What incentive do I really have to use other bulbs? It depends on where you live. If you're next door to the Three Gorges Dam or the Itaipu Dam, perhaps your hydro power cost is insignificant. But for most of the world the cost of electricity (over the life of a bulb) to power a 40W incandescent bulb compared to a 10W LED bulb far exceeds the price difference between them.

That seems like hyperbole to me. At least according to the data i found after a fairly quick search. https://www.hydropower.org/maps/worldhydropowerstatistics https://www.hydropower.org/maps/worldhydropowerstatistics https://ourworldindata.org/renewable-energy https://ourworldindata.org/renewable-energy https://www.kfw.de/stories/environment/climate-change/interactive-world-map-renewable-energy/ https://www.kfw.de/stories/environment/climate-change/intera... https://www.weforum.org/agenda/2017/09/these-3-maps-show-whats-powering-the-world https://www.weforum.org/agenda/2017/09/these-3-maps-show-wha... https://www.globalpetrolprices.com/electricity_prices/ https://www.globalpetrolprices.com/electricity_prices/ https://en.m.wikipedia.org/wiki/Electricity_pricing#Price_comparison_across_countries https://en.m.wikipedia.org/wiki/Electricity_pricing#Price_co...

  The cost of electricity dominates bulb costs. Here's some quick approximate math. 40W incandescent, $1 cost, 1,000 hours life. 10W LED, $5 cost, 10,000 hours life. Electricity $0.12 per kWh, my cost is about USA average. In 10,000 hours of use, incandescent cost is $10 for bulbs, $48 for electricity. Total $58. In 10,000 hours of use, LED cost is $5 for bulb, $12 for electricity, Total $17. $17 is much less than $58. In reality a 40W equivalent LED would use closer to 8W than 10W, and would last longer than 10,000 hours, and costs less than $5, so the comparison result would be skewed even more toward LED. Now what happens if you live in Germany. Electricity is €0.31. Which is 3x what I'm paying. So now the electricity comparison is €124 for incandescent, €31 for LED.

    Ya know, i mentioned above, I don't like the light LED's produce. I notice the difference and for me the difference in price in the end is negligible I really don't understand this incessant need to convince people they should switch to different lightbulbs, when my choice in lightbulbs in no way impacts anyone else. I live in a place with 100% renewable power. As far as i'm concerned, the simplicity and lack of chemicals in the bulbs I choose, outweighs the potential energy savings as far as that goes. My choices come down to what I prefer and what I feel my impacts are based on those choices. I've thought it out and this is what I choose and I shall keep on doing so until I no longer can and the lobbying has forced incandescents entirely off the market.
