In our second session we looked at what was needed to achieve a net zero carbon energy system for Australia. We compared two approaches from advocates to 'electrify everything' on the understanding we will eventually achieve carbon-neutral electricity production. The first was a bottom up (household up) approach proposed by Rewiring Australia and the second was a top-down approach proposed by the Clean Energy Council. We then considered these pathways with the Federal government's policy it took to the last election. We found that the new government's policy generally matched the primary the steps each of the advocates propose.
