Twisted bilayer graphene (TBG) at twist angles theta approximate to 1 degrees has recently attracted a great deal of interest for its rich transport phenomenology. We present a theoretical study of the local optical conductivity, plasmon spectra, and thermoelectric properties of TBG at different filling factors and twist angles theta. Our calculations are based on the electronic band structures obtained from a continuum model that has two tunable parameters u(0) and u(1) which parametrize the intrasublattice interlayer and intersublattice interlayer tunneling rate, respectively. In this article we focus on two key aspects: (i) we study the dependence of our results on the value of u(0), exploring the whole range 0
