Na, both are important in Art. I find it totally valid to equal skill with Art and also understand if you disagree on that, but saying that equaling them means you don’t “understand” Art is pretty harsh. After all, making you think or feel something is a skill in itself. A super detailed and close to reality picture of a frog makes me think quite a lot about the amount of time and work involved, lets me marvel at the Details and, well, skill of the artist.
Roughly 50% of germany is used as farmland. On 60% of the farmland crops to feed livestock are grown. On 20% of it crops for energyproduction (biofuel, biogas). If you take for example rapeseeds, used for biodiesel, you would harvest around 50 times as much energy with a pv-plant on the same area. You would need to install pv on 5-6% of the farmland to produce enough electric energy for all of germany for a year. Granted you also can provide the grid for it and enoguh storage.
