What renewable starts to produce more towards the winter to compensate for this especially since that's when energy consumption also rises?

Could it be possible to harness the weight of the snowfall, ice, or something else to power a turbine?

Luckily it’s summer in one hemisphere when it’s winter in the other. Unfortunately a global grid seems infeasible in the foreseeable future.

Yes, we then have to build wind turbines, plenty of under-utilised transmission (because wind is in the wrong place), methane CCGT/OCGT backup (and they need to receive capacity payments to keep them in business) and perhaps eventually electrolysers to convert excess electricity to H2 (which then have to operate at low utilisation). The overall system seems quite complicated and more complex than the first step of deploying cheap solar panels so save a bit of methane.
