My H1b got stampped and will expire on 2017 .But unfortunately without any travel.Can I renew my H1B or it will be expired completely and became useless

An employer will have to file a cap-exempt petition for you, and you can get visa stamp renewed after that. This could be same as old H-1B employer or a new one.
