Name some of those problems please?

Meanwhile LCOE of wind/solar is challenging that of coal power and closing to nuclear. In 15-20 years it would be way lower.

Batteries suck? They are quite expensive, have low capacity and age too quickly. They are also difficult to recycle.

The biggest problem is that no system can withstand such huge alternations in amounts of generated power. Solar and wind energy isn't available 24/7 and generation can't be rapidly changed to compensate for changes in consumption.

A windless week in the winter will leave you without power.
