What would the earth be like if it didn't rotate, and only have on side of the planet facing the sun all the time?

Your question is misleading.  
Either the Earth doesn't rotate at all and the side exposed to sunlight changes during a year.  
Or  
The Earth and the Sun are gravitationally locked, and only one side of the planet will be facing the sun at all times.
