• Energy-Efficient Appliances: Modern appliances with high energy ratings (like Energy Star in the US) are designed to consume significantly less power than older models.
• LED Lighting: Light-emitting diodes use a fraction of the electricity of traditional incandescent bulbs and last much longer.
• Smart Grids: Advanced electricity networks that use digital technology to monitor, control, and optimize the delivery of electricity from suppliers to consumers. This reduces waste and integrates renewable sources more effectively.
• IoT (Internet of Things) for Sustainability: Sensors and connected devices can monitor everything from air quality and water leaks to traffic flow, providing data that helps optimize resource use in cities and industries. For example, smart irrigation systems can water crops only when necessary, saving vast amounts of water.

3. Waste Reduction & The Circular Economy

Traditionally, we’ve had a "take-make-dispose" economy. Sustainable technology is pushing us towards a circular economy, where waste is designed out, and resources are kept in use for as long as possible.

• Advanced Recycling Technologies: Innovations in sorting and processing make it possible to recycle more types of materials, including complex plastics and electronics (e-waste).
• Upcycling: Transforming waste materials into new products of higher quality or value.
• Composting Solutions: Technologies that accelerate the breakdown of organic waste into nutrient-rich soil.
• Biodegradable Materials: Developing alternatives to plastics and other non-degradable materials that can naturally break down after use.
• Product-as-a-Service Models: Companies retaining ownership of products (like carpets or electronics) and leasing them, ensuring they are repaired, reused, or recycled at the end of their service life.

4. Green Computing & Sustainable IT

Even our digital lives have an environmental footprint. Green computing aims to minimize the environmental impact of IT operations.

• Energy-Efficient Hardware: Designing computers, servers, and data centers that use less power.
