We need a revolution in Battery technology if we were to get rid of our dependence on fossil fuels.

  Batteries don't generate power, they only store it. We still need to get the power from somewhere, and for the foreseeable future, that will have to include fossil fuels.

    But fossil fuels do also solve the problem of storage due to their energy density. One reason you put gas into a gas tank is not only is that a source of energy, but it stores a lot of it in a small space. The tank is also just a cheap steel container that whose capacity doesn't diminish with number of refills. If you can replace that with a battery with all the same properties: cost, space, weight, durability and so on, that does have an impact. The energy for filling that battery can come from fossil fuels, but doesn't have to. We have hydro, wind and solar.
