Today we review a draft report prepared for the 2015 UN Climate Conference in Paris that provides an analysis of the ways that renewable energy source could be applied in 139 countries to replace the carbon sources currently used. Currently, only 3.8% of the power capacity is installed to reach 100% clean energy worldwide. In Canada, as an example, a power load of 412.1 gigawatts  is required by 2050 under a business as usual scenario . Under a clean energy scenario, however, the country would need only 240.2 gigawatts of power. Most of the energy would come from onshore and offshore wind (58%), utility-scale and rooftop solar (21%), hydropower (16.5 %) and a mix of other sources, including geothermal (2%) and wave energy. The avoided health costs would be $107.6B per year which represents 4% of GDP or 9,598 air pollution deaths avoided every year. The estimated total electricity, health and climate cost savings of this transition would amount to about $8,887 per Canadian per year (in 2013 dollars).
