 <WRAP tip> Quicklinks to measures: **[[:efficiency_now:building_envelope|Building Envelope]]** and ** [[:efficiency_now:building_service|Building Service]]**. Having problems finding a skilled worker? Or are products "sold out"? That's no reason to do nothing; you can simply begin work on something else. In many cases, our tips for structural as well as technical measures can be followed on a do-it-yourself basis. Some 'problems' do not exist at all: it is not necessary to begin with a specific measure - the effects of the results will usually be cumulative. What matters is that if something is worth doing at all, then it's worth doing it well! Further measures that will be implemented later on must also be kept in mind: e.g. the subsequent renewal of windows. Everything should be done in such a way that later measures are facilitated and good connection details are possible. Here is more information about **[[:efficiency_now:gas_consumption|]]**.\\

 ===== Unused potentials =====
-In the article linked here, we have analyzed retrospectively how big the effect of the measures suggested here can be in practice: Analysis: [[https://passipedia.de/energieeffizienz_jetzt/brach_liegende_potentiale|Unused potentials (German only)]]. Indeed, there was a time when we used to pursue these possibilities more seriously than we do today((not really serious enough even at that time, but still…)) . These improvements have been stagnating since around 2010; there were many reasons for this, the most important was the fact that on account of the "revival" of new construction activity, the construction industry no longer made efforts to improve the existing building stock. The illusion of [[:efficiency_now:natural_gas_and_climate_protection|cheap and sustainable natural gas]] also played a big role in this - a great many people believed this. Added to this was the delusion that we "already run almost everything using renewable energy"((Stickers with "climate neutral" were used even if this was largely faked, through compensation payments e.g. for preservation of rainforests, which Bolsonaro still allows to be chopped down in the end; a modern form of absolution payments.)) . Actually, only those measures which genuinely lead to a reduction in the consumption of fossil energy will help. Those are investing in renewable energy and the reduction of the still extremely high energy losses in the current system; the vast majority of these losses occur at the end of the supply chain - when an incandescent bulb heats away 60 watts instead of the just 3.5 watts that are needed today, or the equivalent of 350 liters of heating oil vanishes through the top floor ceiling that is still inadequately insulated. We can change that - and that's what these pages are for: to explain how we can approach this with a good chance of success and not at over-inflated prices either: **[[:efficiency_now:building_envelope|structural measures]]**and measures relating to **[[:efficiency_now:building_service|building services systems]]**.
