You should check out Hans Rosling's lectures [1]. Statistics points towards the fact that as people become more wealthy, they have less children. It should stagnate around 11 million people by most models.
Per capita energy usage is about 6 MWh / year and our population has been doubling every 53 years. Assuming that continues, in 10000 years we'll be using 4e69 Wh / year. If we figure out 100% conversion of mass to energy, that's 1e56 kg of fuel, which is a lot more than all the matter in the visible universe.
You can play with these numbers a little, but even reducing the energy usage per person by a million only gives us another 1000 years. Soon we'll be growing so fast that every year we'll use all the resources within one light-year.
