of Western Europe, most developing countries (with a few exceptions like Rwanda or Bangladesh) have vast areas of unused land which can be used for large-scale RE projects. Thus, this obstacle can be considered as relatively unimportant. On the other hand, the poor quality of some RE technologies which are produced and sold in developing countries is a relatively important obstacle. One example for this are solar home systems (SHS) which are often sold and installed without charge controller or with inadequate batteries. Worldwide, an estimated 10 -20 % of all installed SHS are no longer operational. Experiences with RE systems which do not work contribute to a negative image of the technology among the population and can therefore severely impede its wider diffusion. In addition, RE technologies that have been sold in developing countries are often not compatible with social and cultural norms. For example, the dissemination of solar cookers has often failed because the cookers worked only during daylight hours, whereas households were accustomed to prepare meals after dark and indoors. Finally, there are also obstacles which are inherent to some RE technologies. Wind energy and solar energy, for example, deliver an intermittent supply of energy which varies with the time of day, with weather patterns and with the seasons.

Financial
Financial obstacles are the most important factor hindering the diffusion of RE in developing countries. First of all, many RE technologies are not yet competitive on a cost-basis with conventional forms of energy. In many cases, the advantage of conventional energy is still increased by subsidies. On the other hand, RE systems and their components are often subject to import duties or other taxes. Secondly, the high initial costs for purchasing a RE system are a major obstacle. In most developing countries, only the richest households, if at all, can afford these systems. Credit schemes that could facilitate the purchase of RE technologies are still largely underdeveloped. Of 1.2 million SHS sold world-wide, only around 50,000 have been purchased with a credit.

Cognitive
The cognitive environment for RE in developing countries can also be considered as an obstacle. We can find prejudices against RE on all levels of society, from household, over the private sector, to power utilities and the government. Prejudices on the household level are often reinforced by past experiences with RE systems that have not been installed or maintained properly. Especially in the field of maintenance, there is a widespread lack of information. In all developing countries, one can find the ruins of RE projects that have fallen into disrepair after they had been installed by foreign donors. This is also often due to a lack of skilled personnel in the field of RE technology. In general, awareness on the advantages and characteristics of RE is still rather scarce. Many households do not consider RE when planning their energy provision. Similarly, governments (as much as many international donors) tend to stick to the large-scale, centralised, conventional energy projects they are accustomed to. True, in most developing countries, experiences with RE projects are not very common, and therefore these projects always entail a considerable element of risk and uncertainty. There is also a general lack of reliable and scientific data on the potential of RE in developing countries.

Institutional
Finally, there are also important institutional obstacles for RE in developing countries. Here, we use a broad definition of institutions that encompasses both the legal framework as much as the relevant organisations and markets in the energy sector. For example, markets for RE systems are generally underdeveloped in developing countries. There are only a few market actors which often suffer from a lack of capital. On the other hand, the sale of RE systems in rural areas leads to high transaction costs, due to long travel distances, lack of market information, poor infrastructure, difficult access to customers and the lack of skilled personnel. The existing RE companies often do not have the financial means to meet these transaction costs. Secondly, there are few organisations in the developing world that explicitly promote RE through information dissemination or lobbying, both on the non-governmental and the governmental level. On the other hand, there are often strong interest groups like oil or coal companies which lobby against RE. Thirdly, legal frameworks and energy policies can represent an important obstacle to RE. In developing countries, there is little direct government support for RE, due to the lack of financial resources. In many countries, there is still a state monopoly on power production which means that it is impossible for independent power producers (IPPs) in the field of RE to enter the power market. Other developing countries lack rules for the connection of RE systems to the electric grid. In general, the place of RE in national energy policy is often rather unclear which prevents private companies from investing in RE projects. Furthermore, lengthy and bureaucratic procedures for obtaining a license for power production can prevent investors from setting up RE projects.

Success conditions
Technological
What are the success conditions for the dissemination of RE in developing countries? In principle, a success condition can be defined as the absence of an obstacle. Success conditions can sometimes be created through adequate government policy measures or through social learning processes. As in the case of obstacles, we can also differentiate between technological, financial, cognitive and institutional success conditions. Technological success conditions are generally difficult to create through human intervention. For example, the insolation ratio or the wind regime are factors that cannot be changed through government policy. Nevertheless, the technological potential of renewable energies in developing countries is very high. Another technological success condition is the existence of technical and quality standards for RE technologies that can be fixed either by governments or by the private sector. RE technologies should also be adapted to match the needs and the socio-cultural backgrounds of users (“appropriate technology”). In general, the low population density and dispersed settlement structure of most developing countries are favourable for the supply of electricity through decentralised RE applications (SHS and mini-grids powered by small hydro, biomass or wind), rather than through the extension of the national power grid.

Financial
In regards to financial success conditions, one can mention the existence of credit schemes for RE systems. In the past few years, there have been a number of projects in this field. Many NGOs, like Savordaya in Sri Lanka or Grameen Shakti in Bangladesh, have, with the assistance of foreign donors, set up micro-credit schemes for RE. The Photovoltaic Market Transformation Initiative (PVMTI) of the International Finance Corporation (IFC) has been lending to banks in India, Morocco and Kenya in order to provide financing for loans for solar systems. On the whole, donor financing for RE projects has increased. The World Bank is increasingly willing to support RE. With the creation of the Global Environmental Facility (GEF), new financial resources for RE projects have been made available. RE projects of multilateral and bilateral donors assist in developing RE markets in developing countries. However, much attention has to be paid to the sustainability and replicability of these projects. For example, numerous past projects failed because households got RE systems free of charge and therefore did not feel responsible for maintenance. In the future, the implementation of the Clean Development Mechanism (CDM) could represent a strong incentive for further mobilisation of private capital for RE projects in developing countries. However, there are also national measures that can remove financial obstacles for RE. First, governments should create a “level playing field” through removing subsidies on fossil fuels or at least replacing them with “smart subsidies” which benefit the poor. Secondly, prices of fossil fuels should reflect to a certain degree the negative externalities of these fuels. This can be done through the establishment of CO2-taxes, for example. In the Dominican Republic, revenues from a tax on fossil fuel consumption go to a fund for the promotion of RE. Thirdly, competitiveness of RE should be promoted through abolition of import duties. Tax relief, concessionary grants and subsidies are an important success condition in those developing countries that can afford these measures. For example, India’s “accelerated depreciation” policy (together with government subsidies) has led to a rapid increase of wind turbine installations and the creation of the largest wind power industry in a developing country. The same holds true for feed-in tariffs, like the ones that have been recently introduced in Brazil.

Cognitive
Cognitive success conditions are: a population that is aware and informed about the benefits and risks of RE technology, a private sector that has access to adequate information on the market potential for RE as much as to skilled RE technicians, and a government that is open towards the utilisation of RE in the context of its energy policy. These success conditions can be created through information campaigns, and through lobbying by NGOs and RE business associations. Organisations that provide consultancy and advice on RE play an important role. Of equal importance are international projects that transfer technology and know-how from industrialised to developed countries. Other cognitive success conditions are the integration of RE technologies into the national education system (both at school and higher education levels) and the promotion of scientific studies which measure the potential for RE (like wind atlases). Recently, the United Nations Environment Programme (UNEP) has set up the Solar and Wind Energy Resource Assessment (SWERA) project in order to measure RE potential in a number of developing countries.

Institutional
There are a few important institutional success conditions for RE in developing countries. Above all, RE has to be integrated into energy policies. An important incentive can be the establishment of RE targets, as in the case of China (until 2010, 5 % of additional capacity from RE), India (until 2012, 10 % of additional capacity from RE), Pakistan (until 2015, 10 % of electricity production from RE), Tunisia (25 % of energy production from RE by 2010), and some other developing countries. Secondly, energy markets should be opened to provide IPPs with the possibility to invest in RE power projects. Today, only around 25 developing countries allow power production by IPPs. There also have to be clear legal guidelines for the production and feed-in of electricity from RE sources, in order to create security for private sector investment. For example, Thailand has introduced a net metering law, allowing RE producers to feed excess power into the grid. Whenever possible, RE projects should be given preference over conventional energy projects. Especially in the context of rural electrification, RE can play a major role. Countries like Argentina, China, India, Morocco, Philippines, South Africa and Sri Lanka emphasize RE in their rural electrification programmes. The existence of organisations like NGOs, RE businesses, or government agencies, that promote RE constitutes an important success condition. Examples are the India Renewable Energy Development Agency (IREDA) and the Indian Ministry of Non-Conventional Energy Sources (MNES), the Centre for the Development of Renewable Energies (CDER) in Morocco, the Chinese Renewable Energy Industries Association (CREIA), or the Egyptian New and Renewable Energy Authority (NREA). Diffusion of RE also depends on functioning markets.

In developing countries, there is a high and rising demand for electricity. Two billion people word-wide are still waiting to be electrified. However, RE companies in developing countries often lack the capacity to satisfy this demand. In order to facilitate RE market development, government or donor support to RE companies (by means of loans, training, or business advice) represents a very important success condition. For example, the African Rural Energy Enterprise Development (AREED) Programme of UNEP provides financial and technical support to RE companies. In the past, assistance for RE in developing countries has been focused on setting up demonstration projects. For the future, efforts should concentrate on addressing obstacles and creating success conditions.

Primer aparato de aire acondicionado solar en España 5 - Septiembre - 2007

Archivado en: #E.E.R.R., +Solar Termica — enerxia @ 8:25 am

SunTechnics y ClimateWell firman un acuerdo para lanzar en España el primer aparato de aire acondicionado solar

La máquina de climatización, que también es capaz de producir calefacción y agua caliente sanitaria, está acoplada a placas solares térmicas y “puede contribuir a cambiar el mundo”, según el Foro Mundial Económico.

 

SunTechnics, suministrador alemán de sistemas solares, tanto térmicos como fotovoltaicos, ha sellado un acuerdo de colaboración con ClimateWell, empresa hispano-sueca especializada en la fabricación y distribución de máquinas de climatización solar térmica capaces de producir tanto frío como calor. Mediante este acuerdo, SunTechnics incluye en su oferta la máquina de absorción ClimateWell 10, primer sistema de frío solar adecuado para uso doméstico, aunque la empresa subraya que también es ampliable para usos industriales.

En vísperas de las vacaciones estivales, ClimateWell confirmó haber iniciado las obras de construcción de una fábrica para producir en serie, por primera vez, el ClimateWell 10. La empresa prevé arrancar las líneas de producción en 2008. Según el Foro Mundial Económico, esta máquina puede “contribuir a cambiar el mundo”, puesto que la máxima radiación solar coincide con la mayor demanda de frío, aliviando así la demanda eléctrica (y la emisión de CO2) característica de los sistemas de climatización convencional. El sistema, además, también suministra calefacción en invierno y agua caliente sanitaria todo el año.

El acuerdo con SunTechnics “implica la realización de instalaciones en toda España para que haya referencias cerca de los clientes”, según Per Olofsson, Director General de ClimateWell. “De esta manera, SunTechnics y ClimateWell, han creado la primera infraestructura profesional para frío solar que cubre toda España” (en la foto, instalación de SunTechnichs en Cabo de Gata, Almería).

Para Alberto Madina, delegado comercial de ClimateWell en España, se eligió SunTechnics para este acuerdo porque “tiene una posición privilegiada, ya que cuenta con una red de delegaciones en toda España, capacidad propia de instalaciones llave-en-mano, una gama de productos muy adecuada y de alta calidad y un equipo profesional con una gran visión de crecimiento”.

Como paso previo al acuerdo, SunTechnics ha instalado un sistema de refrigeración solar en la sede de ClimateWell, un chalet situado en la madrileña localidad de Fuencarral. Mediante el uso del ClimateWell 10, se consigue la climatización de la planta principal del chalet, de aproximadamente unos 220 metros cuadrados. La energía para el accionamiento de la máquina generadora de frío es captada por dieciocho colectores solares SunTechnics STK 1800 integrados en el jardín del chalet, donde ocupan una superficie de aproximadamente 45 metros cuadrados.

El Gobierno abre al fin las puertas a la eólica marina 5 - Septiembre - 2007

Archivado en: #E.E.R.R., +Eolica, -+Hidráulica y del Mar — enerxia @ 8:23 am

El Consejo de Ministros ha aprobado el Real Decretadministrativas necesarias para construir instalaciones de generación de electricidad que se encuentren en zonas marinas. o que regula el procedimiento para la obtención de las autorizaciones y concesiones

El Real Decreto aprobado en Julio establece la realización de un “estudio estratégico ambiental del litoral español”. Los ministerios de Industria y Medio Ambiente realizarán conjuntamente dicho estudio con el objeto de determinar las zonas del dominio público marítimo terrestre que reúnen condiciones favorables para la instalación de parques eólicos marinos. El estudio establecerá zonas aptas y zonas de exclusión para estos usos. Una vez aprobado el estudio, las solicitudes de reserva de zona sólo podrán presentarse para las zonas aptas.

El Real Decreto, que pretende recoger “toda la normativa que resulta de aplicación e integrarla en un solo procedimiento administrativo”, fija un límite mínimo de 50 MW de potencia para autorizar instalaciones eólicas que pretendan ubicarse en el mar. Sólo con carácter extraordinario, para un proyecto o proyectos particulares, se habilita al Ministro de Industria para modificar, hasta en un 20% al alza o a la baja, el límite mínimo de 50 MW para permitir una instalación o la superficie máxima en función de la densidad de potencia. La competencia para la tramitación de estas instalaciones será exclusivamente estatal.

Mil megavatios en 2010
En relación con las instalaciones eólicas ubicadas en el mar, todavía no hay ninguna en nuestro país. Actualmente, según el ministerio de Medio Ambiente, “existen diversos proyectos eólicos marinos ambiciosos en una fase inicial de diseño e ingeniería básica, en las costas de Cádiz, Huelva, Castellón y en el Delta del Ebro”, por lo que “cabría pensar que en el horizonte del año 2010, estas instalaciones podrían aportar en torno a los 1.000 MW (actualmente se encuentran en el ministerio de Medio Ambiente, pendientes de tramitación ambiental, 31 proyectos que suponen 2.800 MW)”. El objetivo de 1000 MW en 2010, supondría unas emisiones evitadas de un millón y medio de toneladas de dióxido de carbono al año (MtCO2/año).

La minihidráulica crece en Europa por debajo de lo previsto 5 - Septiembre - 2007

Archivado en: #General — enerxia @ 8:19 am

Con más de 11.600 MW instalados en el año 2005, el sector de la minihidráulica (esto es, con una potencia inferior a 10 MW) forma parte integrante del sistema de producción de electricidad de la Unión Europea. Sin embargo, este sector debe hacer frente a una problemática doble y en apariencia contradictoria: conciliar los imperativos de productividad al tiempo que mantener una buena calidad ecológica de las aguas, según pone de manifiesto el barómetro EurObserv’ER.

 

“Nuestra última encuesta en agencias de energía, administradores de las redes y especialistas de los países respectivos nos ha obligado a reevaluar nuestras estimaciones en cuanto a la potencia europea de pequeñas instalaciones hidráulicas a 11.534,6 MW en 2004″, señala el consorcio en un comunicado.

Para 2005 se estimaba que la potencia del parque europeo fuera de 11.643,5 MW, es decir 108,9 MW adicionales. Italia con 2.592 MW y Francia con 2.040 MW son los dos países con mejores equipamientos. Junto a España, Alemania, Austria y Suecia, estos seis países representan el 84,3 % de la potencia instalada en la Unión Europea.

La Unión Europea posee la primera industria mundial de energía hidráulica de pequeñas instalaciones. EurObserv’ER indica que, en parte, debe esta supremacía económica a la importancia del mercado europeo, que siempre ha sido más exigente en cuanto a la productividad o las repercusiones medioambientales. “Este saber hacer ha permitido a Europa exportar sus productos a países asiáticos o latinoamericanos con un gran potencial”.

La Asociación Europea de Pequeñas Instalaciones Hidráulicas (ESHA) calcula sus cifras de venta entre 150 y 180 millones de euros. El sector emplea 20.000 personas y en Europa hay unos 50 fabricantes de turbinas hidráulicas. Algunos de ellos son empresas filiales de multinacionales como Alstom Power Hydro, VA Tech/Andritz y Voith Siemens.

Perspectivas para 2010
La situación del mercado de pequeñas instalaciones hidráulicas sigue confrontada entre aquellos países que refuerzan su contribución al desarrollo (España, Italia, Francia) y países que, al contrario, quieren abandonar sus sistemas de apoyo (Austria y Suecia).

A este respecto, EurObserv´ER indica que “si bien aún es incierto que los países miembros alcanzarán sus objetivos, teniendo en cuenta el ritmo de crecimiento observado en el 2005, parece probable que el nombre de instalaciones aumente en los próximos años. Nuestras previsiones, que están basadas en un crecimiento anual del 2 %, conducen a la Unión Europea a unos 12.855 MW en 2010,
en comparación con los 14.000 MW previstos por el Libro Blanco”.

ESHA prevé que no se obtendrá el objetivo europeo hasta el año 2015, con una potencia europea en 2010 de 14.040 MW (1.040 MW en los 10 nuevos países miembros). Una evolución de este tipo necesita mientras tanto que se reduzcan las barreras administrativas y medioambientales, añade la asociación

La UPV desarrolla un novedoso sistema de climatización con geotérmica 5 - Septiembre - 2007

Archivado en: #E.E.R.R., +Geotermica — enerxia @ 8:18 am

La Universidad Politécnica de Valencia ha desarrollado una innovadora tecnología de climatización geotérmica, que además de usar la temperatura permanente del subsuelo para refrigerar los edificios, permite un 40% de ahorro energético respecto a los sistemas tradicionales y disminuye el riesgo de contaminación por legionela.

 

La principal ventaja demostrada por un grupo de investigadores de esta universidad en la instalación GeoCool, una planta piloto desarrollada en el marco de un proyecto subvencionado por la Comisión Europea, es la capacidad de su sistema para ahorrar energía respecto a los sistemas existentes de aire acondicionado, informa Efe.

El sistema de climatización geotérmica de edificios, muy extendido en los países nórdicos, ha sido adaptado a las características del clima y la edificación mediterránea por un equipo de investigadores de la Universidad Politécnica de Valencia (UPV) dirigidos por el profesor Javier Urchueguía. En el consorcio, liderado por la UPV, también participan otras universidades europeas y empresas como la española Ciatesa.

La tecnología ha sido ensayada en una planta piloto construida en el edificio de la Escuela Técnica Superior de Ingenieros Industriales de la UPV, única en el mundo ya que incluye tanto el sistema tradicional de climatización como el geotérmico junto a un sofisticado sistema de monitorización que permitió a los investigadores un exhaustivo estudio de todos los parámetros que influyen en el proceso.

Ambos sistemas fueron usados alternativamente durante 18 meses, después de los cuales quedó demostrado que la climatización basada en el intercambio térmico con el suelo consigue un ahorro energético de más del 40% respecto al sistema tradicional y, por tanto, también disminuye en esa misma proporción las emisiones indirectas de CO2 a la atmósfera.

Según explicó a Efe el profesor Pedro Fernández de Córdoba, a diferencia de los sistemas de climatización tradicionales, que se basan en el intercambio de calor del edificio con el aire que lo rodea, la climatización geotérmica “cede (o extrae) ese calor con el subsuelo del edificio, que tiene una temperatura más moderada y constante que el aire (unos 20 grados en Valencia)”. Por tanto, para refrigerar una estancia en verano, el sistema tradicional elimina el calor excedente al aire, mientras que el caso geotérmico, el calor excedente se trasmite al subsuelo.

Otra ventaja es que la climatización geotérmica elimina buena parte del ruido asociado a los aparatos de climatización convencionales. Además, al no requerir torres de refrigeración para su funcionamiento, el sistema geotérmico disminuye los problemas asociados a ellas, como el riesgo de legionela.

Urchueguía y Fernández de Córdoba han creado la empresa Energesis Ingeniería para la instalación de esa tecnología.

La compañía Transportes Ceferino Martínez ha construida una planta que produce 16.000 litros diarios de este biocarburante para abastecer a su flota de camiones. El biocarburante se utiliza puro.

3 de septiembre de 2007

La planta construida por Tranportes Ceferino Martínez en Girona produce 16.000 litros diarios de biodiésel, el cual se utiliza puro, sin mezclar con gasóleo, en la amplia flota de camiones propios que dispone la compañía. En total, la planta tiene una capacidad anual de 5.000 toneladas año.

Según la compañía transportista, el fabricar su propio biodiésel permite controlar estrechamente su buena calidad, “apostando por una energía renovable y económicamente rentable, y permitiendo una mejora de los márgenes comerciales al poder minimizar el encarecimiento del gasóleo de los últimos meses”.

La tecnología utilizada ha sido proporcionada por la empresa sueca Ageratec y su socio español AutoProducción de BioDiesel, S.L.. Ésta incluye los últimos avances y soluciones técnicas -algunas en proceso de patente- en la producción de biodiésel. Con esta fábrica el grupo sueco se introduce en España, y se suma a las más de 50 instalaciones que el grupo tiene en muy diversos países de todos los continentes.
