<h2>What is Energy Harvesting? 💡</h2>
<p>At its core, energy harvesting is the process of capturing tiny amounts of energy from the environment and converting them into usable electrical power. Think of it as scavenging for energy that's everywhere around us, but often goes unnoticed or unused. While traditional renewable energy sources like large solar panels or wind turbines focus on macro-scale power generation, energy harvesting targets micro-scale power needs, often for low-power electronic devices.</p>
<h3>Why is it So Important Now? 📈</h3>
<p>The rise of the Internet of Things (IoT), wearable devices, and countless sensors scattered across our world has created an immense demand for self-sustaining power sources. Batteries, while essential, have limitations: they need recharging or replacement, contributing to e-waste and increasing maintenance costs. Energy harvesting offers a compelling alternative, enabling devices to operate autonomously, often for their entire lifespan, with minimal environmental impact. This isn't just about 'going green'; it's about making devices smarter, more reliable, and ultimately, more profitable.</p>
