Consolidating All The New "Green" Grant & Rebate Programs

I don't know if anyone else feels the same as me, but I'm having a hard time keeping up with all the new information for home-buyers regarding Green Grants & Rebate Programs.

I know things vary from state to state, but which ones are universal?

I know there is a rebate for going all solar, as well as tank-less water heaters.

Does anyone know about what types of rebates are offered when you buy energy efficient appliances?

What about impact resistant, energy efficient windows and doors?

If everyone can share the information they have, I will put up another blog post consolidating it into one place.

Thanks to everyone in this Green Forum!!!!
