Although the BZE plan is not new, I thought it would be good to write about in case any of our readers haven’t heard about it. Here is my summary of the synopsis, of the Zero Carbon Australia 2020 Plan.
Climate scientists predict severe impacts from even the lowest estimates of global warming. Atmospheric CO2 already exceeds safe levels. The threat comes from dangerous ‘tipping point’ mechanisms such as melting of sub-artic permafrost, which can be triggered by excessive temperatures and would prevent us from returning to safe climate conditions.
To make an immediate transition, we can use only the solutions that are available to us today. The ZCA2020 Plan has specified the 100% renewable grid based on proven technologies that are already commercially available and that have already been demonstrated in large industries. With a combination of energy efficiency, fuel switching from gas and oil to electrified energy services, then using a combination of commercially available renewable energy technologies, Australia’s energy needs can be met with 100% renewables. Wind and Concentrating Solar Thermal (CST) with Molten Salt Storage are the two primary technologies used, with minimal contingency backup from biomass and existing hydro.
Implementing the proposed renewable infrastructure over a ten-year timescale would require a small percentage of Australia’s industrial capacity, in terms of resources and labour force. The required investment of $37 Billion/year is the equivalent of 3% of GDP.

In my own words - It is possible to transition to 100% renewable energy within 10 years with technology that exists today. It would cost 37 billion dollars, or 3% of GDP per annum. The challenges of a transition to renewable energy are social and political, not a technical or economic.
