Yes,
We are selling coal to China, so they can burn it there, generate cheap electricity to make cheap solar cells they then send over here.
So we can feel warm and fuzzy about helping the Earth and climate change.

Solar cells are barely net energy producer, but the energy used to make them is a coal energy burned in China, while we make “clean” electrical energy from them over here.
Guess what, the CO2 released in China is the same as the one we could release here.

“Solar cells are barely net energy producer, but the energy used to make them is a coal energy burned in China, while we make “clean” electrical energy from them over here.”

The first part of your statement is false solar panels of typical polysilicone construction pay back their EROI in four years or less. Can you provide a reference for an negative or even slightly positive EROI on any modern panel made this century? If so please do.

You are right about China using coal electricity to refine silicon into cells for panels. Humans should do that while.we have the resources to make the inevitable transition to forever energy sources. As I tell my students and what was told to me by my mining industry mentors. Mine once use many. Silicon is recyclable as is aluminum ,boron and phosphorus the four primary ingredients to modern polysi cells.

Here is the official EROI of solar panels on residential rooftops.
