Whale blubber. Or nuclear fusion power. We still have a lot of fossil fuels to use, especially coal. If the test fusion reactor in France goes on line to schedule, we should see the first fusion power plants within 50-70 years, long before we run out of coal.

We will likely have to rely on a variety of sources. Nuclear fission will be big for some time, but uranium is a limited resource as well. Fusion from hydrogen could keep us going thousands or even millions of years, but so far we haven't been able to make it work and there's no promise that we can.

Solar is one of the most promising technologies that we have presently working. We cannot yet acheive the efficiency to maintain our civilization or way of life, but we're working on it.

Hydrogen fuel cells are not an energy source. They are a means (in combination w. stored hydrogen) of storing energy. They are limited at the moment by our problems in safely storing hydrogen gas.

Biofuels will likely play a large role in the future. How large a role depends on how well we can get fuel cells and batteries to work (somethings got to move our trucks and cars). It also depends on how seriously we take global warming.

p.s. It should be noted that fossil fuels will likely never disappear. As they are used up, the prices will rise and we will be forced to look to other means for economic reasons long before we run out.

The main energy sources can be solar, nuclear, tidal, etc.

Based on current data, nuclear energy is the second most popular source, and is reliable and safe.

However, comparitively "inferior" fossil fuels (e.g. compressed natural gas) will replace traditional fossil fuels before true alternative sources become commonplace.

My vote is on treadmills, but you must consider two other possibilities. You see, your question assumes that "all things will continue going on as they have from the beginning." But this society of quick, fuel-enabled transportation is only 100 years old.
One possibility is no more cheap energy and we quit zipping back and forth. We, instead, settle down to how humans lived for millennia before the automobile: walk, donkey or horse for the rich, and we learn to wait for just about everything.
The other possibility is one of these many nutcase groups starts the next world war (I have read that there are some groups who are counting on it!) That said, the "postwar" society is a dice throw, even if there is one, because it will be considerably more destructive (thanks to better technology) than the first two combined.

But then, in the meantime, folks are working on both oil shale and oil sands, of which there are zillions of barrels, as well as alternative ways to generate electricity.

With coal reserves over one hundred years and vast untapped reserves of tar sands and methane hydrates, there is greater suitable than adequate fossil gas to fully ruin the ambience for human use before we run out. we could have the capacity to fulfill the flexibility desires of a complicated society of 10 -12 billion people a century from now with the aid of a mixture of a few fossil gas use, renewable fuels, photograph voltaic and different selections like wind and tidal, nuclear and notably greater conservative use of power. photograph voltaic and performance technologies supply the main earnings for greenback spent. the expenditures of cleansing up the residues from our present equipment and the long term residual injury performed would be decrease the faster we commence on the transition.

We won't need any.

The US and UK are already busy culling the population in Iraq (3,000 a week at present), Afghanistan and anywhere else they can lay their hands on. And this is when we are just half way through world oil reserves.

So by the time we really start to run out, they will be busy killing almost everyone to make the rest go round.

Isn't war convenient.

Nuclear fusion, if the can get it to work..........lol
Hydrogen power cells.
And whatever the oil companies have hidden away for a rainy day!
