We'd be better ditching LEDs and switching back to incandescents, it would be far better for the environment.
All our power comes from renewables and nuclear, to a rough approximation, so if you're turning wind and rain or really excited neutrons into electricity you're not emitting things that change the climate. Converting that into a lot of heat along with light isn't worse for the environment than converting into not a lot of head and light, even if it means using more electricity.
What about the lamps themselves?
An LED lightbulb is a technological marvel made of a bunch of different plastics, fibreglass, copper, bismuth and tin for the solder, gallium arsenide in the LEDs, tantalum in the capacitors, assembled in huge factories using processes involving all sorts of hideous chemicals and a terrifying amount of energy.
On the other hand, an incandescent lightbulb is a milk bottle with a coil of wire in it and all the air sucked out.
Again, to a very rough approximation, something you can make in a blacksmith's forge is probably going to be better overall for the environment than something that requires a multi-billion pound factory.
Go renewable, and go incandescent.

- Gordonjcp 4y ago> When this happens, you might have a point. 98% of the energy here comes from renewables. The 2% that doesn't comes from nuclear, with fossil fuels providing something like 1/50th of a percent. Why are you all so far behind?
- pjc50 4y agoThis is an argument with no numbers in based on the idea that metals are scary and a bunch of scare words. > huge factories using processes involving all sorts of hideous chemicals and a terrifying amount of energy. As opposed to lightbulbs, which are all handcrafted by artisans using no chemicals or energy?

- thraway3837 4y agoEVs are bad too right? That use all these chemicals and materials and stuff that’s bad right?
- Gordonjcp 4y agoNew cars in general are bad. We already have enough cars, we don't need to make more.
- macondo 4y agoNot to mention the color spectrum is much more akin to natural light. I've never liked LEDS even high-CRI ones and will continue to buy incandescents. Also they work pretty decent as heating in the winter. A whole sort of subtle health effects are related to light.
