the increase of electricity cost was because of 20 years of high subsidy of renewables. The 20 years are ending soon (1-2 years) for the first who got those subsidies in the year 2000. Gradually electricity cost should become cheaper again, as the subsidy has become low enough (maybe in 10-15 years).
Improvments in renewable technology should make renewable energy cost effective even without subsidy (at least the newer ones).
I would love to see any evidence that renewable energy is cost-effective on any relevant scale. The true cost of solar and wind both with regards to externalities and actual cost is much higher than the current politically and marketing driven claims.
The number of misleading claims when it comes to the current state of batteries the cost-effectiveness of wind and solar etc is staggering.
Don't forget calculating the price and consequences of ex CO2 of wind and solar does not include things like true cost of production (the entire vertical stack), decommission, the fact that it makes other energy types more expensive (like coal used ex at night when the sun don't shine), doesn't include the cost of digging for rare-earth materials etc.
Don't forget that solar and wind require huge areas to work because the density of wind and solar is so low compared to nuclear, oil or coal.
Sun and wind combined cover less than 1% of the worlds energy needs. The high percentages some claim like when Denmark claim 40% comes from wind are misleading as they only compare to electricity, only talks about the energy that's produced in the country (an excludes energy imported for ex when there is no wind)
There is so much disingenuous information out there it's quite astounding.
