How many times have you read something like this?
The shift to renewable energy is unstoppable and accelerating. The role for gas and coal will rapidly diminish until renewable technology is further advanced to ensure a ready and reliable supply of power.
Fact check.
Where in the world has that happened, apart from Norway, where they make a living by exporting oil, gas and herrings?
Mark Mills reports that the reduction in the contribution of hydrocarbons to worldwide total energy consumption has declined from about 86% to 84% over two decades.
This suggests that the shift has just about stopped, especially as many countries are getting back into coal (Germany) and are accelerating their consumption (China and the developing world.)
In Australia the retreat from coal has hardly progressed since the closure of Hazelwood in 2017. Apart from unscheduled outages the only permanent closure of coal capacity in five or six years is the phasing out of Liddell, to be complete in April.
When Hazelwood closed, AEMO warned that we were travelling with dangerously diminished spare capacity. Further reduction in coal and gas capacity could be catastrophic and that has been averted by heroic load shedding during critical periods (Jan 2019) and (largely invisible) deindustrialization.
Someone should make a list of major investments in energy-intensive industries that have gone elsewhere. How can any power-intensive industry be established here (short of massive subsidies) while the cost of power continues to increase as it is bound to do. Think about the cost of re-wiring the nation and the state of the energy market, and the Voices that put a spoke in the wheel of gas projects.
Penetration of wind and solar has increased, in line with installed capacity, as AEMO likes to record with a new tab on the Data Dashboard. aemo.com.au/en/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem but there is a world of difference between DISPLACING coal and REPLACING it.

The exit of coal is limited by the lowest level of output on nights with little or no wind, as a convoy travels at the speed of the slowest vessel, the water penetrates the levee at the lowest point, a chain is only as strong as the weakest link and stock get out of the yard through gaps even if the rest of the fence is built to the sky.
As long as periods with effectively zero solar and wind power persist, 100% backup from conventional power will still be required, assuming that we want security of supply. This means that we will have to keep burning coal until nuclear power is on deck.

Wind watching can be time-consuming and habit-forming.
Watch responsibly.
