I assume those "grey" costs would also apply for any other energy source. You always need some kind of plant where you eventually produce and distribute the electricity.
- illys 7y agoYes I agree, and it should be counted everywhere.
- strainer 7y agoIts actually very complicated matter to count [1]. But if you look into winds "carbon footprint" you should find it is widely regarded as having one of the lowest overall emissions, about 1-2% of natural gas generations footprint.

- mrpopo 7y agoWhat you are talking about is called "Life cycle inventory analysis" of and is of course counted in the carbon footprint of a given technology, yes. Manufacturing energy costs are especially important for solar, which requires important amounts of energy for silicon purification and "monocrystallinization" (there must be a more adequate word). Wind power manufacturing costs are on par with other technologies.
