[en] Rural electrification is considered to be a key strategy for poverty alleviation and sustainable development. It should therefore include (1) expanding electricity access and (2) enable new consumers to increase their electricity consumption. In this paper we ask how Brazil’s recent rural electrification efforts have managed to reach these objectives. A new method to measure energy and income equity is presented which uses estimations of non-parametric density curves for the analysis of energy and income distributional trends following electrification. By applying our method to a panel data set from two Brazilian states situated in the country’s poor northeast region we find that (1) rural consumers take up electricity consumption after electrification, and that (2) low consumption levels give way to higher electricity consumption levels after only a few years. This indicates immediate social benefits for households through consumption of electricity services. However, our analysis cannot verify a direct link between electricity use and rural income generation in the short term. The results emphasize the need for government and other actors to integrate rural electrification into broader rural development strategies in order to enable long-term welfare increases through electricity use. - Highlights: ► Comprehensive analysis of Brazil’s recent rural electrification efforts. ► New methodology to analyze energy and income equity trends ex post electrification. ► Analysis indicates immediate social benefits for electrified households. ► We cannot establish a direct link between electricity use and income in the short-run. ► Electrification thus should be integrated in long-term rural development strategies.
[en] This paper analyses the impact of an energy efficiency program for light vehicles in Brazil on emissions of carbon dioxide (CO2), the main greenhouse gas in the atmosphere. Several energy efficiency programs for light vehicles around the world are reviewed. The cases of Japan and Europe were selected for presentation here given their status as current and future world leaders in the control of passenger vehicle fuel consumption. The launching of the National Climate Change Plan and the pressure on the Brazilian car industry due to the world financial crisis make it a good time for the Brazilian government to implement such a program, and its various benefits are highlighted in this study. Three scenarios are established for Brazil covering the 2000-2030 period: the first with no efficiency goals, the second with the Japanese goals applied with a 10 years delay, and the third, with the Japanese goals applied with no delay. The consequences of a vehicular efficiency program and its middle and long-term effects on the consumption of energy and the CO2 emissions are quantified and discussed. The simulation results indicate that efficiency goals may make an important contribution to reducing vehicular emissions and fuel consumption in Brazil, compared to a baseline scenario.
