Teaching Renewable Energies and Sustainability in the School of Diogo Vaz (São Tomé, Africa)

This work aims to show how sustainability and renewable energies could benefit a rural area of Africa (in São Tomé) by means of using solar energy and biogas. Applying these technologies requires ingeniousness and little founding, the favourable outcomes are becoming less dependent of fossil fuels (wood, coal and gasoline) while saving time and, more importantly, the forest. We have taught how to design, build and operate systems for cooking, lighting and water-heating that use renewable sources of energy.

Finned Pots as a Means of Increasing Efficiency

Finned Pots as a Means of Increasing Efficiency Dale Andreatta, Ph.D., P.E., dandreatta@sealimited.com, February 13, 2009

Finned PotFinned Pot

Executive Summary A pot with heat transfer fins has much greater surface area than pots with no fins. In theory, this could lead to greatly increased heat transfer to the pot for a given stove, and the pot would theoretically improve the performance of the stove under all conditions. While we often concentrate on the stove as the primary element of a cooking system, the efficiency of a stove is mainly determined by the heat transfer to the pot, and designing a better pot would be an easy way to make a more efficient stove. A variety of types of finned pots were built and tested. The best designs were separated out in the lab, using natural gas to simulate a wood flame. Several types of fins can be retrofit to existing pots. The better designs of finned pots performed well over a range of conditions using simulated stoves, and sometimes also with an actual wood burning stove modified to use natural gas to simulate a wood flame. With fins on or near the bottom of the pot the finned pots typically gave around a 1.76-fold improvement in heat transfer. If the fins were on the sides of the pot a greater than 2-fold improvement was achieved. Tests on actual stoves using wood as the fuel generally gave smaller improvements in performance, generally 1.33 or less, corresponding to a 25% or smaller reduction in fuel usage. These tests were done under a variety of conditions with a variety of stoves, including the open fire (3-stone fire). On industrial fuel stoves using kerosene or alcohol, improvements were even less, with the finned pots giving 1.2 fold improvements or smaller. In some tests the finned pot used more fuel than an unfinned pot. The reasons for this wide range of results is not known. It is not recommended that finned pots be pursued as a means of increasing the efficiency of stoves. Better results can probably be achieved with less effort by using skirts around the pot. These skirts could be attached to the pots with optimum dimensions. See attached report presented to ETHOS 2009

Fuel Efficient Stove Programs in IDP Settings - Summary Evaluation Report, Darfur

Fuel Efficient Stove Programs in IDP Settings - Summary Evaluation Report, Darfur
Academy for Educational Development for USAID, December 2008

  1. INTRODUCTION: EVALUATION OBJECTIVES
    Around the world, conflict and natural disasters have displaced millions of people. Displaced populations fleeing to settlement camps and seeking safety in host villages often put great stress on natural resources, leading to environmental degradation and conflict with local populations. One of the greatest needs of people affected by crisis, be they displaced, settled, or on the move, is firewood or some other type of fuel to cook their food, heat their homes, and treat water for drinking and food preparation. The risks endured (especially by women and children) collecting scarce wood resources constitute some of the most challenging and serious protection concerns both in IDP camps and in villages where conflict over resources is high.

USAID’s Office of Foreign Disaster Assistance (OFDA) has been one of the key US Government entities providing funding for humanitarian organizations implementing fuel-efficient stove (FES) programs in populations of internally displaced persons (IDPs). The FES programs are intended to help accomplish various goals, such as improved food security or decreased deforestation, by reducing fuel consumption. However, the large number of implementers, their varying program objectives and degrees of expertise, and differing conditions within and among IDP communities have made it difficult for OFDA to determine the relative efficacy of the FES interventions and provide guidelines for USAID-funded institutions working in IDP settings.

OFDA therefore enlisted the assistance of the USAID Energy Team to undertake a multi-phase evaluation in order to derive “best practices” for future FES interventions. While the primary purpose of this evaluation is to provide guidance to USAID-funded organizations, USAID hopes to inform the broader humanitarian community by sharing the results of the evaluation with other organizations. Eventually, the best practices will be developed into a series of recommendations and toolkits for use by NGOs, donors, and other groups operating FES programs in IDP settings.

Phase I of the evaluation (November 2006) was a desk study of recent FES projects in refugee and IDP settings. Based on the desk study findings, Phase II (December 2006) entailed the development of a methodology for conducting the evaluation fieldwork. Phase III involved on-site research in IDP camps in Northern Uganda and in Darfur. The Northern Uganda report has been completed and is available on USAID’s web site.1 Phase IV will entail the development of recommendations and tools to improve FES programs.
The Phase III field research in Darfur took place in two phases. First, a four-day review and training on the evaluation methodology and tools was held in Khartoum in March 2008 with the assessment team. The fieldwork in Darfur IDP camps took place from 16 April to 9 May 2008, with a six-person all-Sudanese team composed of technical stove experts and social scientists. Three OFDA-funded NGO FES programs, one in each region of Darfur, were selected for assessment. However, due to continued security concerns and the difficult logistics of deploying a team of investigators into Darfur, it was possible to include only two regions in the assessment. This report summarizes findings regarding programs being implemented by two organizations in Otash Camp in Nyala, South Darfur, and one organization in Kabkabiya near El Fasher, North Darfur. The implementing NGOs are not named in this report and are identified only as NGO A, B, and C.

The evaluation methodology incorporated a number of different tools to collect both quantitative and qualitative data on the FES programs. The underlying objectives were to determine 1) if the FES interventions were meeting their fuel saving goals, and 2) why or why not. Specific areas examined included:

  • •cooking technologies
  • •user outreach and education programs
  • •stove production and dissemination strategies
  • •FES project monitoring and evaluation (M&E) frameworks

In total, the field team conducted 150 household energy surveys, 66 controlled cooking tests, and 50 water boiling tests, as well as camp and programmatic surveys, focus group discussions, and informal participant observation and interviews. This summary report consolidates the findings from the three Darfur program evaluations and presents OFDA with preliminary recommendations designed to improve the impact and quality of its future support to FES activities in IDP situations. Final recommendations and guidance from “lessons learned” will be developed from the findings of both the Darfur and Northern Uganda assessments.

Carbon Credit Monitoring
David Mukisa, Uganda Stove Manufacturers Limited (Ugastove), November 2007
UgastoveUgastove
PCIA Africa Regional Workshop, Pretoria, Oct--Nov 2007

BACKGROUND
•Uganda Stove Manufacturers Ltd (UGASTOVE) was until recently called UCODEA, short for Urban Community Development Agencies.
•It is a progressive improved stove business based in Kampala, Uganda, producing and selling both household and institutional stoves
•Name was changed to ease recognition and distinction as we look forward to branding/ patenting.

The stove project benefited from a US EPA grant in 2004-2006, which funded the construction of production infrastructure, perfection of stove design,
IAP monitoring, market research, part of the KPT costs, and design of business development processes to support the commercialization of the product.
Project won an award for the effort in stove design and improvement at the 3rd Biennial PCIA Workshop in Bangalore, India, March 2007.

Successful IAP monitoring was done according to CEIHD monitoring protocols (Preliminary data shows that UGASTOVE’swood burning stove reduces CO by 54% and PM 2.5by 49%)

KPT successfully done in 2006, follow up in 2007 (Field tests show that the stoves reduce the consumption of fuel by 38-58% compared to traditional stoves).

Lab GHG emissions tests carried out at UCB, enabled the drafting of the PDD based on the scientific data gathered during the said surveys.

Carbon credit program was launched in February 2005 at UC Berkeley, with the intention of registering the credits on the Gold Standard for VER.

In March 2007, the first consultative meeting was held in Kampala as required for the Gold Standard projects

In partnership with CEIHD, a monitoring plan was drafted and forwarded for approval on the Gold Standard.

Introduction to Gold Standard/Carbon Credits
Dean Still, Nordica MacCarty, Aprovecho Research Center, July 23, 2008
Gold StandardGold Standard

There has been a lot of interest recently in carbon credit financing for improved stove projects. Since 2006, stove organizations have begun to receive funding from carbon credits. The Gold Standard has just published a set of protocols formalizing how stove projects can prove the lowering of emissions. Large financial institutions, like Climate Care/JP Morgan, are now participating in the relatively new market.
