Research has been yielding some pretty promising results lately in the battery department, so there is hope there.

Fission requires an enormous upfront costs, but the yield ratio is better than anything we’re doing right now. The biggest problems with fission are the waste and public perception (the nookular crowd), the last being why no major projects have been brought forth recently. Hopefully we are able to figure out fusion soon; there’s been some great strides made in that too, but we are still quite a ways off from it being commercially viable.
