Improving energy efficiency is all fine and dandy, but declining energy consumption is a sign of dying system. In _healthy_ systems energy freed by improving efficiency goes to other task, therefore gross energy consumption stays the same or growing. But do not worry, you're not alone here, that's worldwide trend more or less. Renewables as the form of new energy source is ultimately a dead end, in fact even what we have now in that field was to a great extent made possible by low oil energy costs assossiated with the full cycle from production to utilization. No cheap oil = no renewabels as a substantial source of energy. That's how human kind rolls, a neverending battle for increasing energy flow per capita. The task of a new source of energy aside from increasing the resource base is to dramatically increase that energy flow therefore ultimately change the quality of civilization. Natually renewables in that context are hardly an answer to our needs, and as much as non-convential oils, are merely delaying the inevitable, the decline. So do they worth investment? No.
