Power systems must be actively managed to maintain a steady balance between supply and demand. This is already a complex task as demand varies continually. But what happens when supply becomes more variable and less certain, as with some renewable sources of electricity like wind and solar PV that fluctuate with the weather? to what extent can the resources that help power systems cope with the challenge of variability in demand also be applied to variability of supply? How large are these resources? and what share of electricity supply from variable renewables can they make possible? There is no one-size-fits-all answer. the ways electricity is produced, transported and consumed around the world exhibit great diversity. Grids can cross borders, requiring co-ordinated international policy, or can be distinct within a single country or region. and whether found in dispatchable power plants, storage facilities, interconnections for trade or on the demand side, the flexible resource that ensures the provision of reliable power in the face of uncertainty likewise differs enormously. Written for decision makers, Harnessing Variable Renewables: a Guide to the Balancing Challenge sheds light on managing power systems with large shares of variable renewables. It presents a new, step-by-step approach developed by the IEA to assess the flexibility of power systems, which identifies the already present resources that could help meet the twin challenges of variability and uncertainty.

Globally, the number of conflicts is increasing which is the main cause of much of the recent deterioration of the global food security situation. This situation is exacerbated by climate related shocks. Since 2009, a combination of man-made and natural disasters has disrupted livelihoods, threatened food security and forcibly displaced millions of people in northeast Nigeria. The conflict, in northeast Nigeria, takes on a central role in the ongoing food crisis by severely curtailing the ability of populations to access land and other natural resources such as woodfuel, the central object of this analysis. Access to energy is a precondition to food security, both are often highly constrained during crises. The ways in which energy is produced and used, can aggravate the vulnerability of populations to a number of risks and challenges by exposing them to malnutrition and other health conditions, reduced resilience to natural hazards and to environmental degradation, a disproportionate work burden for women, protection risks, conflicts and unsustainable livelihood activities. FAO, UNHCR and WFP have been promoting the multi-sectoral Safe Access to Fuel and Energy approach (SAFE) in the context of forced displacement to support an effective response and to contribute to building the resilience of vulnerable populations. The starting point of such a response in northeast Nigeria is this woodfuel supply and energy demand assessment, which provides a baseline for designing comprehensive interventions that take into account the energy needs of affected populations. The desired outcome of the SAFE approach is to “satisfy the fuel and energy needs for cooking, heating, lighting, and powering in a safe and sustainable manner, without fear or risk to health, well-being, and personal security of crisis affected populations”. The SAFE approach could make an effective and significant contribution to improve food security and nutrition, and ensure the sustainable management of natural resources. In addition, it will positively affect livelihoods, women and youth empowerment, protection and health risks. By taking adequate climate change mitigation and adaptation measures, the SAFE approach will also help to increase the resilience of vulnerable populations in the face of natural hazards and disasters, and contribute to peaceful coexistence between IDPs and local communities.

Climate change poses many challenges that affect society and the natural world. With these challenges, however, come opportunities to respond. By taking steps to adapt to and mitigate climate change, the risks to society and the impacts of continued climate change can be lessened. The National Climate Assessment, coordinated by the U.S. Global Change Research Program, is a mandated report intended to inform response decisions. Required to be developed every four years, these reports provide the most comprehensive and up-to-date evaluation of climate change impacts available for the United States, making them a unique and important climate change document. The draft Fourth National Climate Assessment (NCA4) report reviewed here addresses a wide range of topics of high importance to the United States and society more broadly, extending from human health and community well-being, to the built environment, to businesses and economies, to ecosystems and natural resources. This report evaluates the draft NCA4 to determine if it meets the requirements of the federal mandate, whether it provides accurate information grounded in the scientific literature, and whether it effectively communicates climate science, impacts, and responses for general audiences including the public, decision makers, and other stakeholders.

Over the coming decades, the supply of electric power will need to expand to meet the growing demand for electricity, but how the production and use of electricity develops will have broad ramifications for the diverse economies and societies of Latin America and the Caribbean. This report discusses the critical issues for the power sector considering a baseline scenario to 2030 for countries and sub-regions. Among these critical issues are the demand for electricity, the total new supply of electric generating capacity needed, the technology and fuel mix of the generating capacity, and the CO2 emissions of the sector. Under modest GDP growth assumptions, the demand for electricity in Latin America and the Caribbean would more than double by 2030. The analysis suggests that under any economic scenario, it will be challenging for the Region to meet future electricity demand. The report shows that meeting the demand for electricity in Latin America and the Caribbean can be achieved by not only building new generating capacity by the expansion of hydropower and natural gas, but by relying on an increased supply of non-hydro renewables, expanding electricity trade, and making use of supply and demand-side energy efficiency to lower the overall demand for electricity. Some recommendations derived from the report are the need for strengthening regulations and market design of hydropower and gas power generation projects and the need to design supportive policies to develop renewable energy technologies and promote energy efficiency measures. The primary audience to which this report is addressed are policy makers, power sector planners and stakeholders.
