I don't think there is enough wood to replace coal, so we'd probably need some new gas turbines. Remember that you need to be prepared for at least a couple of days of roughly zero renewable generation every couple of years. In many locations you have significantly reduced generation every winter. So you need to have sufficient backup capability available. I don't think today's battery tech scales to that amount of storage, so you'll likely have to rely on hydrogen or methane.
