short answer: once
Solar panels (PV) degrade over time and use and have to be replaced and disposed of. A better case would be for things like solar furnaces that are simpler, but most of the time solar implies PV panels.
Wow, solar panels that last forever? That's quite the technological achievement...
This is the dumbest fucking argument. I’m sorry but what point do you think you’re making?
Is it imperfect? Yes. Just like ALL OTHER THINGS. Is it a major improvement compared to burning coal? OBVIOUSLY YES.
The obvious answer is to live in a yurt, drink rain water, and never use electricity again that you don't make from a bicycle-powered generator.
What's the yurt made of?
Fallen branches, leaves, and trees not already needed for any animal habitats or nutrition. The string to hold it together is, of course, woven from your own hair.
Also, no fires, since burning wood releases carbon into the atmosphere, so warmth can only be generated by sewing together carcasses of animals who died natural deaths.
And finally, following a strict diet to minimize gastro-intestinal discomfort lest you release methane into the atmosphere.
Or just make a rope from your own hair and hang yourself with it, as that's honestly the only way you can make no impact on the environment. I mean, don't do this, obviously, but that's it. As long as we exist, we affect the environment, so we should just do what we can to mitigate the negative effects. The perfect is the the enemy of the good.
^ this guy carbon neutrals
Its not an argument, its a joke.
You must see enemies around every corner... I'd recommend talking to a therapist about that.
I would, but they're all out to get me.
"Oh, your solution doesn't break the laws of physics? Trash it, we're gonna keep burning shit to make more shit we can burn forever until you have a magic solution or until we kill the planet"
The hundred year solution is nuclear. The thousand year solution is colonizing other planets.
Ultra dense energy has its place, namely where weight and volume are critical like in aerospace. Everything else can deal with not putting more carbon and worse things in the air.
You're taking an off-hand joke comment pretty seriously there, bud.
I'm a proponent of things like solar and nuclear, but having some kind of fantasy position of them being perfect technologies with no downsides whatsoever is a special kind of delusional.
You want to actually convince people of their benefits? Stop making up dream scenarios and provide realistic examples.
You can buy solar panels at Costco.
I can't help you with any more of a real world scenario. If you want to offset some dollar amount of your energy use with home-grown juice, that's the easiest way to get it done right now.
You can build a small amount of wind power from old car parts. If you don't have a Costco membership.
Solar panels lasting for decades here and now, that's close enough for all practical purposes. Solar has a proven track record, hydrogen technologies never made it past gospel.
