Abstract
The share of natural gas in electricity generation in the world between 1973 and 2014 went from 12.1% to 21.6%, becoming the second largest energy source with a share in the world's electricity generation grid, behind only coal, which has a 40.8% share.. It is estimated that by 2040 there will be an increase in installed natural gas capacity of 2.2% per annum, so that the share of natural gas in the electricity matrix increases from 22% to 28% in that period. Some countries have chosen for the replacement of coal by natural gas in the generation of electricity, especially in the United States, which has seen a decrease in the use of coal since 2007 and a steeper growth in the use of natural gas. It can be also mention the United Kingdom, which started to exploit natural gas as a source of electricity in the middle of 1990 and not coincidentally, showed a decline in the use of coal. The objective of this work is to present an increase in the share of natural gas in the world energy matrix through the expansion of infrastructure (liquefaction and regasification plants) and it transportation. The work also aims to focus on the main characteristics referring to the generation of electric power by this source such as: CO2 emission indices, efficiencies, costs and capacity factor.
