Those 3 things are more than 90% of us water demand. If people could cut their power bills by 30%, stop eating meat and conserve water
Electricity usage is largely inelastic without structural changes. 60% of our electricity is lost in transmission, for instance. Individual consumption habits won't change that.
An enormous amount of our meat production ends up as waste. Again, just telling random people to become vegetarian doesn't change this, unless the participants are concentrated enough to reshape how meat is produced and delivered. Even then, the US exports of meat range from 10% (beef) to 30% (pork) of gross production, with plenty of room to rise. Trade barriers, ecological limits, and land use policy go vastly farther to curbing animal methane emissions than politely asking people to stop eating meat.
And water is even less elastic than electricity. Municipal pipe leaks in your neighborhood will have a bigger impact on your street's water consumption rate than any amount of conservation or efficiency within the home.
You're fooling yourself if you think you have any influence on the macro scale through consumer habits. You're missing a forest of waste and misallocation of resources out of a personalized guilt trip.
My point is that about 2/3 of water usage in the US is to provide food, electricity and water to the 99%.
That's a fully made up statistic even before the advent of superusers like the AI farms. You're straight up ignoring our enormous agricultural export markets, our municipal waste, and the impact of major pollutants.
