The use of renewable energy resources, especially solar and wind are increasing remarkably within most power grids in the world. There has been immense growth in the installed renewable energy generation capacity last two years. Most developing countries are gradually planning to add significant amounts of renewable power to their electricity grids. Additionally, the cost to generate electricity energy from solar and wind has remarkably declined in last years. The aim of this study is to investigate the effect of the progress and cost decreases in wind and solar technologies on the amount of installed power in the grids. This study evaluates wind and solar power projects in terms of engineering economics and provides experience gained from global investment projects.
