The gravitational energy you put into a vehicle climbing a hill, comes back to you on the downhill side. The effect of weight is often overestimated for this reason. Battery power is very efficient, in terms of how much you put in, is close to what you get out, unlike with fossil fuels which are inordinately wasteful. Not to mention the general filthy nature of it.
For some years now solar production is less costly than fossil fuel production. It just takes a long time for existing production to wear out and be retired. The sunk costs of building refineries is enormous and solar needs its basic infrastructure to be constructed up front. Real estate, substations, transmission and distribution lines, point of sale apparatus, and so on. These are what make adoption of renewables slow. However, new construction of solar and wind are less costly than new construction of fossil fuel based energy means.
