Environmental Impact Assessment of Using Solar Heaters Instead of Electrical Heaters in The Highlands of Yemen

摘要

The required hot water for Household and other consumers in the Highlands of Yemen is obtained by means of Electrical Heaters (EH). The Highlands are defined by the areas located at altitudes of 1000 m above sea level or higher. This paper assesses Environmental Impact of using the Solar Heaters (SH) instead of EH. Accordingly the energy used for water heating is evaluated hence required solar heating systems for different household customers are identified. The energy produced by SH is evaluated and subtracted from the overall household energy consumption. Then equivalent fuel necessary to meet heating demand is calculated. Further the emissions reduction due to SH use is estimated showing the positive Environmental Impact of SH.
