PEHDs ile Temiz Enerji Üretimi ve Çevresel Sürdürülebilirlik için Önemi

Öz

Elektrik, günümüz toplumunda temel enerji sağlayıcıdır ve sürdürülebilir gelecekte hayati rol oynamaktadır. Güneş veya rüzgâr enerjisi gibi temiz ve yenilenebilir kaynaklardan üretilen elektrik, daha az sera gazı emisyonu (GHG) kaynağıdır. Gelecekte artan talebi karşılama ve emisyonları azaltmada çevredeki farklı kaynaklardan elektrik üreten enerji hasadı teknolojileri ile güneş ve rüzgâr enerjisi gibi doğal kaynakları kullanan yenilenebilir enerji sistemlerinin entegre edildiği bütüncül enerji politikaları önemli rol oynayacaktır. Piezoelektrik enerji hasadının, özellikle güneş, rüzgâr vb doğal yenilenebilir enerji kaynaklarından yararlanılamayan metro, alışveriş merkezleri (AVM) vb. iç ortamlarda kullanımı modern yapı vizyonunda dönüm noktası olarak kabul edilmektedir. Piezoelektrik enerji hasadı sistemlerinin kurulduğu basamak ise özellikle yüksek doluluk ve yoğunluğa sahip alanlarda iç ortam enerji üretimi için en umut vericisidir. Bu çalışma da piezoelektrik teknolojisinin temel kavramları sunuldu, enerji tüketimi ve emisyon salınımına önemli katkı sağlayan başta metro vb iç ortamlardaki yürüyen merdivenlerde olmak üzere birçok sektöre entegre edilebilir hareketli PEHDs basamak tasarlandı, güç üretim kapasitesi, yatırım maliyeti, ekonomik verimliliği incelendi. Sonuçlar klasik sistem ile piezo sistemin mekanik kurulum maliyetlerinin benzer olduğunu gösterdi. Hesaplamalar, 20 basamaklı yürüyen merdivenin %75 dolulukta enerji gereksiniminin ilave enerjiye gereksinim olmadan PEHDs basamak ile karşılanabildiğini gösterdi. Ayrıca klasik sisteme göre (yılda 18250 kWh enerji tüketimi), piezo sistemin (disklerin kullanım ömrü süresince, sıfır işletme maliyeti) hem temiz/sürdürülebilir hem de ekonomik enerjji kaynağı olarak kullanılabileceğini gösterdi.

Clean Energy Generation with PEHDs and Its Importance for Environmental Sustainability

Öz

In today's world, electricity is a fundamental energy resource and is important to a sustainable future. Electricity produced from clean and renewable sources such as solar or wind energy is a source of lower greenhouse gas emissions. Holistic energy policies that integrated renewable energy systems using natural resources such as solar and wind energy with energy collection technologies that generate electricity from various environmental sources, will play an important role in meeting the increasing demand in the future and reducing emissions. Piezoelectric energy harvesting is regarded as an innovation in the modern constructions, particularly in indoor environments like subway lines, malls, etc., where natural renewable energy sources cannot be utilized.The step where piezoelectric energy harvesting systems (PEHDs) are installed is one of the most promising for indoor power generation, especially in areas with high occupancy and crowds. In this study, the fundamental concepts of piezoelectric technology were presented. A movable PEHDs step was designed that can be integrated into many sectors, primarily in escalators in indoor environments, which significantly contribute to energy consumption and emission release, and their power production capacity, cost of construction, and economic efficiency were examined. The results showed that the mechanical construction costs of the piezo system are similar to those of the classic system. According to calculations, the energy requirement of a 20-step escalator at 75% occupancy could be met by the PEHDs step without the need for additional energy. In addition, compared to the classic system (with an annual energy consumption of 18250 kWh), the piezo system ($0 operating costs during the disks' lifetime) is both a clean/sustainable and economic energy source.
