The cost of LEDs is dropping rapidly, and the lifetime costs are already lower than Incandescent. At this point saying they cost "10x more" is no longer factual.
Livestock production, including the animals themselves, ARE a significant portion of human gas emissions and environmental impact, both methane and CO2. Livestock responsible for roughly 10-14% of our CO2 emissions, 35% of our methane, and 65% of the nitrous oxide. In addition they require tremendous amounts of land area and resources. In areas such as the plains, that land is already well adapted to grazers like cows. But of course, that isn't the only place we raise them. We force land into being productive, by siphoning water, by cutting down forests, and other geoengineering methods. Each pound of beef you eat took 500 gallons of water produce. The amount of food provided to cattle alone in this country could feed 800 million people. It takes more than 4 lbs of feed to make a pound of beat. Not to mention changes in water quality and riverbeds from changes in erosion patterns, and the ripple effect that has every critter along the way. And this isnt even touching pigs (even higher methane production) or chickens. (Oblig XKCD)
It's not about seeking power over you. We don't care about you. It has a little more to do with caring about the survival of the species as a whole. Humans aren't very tolerant of higher CO2 concentrations, or higher temperatures. We are still very dependent on the natural world, even if we have rudimentary methods of harnessing it to feed ourselves. And if nature collapses, so do we. But reducing our impact on the planet doesn't require reverting to the stoneage. Civilization can survive just fine. Nor does it require forcing behavior. A tremendous amount of change has already occurred and will continue to occur through simple market forces, as not everyone is as obstinate or blind as you. "OH I have to give up burning dead dinos to drive from my mcmansion to work".... cry me a river. All the free energy humanity could ever want lands on the planet's surface every hour. Transitioning from burning oil to harnessing just a fraction of the sun's power is only a burden if your paycheck depends on the oil industry.
