Explanation: Thermoelectric generators convert temperature differences into electricity, increasing overall energy efficiency.

Explanation: Green tech is designed to reduce environmental impact through energy efficiency, pollution reduction, or sustainable materials.

Explanation: Green chemistry emphasizes safer, more sustainable chemicals and processes across industries.

Explanation: Green walls use plants to filter indoor air, absorb CO₂, and improve aesthetics naturally.

Explanation: Remanufacturing restores used products to like-new condition, saving resources and energy.

Explanation: Biodegradable electronics break down naturally, lowering long-term electronic waste.

Explanation: Compostable packaging materials decompose naturally and reduce landfill waste.

Explanation: Products designed for disassembly are easier to repair, reuse, or recycle, supporting circularity.

Explanation: CCS technology traps CO₂ from industrial processes and stores it underground to prevent it from entering the atmosphere.

Explanation: Smart grids enhance energy efficiency by adjusting electricity flow based on real-time usage and demand.

Explanation: A+++ rated appliances are energy efficient, saving electricity and reducing emissions.

Explanation: Precision agriculture reduces input waste by applying water, fertilizer, or pesticides only where needed.

Explanation: Silicon is the most common material due to its abundance and excellent photovoltaic properties.

Explanation: BIPV replaces conventional building materials with solar panels, merging function and power generation.

Explanation: 3D printing minimizes material waste by building layer by layer only where needed.

Explanation: Lithium-ion batteries store energy efficiently and are key to renewable energy systems.

Explanation: UV disinfection kills pathogens without chemicals, making it a clean water treatment method.

Explanation: Hempcrete absorbs CO₂ as it cures, helping lower the building’s overall carbon footprint.

Explanation: Circular technologies aim to keep products in use longer and reintroduce materials back into production.

Explanation: Bamboo is a rapidly renewable, low-impact material used in sustainable construction.
