The desert regions in China that are largely uninhabited are the Iner Mongolia region on the north of the country, and the Xinjiang region on the west of the country.
Saudi Arabia is a country that in most part is uninhibited and people are concentrated in the cities which are surrounded by desert and some partially from sea. The most uninhabited regions are Northern Borders, Jawf, Bahah and Najran.
I think it's the first one and the third one. Not completely sure though.
The sun's energy is made up of burning hydrogen and helium.
