Cold Fusion is dead. It has no basis in scientific study anymore. No theories have produced even a modicum of results in the field, and it doesn't look like we'll ever see any. It is already in the heap of failed theories for 99.99% of theoretical physicists. Hot fusion is doable, but we are still at least 15 years away from it even being done correctly at the ITER plant in France. Even then if it succeeds, we probably won't see mass production of the ITER reactor until we're almost dead.

Our best hope right now to relieve the environment of its woes is cheap, well made fission reactors in combination with solar panels all over the fucking place. GE and several other companies already have tons of very solid reactors they are able to market to anybody that has the money and the patients to deal with the government. We really haven't built any new reactors since the 70's, and the government makes it extremely difficult to do so. This needs to change if we're to make any sort of progress. Wind power and solar are not enough by themselves to help us now.
