though coal is a major source of power its not the only source... now coal producing plants are being replaced with nuclear technology...also its better to have pollution at far off places where these power plants are situated than having it in the cities which are densely populated.... but the point you made on the availibility of power in only major cities india is true to the core... this is one of the reasons why cars like REVA failed miserably ....availibilty of charging sockets restrict the movement of these cars... i completely agree with you on the issue of the maximum speed offered by electric cars sold in india...
