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.
