What are the choices? Everyone will have to go renewable sooner or later because of global warming (and if you ignore global warming, you will still to do it, just bit more later, because fossil fuels will run out). It's relatively easy to put together a package of renewable sources to cover all energy needs anywhere. In terms of electricity, that's already done in EU - fossil fuels only cover ~30% of consumption now (31.6% in 2023 and falling by ~3% points per year), and will be 0% by 2035, that looks easy today and does not require any new invention nor even existing tech getting cheaper. We currently deploy quite a bit more renewable capacity than needed every year to make it work. As for all kinds of energy together, that's quite a bit harder and so far, we are not there, but it shouldn't take more than about 5 years to arrive to the necessary rates of deployment.
