This paper compares the cost of electricity generation with a coal fired plant and a wind mill in Chile’s Central Interconnected System. To the standard costs of coal generation (capital investment and fuel) we add local and global environmental externalities. The environmental cost of generating with coal is US$17/MWh, and the total cost is US$78/MWh. Wind generation is considerable more expensive, US$136/MWh.// En este artículo comparamos el costo de generar electricidad con carbón y con viento en el Sistema Interconectado Central de Chile (SIC). Hemos incluido el costo ambiental local y global, así como los respaldos térmicos necesarios para mantener la misma confiabilidad del suministro eléctrico. El costo medio de generar con carbón, que incluye externalidades ambientales por 17dólares/MWh, es de 78 dólares/MWh. El costo medio de generar con viento es considerablemente mayor, 136 dólares/MWh.
