Our grandfathers built a low-cost reliable decentralized electricity supply for all states of Australia based mainly on black and brown coalfields — Blair Athol, Callide, Ipswich, Sydney/Newcastle, Yallourn, Leigh Creek, and Collie.

Then our fathers built the mighty Snowy Mountains Hydro-Electric scheme, which provided water to irrigate the inland while generating electricity to help pay for it.

In the years up to 1980, huge new coal-fired power plants were constructed in each state.  We discovered oil and gas in Roma, Bass Strait, Barrow Island, Timor Sea, and in coal and shale in many places.

Coal and hydro gave Australia reliable low-cost electricity that was the envy of the world and supported primary, secondary, and tertiary industries.

We irrigated crops; electrified cities; powered railways and mines; refined metals and petroleum; and processed milk, wool, cotton, grains, meat, and fruit.  Factories made Victa mowers, Southern Cross windmills, and diesel engines.  Holden, Ford, Toyota, and Mitsubishi all produced cars in Australia, and we made nine brands of tractors.  The Ipswich railway workshops produced locomotives and rolling stock, and Lithgow produced small arms.  We canned Golden Circle pineapples, Ardmona stone fruits, and Rosella jams and made Bully Beef, tomato sauce, and Vegemite.

Australia once valued decentralization, and it served us well in electricity supply.  Electricity generation and distribution was left in the hands of state-based engineers and entrepreneurs, and competitive state governments strove to ensure that their states had the most reliable low-cost electricity.  In those days, a state "co-ordinator general" was charged with predicting demand for electricity and then ensuring that power stations were built in the right place at the right time.  The distant federal government largely confined itself to defense, foreign affairs, immigration, and quarantine (with increasing meddling into wage-setting, welfare, and devaluation of the currency).

All that changed with the U.N.-initiated climate war on coal and gas, which drove a campaign of tax-delay-and-destroy hydrocarbon energy.

Canberra became the epicenter of the zero-emissions religion, and energy management and policy became centralized.  Green energy was mollycoddled with subsidies, mandates, and propaganda, and electricity supply was polluted by a rash of intermittent wind and solar plants with no backups.  These caused such variability and unreliability in electricity supply that the successful state-based decentralized electricity networks were replaced by a costly interconnected Eastern States grid.  Transmission costs rose sharply because of guaranteed returns on inflated capital for interstate, undersea, and the scattered wind-solar connections.  Electricity costs soared, reliability suffered, and Australian industry closed or moved to Asia.

There is only one way out of this mess: we must retrace the way we got in.

Firstly, any operator wishing to connect to the grid must demonstrate its ability to supply 24/7 power with its own generators, batteries, standby generators, or contractual arrangements.  Businesses, towns, and communities should be free to operate "off-grid" at their own cost and risk.

Secondly, Canberra must withdraw from electricity taxation, subsidies, regulation, and control.  This means no "Renewable" Energy Targets, no "Clean" Energy Targets, no Paris Accord, no emissions targets, no carbon taxes, no subsidies or mandates for wind/solar energy or batteries, and abolition of all federal prohibitions on nuclear power.  States that shut or destroy their coal/gas generators must live with the consequences.  The states must take back responsibility for all regulations imposed on electricity supply, with goals to maximize reliability and minimize costs.  They will see the results as residents and businesses migrate to states with low-cost reliable energy.

The interstate electricity grid is of value and should be retained but removed from federal management and control.  Its inflated capital should be written down greatly, and states and private operators should own and control it, with a regulator setting maximum transmission charges.  Europe copes with several countries buying and selling electricity across borders — surely, Australian states can do the same?  (The Australian interstate highway system is largely state-owned but copes with public roads, toll roads, urban roads, local roads, and private roads of greatly varying quality and capacity.)

And, if Canberra truly believes the "Zero Emissions" mantra chanted by rowdy schoolkids, let's use ACT as a pilot plant and insist that all ACT homes and businesses live without subsidies from taxpayers or consumers and without generating or importing any energy from coal, diesel, petrol or gas.
