Measuring the Incremental Costs of Global Environment Protection: The Case of Grid-Connected Wind Turbines in Morocco

An application is presented of the methodology used bythe Global Environment Facility (GEF) to measureincremental costs. Incremental cost estimates are usedby the GEF to determine its financial contribution toprojects that protect the global environment, such asinvestments in renewable energy. The importance ofadopting a system-wide view in certain types ofprojects (such as investments in grid-connected power)is illustrated using the case of wind power inMorocco. A narrow plant-by-plant comparison wouldneglect the adjustments in the system expansion planthat may be warranted when one type of plant (e.g., acoal fired thermal plant) is replaced by another (e.g.,a wind farm).

Assessment of groundwater contamination in a suburban area of Chennai,Tamil Nadu,India

Groundwater source is the major source of drinking water in most of the suburban areas of India. Groundwater quality was analyzed for pH, TDS, hardness, chloride, fluoride, nitrate, ammonia, phosphate, total coliform and E. coli for the period of January–December 2013. Samples were collected from 10 locations that include 10 shallow wells and 10 deep wells in each location. The quality variation between both shallow and deep wells during pre- and post-monsoon was analyzed. The improper disposal of solid waste and the distance of septic tank were pronounced on E. coli count. The analysis reveals that groundwater contamination is influenced by seasonal changes, environmental condition of the well and maintenance of the well. The high contamination was observed in the wells which are near to the Pallikaranai marsh, and during post-monsoon season, the total dissolved solids and nitrite parameters are slightly increased, whereas chloride increases during pre-monsoon season. Correlation analysis reveals that the chloride and nitrite have a significant relation. The results suggested that the groundwater immediately needs broader protection.
