Energy means, well, energy. Finland still drives combustion vehicles (a lot of them, last I was there they drove some of the oldest cars in the EU on average due to high taxes for buying new ones) and probably mostly heat with energy not originating from the trio you mentioned.
I think you meant electricity, which is a great milestone on the way but not yet the destination.
Electricity used to be about 10% of a rich country's energy consumption, of late I think it's closer to 20% as some early adopters and new buildings have made the switch, but that still leaves 80% of your energy generated from oil and natural gas
Livestock make up 62% of the world’s mammal biomass; humans account for 34%; and wild mammals are just 4%.

And add to that the fact that cow flatulence is very rich in methane (much more potent greenhouse gas than CO2) because of poor diet in industrial agriculture.
