Besides creating environmental pollution, these stoves create health problems for a housewife and are based on biomass, which is not easily accessible and tedious to collect. Nevertheless every rural household aspires to have a cooking technology and fuel which gives a blue flame and is very user-friendly [1]. Nimbkar Agricultural Research Institute (NARI), Phaltan, MAharashtra, India have developed a simple ethanol stove which can run on 50% ethanol/water mixture. The power of stove is 2.5 kW(thermal). Shortly they will test 10 of these units in rural homes nearby. <_created>2004-11-13 17:21:28<_owner>2<_group>9<_origin>8view1700htmlhttp://www.wbcsd.ch/plugins/DocSearch/details.asp?type=DocDet&ObjectId=MTE2NzMThis article was prepared by Health & Medicine Week editors from staff and other reports.

Also, despite continued efforts, the energy sector has not grown fast enough to keep pace with the demands for energy services by consuming sectors. To ensure efficient and prudent energy use, trends in energy utilization and supply and resultant environmental impacts need to be monitored and assessed regularly. Addressing this very need, TERI annually publishes the TEDDY (TERI Energy Data Directory and Yearbook)---a storehouse of data and developments compiled chronologically, featuring relevant energy- and environment-related issues for the year. TEDDY is meant not only for business conglomerates and entrepreneurs but also for general readers as it provides an overview of the energy sector and compiles statistics, maps, and data related to energy demand and supply, agriculture, forests, transport, and renewable energy sources and technologies. The electronic version of the publication, TEDDY Online+, provides updated time series and cross-sectional data on energy subjects. This year’s edition -- TEDDY 2003/04 -- continues the tradition. Not only is it informative but user-friendly as well. Spread over 486 pages, the directory is divided into four sections: Energy supply, Energy demand, Forests, Local and global environment. Highlights of the analysis of the year’s energy scenario in India are as follows. Marked shortage of imported coking and non-coking coal due to increased demand from China was observed. There were active pursuits of equity oils in countries, such as Iran, Iraq, Libya, Myanmar, and Syria. The power supply position improved marginally; however, there were supply and peaking deficits to the tune of 7.1% and 11.2%. The plant load factor of thermal power stations in the country has improved during the Ninth Plan. About 4800 megawatts of power-generating capacity based on renewable energy sources has been installed. This is about 4.5% of the installed capacity in the country. There exists a potential to generate 3500 megawatts of bagasse-based power from 453 sugar mills in India. <_created>2005-03-08 05:52:02<_owner>2<_group>9<_origin>8view2250pdfhttp://www.ehponline.org/members/2006/9084/9084.pdfFrederica P.

The Papillon was developed from the SK 14 and its performance is 50 % higher. Two different target groups got involved in the project: low budget families and families with a steady income. There were different payment conditions for these two groups. Nearly all families acquired a gas bottle, a gas cooker and a thermos basket together with the SC. The objective of the evaluation was to find out the frequency of use of the solar cookers (SC), the use of other fuel, the economies made by using the SC. Finally we wanted to identify the factors that contribute to the use of the SC´s and the factors that inhibit it. Important factors are the family size, the family income, its living place, cooking times, number of meals cooked per day, the motivation of the cook. Key words: SC Bamako and Papillon, frequency of use, cooking process, facilitating and inhibiting factors. 1. INTRODUCTION In 2001 I moved to Burkina Faso with my family. In view of the deforestation and the erosion of soil (1) apparent around the city of Bobo Dioulasso in the southwest of the country I became interested in the activities of local solar energy organizations. These were above all scarce. Only a protestant organization had started a program for the promotion of solar cookers (SC). In spring 2002 I myself acquired a SC of the Bamako type (SK 14) and one year later a Papillon. Both cookers are in daily use ever since – weather permitting – in our 10 head household, thus saving about 50 % of gas. In the following years I got involved in the promotion of SC in Bobo Dioulasso aswell as in Gorom Gorom in the north of the country. Apart from the introduction of SCs I wanted to find out how effectively SCs work and which conditions contribute to or inhibit their use. My study is a contribution along these lines. By questioning users and monitors as well as by personal observations, three minor projects conducted with SCs Bamako and Papillon in Bobo Dioulasso in the years 2001-2005 have been evaluated. (1) See: Paul Krämer: Die Holzknappheit im Sahel und das Potential der Solarkocher, Gaia 12 (2003) S. 212-214 2. THE DIFFERENT TYPES OF SOLAR COOKERS For Project 1 A Bamako for Low Budget Families in Bobo Dioulasso a fix focus cooker called Bamako was used. This SC is based on a model that had been developed by Dr. Dieter Seifert and was used by the GTZ (Gesellschaft für technische Zusammenarbeit) in Mali in the 70´s and became very widespread afterwards. The mirror is 1.4 m in diameter and the focal distance is 0.26m. The reflector consists of aluminium segments that concentrate the sun beams on the bottom of the potthat is placed in the middle of the SC. With best conditions 6.27 l of water boil within an hour. In the two other projects the newly developed cooker Papillon (butterfly) was introduced. The Papillon has been developed in 1997 by Dipl. Ing. J. Dessel in collaboration with Prof. Bernd Hafner and the Solar Institute in Jülich/Germany. Its construction was based on the experiences and suggestions of the users of the Bamako. Characteristics: - The performance of the Papillon is 50 % higher than that of the Bamako. With best conditions 10.75 l of water boil within an hour. - The cook can approach the pot directly, so that cooking is easier. - The cook isn´t blinded when working behind the mirrors. - The reflector panels are not situated under the pot. Thus they get dirty less quickly - The Papillon has wheels and its wings can be folded up so it can be transported by only one person. Solar cooker Papillon The disadvantage consists in the more complicated technical production. If the dimensions aren´t correct, the cooker doesn´t perform at its best. At this moment the Papillon is produced only in Burkina Faso only in Ouagadougou, the capital. Another disadvantage is lack of stability. The rough winds of the North make it turn over if not placed in a calm corner. However most of the clients prefer the Papillon because of its higher performance. 3. PROJECTS 3.1. A Bamako for 10 low budget families in Bobo Dioulasso From 2001 to 2004 the Protestant development organization ACCEDES realized a project that benefited 70 families. Each family obtained the following equipment: a Bamako SC, a bottle of gas (12.5 kg), a gas cooker and a thermos basket for retained heat cooking for 135,000 FCFA. The payment was done by instalments. As the down payment and the instalments were relatively high only families with a steady income could afford the SC this way. Thus in 2003 10 cookers plus gas and thermos baskets got an additional subsidy to make it possible for low-budget families to buy a SC, too. Now the total amount to be paid was: Subsidies: 70 % Price: 50,000 FCFA (78 €) Payment conditions: low down payment and low instalments (5000 FCFA) 3.2. Papillons for the women of the UFD in Ouagadougou The Union des Femmes pour le developpement (UFD) is a parent organization that covers about 30 women organizations with in total more than 1000 members in four different quarters of the capital and four surrounding villages. From 2004 onward the UFD has been realizing a project starting with 35 SCs. The SCs are sold on credit together with a thermos basket and a big black pot, size 6 (18 l). Subsidies: none Price of all: 133,500 FCFA (200 €) Payment conditions: high down payment (12 500 F CFA), low instalments (4 500 FCFA) The instalments equal the amount that can be saved in fuel if the SC is frequently used. These repayments are used to buy further SCs. In addition they pay for the monitoring and the administration costs of the project. In March and April 2004 the Papillons were delivered to the households and the monitor visited the different families 2 or 3 times to train the buyer and/or the housemaid in cooking with the SC. Furthermore she had to collect the monthly instalments and inspect the SC. 3.3. Papillons for the Protestants in Bobo Dioulasso In the spring of 2005 a small project with 16 SCs was executed in BD by Tle Nafa (in Dioula language: advantages of the sun). Tle Nafa is a local association cooperating with ACCEDES with the objective of promoting SCs. If they wanted to, the women could buy a thermos basket and a gas bottle with integrated cooker. Subsidies: 20 % Price of the SC: 80,000 FCFA (125 €) Payment conditions: Low down payment and low instalments (5000 FCFA) The buyers of the SCs were in part members of the staff of ACCEDES or familiar with the organization. The delivery of the cookers and the rest of the equipment, the training and supervision and the collection of the monthly payments were the task of an experienced female monitor. 4. RESULTS OF THE INTERVIEWS The users of the SCs were visited and interviewed at home and the SCs were checked as well by the author and the monitor. Unfortunately we could only visit the women of the Bamako project in the dry season. The other women were interviewed in the rainy season where cooking with the SC often is impossible. Here some of the results are presented in tables. 4.0. IN WHICH CONDITION ARE THE SOLAR COOKERS? Projekt 1: 9 of the 10 Bamakos are working well. The lock of the cookers had been damaged for 5 weeks. The blacksmith has already been informed by the monitor. Projekt 2: 12 of the 15 Papillons in Ouaga are in a good condition. 3 SCs are damaged, two are still working, one not.

CONCLUSIONS 5.1. How often are the SC´s being used? In Bobo Dioulasso the Bamako is frequently used by the women with low incomes. Eight of ten women declare to use it daily – weather permitting. Also the majority of the Papillon owners in Bobo say they use it daily (73 %). In Ouagadougou only 46 % of the buyers use it daily. (Table 4.1.) These results are according to the information the women give about the fuel savings. In Bobo the women save more than in Ouaga. In general the amount of fuel being saved permits the conclusion that only a part of the women use the cooker to the full extent. This is confirmed by the use of the SC during the raining season. In Bobo 55 % of the families continue to cook with it, in Ouaga, however, it´s only 38 %. 5.2. Which fuel is being used? One household uses mostly wood, the next nearly exclusively charcoal and the other mostly gas. However most of the households combine in different ways wood, charcoal and gas with the SC. (Table 4.2.) Families who possess a gas cooker and a gas bottle do not automatically use only gas and sunshine as it was intended by the projects in Bobo. Only one family in Bobo and one in Ouaga use exclusively gas and the SC. The reason is probably the lower price of wood and charcoal compared to gas. 5.3. Time factor Most of the housewives and maids in BF go to the market in the morning to buy the ingredients for the warm meal at lunch time. Afterwards cooking begins. When the meal has to be ready at 12.00 or 12. 30 p.m. often – dependant on the size of the family - only a part of it can be cooked on the SC. When cooking is done twice a day the preparations for dinner begin often late in the afternoon. Then it´s too late for the SC. Nearly all households need warm water for washing. For that the SC is an excellent solution. A part of the water can be kept warm in the thermos basket. 5.4. Family size and number of meals cooked per day define the SC´s usefulness In a lot of families in BF cooking is done only once a day. In the evening the meal is just warmed up. This is the case also in a lot of our households (Table 4.5.) In addition there are some relatively large families. (Table 4.4.). For large families (10 persons and more) when cooking is done only once a day the Papillon and even more the Bamako reach the limits of their performance capacity. Especially when rice or mush of corn or millet is prepared. The pots sizes 5 (15 l) and 6 (18 l) that are used for large amounts still fit in the holder of the SC but the heat necessary for a successful meal can only be achieved on very clear days. 5.5. All local meals can be prepared All local meals can be prepared on the Papillon and the Bamako. Important is the heating capacity of the SC and that the pot can be opened during the cooking procedure. But the preparation of the mush of corn or millet, one of the principle meals in BF, is problematic. Only a small majority of the women cooking with the Papillon also use it for the preparation of the mush. The Bamako is used for it by only one woman. (Table 4. 6) All the women with Bamako complain about the insufficient heat and the uncomfortable position. A few women with the Papillon also complain about the insufficient heat (7 of 24 women) and the uncomfortable position (6 of 24 women). However some women heat the water needed for the mush first on the Papillon before transferring it on the wood fire in order to save money. 5.6. There must be enough space and sunshine Most people who buy the SC have their own courtyard and enough space. Families living in crowded courtyards may lack the space and the neighbours may be suspicious. Sometimes there is not enough sunshine in the courtyard. 5.7. The motivation of the female cook is what makes all the difference. Women who have opted for the SC are supposed to make frequent use of it. This is not always true for maids. In Project 1 the buyer of the SC and the cook are always the same. Most of the SCs are used frequently (Table 4.1) In the Papillon project in Ouaga housemaids are cooking in 73 % of the families, in Bobo it´s 46 %. It depends also on the motivation of the housemaid whether the SC is used at its best. A secretary in OU (7 persons/ 2 cooking procedures a day) says: My housemaid wants to finish her job quickly. She finds the SC too slow. During the week she prepares mainly rice with the SC. The motivation of the cook is also determined by the income situation of the family. In Ouagadougou some families were rather rich. Probably the motivation to save fuel is higher in middle and lower income families. Another factor is perhaps that the Bobo people were well informed about the SC. Two women who inscribed for a Papillon had even already acquired a Bamako two years ago. Now they wanted the new model. 5.8. Solar cooking requires a readiness for learning and flexibility As mentioned before cooking with the SC takes more time. This means that the cook has to put on the water for the mush or the rice before she goes to the market. It also means that she finishes later. That she may have to transfer the pot from the SC to the gas or the cook stove. Especially on sunny days during the rainy season one has to be flexible. Sometimes the sky is clear at 9 or 10 a.m. but first clouds appear at 11 a.m. The lifting of the heavy pot is not everybody’s cup of tea. Those who declare to go on cooking during the rainy season probably possess a high motivation for the use of the SC. In Ouaga these are 5 of 13 households, in Bobo 6 of 10. Intensive training of the buyer and the cook is crucial for a good use of the SC. When maids are cooking, they, too, must be trained. 5.9. Payment conditions We found out that nearly all buyers of the Papillon have a steady income. Surely this is one reason for the correct repayment of the credit in both cities. Many of the buyers have even made a higher down payment than necessary and pay back faster. This means that the (slightly subsidised) acquisition of a SC on credit is a suitable model for middle class households. In the first project, A Bamako for low income families, 10 women decided to buy a SC. It took some of them, however, months to make the down payment and the instalments were often not paid in time. It´s easy to claim that by using the SC money is saved every day. But when there is little money anyway and the situation is aggravated for example by sickness or high corn prices it gets difficult to make payments on time. Furthermore the savings of fuel are less than calculated. The repayment schedule of the UFD in Ouaga was based on savings of 150 F CFA per sunny day (250 days a year). This would mean monthly savings of 4 687 F CFA in the dry season. (8 months) The results of the interviews, however, show that the savings are often lower – of course partly due to the insufficient use of the SC. In view of these facts we conclude that the price of the SC and the monthly instalments must be lowered, in order to reach lower budget families that form the majority of the urban population of Burkina Faso. 5.10 . After sale service is highly recommended The correct handling of the SC and of the thermos basket must be learned. The new cooking habits have to be encouraged and practised. Then the women will easily get used to them. In case of a cooker defect the repair service must be reached easily and make the cooker work properly. <_created>2006-09-05 10:12:18<_owner>1961<_group>1<_origin>1view2670pdfhttp://www.she-inc.org/docs/80.pdfby Darwin O'Ryan Curtis, Boiling Point Magazine No 52, December 2006http://www.she-inc.org/docs/80.pdfSolar cooking technology has been around for decades, but has been poorly understood and has not been widely disseminated.

WISDOM (woodfuel integrated supply/demand overview mapping) is a spatially explicit method, based on geographic information system (GIS) technology, which ranks a set of spatial units according to a group of indicators, in order to identify woodfuel priority areas or woodfuel hot spots. A comprehensive analysis was conducted, integrating full coverage national data on land cover classes, land cover change maps (1993–2000), geo-referenced population censuses (1990 and 2000), and a meticulous review of the international literature and Mexican case studies. Following a spatial multi-criteria analysis, 2395 counties (out of a country total of 2424 in year 2000) were ranked based on the number, density and annual growth rate of FW users; the percentage of households that use FW; the resilience of FW consumption, and the magnitude and likely trends of FW forest resources. The WISDOM analysis allowed the identification of 304 high priority counties (HPC), which showed a spatially aggregated pattern into 16 clusters.

We estimated that 1:3TgCO2 y1 are released to the atmosphere by non-renewable FW burning, a value that represents less than 1% of Mexican total annual CO2 emissions in 2002. The results of the analysis show that WISDOM is a useful tool for both focusing resources to critical areas where action is more needed and to obtain more accurate estimates of the impacts associated to FW use.<_created>2008-01-16 17:03:03<_owner>2296<_group>1<_origin>1view2720Adrian Ghilardi, Gabriela Guerrero, Omar MaseraGhilardi2007.pdfA WISDOM analysis was conducted in Mexico in order to: (1) identify fuelwood (FW) hot spots in terms of residential FW use and availability of FW resources for the year 2000, and (2) estimate net CO2 emissions from the non-renewable use of FW.
