> I'm exporting more than a megawatt per year back to grid for free

Do you take into account the energy needed to grow and transport the food you eat? To extract the material needed for objects you own? To build your car? To maintain the roads you use? I guess you obviously don't use fossil fuels at all and instead rely exclusively on the clean energy you produce?

Because if you don't, then you are still overall a consumer of energy.

But even if you were a net producer of clean energy, we as a society have a big problem of consuming too much overall. We will have to reduce that at some point (whether we want it or not). So it would be great if people started thinking about not eating meat for every meal, taking a plane every second week-end, and living in a sauna.

Again, I think that I'm doing better than the majority of the people and it makes zero sense for me personally to save several hundreds of kWt/hs per year (which I compensate through PV) while there are major industrial offenders around. Also I travel rarely but I can't work while on vegetarian diet.
