Your bills keep going up as you're paying for two sets of generating infrastructure and the crazy schemes to balance production and demand...
Wind and Solar are unreliable, when working at full output they can produce enough to meet a good proportion of demand.... but the sun don't shine at night and the wind doesn't always blow so you need enough nuclear and gas stations to be able to meet the same demand when it's dark and calm. We don't actually have enough capacity so we have to import from various sources in mainland europe often at exorbitant cost.
Batteries - don't even go there.... just don't have the capacity to be able to keep the grid running for any period of time. The larger battery implementations in the US have a nasty history of fires and the locals in California are getting fed up with them : https://ctif.org/news/bess-fires-residents-sue-energy-companies-after-massive-toxic-battery-fire-moss-landing-power#:~:text=Monterey County%2C CA – Following a massive lithium-ion,of failing to maintain adequate fire safety measures.
Keep an eye on https://gridwatch.co.uk/ to see how often the renewables/unreliables aren't producing what's needed.
