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 $0.03/kWh. (Source: Valor, 2018)
The LCOE ($/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.

The IRENA report found that solar and onshore wind are the cheapest energy sources. It states that in 2017 wind turbine prices had an average cost of $0.06 per kWh, and at times dropped to $0.04 per kWh. At the same time, the cost of solar photovoltaic (PV) had fallen to $0.10 per kWh.
