Appendices1. Global Energy Consumptions by source: Source: International Energy Agency (IEA)The above figure demonstrate the need for more focus on renewable source of energy to matchthe demand. As seen above, it is apparent that the fossil fuels including coal, oil and natural gasare the dominant sources of energy in industrial economies. They are the main source of theproduction growth in energy in the developing economies. Figure 2: Availability of the Global Renewable Energy Source: Jacobson and Delucchi (2011)The above table illustrates the conclusion by a recent study that renewable energy sources,anchored on wind, water, alongside sunlight (WWW) might give all the new energy globally byyear 2030, and substitute all the present non-renewable sources by year 2050. The tabledemonstrates the estimates of the potential energy from a range of renewable energy sourcesafter conversion into the trillions of watts. The forecasted global energy in the year 2030 isseventeen trillion watts. Therefore, from the above table, it is observed that the energy

availability from wind and solar in probably-developable destinations is more than adequate tomeet all the energy needs of the world. Figure 3: Infrastructure requirement for supplying all global energy in 2030 from renewable sources Source: Jacobson and Delucchi (2011)The above table indicates the estimated desired infrastructure to supply all energy globally whenWWS in 2030. The table indicates the outcome, anchored on the assumption that ninety percentof global energy is supplied by wind alongside solar, and ten percent by other renewables. Thestudy further considered requirement for land for renewable energy infrastructure. This includedthe land for appropriate spacing between the wind turbines. The entire land required amounted tonearly two percent of the total global land area. Figure 4: Cost Comparison of Renewable Energy Sources to Fossil Fuel Electricity CostThe above figure has compared the cost of renewable energy with the traditional fossil fuelelectricity costs. The cost of renewable energy is made competitive by making their costs fall to
