‘If 1.5m Germans have them there must be something in it’: how balcony solar is taking off
(www.theguardian.com)
Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
What are you talking about? Of course, energy that isn't used in the household is pushed back to the grid.
No, that’s not how it works in the general case. There are ways to setup a house to back power but it’s more complicated than just plugging it in.
Without proper safeties in place back flowing power to the grid becomes extremely dangerous for line technicians
On loss of power these inverters cut off within 20 ms or so. These are grid-tied, not insular (though with hacked firmware some of the models can be madeninsular-capable).
Do you know how these kits work? The whole point is that they're plug-and-play. If the feed back into the grid, they are not plug and play and will require coordination with your power company lest you accidentally kill someone because you're backfeeding into a line they turned off so they could work on it.
The kits have built-in measures to avoid backfeeding, or they would be illegal. Where I live, they've been deemed so unsafe, failsafe or not, that you're just not allowed to use them.
They cannot back feed when there is no grid power, yes. But they cannot differ between power used inside the house or outside the house. They can and will definitely push power back out to the grid as long as they detect grid power from other sources.

These kits absolutely can push power into the grid, usually with payment for the generation. Just because they may not be allowed where you live doesn't mean they don't exist.
