can we create wind and solar panels just from wind and solar panels (('s energy))

PV (solar cells) : EROIs (Energy return on investment) between 8.7 and 34.2 were found … meaning : yes ! … they create much more energy than the energy needed for their production.
it’s all in here (also for wind thingy😋) en.m.wikipedia.org/…/Energy_return_on_investment
