High ceiling and large plentiful windows also increase the heating need. Should you want to reduce you energy consumption, you have to reach a balance. Within that balance light is pretty low in any energy budget. In France it's 10% of the electricity consumed by people. Energy consumption for heat can also be solved by thicker walls and better insulation, but how are those walls and insulation produced? Are we talking about energy or carbon reduction? It's tough to analyze the whole chain. Burning wood is carbon-neutral, but can be carcinogenic when not fully efficient, and transporting wood can generate carbon... What I'm getting to is that it's a complex system, and among that system, pollution due to light generation is really, really, really low at the bottom of the priority list. |
