The Reaction of the Consumption of Fossil Fuels to Trade Openness in Latin America & the Caribbean Countries

This article investigates the impact of trade openness and renewable energy on the consumption of fossil fuels for a panel of fourteen LAC countries over the period from 1990 to 2014. To this end, a PARDL model in unrestricted error-correction form is estimated, and robustness checks are performed by estimating a PNARDL model. The results of the PARDL model point indicate that the impact of economic growth and elasticity of trade openness are statistically significant at the 1% level and contribute to increased consumption of fossil fuels in the LAC countries. However, the impact and elasticity of consumption of renewable energy are statistically significant at 1% and 5% levels and thus contribute to decreasing consumption of fossil fuels. Nevertheless, the asymmetry of the impact of consumption of renewable energy and its elasticity decrease the consumption of fossil fuels. Therefore, the positive impact of trade openness on the consumption of fossil fuels suggests that the process of globalisation by trade liberalisation in the LAC countries is not sufficient to bring more investment that encourages R&D in energy efficiency technologies, and equipment that reduces the consumption of energy from non-renewable energy sources by households and firms.


Introduction
The classical Heckscher-Ohlin theory of international trade suggests that in the context of free trade, developing countries would specialise in the production of goods that are produced with relatively abundant factors of production (for example, natural resources and labour force), while developed countries would specialise in the production of goods that are more capital and human capital-intensive. . According to the same authors, trade openness is characterised by the movement of goods and services produced in one country and then further processed or consumed in another country. Indeed, without the use of energy, the production of such goods and services would not be possible. This use of energy in the production of goods and services is affected through changes in the growth of the economy (scale effect), through changes in the structure of the economy (composition effect), and through changes in the techniques and technologies that are used for production (techniques effect) (e.g., JENA andGROTE, 2008 andGHANI, 2012).
In the scale effect, liberalisation will increase economic activity because of static-dynamic gains from trade. That is, the increase in economic activity will increase energy consumption (GHANI, 2012). The composite effect of the consumption of energy depends on how the structure of the economy is affected by liberalisation. That is, this effect indicates that the use of energy-intensive changes according to the economic development, for example from agriculture to an industrial economy; this change occurs in the initial stages of economic development, where the economy is based largely on the agriculture sector, and consequently the use of energy is relatively less . The same authors add yet that when the economy changes from agriculture to industrial, the use of energy increases. Moreover, GHANI (2012) adds that, in most cases, the technique effect reduces energy consumption as improvements in technology due to technology transfer improve energy efficiency. SHAHBAZ et al., (2014) also refer to this as the technique effect, when developing countries import of advanced technologies and consequently increase the production of outputs with low energy consumption.
Indeed, the scale, composition and technique effects are possible through trade openness that allows the developing countries to import advanced technologies from developed countries .
This process of trade openness improves the transfer of new technologies helping technological progress and brings about a consequent improvement in productivity (ZAHONOGO, 2016). This technological progress, as mentioned before, consists of intermediated manufactured products, capital equipment, technological goods, electronic equipment, and new material that are commercialised in international markets, where it allows countries to import the R&D done by other countries (HENRY et al., 2009). Moreover, ZAHONOGO (2016) adds yet that this consensus rests on the assumption that trade creates economic incentives that boosts productivity, where trade reduces misallocation of resource use in the short run, and in the long run facilitates technology transfer among countries.
Therefore, this technology transfer by international trade takes on even greater importance for productivity growth in developing countries, as this group undertakes little domestic R&D and therefore has few domestic sources of new technology (HENRY et al., 2009). According to COE et al. (1997) thane increase of 1% in the Research and Development (R&D) capital stock in industrialised countries raises the output in developing countries by 0.06%. This evidence makes it clear that the importance of international trade is substantial for developing countries.
Moreover, energy affects trade openness in various ways. First, the energy is an important production factor, where the equipment and machinery in the process of production require energy. Second, the exports and imports of manufactured goods or raw material require energy for fuel transportation . For this reason, the study of this relationship is essential. This is different from the relationship between economic growth and consumption of energy that started to be investigated in the 1970s by KRAFT and KRAFT (1978). The study of the relationship between trade openness and the consumption of energy has a different trajectory. This topic is very recent, with the first study investigating this relationship produced by COLER (2006). The author explored this relationship in 91 high-, middle-and low-income countries in the period 1980-2010. The empirical results of their study pointed to the existence of a feedback effect between trade openness and energy consumption.
Despite the initiative of COLER (2006) in realising the first investigation about the impact of trade openness on the consumption of energy, this topic still has not received much attention from researchers, and the scarcity of academic studies impairs understanding of how trade openness and consumption of energy, in fact, interact with each other (KOENGKAN, 2018d).
In the Latin America & the Caribbean (LAC) countries, the consumption of energy has more than doubled in the last 40 years. However, this growth has not been constant (KOENGKAN et al., 2019b).
Indeed, it was in the 1970s that the consumption of fossil fuels proliferated, as the economic activity and trade openness of the region grew greatly (KOENGKAN et al., 2019b).
From the 1980s to the 1990s, the economic activity of the region entered into decline with the debt crisis that led the economy of Latin American countries into deep recession followed by a slow recovery (KOENGKAN et al., 2019a). It was also in this period that, according to TISSOT (2012), the consumption of energy from non-renewable sources rapidly expanded in the region, while the consumption of energy from renewable sources declined.
The prominence of non-renewable energy sources in the energy matrix of LAC countries derives from the fact that some countries are ranked among the most significant oil producers in the world, i.e., Argentina, Brazil, Colombia, Mexico, Venezuela (RB), Ecuador, and others are significant importers, i.e., Brazil, Chile, Dominican Republic, Uruguay, and Paraguay (FUINHAS et al., 2017). These countries are benefiting from plunging oil prices because they will have to pay less for their oil imports, as well as some places where the generation of energy depends on oil products (KOENGKAN et al., 2019b). According to JURADO (2018), although Brazil is the second major oil producer in the region, the country is the biggest net oil importer as it is the top oil consumer in the LAC region. Moreover, Venezuela (RB), Brazil, Colombia, Argentina, and Ecuador are responsible for 85% of total oil production in the region (IEA, 2018).
Non-renewable energy sources accounted for 46% of the primary energy supply in the LAC region in 2013, while they averaged 31% worldwide (KOENGKAN et al., 2019b). According to IRENA (2016), natural gas represents 23% of the primary energy consumed in the region. Despite this, the region has one of the most significant shares of renewable sources in the energy mix (KOENGKAN and SOUSA, 2019d).
The first sustained experience with trade liberalisation in the LAC region was in Chile in the 1970s, when this country became one of the most open in the entire world. In the 1980s, other countries such as Bolivia, Costa Rica, and Mexico in 1989 followed this trend and gradually opened their markets. In the early 1990s, more countries joined this movement, including Argentina, Brazil, Colombia, Peru and Venezuela (RB) (AGOSIN and FRENCH-DAVIS, 1993). In order to answer these questions, the effect of trade openness on the consumption of energy from non-renewable sources will be analysed using a dataset comprising data for fourteen countries from the LAC region for the period from 1990 to 2014. The Panel Autoregressive Distributed Lags (PARDL) model in the form of Unrestricted Error-Correction Model (UECM) is used as our central model estimation, and a Panel Non-linear Autoregressive Distributed Lag (PNARDL) model will be applied to check the robustness of the results. That is, the main objective of this article is to identify the effect of trade openness on the consumption of fossil fuels in the LAC countries.

Materials and methods
Section 2 is divided into two parts: (2.1) presents the materials and variables that will be used, and (2.2) describes the adopted method strategy that will be applied in this investigation.

Materials
To accomplish the goal of this investigation, annual data was collected from 1990 to 2014 for fourteen countries from LAC region, i.e., Argentina, Bolivia, Brazil, Chile, Colombia, Dominican Republic, Ecuador, El Salvador, Guatemala, Mexico, Nicaragua, Panama, Peru, and Venezuela (RB). Why were LAC countries used for this study? LAC countries were chosen on the grounds that: (i) they have experienced a rapid process of trade openness that started in the 1970s and intensified at the end of the 1990s; The variables which were chosen to perform the empirical analysis are: Trade expansion and technological development have increased energy demand in the last decade.
Indeed, international trade and consumption of energy tend to move together. So, for this reason, it is necessary to learn more about the effect of trade openness on the consumption of energy.
The variable trade openness (TR) was used by several authors (e.g., KOENGKAN, 2018d;NASREEN and ANWAR, 2014;SEBRI and BEN-SALHA, 2014;SBIA et al., 2014;MANAGI et al., 2009) and was chosen in this study because it is an essential component of economic growth and consequently increases international trade, economic activity and finally the consumption of energy (SADORSKY, 2012). Indeed, trade openness enables developing economies, which is the case of LAC countries, to import advanced technologies from developed countries. Therefore, the adoption of advanced technology lowers less energy use and produces output. Indeed, as trade openness is considered one of the potential factors that induce higher economic growth, and energy demand is expected to rise to respond to economic growth.
For this reason, the variable Gross Domestic Production (Y) was used in this model.
Regarding the consumption of renewable (REC) and fossil (FOC) fuels, these variables were chosen in this investigation because the rapid development of renewable energy technologies will consequently decrease the consumption of non-renewable. The increase of production and consumption of fossil fuels in the region encourages the use of these variables. Moreover, the energy was used in this study because the import and export of goods and services need energy. Therefore, without a suitable energy supply, trade openness will be adversely impacted. That is, energy is an essential input in trade expansion, where suitable energy consumption is crucial for expanding trade via imports and exports.
The use of time-series from 1990 to 2014 is due to the availability of data until 2014 for the variable REC for all countries selected. The LAC countries were selected due to the rapid process of trade openness and consumption of fossil fuels and others. The availability of data is another motivation.
The variables FOC, Y, and REC were transformed into per capita values with the total population of each cross. The per capita value allows disparities to be controlled for in population growth over time and within countries (e.g., KOENGKAN et al., 2018b;KOENGKAN, 2018c;KOENGKAN, 2018d).

Furthermore, this investigation used the GDP in constant 2010 US$ instead of the constant Local Currency
Unit (LCU). The initial estimations using constant 2010 US$ presented slightly different results from when constant LCU was used. Indeed, these changes in results could be related to changes in the database source, as the old database from IEA was replaced by the World Bank database or by the exchange rates themselves.
The variable of trade openness is the result of trade and economic liberalisation that is the integration of the national economy with the rest of the world. This integration has been one of the most important developments of the last century. Indeed, this process of integration, often called "globalisation'", has materialised remarkable growth in trade between countries. Table 1 shows the summary statistics of variables. Moreover, we should stress that they are already in their natural logarithms (see prefix "Ln").

Methods
For the realisation of this investigation, the PARDL model in the form of UECM will be used as our central model estimation, and a PNARDL model will be applied to check the robustness of results. The This model was employed in empirical researches that have several applications in the literature. Table   2 shows PARDL models applied in the literature.
The general PARDL model in the form of UECM follows the specification of Equation (1): where represents the intercept, and , with k = 1, …, 3, denote the estimated parameters and is the error term. The prefixes "Ln" and "DLn" denote natural logarithms and first-differences, respectively.
Therefore, before the PARDL model estimation, it is mandatory to examine the characteristics of the variables, which includes the cross-section and time series, as well as to ascertain the presence of specificities which, if not considered, may produce inconsistent and incorrect results. To this end, the preliminary and specification tests will be performed before estimating the model of interest.
effects model. The latter is used due to the large T (number of time-series observations) and the small N (number of cross-sectional observations) in the panel.
To appraise the robustness of results in the PARDL model, the PNARDL approach will be used. This model is an asymmetric extension of linear PARDL model in the form of UECM developed by GRANGER (1981) and by ENGLE and GRANGER (1987). Indeed, the PARDL model in the form of where the equilibrium relationship between and is divided into positive and negative effects, plus the error term means the possible deviations from the long-equilibrium. As shown in Equation (2), the effect of the variable can be decomposed into two parts, positive and negative (see where represents the random initial value and denote partial sum processes which accumulate positive and negative changes, respectively, and are defined as (see Equations 4 and 5): Then, the general PNARDL model in the form of UECM follows the specification of Equation (6): ). Therefore, the parsimonious PNARDL model in the form of UECM follows the specification of Equation (7): where represents the intercept, and , with k = 1, , 3, denote the estimated parameters, , , and Ln^{-}_{it-1}$ are the partial sums of positive and negative changes in variables DLnREC and LnY, respectively and is the error term. Additionally, the PNARDL model approach allows the use of a combination of variables I(0) and I(1). Nevertheless, it is essential to check the integration order of variables in previous steps as the PNARDL model is not valid for variables that are I(2).
This section shows the data/variables and methodologies and their preliminary and specification tests that will be used in our analysis. The next section will show the empirical results.

Empirical Results
As previously explained, this section will present the empirical results of preliminary and specification tests as well as the results of PARDL model estimation. The first step was the computation of VIF and CSD-tests. The first test informs the presence of multicollinearity, while the second shows cross-sectional dependence. The VIF test helps us to understand the degree of multicollinearity, which may be present in our model and which can lead to problems in estimation. The null hypothesis of CSD test is the presence of CSD in all variables. Therefore, in Table 5 we can see the results of VIF and CSD-tests, both in firstdifferences and natural logarithms. Notes: ***, **, * denote statistically significant at 1%, 5%, and 10% level; the Stata command estat vif and xtcd were used; (Ln and DLn) denote variables in natural logarithms and first-differences of logarithms respectively.
The information that is present in the previous table indicates that multicollinearity is not a concern in the estimation, given the low VIF and mean VIF values registered, which are lower than the usually accepted benchmarks of 10, in the case of the VIF values, and 6 in the case of the mean VIF values.
Concerning the CSD-test, we see that the null hypothesis is rejected in all cases, leading us to the conclusion that there is a correlation between the series across countries.
In the presence of CSD, it is necessary to assess the order of integration of the variables. To this end, the Pesaran CADF test was computed. This test is robust in the presence of CSD, and we did not opt to use the first-generation test for the reason that it is inefficient in the presence of CSD. The null hypothesis of Pesaran's CADF is that all series are non-stationary I(0). The results of this test can be seen in Table 4. The results from the Pesaran CADF test show that none of the variables seems to be I(2), although they show that some of them may be in the borderline between the I(0) and I(1) orders of integration (i.e., in the first-differences with and without trend, and all variables in natural logarithms without trend, and also FOC and REC with trend seem to be stationary).
After the realisation of the unit root test, the next step is to assess the presence of individual effects in the model. To this end, the Hausman test, confronting random (RE) and fixed effects (FE), was performed.
The null hypothesis of this test is that the difference in coefficients is not systematic, (i.e., random effects are the most suitable estimator). The Hausman test indicates that the null hypothesis should be rejected ( (7) = 95.79, statistically significant at 1% level) (see Table 5 in Appendix) and that a fixed-effects model is the most appropriate for this analysis.
To assess the presence of heterogeneity/homogeneity in the panel, the MG, PMG, and FE techniques were performed. The MG estimator that was developed by Pesaran and Smith (1995) calculates the average of coefficients of all individuals, with no restrictions regarding the homogeneity of short and long run.
However, the PMG estimator created by PESARAN et al. (1999) permits for differences in error variances, short-run coefficients, speed of adjustment and intercepts (i.e., these parameters may be country-specific), but it imposes a homogeneity restriction on the long-run coefficients (i.e., they should be equal across countries).
Then, the PMG estimator can combine the "pooling" from the FE estimator with the "averaging" from the MG estimator. However, in the presence of panel homogeneity in the long-run, this estimator is more efficient than the MG estimator. Table 6 shows the outcomes for the three specifications (e.g., MG vs PMG; PMG vs FE; and MG vs FE). Results are presented in Table 7. estimators and shocks are displayed in Table 8.  Although we present the results of the model with these three estimators, we should clarify that we will base our inference on the FE Driscoll and Kraay estimator, given that it is the most robust. The inclusion of the other two estimators (i.e., FE and FE robust) was mainly linked with the possibility of seeing the differences between them, i.e., seeing the changes in the results when we control/do not control for the phenomena which were detected in the specification tests.
The results of PARDL model estimation indicated that, in the impact of variable Y, and elasticity of TR are statistically significant at the 1% levels, and thus both contribute to the increasing of FOC in the LAC region. However, the impact and elasticity of REC is statistically significant at 1% and 5% levels and thus contribute to the decrease in consumption of non-renewable energy in the region. Regarding the ECM term, it is negative and statistically significant at the 1% level. In the next section, the robustness check will be shown with the realisation of PNARDL model. This verification will be made to test if the coefficients generated by PARDL are consistent with the change in methodology approach.

Robustness check
In this section, we assess the robustness of our results using a PNARDL approach. This model, as  Tables 1, 2, 3, and 4 in Appendix .
Therefore, the preliminary tests in PARDL and PNARDL are the same.
The results of the heterogeneity/homogeneity test also indicate that the FE technique is the most appropriate for the fixed effects homogeneous model (see Table 8 Table 9 in Appendix). Estimates for PNARDL model coefficients are shown in Table   10.  Notes: ***, ** denote statistically significant at 1%, and 5% level, respectively; the ECM denotes the coefficient of the variable LnFOC, lagged once; (Ln and DLn) denote variables in natural logarithms and first-differences of logarithms respectively; the H0 of Wald's parameter equality test is the existence of symmetry.
The PNARDL indicates that the impact of Y and the positive and negative asymmetry of their elasticity, and the impact of TR and its elasticity contribute to an increase in the consumption of nonrenewable energy. However, the asymmetry of the impact of REC and their elasticity decrease the consumption of non-renewable energy.
The results of PNARDL indicate that the impact of REC and the elasticity of Y are asymmetric nonlinearity. Indeed, only these two variables, i.e., REC and Y, were added in this estimation due to their statistical significance in the model regression. Furthermore, the coefficients of shocks and variables remain statistically significant at the 1% and 5% levels, and the ECM term remains negative and statistically significant at the 1% level. The next section will present a more thorough discussion of the results from the model estimations.

Discussions
This investigation approaches the effect of trade openness on non-renewable energy sources in fourteen countries from the LAC region. The results of the preliminary tests indicate the presence of low multicollinearity and CSD in the data (see Table 1). Indeed, the presence of CSD in all variables in the first-difference and natural logarithms is mainly the result of the interdependency that exists across the economies in the countries from our sample.
The results of Pesaran's CADF test indicate that the variables in the first-differences with and without trend, and all variables in the natural logarithms without trend, and also the variables FOC and REC with trend are stationary, while the variables Y and TR in natural logarithms and with trend are non-stationary (see Table 2).
This indication reinforces the fact that the PARDL model is the best approach for this analysis and the reason that, as was previously explained, it allows for the incorporation of variables that are I(0) and I (1) in the same estimation. Indeed, due to stationarity in the variables in first-differences and natural logarithms, it is not necessary for the realisation of the cointegration tests. The Hausman test indicates that the null hypothesis should be rejected ( (7) = 95.79), statistically significant at 1% levels) (see in Table 4 in Appendix) and that a fixed-effects model is the most appropriate for this analysis, and the heterogeneity/homogeneity test also indicates that the FE technique is the most appropriate for the fixed effects homogeneous model (see Table 5). The specification tests indicated the presence of heteroscedasticity and first-order autocorrelation, as well as the non-presence of correlation and dependence in the residuals (see Table 6). Therefore, the FE, The possible explanation for the negative impact of consumption of renewable energy on nonrenewable in the LAC countries is due to the vast abundance of renewable energy sources i.e., solar, photovoltaic, wind, hydropower, geothermal, and waste, in these countries which stimulate investment in renewable energy technology and consequently decrease the consumption of non-renewable (FUINHAS et al., 2017).
According to KOENGKAN (2018c), this negative impact of renewable energy consumption on fossil fuel consumption demonstrates that the renewable energy policies in the LAC countries are effective and can encourage the development of renewable energy technologies and the consumption of energy from this kind of source. The author also claims that this results in evidence that renewable energy technologies used in these countries are effective in reducing the consumption of non-renewables and environmental degradation.
However, this capacity of renewable energy to reduce the consumption of fossil fuels could be related to the process of globalisation via financial openness that increases capital stock and consequently reduces the cost of external financing, encouraging investment in renewable energy technologies (KOENGKAN et al., 2019f).
Thus, the reduction of fossil fuel consumption by renewable energy found in this analysis confirms the process of "energy transition" in LAC countries. According to HAUFF et al. (2014), the term "energy transition" indicates a growing trend of the share of renewable energy sources to reduce the consumption of fossil fuels. Indeed, this term gives a clear objective of reducing environmental degradation.
The impact of the reduction of renewable energy consumption on the consumption of non-renewable energy is modest. According to YORK (2012), this low impact of renewable energy on non-renewable energy is related to the expansion of the production of renewable energy that will suppress that of nonrenewable energy. For this author, the failure of renewable energy sources to displace fossil fuels is probably in part related to the established energy system as the result of lock-in to using renewable energy sources as the base of the energy mix. This could be related to the prevalence of infrastructures and economic policies that support the fossil fuel industry. Moreover, this low capacity for renewable energy sources to decrease the consumption of fossil fuels could be linked to periods of low production caused by drought or climate change. In such cases, in order to attend to the energy demand, thermoelectrics powered by fossil fuels are activated. According to KOENGKAN et al., (2019g), the renewable and fossil fuel energy sources substitute each other in the energy matrix in the Latin American countries.
Finally, the positive impact of trade openness on the consumption of non-renewable energy is in line with some authors that investigated this relationship (e.g., KOENGKAN, 2018d;SEBRI and BEN-SALHA, 2014;HOUSSAIN, 2011;COLE, 2006;JENA and GROTE, 2008 Additionally, the positive and negative asymmetry of the variables in first-differences of REC and natural logarithms of Y are not asymmetrically different. The Wald's parameter equality test (positive and negative asymmetric) clearly supports this evidence.These results indicate that the model that we formulated is robust to changes in methodologic approach (see Table 10).
This section discussed possible explanations for the positive impact of trade openness and economic growth on the consumption of fossil fuels, and for the negative impact of renewable energy consumption.
The next section will focus on the policy implications of the empirical anaylsis' results.

Conclusions and policy implications
The main aim of this investigation is to analyse the impact of the trade openness on the consumption of energy from non-renewable sources. Fourteen LAC countries were selected in a period 1990 to 2014. This investigation opted to use PARDL as the methodology in the form of a UECM and to check the robustness of the main model PNARDL was used.
The preliminary tests of this study indicated that the variables used have characteristics such as lowmulticollinearity, cross-sectional dependence in the variables in logarithms and first-differences, and in almost all cases, I(0)/I(1) for all variables, and also the presence of fixed effects. Additionally, the specification tests indicated the presence of heteroscedasticity and first-order autocorrelation, as well as the non-presence of correlation and dependence in the residuals. The results of these tests are essential to identify the characteristics of countries that are under study as well as possible methodologies that will be applied.
The results of the PARDL model indicated that in the short and long run, the impact and the elasticity of variable economic growth and trade openness are statistically significant at the 1% level, and thus both contribute to the consumption of energy from non-renewable sources. Nevertheless, the impact and the elasticity of the variable consumption of renewable energy is statistically significant at the 1% and 5% levels and thus contribute to a decrease in the consumption of fossil fuels in the LAC region. The PNARDL that verifies the robustness of the PARDL model indicates the same results. Additionally, PNARDL also points towards the impact of the variable renewable energy consumption and the elasticity of economic growth having asymmetric nonlinearity. That is, the results of PARDL and PNARDL confirmed that trade openness increases the consumption of non-renewable energy.
Therefore, the positive impact of trade openness on the consumption of fossil fuels indicates that the process of globalisation by trade liberalisation in LAC countries is not sufficient to attract more investment, capable of encouraging R&D in energy efficiency technologies, and in equipment that reduces the consumption of energy from non-renewable energy sources by households and firms.
In order to reverse the increase in consumption of fossil fuels, LAC countries need to create mechanisms to diversify the nature of their exports and imports, aiming at the acquisition and development of new products, with higher technological intensity, capable of enhancing the production of renewable energy and reducing the consumption of non-renewables. As Gozgor and Can (2017) defended, diversification of exports and imports encourages the acquisition of new technologies. Also Shahbaz et al. (2014) considered that trade openness is a source for the transfer of advanced technologies, for example, energy-efficient technology from developed countries to developing ones. Thus, the LAC countries should import more energy-efficient technologies from developed economies in order to reduce their energy consumption. However, this will not be possible if LAC countries develop mechanisms, such as new tariff and non-tariff barriers on products and technologies that improve energy efficiency. Indeed, energyefficiency product standards and labelling are policy mechanisms that impact the consumption of fossil fuels. This mechanism according to Ghani (2012), is a valuable policy tool to encourage the improvement of energy efficiency and the energy-efficient product standards during the trade liberalisation process.
Additionally, the increase of energy efficiency (in buildings, systems related to the infrastructure, transport, and in sections of production) is a priority of the LAC governments that can not be undermined.
Other mechanisms should be implemented in the LAC countries due to their characteristics, such as the decentralisation of energy production that improves the performance of the system, and the design of more public policies aimed at motivating the everyday use of zero-emissions systems and technologies (e.g., renewable energy technologies).
