When I entered Istanbul Turkey for the location (no specific street address) the service automatically applied the default location: Halaskar Gazi Caddesi 224A, Istanbul Turkey 34384, and used the weather station 1244217. I was able to get results for both electric and fuel.
Based upon your screenshot the third-party service that we use for CO2 emissions data (CARMA) did not provide us with data for a power plant for your location--thus you are seeing "NA" for all of the Carbon data on the right side of the screen. That data is required so that we know how to calculate the CO2 emissions from electricity use in your building. The sources supplying the electric plant impact the CO2 emissions impact the CO2 emissions for the electricity usage for your project. For example a large percentage of fossil fuels versus renewable energy used by the power plant will mean each kilowatt of electricity used in your building will emit more CO2 than if the power plant used less fossil fuel and more renewable energy.
If in the past you were able to get results for your location it's possible the CARMA web service was temporarily unavailable.
I hope this helps explain it. Let us know if you have more questions on this topic, otherwise please accept as a solution so that others can benefit from this information.
