Brazil, Mexico and Uruguay have adopted wind energy as a means to fight climate change. However, their experiences are different and insufficiently documented. This paper analyzes the advantages and disadvantages of the wind industry in light of its future expansion in Latin America. The methodology consists of the systematization and analysis of literature written in Spanish, Portuguese and English. Four advantages and five disadvantages were identified. The advantages are wind energy's reduced carbon footprint, low production costs, the potential for job creation and income from land rentals, while the disadvantages are possible vegetation loss, impact on birds and water sources, oil and waste contamination and health damage. The challenges for public policy are: supporting research on the socioenvironmental impacts of the wind industry and designing tools for their mitigation; developing a full supply chain of materials through technological innovation; distributing the benefits of wind energy equally among the local population, and prioritizing public needs of electricity above the interest of the private sector. If these challenges are not fully met, wind energy projects will be part of a hegemonic structure that claims to solve the problems created by climate change, while in fact continuing to use an extractivist logic, incapable of benefitting people.

The concept of Carbon Footprint, its origin, its relation with greenhouse gases and the methods to quantify it are presented and analyzed. The so-called greenhouse effect causes that the energy that reaches the earth at a certain rate is returned to a slower rate, increasing the temperature of the earth surface. Additionally, it is nowadays accepted that this effect is produced by some gases that are naturally emitted or produced by human actions. The Carbon Footprint is considered to be one of the most important tools for quantifying greenhouse emissions and in a general form it represents the quantity of gases emitted to the atmosphere and that is produced by human activities, and by goods and service consumption. Since there is no consensus about the definition of Carbon Footprint or the forms of quantifying it, this first part of the paper series analyzes the main concept and the main present views on the Carbon Footprint.
