I suppose the best thing I did to reduce my carbon emission was to move to a bike friendly city 4 years ago. I biked every day since. If this is not very practical in your city then opt for collective modes of transport and lobby for a bike/walk friendly planning, at least at a neighborhood level Last year I started a little spice and salad garden on my terrace. It helps localizing my eating patterns but it's a minuscule percentage of my diet :) I am vegetarian today as I've been for 10 years. Sometimes I eat fish though. In doing so I try to make an informed choice. Fishmeal production is the most carbon intensive stage of fishfarming, hence you should go for farmed herbivorous species like tilapia, bream and carp. Wild seafood should be avoided, because of the fuel dependent fishing fleets and the practice of overfishing. In general caring about your food carbon footprint is not easy, it requires research which often provides loads of contradictory numbers and vague rules of thumb like the fact that going veggie and organic doesn't always mean lower emissions: 'food miles' account usually less than actual production (how and where). So buying UK tomatoes if you are in the UK is no better guarantee that the ones from Spain are worse in terms of CO2. For home energy use, well there are more or less simple things that can be done which other commentators pointed out above. Those are all good but the real deal, also in terms of energy self-sufficiency in the face of giant power failures, is decentralized energy infrastructures. We have quite some way - and incentives - to go for this to happen city wide.

What if by applying a fine mist of liquid to a large mass heating element, you could take any liquid to temperatures above said liquid's boiling temperature? What if when you did this you were able to separate molecules in the original liquid? Would the separation of the molecules inside the liquid be a Molecular Change? I first did this to gasoline, applying a fine mist of gasoline to a heating element whose temperature was 600F. I got a white vapor with twice the power that gasoline produces. I also got a non flammable liquid, that would no longer mix with the gasoline it was created from, and I only used temperature to do this. To further prove what I say. I did this same thing to water at between 212F and 230F. I got a flammable gas from distilled water. I used distilled water because the chlorine in public water is inconsistent, and chlorine influences water's boiling temperature. See all 3 of the videos I put on You Tube. Go to Bill Kendrick's You Tube Channel. The videos are, White Gasoline Vapor is a Molecular change, First Flammable gas from Distilled water, and Flammable gas from distilled water. This Flashing Liquid Process can be done to any liquid, to produce a molecular change to any liquid. Finding the right temperature in the liquid will produce a molecular change to that liquid.
