Hydro power is a common method of energy generation in Mexico. Mexico's total installed power capacity from the year 2000, which utilized 20% of the Mexican Energy Supply (6368 PJ) was 36,697 MW. The capacity profile was: fuel oil 38.9%; hydro electricity 26.2%; natural gas 15.7%; coal 7.1%; dual 5.7%; nuclear 3.7%; geothermal 2.3%; 0.3% diesel. Hydro power provides 26.2% of Mexico's electricity, but mainly from large dams that greatly disrupt the ecosystems surrounding the rivers.<ref>Islas, J., F. Manzini, and M.

Micro-hydro power may be feasibly in various autonomous communities in the mountainous terrain of Chiapas. Drops in elevation can provide the amount of head necessary for sufficient energy generation from a micro-hydro power system. In this case head the measurement of pressure that comes from the the vertical distance between the upstream water surface and the downstream turbine. | ||
Although Chiapas remains one of Mexico´s poorest states, it contributes a great portion of the country´s electricity. Approximately 8% of the electricity users account for 50% of the state´s electricity use because the Federal Electricity Commission (EFC) levies tariffs on communities that cannot afford to pay for electric power.<ref>"Electrical Energy in Mexico and Chiapas: Rights, Resistances and Privatization," ''Maderas del Pueblo del Sureste, A.C.'' (July 2007): <nowiki>http://www.maderasdelpueblo.org.mx/pdf/DocENERGIA%20ELECTRICA%20MEXICO%20Y%20CHIAPAS.pdf</nowiki></ref> For this reason, many local Zapatista and autonomous communities resist paying for electricity and have learned how to maintain and repair their own power lines.<ref>Public denouncement of government tariff increases, ''Pueblos Unidos en Defensa de la Energia Eléctrica'' (23 November 2008)</ref> Such communities may therefore benefit from the increased independence provided by micro-hydro power for their lighting needs, refrigeration of medicines and maintenance of communication systems. | Although Chiapas remains one of Mexico´s poorest states, it contributes a great portion of the country´s electricity.
