fix: img urls

- Implemented /_img/ rewrite in next.config.mjs to proxy requests to IMGPROXY_URL
- Updated lib/imgproxy.ts to use local /_img path instead of public endpoint
- Replaced NEXT_PUBLIC_IMGPROXY_URL (build-time) with IMGPROXY_URL (runtime) env var
- Updated docker-compose.yml to strip build args and inject runtime IMGPROXY_URL
- Cleaned up Dockerfile and audit scripts

 # 100 % erneuerbare Energie? Nur mit der richtigen Kabelinfrastruktur!
 Die Vision ist klar: Ein Europa, das seinen Strom zu 100 % aus erneuerbaren Energien gewinnt. Doch während Solar- und Windparks boomen, hinkt der Ausbau der Stromnetze hinterher. Die Ursache? Eine Infrastruktur, die für fossile Kraftwerke gebaut wurde und mit den neuen Anforderungen nicht Schritt hält.

 ### Warum Kabelhersteller jetzt durchstarten sollten
 Es wird viel über Subventionen, Fördergelder und deren Verwendung gesprochen. Doch die eigentliche Herausforderung bleibt: Die notwendige Infrastruktur muss geschaffen werden – und das gelingt nur mit leistungsfähigen Kabeln.
 Die folgenden Trends sind für uns besonders relevant:
-- <strong>Ausbau von Stromleitungen und Netzanschlussprojekten:<br />
-
-</strong>Mit dem beschlossenen Milliardenpaket ist klar: Stromleitungen, die erneuerbare Energiequellen wie Onshore-Windparks oder Solaranlagen anbinden, müssen massiv ausgebaut werden. Dabei geht es in erster Linie um die Integration der Stromerzeugung aus Windkraftanlagen ins Netz.Unsere Nieder-, Mittel- und Hochspannungskabel sind dafür ausgelegt, diesen Anforderungen gerecht zu werden.
-- <strong>Dezentralisierung der Energieversorgung:<br />
-
-</strong>Ein weiteres zentrales Thema ist der Trend zur [dezentralen Energieversorgung](https://energas-gmbh.de/dezentrale-energieerzeugung/). Immer mehr Energie wird direkt vor Ort erzeugt – und muss zuverlässig ins Netz eingespeist werden. Auch hier sind leistungsfähige Erdkabelsysteme gefragt, die sich durch hohe Belastbarkeit und Widerstandsfähigkeit auszeichnen.
-- <strong>Klimaschutzmaßnahmen und klimafreundlicher Umbau der Wirtschaft:<br />
-
-</strong>Da 100 Milliarden Euro speziell für den klimafreundlichen Umbau vorgesehen sind, können wir davon ausgehen, dass Projekte zur Elektrifizierung, CO2-Reduktion und zum Ausbau regenerativer Energien massiv gefördert werden.

 ### **Die Rolle von KLZ in dieser gigantischen Investitionsoffensive**
 Mit diesen milliardenschweren Investitionen wird der Bedarf an Erdkabeln, insbesondere Mittelspannungskabeln, geradezu explodieren. Die Frage ist nicht, **ob** Kabel gebraucht werden – sondern **wann und in welchen Mengen**. Und genau da kommen wir ins Spiel.

 But why does this happen? Every cable has a resistance that slows down the flow of electricity. The poorer the quality of the cable, the more energy is lost in the form of heat. This means that less of the electricity produced by the solar system actually reaches you and can be used. And that is obviously a problem, especially when you consider how much is invested in the installation of a solar system.
 ### Green energy is a central component of our future today … But it is not enough to simply rely on these energy sources. The infrastructure that brings this energy to us efficiently plays an equally crucial role.
 High-quality cables, on the other hand, have better conductivity and lower resistance. This ensures that the **electricity flows more efficiently and less is lost**. This leaves more of the generated energy for you to use – which is not only good for your electricity bill, but also helps to maximize the sustainability of your solar system. So it’s worth paying attention to quality when choosing cables in order to exploit the full potential of green energy.

 <h4>Fact 2: Wind farms without energy storage are not that efficient</h4>
 Wind farms have a similar problem to solar plants: energy losses due to fluctuating power generation. Imagine a wind farm produces electricity, but the wind does not blow constantly. This means that at certain times the wind turbines generate more electricity than is actually needed, while at other times, when the wind drops, they can supply almost no electricity at all. In both cases, a lot of energy is lost or not used. Without a way to **store surplus energy**, there is a gap between the energy generated and the actual use, which significantly reduces the efficiency of the entire system.The solution to this problem lies in** energy storage systems** such as batteries or pumped storage power plants. These technologies make it possible to store surplus energy when the wind is blowing strongly and therefore more electricity is produced than is required at the moment. This stored energy can then be used on demand when the wind dies down or demand is particularly high. This ensures that all the electricity generated is used efficiently instead of being lost unused. Without these storage technologies, the full potential of wind energy remains untapped and the efficiency of wind farms remains far below their actual value.
 However, despite their importance, energy storage systems are associated with challenges. High costs and limited capacity continue to make the development and installation of these storage technologies a difficult endeavor. But technological progress has not stood still: New innovations in storage technologies and increasingly improved scalability are making it more and more realistic to equip wind farms with **effective and cost-efficient storage systems**. This is crucial for the future of wind energy, because only by overcoming these challenges can wind energy fully contribute to ensuring a stable and sustainable energy supply.

 <h4>Fact 3: Power lines can be used as habitats for biodiversity</h4>
 Did you know that power lines – the high-voltage lines that transport electricity from power plants to our homes and businesses – can also be used as** habitats for animals and plants**? These areas, which often need to be kept clear to make room for the power lines, provide a valuable opportunity to actively promote biodiversity and contribute to environmental stewardship at the same time.Traditionally, the areas along power lines have often been regarded as “wasteland” with no particular significance. However, innovative approaches to green infrastructure are increasingly creating valuable habitats here. Today, wildflower meadows, bee pastures and shrubs are planted along power lines, providing habitats for many endangered species. These meadows are not only a source of food for bees, butterflies and other pollinators, but also a refuge for birds and small animals that are finding less and less habitat in other parts of the landscape.
 In Germany, this is a growing concept known as “**ecological route maintenance**”. Here, care is taken to ensure that the areas along the power lines are designed in a near-natural way so that biodiversity is promoted. This creates flowering meadows and habitats for numerous insect species, which are finding less and less space due to the intensive use of agriculture and urbanization. There are also similar projects in Switzerland in which nature is specifically promoted along power lines.

 <h4>Technology: Advanced designs for optimal performance</h4>
 Advanced cable technologies are critical to maximize the performance and safety of electrical systems, especially with regard to renewable energy sources. Two key technologies are insulation and sheathing, and specialized cables for renewable energy.
 **Insulation and sheathing: quality meets safety**<br />
 The insulation of a cable protects against short circuits and external influences such as moisture or mechanical damage. Materials such as PVC, PE and XLPE offer excellent protection and guarantee safe power transmission. The protective sheath protects the cable from UV radiation and extreme temperatures, which significantly extends its service life and increases safety.**Cables for renewable energy sources**<br />
 Solar and wind energy require specialized cables that can withstand extreme weather conditions and high loads. Solar cables must be UV resistant and suitable for DC systems, while wind power cables must be flexible and corrosion resistant to withstand the constant movement of rotor blades. These advanced cables enable the efficient and safe transportation of energy, which is crucial for the sustainability and economic viability of renewable energy.
 Overall, these technologies help maximize the efficiency and safety of cables and support a sustainable energy future.

 <h4>Conclusion: What really makes a first-class cable</h4>
 A first-class cable is characterized by a perfect balance between quality, efficiency and sustainability. Choosing the right cable is not just a question of technical requirements, but also an important step towards a more sustainable future. A high-quality cable ensures reliable performance and maximum efficiency, reduces energy loss and at the same time offers a high standard of safety.**Quality and efficiency**<br />
 A good cable is designed to work efficiently over the long term. Materials such as copper and aluminum ensure excellent conductivity, while modern insulation materials and protective layers extend the cable&#8217;s service life and protect it against external influences such as moisture and corrosion. This is particularly important in applications such as power transmission and the use of renewable energy, where efficiency and reliability are top priorities.
 **Sustainability**<br />
 In a world that is increasingly focusing on sustainability, environmental protection is playing an ever greater role when choosing a cable. Recyclability, sustainable production processes and certifications such as RoHS or recycling seals are decisive factors that determine the ecological footprint of a cable. Integrating these elements into cable production helps to minimize resource consumption and reduce waste, which contributes to a more environmentally friendly and resource-efficient future.
