This 2010 edition of Energy Technology Perspectives examines the extent to which an energy technology revolution is taking place, the key technologies that are emerging, the costs and benefits of these technologies, and policies needed to foster their use. ETP 2010 presents updated scenarios from the present to 2050 that show which new technologies will be most important in key sectors and in different regions of the world. It highlights the importance of finance to achieve change, examines the implications of the scenarios for energy security and looks at how to accelerate the deployment of low-carbon technologies in major developing countries. It presents roadmaps and transition pathways for spurring deployment of the most important clean technologies and for overcoming existing barriers. With extensive data, projections and analysis, Energy Technology Perspectives 2010 provides decision makers with the detailed information and insights needed to accelerate the switch to a more secure, low-carbon energy future.

As the world approaches the 2015 deadline for achieving the Millennium Development Goals (MDGs), which include a goal of reducing the proportion of hungry people by half, the 2010 Global Hunger Index (GHI) offers a useful multidimensional overview of global hunger. The 2010 GHI is the fifth in an annual series that records the state of global, regional, and national hunger. The 2010 GHI shows some improvement over the 1990 GHI, falling by almost one-quarter, but overall the index for hunger in the world remains at a level characterized as serious. The GHI captures three dimensions of hunger: insufficient availability of calories, shortfalls in the nutritional status of children, and child mortality. Accordingly, the Index includes the following three equally weighted indicators: the proportion of people who are undernourished, as estimated by the Food and Agriculture Organization of the United Nations (FAO); the prevalence of underweight in children under the age of five, as compiled by the World Health Organization (WHO); and the under-five mortality rate, as reported by the United Nations Children's Fund (UNICEF). The 2010 Index reflects data from 2003 to 2008, the most recent global data available on the three GHI components.
