Initial stages of production:  Metal is transported in a company-owned truck from Dakar to local metal workers.  While this truck transport generates emissions, it also provides part-time employment for one staff member.  If all parts were imported, additional emissions would be generated and any time lag in delivery would cost the company money.  Importing would also require paying import taxes, a cost that would ultimately be passed on to the user.  

Employment:  Producing locally also stimulates employment.  VEV has 3 permanent employees and 5 temporary/day workers, most of whom are involved in producing parts.  Everyone except for the head technician works 5 to 8 hours per day and less than 6 days a week.   The permanent staff, two of whom have received training at VEV, is generally satisfied with workplace conditions, salary, and safety precautions.  Some of the temporary staff have complained about safety, salary, and the sporadic work.

Production of parts:  The welding involved in the production process is energy intensive and uses fossil fuel and emits CO2.  However, as mentioned above, the fact that the parts are produced locally means there are no emissions from transporting imported parts. While exact numbers are not available, it is probable that local production results in less overall emissions. The only waste from the production process is scrap metal, which is either reused or sold to scrap metal dealers. 

Inventory:  The AREED funds were used in part to make sure the company had enough of a parts inventory to be able to make repairs as needed.  Both the imported and locally made parts go into the inventory, ready for when a repair is needed.  However, even after the funds were distributed, there were still problems with adequate inventory, and this was limiting business.  As it there were no figures available to compare inventory before and after AREED funds were used, it is difficult to ascertain if the problem was that the funds were not effectively used, or if business expanded and the company simply was not able to keep up with the demand.

Installation:  Both installation and pump repair involve transportation and generate emissions, but also create jobs. Installations tend to be larger jobs and thus create more revenue and employment for the local community down the value chain.

Wind pump use:  The actual use of the wind pumps generates the greatest overall benefits.  In 2008, VEV had repaired and/or installed pumps that provided 43,175 people access to a total of 1,859,259,750 liters of water. Communities used this water for home use, gardens, livestock, and masonry. The pump size depends on the size of the community, reservoir capacity, and wind availability. The equipment can pump anywhere from of 950 to 9000 liters of water per hour from a depth of between 5 and 80 meters underground. This access to water saved time and lightened the workload for women, and increased income generation opportunities.  On average, women saved 2 to 3 hours that would have been spent traveling to a neighboring well to collect enough water for the day. This extra time was spent on income generating activities, education, or leisure. Wind pump use also positively impacted education, health, quality of life, cost savings, environmental awareness, and gender equality. 

End-user feedback:  The end-users cited a number of issues with the pumps, but across the board everyone wanted more water.  Suggestions included more faucets, a higher-capacity pump, a hybrid system with a diesel generator for when there is no wind, and a larger reservoir.   Many wanted more water so they could have a garden.  While water was traditionally used for both domestic use and gardening, end-users say that today there is not enough water for gardens because of increased domestic demand.  There were also complaints about the frequent need for repairs.  Some of the systems were over 10 years old and equipment had become dilapidated.  Some users wanted to develop a metered water conveyance system that would provide water directly to houses, schools, and health centers.
