Libri GmbH L'énergie que vous n'utilisez pas : une approche holistique de ce que vous payez réellement

Switching supplier will not fix your bills. Neither will putting panels on the roof - not on their own, and not first. Most of what we are told about saving energy is either wrong or in the wrong order. We are sold a tariff, a boiler, an inverter, a battery - each by someone optimising a single component, none of them looking at the whole. And so we spend, and the bill comes back. This book puts the steps in the right order. Drawing on fifteen years spent across the entire energy supply chain - from the sales floor to procurement and dispatch, and ultimately running a power and gas retailer - Samuele Simonetti explains what you are actually paying for, and what genuinely moves the number. The method is five steps, and the order is not negotiable: measure, reduce, shift, generate - and only then choose your supplier. Inside you will find: - How a bill is really built, and which parts a supplier can and cannot influence - The single reading that reveals what you consume while you sleep - and why it is often a quarter of your bill - Why solar generates when prices collapse, and how to size a system on demand rather than on roof space - How to move consumption without giving anything up, and get free storage without buying a battery - Why your condensing boiler probably never condenses, and the setting that fixes it for nothing - When a heat pump pays, when it does not, and the question to ask before buying one - What shared and community generation actually is - an accounting calculation, not a cable - and how to tell a solid scheme from a fragile one - The pressure tactics used at your door, and four questions that expose them in under a minute Written for people who decide for others. Business owners, building managers, professionals and anyone running a community or an association will find the parts that scale: the same analysis applied to twenty households instead of one. There are no promises of miraculous savings here. In several places the author tells you plainly that something is not worth doing - including things he could have sold you. Includes four appendices: a method for reading any energy bill anywhere in the world, four working checklists to take to your next meeting or site visit, a plain-language glossary, and a guide to finding the rules that apply in your own country. Free reader consultation included. Details at the end of the book.
