No, the two revolutions are a lot more similar than you think. The industrial revolution was fueled largely by the technology to harness huge quantities of fossil fuels to power modern machinery. The underlying supply of energy didn't change - those fossil fuel reserves had been built up over hundreds of millions of years, as we're now learning (to our chagrin) a hundred years later. What did change is our ability to extract that energy from the world around us. After the industrial revolution, we woke up and found out that we had previously been literally scratching the surface of the resources available to us on this planet.
Similarly, the Information revolution has been fueled by a huge increase in our ability to collect and process data. That's allowed new means of production that use existing resources in a much more efficient way. No, there's no new energy flowing into the system - but there wasn't with the Industrial Revolution either, we just figured out how to use energy that was previously believed to be useless.
There are theoretical limits to the amount of energy our planet can generate, but if you study physics you'll see that the amount of energy extracted by human beings is roughly 1/1000th of the energy available to us [1]. The limiting factor is our technology, not the raw resources in the environment.
People from the future will likely consider the industrial and information revolutions to be the same revolution, just like people today generally consider the agricultural revolution to be one event instead of its two separate stages.
We could say the industrial revolution ended in 1945 with the Manhattan project and the information revolution began in the 1940's with the Enigma code cracking so the timelines flow into each other, and, as you say, they both had the effect of releasing vast amounts of energy. The agricultural revolution began about 10,000 yrs ago independently in 5 or 10 places around the world with plant seed selection and animal husbandry, but in only two places, North China and Mesopotamia, did they make the separate step of transplanting it all on a large scale to a river valley, perhaps even thousands of years later. (I'm presuming here Egypt and the Indus Valley copied Mesopotamia.)
I suspect the real third big revolution will be inter-stellar travel in perhaps another 10,000 years.
