Mexico vs. oECD: Risk Index scores
Except for a few years in the early 2000s, Mexico’s energy security since 1980 ranked first or second in the large energy user group, and with a score of 928 was number two in 2012. Mexico’s 2012 energy security risk score, however, is much higher (219 points) than its 1980 score, and it risks are increasing at a faster rate than for the OECD as a whole. As a result, Mexico’s relatively strong position is shrinking: From a 1980 score 29% better than the OECD average, its score in 2012 was just 12% better.
Mexico scores well primarily because of its comparatively good fossil fuel import, energy
expenditure, and per capita energy use scores. Mexico has a large domestic energy sector, focused primarily on oil. Oil production levels are declining, however. Output from Cantarell, Mexico’s largest oil field located off Mexico’s southeastern coast, has fallen sharply in recent years, and increases from other fields have not been enough to offset this decline, resulting in a 25% reduction in oil output over the past decade. The State-owned oil company Petroleos Mexicanos (Pemex), nationalized in 1938, is one of the world’s largest, and under the Mexican constitution, it is granted what amounts to a monopoly on the exploration, processing, and sale of petroleum. Not wanting to be left behind the boom in oil production occurring in the United States and Canada, the Mexican government recently moved to modernize its oil sector by amending its constitution to give private energy companies a share in oil production and licenses. The move is designed to attract investment in shale deposits and ultra-deep water oil, in particular, and could potentially open up vast untapped oil and natural gas reserves and reverse the slide in Mexican output. Mexico has very large reserves of natural gas, and it is a fairly large producer of natural gas, but many reserves remain untapped. Since 1989, natural gas imports have had to supplement domestic supplies and meet demand. Mexican imports of U.S. natural gas have nearly doubled since 2008 and could conceivably take 10% of U.S. production. Mexico is reportedly planning about 5,450 miles of new gas pipelines across the country, most of which will be focused on accessing U.S. shale gas. Moreover, with LNG terminals on both the Gulf and Pacific coasts, Mexico now imports LNG
from as far afield as Indonesia, Nigeria, Peru, Yemen, and elsewhere. Mexico also produces modest amounts of coal but has been a net importer of this fuel over the entire 31-period.
Mexico has potentially large shale oil and natural gas resources. EIA estimates Mexico’s shale gas resource at 545 trillion cubic feet, comparable to EIA’s U.S. estimate, and its shale oil resource at 13.1 billion barrels of crude oil, an amount about 30% higher than its proved reserves. Moves to loosen restrictions on foreign investment were triggered in part by a desire to bring into the country the expertise to tap these resources. Mexico’s power sector has become increasingly diverse. Thermal power plants dominate, in particular natural gas plants. Over the past decade or so, Mexico has been backing out oil-fired generators and replacing them mainly with natural gas. The country also employs coal, hydroelectric power, and one nuclear reactor.
Mexico enjoys a clear comparative advantage in those metrics measuring the costs of energy. The amount it spends on fuel imports per dollar of GDP generated is well below the OECD average. Moreover, its energy expenditures per dollar of GDP and per capita are lower, as are its costs for electricity.
The amount of energy each person uses, both overall and in the transport sector, and the amount of carbon dioxide each person emits also is less than the OECD average. The spread between the Mexican and OECD per capita consumption, however, has been narrowing over the last decade or so. As Mexico continues to grow and develop and its middle class expands, this difference should narrow even further. Mexico also scores comparatively worse in those aspects related to energy intensity and emissions intensity. One exception to this may be petroleum intensity. With oil being removed from the power sector, this metric is expected to continue to improve at a faster rate than that for the OECD average.
