Forget eco-nonsense, reliable power is vital

-

CALIFORNIA leads the way to electricit­y blackouts, closely followed by South Australia.

They both created this problem by taxing, banning, delaying or demolishin­g reliable coal, nuclear, gas or hydro generators while subsidisin­g and promoting unreliable electricit­y from the sickly green twins – solar and wind. All supposed to solve a global warming crisis that exists only in academic computer models.

Energy policy should be driven by proven reliabilit­y, efficiency and cost, not by green politics.

Wind and solar will always be prone to blackouts for three reasons.

Firstly they are intermitte­nt, producing zero power when wind drops or sunlight fails.

Secondly, green energy is dilute so the collection area must be huge. Both solar panels and wind turbines are old technologi­es and now close to collecting the maximum energy from a given land area of wind and sun, so limited technology gains are possible. Wind turbines generate nothing from gentle breezes and must shut down in gales. To collect more energy the green twins must collect from greater areas using a widespread scatter of panels and towers connected by a fragile network of roads and transmissi­on lines. This expensive, extensive but flimsy system is far more susceptibl­e to damage from cyclones, hail, snow, lightning, bushfire, flood and sabotage than a big, well-built, centrally located, well-maintained traditiona­l power station. Green energy also requires far more

investment in transmissi­on lines and inter-connectors that consumers must pay for, and the energy transmissi­on losses are greater.

Thirdly, green energy is like a virus in a distributi­on network.

When the sun shines, solar energy floods the network, causing energy prices to plummet. Coal and gas plants are forced to operate at a cash loss or shut down. Erratic winds make this problem worse as they are less predictabl­e and changes can be quicker. But when all green energy fails suddenly, like in an evening peak demand period after a still cold sunset, coal cannot ramp up quickly unless it has been kept on standby with boilers hot, waiting for an opportunit­y to generate some positive cash flow. Gas and hydro can fire up swiftly but who wants an expensive fair-dinkum power station that operates intermitte­ntly?

When Danish windmills stand silent, they import hydro power from Scandinavi­a. When German solar panels are covered in snow, they import nuclear electricit­y from France. And California can draw power from Canada.

The looming Covid depression has no room for more green energy silliness. A hard dangerous new world is coming. To survive we will need cheap reliable energy – coal, gas, nuclear or hydro.
