The oceans and seas have huge areas of the planet. The ecosystem services that can be obtained from these resources are very diverse and with potential one of these sources is wind power. As a result, the Caspian Sea is widespread with a fragile ecosystem. Which seems to be the right choice for the development of this industry. Therefore, for modeling the wind energy of the Caspian Sea, the data from the ERA-Intrem for 1980 to 2015 combined with QuickScat and RapidScat remote sensing data. The modeling results showed a power density of 173 W/m2, concentration density in the series process showed that 67% of the Caspian Sea area has a decreasing trend, the rate of this sea change for the entire period from 1980 to 2015 was 2.1 W/m2. These changes in the northern part of the Caspian Sea have a higher rate than other parts. The sea is affected by climate change.
