Summary/Abstract

The Logarithmic Mean Divisia Index (LMDI) method of complete decomposition is used to examine the role of three factors (electricity production, electricity generation structure and energy intensity of electricity generation) affecting the evolution of CO2 emissions from electricity generation in seven countries. These seven countries together generated 58% of global electricity and they are responsible for more than two-thirds of global CO2 emissions from electricity generation in 2005. The analysis shows production effect as the major factor responsible for rise in CO2 emissions during the period 1990-2005. The generation structure effect also contributed in CO2 emissions increase, although at a slower rate. In contrary, the energy intensity effect is responsible for modest reduction in CO2 emissions during this period. Over the 2005-2030 period, production effect remains the key factor responsible for increase in emissions and energy intensity effect is responsible for decrease in emissions. Unlike in the past, generation structure effect contributes significant decrease in emissions. However, the degree of influence of these factors affecting changes in CO2 emissions vary from country to country. The analysis also shows that there is a potential of efficiency improvement of fossil-fuel-fired power plants and its associated co-benefits among these countries.

Summary/Abstract

Approximately 87% of Nepal's total final energy is consumed by households. This paper analyzes the patterns of household energy use and associated air pollutant emissions in Nepal based on LEAP framework for thirteen analytical regions and three end-uses. Four scenarios involving different growth paths for socio economic and energy system development through the year 2040 are considered. The study finds that household energy use is heterogeneous across the regions and biomass for cooking dominates the country's energy-mix. Households' CO2 emissions are less significant but their local indoor pollutant emissions will continue to rise in the future. To help strengthen government's commitment to the UN's sustainable energy for all initiative, this study devises an energy development index (EDI) to assess country's energy access and poverty across the regions. The results reveal that the current level of both energy access and energy poverty in the country is below the basic human needs and this situation will improve by little in next 30 years. The paper argues that to improve these situations require more coordinated and innovative plans and policies from the government. The paper suggests that greater emphasis will be needed in reducing dependence of biomass for cooking, promoting domestic alternative energy sources, scaling up biomass improved cookstoves programs and developing periodic regional level energy database.
