RANGEL JIMENEZ, Andrés Eduardo  e  PORTILLA SALAZAR, Carlos Johnny. The process for replacing heavy fuel oil with natural gas in industrial companies of Valle del Cauca and Cauca - Colombia 2004-2012. Apuntes del Cenes [online]. 2016, vol.35, n.61, pp.237-266. ISSN 0120-3053.

This paper has the main purpose to analyze the replacement process from heavy fuel oil toward natural gas by median and big companies located in Valle del Cauca and north of Cauca in the period 2004-2012. Likewise, using a linear probability Panel Data model, the replacement propensity from higher polluting fuel toward natural gas of these industries is estimated. The results show that the difference in spending on natural gas to other fuel usage is determinant to the probability of replacement. In addition, it is confirmed that industries with less likelihood of replacement are those that use coal in production processes.

Palavras-chave : Alternative energy sources; gasification; panel data model.
