1. ( to the post you are relying to) Energy losses at transmission voltages are not a huge driver for decentralization. The largest benefits are usually sub station upgrade deferrals and other capex/ demand (kW) driven reasons 2. The full life emmisions impacts of solar, wind, BESS are substantially lower than fossil fuel plants... . For example, solar is around 40 g/kWh( ~4x worse than wind but small scale wind has crap capacity factors so not applicable for a homeowner) over the life of a system and batteries are probably 100,000 g/kwh capacity. If you have a 10 kWh battery and use it every day for 10 years, that's around another 25 g/kWh. Thia puts you around 65 total g/kWh which compares favorably to ~400 for nat gas and ~ 800 plus for coal. These are pretty conservative estimates, but does compare favorably to the grid in most places (maybe not wind rich places). There are some concerns like cobalt mining practices for lithium ion batteries, however those are already being designed around... Sent from my SM-G960U using Tapatalk
