Are we arguing? I thought we were talking 🤷 . Yes, but that also means that the rest of the time the energy has to come from somewhere. Like a coal power plant or similar. So this photovoltaic power plant is not a complete replacement for old power plant, but more like a partial one while still relying of fossil fuel, especially during winter and cloudy days.

    We typically use more power during the day (industry, mostly), so the solar helps us reduce carbon based infrastructure need even without batteries. And it's just a baby step in the progression to renewables. Yes, we have a long way to go.

    As all the world has. If we really want to prevent CO2 (and other bad) emissions, we need energy storage and a lot of it. Or nuclear. That said, these are steps (without proper energy storage) in right direction, but only as long as they replace energy from fossil fuel power plants.

    Sorry, I might have gotten a little defensive there.

    My point is if it supplements their energy consumption with cleaner energy it's a good thing.

    Even if its for a couple minutes or a couple hours its a positive improvement.

    No worries. It is, if it replaces fossil fuels. But it soon gets tricky if it is supposed to be a stable source of energy. For that we'd need awful lot of energy storage, probably in some form of batteries (sodium perhaps). Today it's relatively easy to slap solar panels everywhere, but it's not that easy to provide energy outside of daylight.

    Yes we need to go further but, sometimes it feels like we make perfect the enemy of progress.

    I'd love to see a large public works project that aims to increase the energy storage capacity/development across the world.

    I don't feel like we get there by focusing on it not being a complete solution.
