LEAP (Long-range Energy Alternatives Planning System) is a simulation model, which is essentially an energy-environmental model based on stages, and examines the implications of a stage that allows indicating the implications of the stages related with "what if" question.
Two stages were generated by LEAP; using 2012 as a base year and 2020 as a future year. The first stage, called "Reference Stage", examines the likely changes of energy consumption patterns for the following years no considering new policies and a second policy stage, called "Stage: Introduction to Improved stoves", which examines how to reduce the growth in energy consumption through the introduction of energy efficiency measures in biomass consumption of an improved stove and traditional stove in Bolivia’s householders over the time. In this new policy stage, defining future goals which wanted to get terms of demand / consumption of energy, is incorporated improved stoves with 50%, with the dissemination of stoves is intended to strengthen the National market of improved stoves sustainably, this stage allowed us to examine how to reduce the consumption of biomass like fuel for cooking in rural area, replacing traditional stoves by improved stoves.
In the chart below we can see that the final energy demand for fuel is decreasing especially for biomass and dung that due to the introduction of improved stoves and reduced the percentage of rural households will have had until 2020. The biomass energetic demand in the reference stage is 3.4 BEP by 2020, but considering the policy stage: Introduction of improved stoves, the energy demand is 2.5 BEP, less.
