GTZ is now GIZ

The Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) was formed on the 1st of January 2011. It brings together the long-standing expertise of the Deutscher Entwicklungsdienst (DED) gGmbH (German Development Service), the Deutsche Gesellschaft für Technische Zusammenarbeit (GTZ) GmbH (German Technical Cooperation) and Inwent – Capacity Building International, Germany.

New design tool – make your own custom rocket stove!

Rocket Stove.org and Prakti Design Lab with financial support from HERA, have developed a new automated design tool that allows users to build a customized institutional rocket stove. After you enter all of the relevant information, the tool will produce a custom set of Rocket stove plans. Stove options include: Brick Stove without Chimney, Rectangular Metal Stove without Chimney, Circular Metal Stove without Chimney, and Rectangular Stove with Chimney. If one already owns a cooking pot, and would like to build a suitable stove, one needs to specify pot and material dimensions carefully and enter the values into the tool. The tool then generates a custom set of Rocket stove drawings for the selected pot. The tool can be used online, directly on the homepage, or as an Excel sheet if there is no reliable access to the Internet. A manual, designed by Peter Scott, helps to build the Institutional Rocket Stove. For more information about the tool see the @HEDON box at the bottom of GIZ news.

GIZ-PSDA receives PCIA special achievement award

Award Kenya Annagwe PCIA 2011- web image.png

At its 5th Biennial Partnership Forum in Lima, the Partnership for Clean Indoor Air (PCIA) awarded the stove component of GIZ’s Promotion of Private Sector Development in Agriculture programme (PSDA) in Kenya. Component manager Anna Ingwe received the special award for improving technology design and performance. PCIA especially appreciated and recognized the dedication of the project to rigorous field testing resulting in improved stove design and clean, efficient cooking technologies. The panel was also impressed by the commercialization of stoves activities, making the product efficient, affordable and easily available. Over 1 million stoves at household level have been disseminated between Jan 2006 – December 2010. Anna Ingwe stated: “This Award is not only a motivator, but also a reason to focus on our future plans with renewed determination. Our ambition is to reach 30% of Kenyan households with efficient stoves.” The PCIA Forum was hosted by GIZ Peru.

Agnes Klingshirn among the 100 top global thinkers

We are very proud that our colleague Agnes Klingshirn is among the top 100 global thinkers 2010 according to the Foreign Policy’s annual list! In its December issue the American magazine "Foreign Policy" lists the 100 most important global thinkers. Next to Bill Gates, Barack Obama and Angela Merkel, a former GTZ colleague is among them: Agnes Klingshirn at 42nd position. Together with Peter Scott she has gained this position for advocating that clean and efficient cookstoves really make a change in improving the lives of people in poverty. Agnes Klingshirn organised and managed many stove projects for GTZ. She has been promoting clean and efficient cooking energy at all political levels for nearly 30 years, even when improved stoves were not "in fashion". Thus, she is regarded as one of the pioneers of the Global Alliance for Clean Cook Stoves.

New publications

Micro-gasification: Cooking with gas from biomass - An introduction to the concept and the applications of wood-gas burning technologies for cooking

This handbook is a compilation of the current state of the art of micro-gasification. It is the very first systematic overview on micro-gasifiers for cooking energy. Topics include „Wood-gas‟ from biomass and its application for cooking; Technologies and applications of micro-gasification to cookstoves; Feedstocks and fuels for micro-gasification.

Modern Energy Services for Modern Agriculture – A Review of Smallholder Farming in Developing Countries

The report highlights the important role played by modern energy services and related technologies in modern smallholder agriculture. It looks at the whole supply chain, from agricultural production, post-harvest and storage to the processing and commercialisation of crops. It also touches on the dual role of agriculture as energy user and producer and suggests management models to minimise risks for farmers by buying energy services on a fee-for-service basis.

Small-scale Electricity Generation from Biomass

By identifying potentials of and obstacles to biomass gasification, biogas and vegetable oil, the series outlines the opportunities of biomass for local, off-grid power generation. Part I: Biomass Gasification, part II: Biogas, part III: Vegetable Oil

Wood Energy – Africa’s Green Energy Future (Film, 8 min.)

The sustainable production of wood as a renewable energy source has huge potential for Africa. The afforestation of degraded landscapes, establishment of wood plantations and the sustainable management of natural forests can all serve to increase energy security, provide access to energy and reduce dependency on fossil fuels. The audio slideshow promotes the idea of wood energy as a modern and potentially renewable source of energy. It shows examples from different countries where wood is sustainably produced and processed efficiently for energy purposes. The short film (8 minutes) is available in English and French and can be accessed online via GIZ’s youtube channel. If you want to get hold of a hardcopy please contact GIZ HERA

Testing PicoPV systems in the field

PicoPholtovoltaic (PicoPV) systems, such as solar lanterns or micro solar home systems, provide a promising option for low-income households in rural areas. More than 100 firms are offering PicoPV systems in developing countries. But diffusion faces various challenges such as the low quality products, lack of warranty or maintenance services and lack of information in the private sector. Therefore, GIZ carried out laboratory tests the results of which are now being cross-checked with field tests. Tests concentrated on lamp designs and features preferred by local customers, lamp performance under real-life conditions, socio-economic impacts, and users’ willingness and ability to pay.
While field tests in Bolivia and Bangladesh are still being carried out, results from Uganda and Ethiopia are now available and will be published soon. In Uganda, seven lamp models were tested over three months. Interviews with 100 households showed the following:

Children used the lamp to study, men spent more hours reading and conducting productive work, while women conduct domestic work in the evenings rather than in the morning hours. The phone charging function proved an additional source of income for 70% of users.
Users preferred multi-purpose lamps with a 360° horizontal light cone, high illuminance level and similar design and functioning as the traditional hurricane lamps. Features that make usage easier, such as a handle at the top of the lamp and indication of switch position (on/off) were also favored. Furthermore, consumers appreciated solar lamps with the ability to adjust brightness and achieve different illuminance levels. Willingness to pay differed depending on the model but was usually lower than real market prices. The absolute maximum price users were willing to pay was USD 87.00.

In Ethiopia, nine lamp models were tested by 24 families in rotation. This qualitative study showed that access to solar lanterns alleviated the need for provision of energy by women. Due to the lower risk of accidents compared to kerosene lamps, children became more autonomous as parents could leave them alone with the solar lamps. Additionally, users stated an improvement in family life, since the solar lamp provided a large and bright light hence could be used simultaneously by various users. The quality of lamps was defined in terms of glare, cone of light, ease of operation for children and the presence of a regulator in order to change the level of brightness. Moreover, people chose white, bright light instead of a yellow one. A mobile charger was considered a nice feature, but the crucial factor for the testing persons was the light itself. Interestingly, reliable companies were an important selection criterion. Even low-income households were willing to pay more for products of high quality.
