I am open to many things, but so far no one has been able to explain to me how we can meet the electricity demand in winter without coal, gas, and nuclear. Can anyone here?

The mix makes it. Not just solar, wind, tides, etc. Sun-rich countries can produce and sell hydrogen. This way, poor African countries could achieve prosperity.
We have many weeks in winter with almost 0 photovoltaics and 0 wind power, nationwide in Germany. Should [Biomasse] and [Wasserkraft] then save us? Additionally, there is increasing demand due to [eAuto] and [Wärmepumpe], which require significantly more electricity precisely in winter. That cannot work.

0 wind power, certainly not. There is wind at sea even in winter. And many weeks without wind on land also do not occur in winter.
I agree. Recently, there were reports that projects in the Middle East generate electricity for 1 to 2 ct/kWh. And what about the efficiency when we convert that into gas?
When EE gas is used as a power storage, the efficiency from electricity to electricity is between 30% and 44%. When EE gas is converted back to electricity in combined heat and power plants, overall efficiencies of 43% to 62% are achievable (including 45% heat share of the CHP).
Some voices also say that synthetic gas from renewable energies could become cheaper than natural gas in the medium term. But I don’t know where the devil is in the details. Presumably, the necessary plants are still just much too expensive.
