CO2-reducing conveying systems

Das hier ist als Vorschlag zu verstehen, aus welchen Abschnitten ein Maßnahmentext bestehen kann. Es ist unwahrscheinlich, dass es für eine einzelne Maßnahme sinnvoll ist, sämtliche Überschriften abzuarbeiten. Alles was für die jeweilige Maßnahme nicht benötigt wird, sollte dann der Übersicht wegen einfach gelöscht werden. Dazu, wie das Muster in einen Maßnahmentext übernommen wird, siehe Eine Maßnahme neu erstellen (Punkt 5).


What's the problem?

It is scientifically proven that we only have barely nine years left to shift the levers (see also points 6 to 9 in: https://www.scientists4future.org/fakten/ and a summary of climate-impacting climate protection facts), which means that we must be ready to convert the fossil economy to renewable energies by 2035.

"Energetic renovation", which only save fossil fuels, are the most uneconomic measures available. Under laboratory conditions, these achieve an average of 25% savings (fossil fuels) for a single measure, such as switching to condensing technology or external wall insulation (https://www.bee-ev.de/fileadmin/Publikationen/Studien/20180323_BEE_Gutachten_Einsparungen_von_Endenergie_und_CO2_beim_Ersetzen_alter_Heizkessel_durch_Brennwertkessel.pdf ).

Even if 40 % or more is achieved, this means that at least 60 % more fossil fuels must be burnt, usually for more than 10 years.

Another negative aspect is the fact that even today, after an old, classic energy saving measure, the investors/house owners pay more for energy after only a few years than before the "renovation".

The refurbishment rate in existing buildings must be well over 6% per year. Because we have no more time.

The previous bases for subsidies, such as the current energy target value kWh/m2 per year for energy-related subsidies for existing buildings, have not achieved an increase in the rate of refurbishment of existing buildings for years. It is even negative. The target value as a criterion for the payment of subsidies prevents the → energy transition in the building sector. Important CO2 potentials are wasted unnecessarily.

For this reason, the funding criteria for energy-related refurbishments must be completely restructured and converted to real CO2 savings or an increase in the refurbishment rate > 6 %.


What's the measure?

Consequence: the old conductivity value kWh/m2 per year must be replaced.

Ideally, this would involve a shift to subsidies, which are tied to a mandatory CO2] savings quota per building.


A positive aspect here is:
With a correspondingly low minimum volume (for example > 60% CO2 savings rate per building) oil and natural gas heating systems are no longer profitable.
E-vehicles can be charged with renewable combined systems (photovoltaic/electric storage and renewable heating/heat storage with controls). Here, too, a shift to CO2 promotion brings a lot of benefits.
Subsidies for e-vehicles can only be paid out if, for example, the charging current was generated CO2-free. This is the case with green electricity providers (100%). At the same time, this will also force dirty electricity producers with coal and nuclear power out of the market.


How can the implementation look like?

If a renewable energy system with photovoltaic/electricity storage and renewable heating with heat buffer (layer) storage as well as an effective control system is installed, no more oil or natural gas has to be burned.

Consequence: No more oil or gas has to be burned and the CO2 savings rate for heating is 100%. The photovoltaic system usually generates more than 50 % less household electricity, which means drastic reductions in CO2, coal and nuclear waste in the electricity mix. Only the additional winter electricity is added to this in the balance.

In the same building, up to 100% fossil fuels and > 50% in electricity (SIMULTANEOUSLY in the same building) have long been installed in buildings and are operating through renewable and financially viable energy systems.


How will this counteract climate change??

The housing stock includes approx. 13 million 1-2 family houses and 2.7 million apartment buildings. (Source: www.unendliche-energie.de ).  Many of these houses are older than 25 years, including their heating systems. It is estimated that about 70% of these houses are in urgent need of renovation of the heating systems.  For many non-residential buildings with heating systems, such as office buildings, restaurants, businesses, churches, town halls and so on, there obviously is a great need for renovation as well.


What other effects does the measure have?

Up to 100% no more import oil/natural gas per building means a noticeable relief for the environment and heating costs.  Since heating accounts for approx. 70% of the total building energy (approx. 50% with motor vehicles), not only the reduction rates but also the energy costs increase. There are also positive effects in the case of loan repayments and/or financing, as the payback periods are considerably shorter despite the minimally higher investment sum. This is an essential factor for profitability calculations.

If the German government relies only on tax incentives, does not promote comprehensive → energy system transformation consultations or continues to apply the previous saving measures under the old guidelines, the Paris climate protection goals will never be achieved.


How quickly can the measure be implemented?

Municipalities, cities, districts, Federal States, but also private/public institutions can set up their own CO2 promotion programmes and, if necessary, finance them privately. This is done by means of crowdfunding, crowdfinancing, contracting, leasing or favourable loans from private/non-commercial/governmental sources of finance. As a result, many projects with previously impossible financing can now be implemented quickly. However, one problem for a targeted implementation is the execution by qualified craftspeople.


How long does it take for the measure to take an effekt?

Without simultaneous training for a sufficient number of craftspeople, there is even a risk that the climate targets will not be achieved in time.


References to other measures

This could include comments on possible conflicts with other measures, but also other references, e.g. when measures are interdependent in order to be effective (e.g. because otherwise displacement effects would occur).


Problems of social, global and generational justice

Prosumers have multiple positive effects on social justice. Because by drastically reducing the previous 100% dependence of the energy suppliers (electricity, oil/gas/petrol/diesel), the old centralised companies are losing turnover and thus power. The investors can exchange/bill energy among themselves via storage/energy lines and thus initiate the energy transition from below themselves.

Local energy suppliers generate new business segments through a decentralized energy transition based on prosumers and earn more in total than before, when only energy generation, delivery and invoicing were the operative business.

Background:
The current subsidy systems are based on classic energy-related refurbishment measures. They aim at avoiding heat losses.
This delays the time until leaving the living space/house. The boiler starts less accordingly.
However, this means that the climate protection measure only reduces fossil fuels. Thus, all current support measures are based on CO2-generating fuels.
The previous funding bases, such as the current energy target value kWh/m2 per year for energy-related subsidies for existing buildings, have not achieved an increase in the renovation rate for existing buildings for years.
The "success rate" of the guide value is rather drastic. This is because the energy-related refurbishment of existing buildings is currently below 1%. But we need at least 6 % per year.
In addition, saving rates average less than 30 %, even though renewable technologies, especially combined technologies with photovoltaics/solar heat, have long been ready for use and economically viable.
This means that at least 70 % of CO2 savings quotas are wasted per building.

Consequence: the old conductance value must be replaced.

Ideally with a shift to subsidies that are tied to a CO2 savings quota per building.
A positive aspect here is:
With correspondingly low minimum volumes (for example >60% CO2 savings rate per building) oil and natural gas heating systems no longer pay off.
With combination systems, electric vehicles can also be charged. Here, too, a shift to CO2 production would be very useful.
Subsidies for e-vehicles can only be paid out if, for example, the charging current was generated CO2-free. This is the case with green electricity providers (100%). At the same time, this will also force dirty electricity producers with coal and nuclear power out of the market.
