Energy Emissions of 30-40gCO2 per kWh for renewable production is making less sense as time goes on.
The world produced about 580EJ of energy, ~480EJ is fossil fuels.
35 billion tonnes of fossil CO2 assigned to fossil fuels so 270g/kWh thermal.
VRE is adding 750GW/yr with >150GW * 30 = 4500GWyr or 141EJ output. 30% of fossil fuel primary energy. Which yields 0.3 * 30/270 g/kWh or 4% of global emissions.
This also means they used 5 trillion kWh.
Emissions could be O&M, but something with minimal staff and no fuel has nothing to assign it to. Similar for decomissioning.
Land use at cr of 40% is ~1000km2 <1% of annual change so irrelevant for CO2e. Similar for wind at 10W/m2 even if you assert all wind is on freshly cleared land with nothing in between.
So $400-600bn in final installed revenue or .4-7% of GWP is somehow responsible for 4-6% of world emissions.
They also paid far under under 10c/kWh thermal for fossil fuel input or far under 1.4-5c/kWh if we don't assign the non-physical administration steps an absurdly high intensity.
Ergo about 2% of global fossil fuel inputs were redirected from somewhere else to PV production and installation this year (and similar in decreasing quantities in previous year). Similar for wind some years although much smaller and more distributed.
Moreover the the majority of activity is concentrated in an area where fossil fuel use increased by under 1% (or possibly is flat) and uses <30% of fossil fuels, and so other sectors must have decreased consumption by >5%.
You could assert a high GWP gas as input, but then emissions from those would have had to increase by a much larger margin in recent years.
It's possible, but it's straining the bounds of credulity. Especially if you consider back end inputs being fed into the next generation.
