Solar power, for example, is not renewable.  Once it is all used up, it will not "renew" itself -- and this "using up" process is quite independent of our usage of it, as it happens.  The time to depletion may be somewhat long, but it still has a time to depletion.  Oil and Gas, however, is a "renewable" resource and as a mere physical and chemical process it is occurring at this very moment.

Well, the sun can't be "used up". You just have to wait 12hrs - 15hrs 
before you can see it again :-).

Seriously, though, solar != storage. You can have solar (power) without 
storage. It's not very useful when you have a grid outage, or on days 
with low irradiation, but for what it's worth, it will do its thing.

Renewables is not about lasting forever, but about lasting for as long 
as they can with minimal impact to the environment. Economically and/or 

Having spent some time on this, for me, it's about comfort, and quality 
of life. If you look at renewables as pure cost-benefit analysis (to the 
Economics majors, that's RoI), you'll be sorely disappointed.
