In terms of clean energy in the world we can highlight the growth of solar and wind energy. As for price, they change a lot according to the politics of the country.

Speaking of my country, Brazil, in the last years there has been an exponential fall in values, we have:

Solar Energy: R$ 0.31/kWh or USD 0.096/kWh (Source: Enel, 2017)

Wind Energy: R$ 0.21/kWh or USD 0.068/kWh

In Abu Dhabi, Chile, Dubai, Mexico, Peru and Saudi Arabia, solar energy hit $0.03/kWh. (Source: Valor, 2018)

Thank you very much Mr. João Lucas de Souza Silva

The LCOE ($/kWh) depends on many factors such as the considered technologies, operation scenarios, and fluctuations in the economic and financial indicators. Below you will find some studies about the viability, and LCOE estimation in Egypt considering wind, and solar-PV systems. Below also you will find a techno-economic study of wind, solar-PV, and their hybrid for powering a standalone deferrable load in Croatia. Another study considers the economics of solar-PV systems in Mexico. In these studies, battery storage is not considered because they either focus on grid-connected systems, or off-grid systems supplying deferrable loads.

Thank you dear Mohamed for your answer

You are welcome

Hello Omar, LCOE from renewables are competitive to those of nuclear driven techs since investment costs are huge for nuclear power plants. However, source steadiness and capacity are significant factors on LCOE as well. As far as I know, geothermal energy provides the lowest LCOE (down to 1.8 US Cents/kWh). Wind and solar are improving but source intermittency are major problems bringing higher LCOE. Intermittentcy problem is solved by energy storage, however it may increase the LCOE by up to 40-70% based on the storage technology.

I recommend you better check electricity sales prices in countries. Any technology needs to be providing lower LCOE than the cost in your bill. It is otherwise not economically feasible. (except for off-grid areas such as islands)
