Notes : Weighted Average cost of capital was set at 7.1 % for OECD and China , however for the rest of the World IRENA set the WACC at 10 %.

Governments usually takes steps to enable access to low cost of capital with macroeconomics policies dedicated to accelerate investment in renewable technologies . Different types of macroeconomics policies will permit to gain tax incentives or guarantee improving attractiveness of renewable energy . According to the exhibit 4 , we clearly underline the evolution of solar energy in the recent years with a levelized cost of energy appealing for most of the industrial actors .
On the other hand , project profitability is entirely related to the process of determining the cost of the energy system . With a low cost of energy , investment could obtain a better chance to be successful and profitable for investors due to the relationship between weighted average cost of capital and energy costs
Moreover , the levelized cost of energy also called LCOE shows a shift in the renewable energy market : solar PV has fallen by appoximately 60 % from 2010 to 2016 which underscore the attractiveness of solar PV . Hydropower and Geothermal energy stays at the top due to their low costs respectively evaluated at $ 0.051 and $ 0.064 per kwh , a small price that allow major industrial actors to stay competitive internationaly in terms of productivity and distribution of goods and services . However , we believe that solar PV can lead the renewable energy market due to the technological progress accomplished during the years . LCOE is a common indicator used to compare the average cost per kwh between different technologies but we can find it quite limited if we wish to analyze deeply project profitability regarding a future investment . That ’ s why new tools appeared to be more responsive to meet investment criteria , Lazard developed a tool to include the cost of storage which helps investors seeking to diversify their investment in renewable energy . This indicator also known as LCOS ( Levelized cost of storage ) study analyzes the levelized costs associated with the leading energy storage technologies given a single assumed capital structure and cost of capital , also including appropriate operational and cost assumptions . More simply , this indicator takes account of a wide range of costs such as operational and capital costs to define the real aveage price of each kwh produced by the technology , even the storage costs can be included to really underline energy storage role : its impact on the energy costs and the WACC of each project .
