Not at this scale and price and convenience.

We can absolutely do so for higher prices. And with solar panels becoming more efficient, cheaper, and more ubiquitous with each passing year, we may find that a lot of those "higher prices" were really just "higher energy input costs", and we will be able to come very close to what we have now. (I don't know for sure—this isn't an area I keep abreast of.)
