As countries generate more energy from renewable sources, that energy must become part of the power-system planning process. In 2004, investments in all forms of clean energy represented about 20 percent of total global investment in generation capacity. By 2011, that share had topped 40 percent. This paper explains the various reasons behind the push for renewable sources, chief among them being reducing climate-altering emissions. The paper answers the following questions giving a brief synopsis of each: What is the key challenge? What solutions are available? What are the key lessons learned. A few case studies are also used throughout to illustrate key points.en-USCC BY 3.0 IGOAPPROACHBIOMASSBORDER TRADEBOTTOM LINECAPACITY EXPANSIONCARBONCARBON EMISSIONSCLEAN ENERGYCLIMATEECONOMIC IMPACTSELECTRICAL POWERELECTRICITYELECTRICITY SYSTEMELECTRICITY TECHNOLOGYENERGY PLANNINGENERGY PRODUCTIONENERGY RESOURCESENERGY SOURCESENERGY SYSTEMSFEASIBILITYFOSSILFOSSIL FUELSFUELFUEL COSTSFUTURE DEMANDGENERATING CAPACITYGENERATIONGENERATION CAPACITYGENERATION EXPANSIONGENERATORSHYDRO POWERHYDROPOWERHYDROPOWER PLANTINVESTMENT PLANNINGLOAD PATTERNMAINTENANCE COSTSPEAK DEMANDPEAK DEMAND PERIODSPHOTOVOLTAICSPOWERPOWER GRIDPOWER PRODUCTIONPOWER SECTORPOWER SECTOR PLANNINGPOWER SOURCESPOWER SYSTEMPOWER SYSTEM PLANNINGPOWER SYSTEMSPPRENEWABLE ENERGYRENEWABLE ENERGY SOURCESRENEWABLE POWERRENEWABLE PRODUCTIONRENEWABLE RESOURCERENEWABLE RESOURCESRENEWABLE SOURCESRESERVE MARGINRESERVE REQUIREMENTSSIMULATIONSOLAR POWERSOLAR RESOURCESTHERMAL PLANTSTHERMAL POWERTHERMAL POWER PLANTSTHERMAL UNITUTILITIESWINDWIND BLOWSWIND ENERGYWIND GENERATIONWIND POWERWIND POWER GENERATIONWINDSBrief10.1596/21575
