Energy consumption is undoubtedly the second source of greenhouse gas emissions after agriculture. However, it is technically possible to achieve significant reductions in greenhouse gas emissions by complying with the schedule for renewing worn or obsolete infrastructure and equipment. Mitigation measures in the field of energy are diverse. These include the more efficient conversion of fossil fuels, the application of energy efficiency measures in different sectors (industrial, tertiary, building, households), the promotion of renewable energies, etc.... Several Technology-based GHG Mitigation options have been proposed to reduce greenhouse gas emissions in the energy sector, particularly in the production of electricity. For example, in the short to medium term, the schedule for decisions on GHG mitigation measures (such as CO2 the most important gas in the energy sector in Haiti) should contain the following elements: the modernization of existing installations - l use of higher energy efficiency technologies for new units to be installed - or the renovation of old plants using new modern and efficient technologies such as the decarbonisation of fuels and the use of lower carbon fuels the switch from fuels fossil fuels to natural gas or when the costs justify it, the outright use of cleaner liquid fuels. Similarly, the generation of electricity from renewable energy sources: solar, wind and even hydroelectricity already in operation, is possible in the short and medium term as a mitigation option for Haiti.
