Clearly, tech must evolve to operate more sustainably if its benefits are to continue far into the future without severely damaging the planet. The good news is that many innovators are tackling these issues head-on with renewable, recyclable, and eco-conscious products. Let's explore some of those solutions next.
Sustainable Solutions in Data Centers
Data centres powering cloud infrastructure and networks consume staggering amounts of electricity for servers, cooling, and facilities. However, tech leaders are making data storage and processing more environmentally-attuned. Here are a few examples:
Google Data Center Innovations
Google aims to match 100% of its yearly energy use with renewable sources by 2030. Its cloud platform already leverages huge AI/ML models to auto-optimise data centre temperatures, airflow, electrical distribution and more for maximum efficiency. This "digital twin" approach saves over 30% energy versus traditional facilities.
Google also reuses “waste heat” from servers to heat buildings nearby through its micro-combined heat and power plants. The company repurposes 95% of its water for cooling multiple times as well before treating and releasing it. Its state-of-the-art data centres even produce more energy than consumed annually.
Microsoft’s Underwater Data Center
Taking server cooling underwater, Microsoft partnered with startup Nordic Aquafarms to place a data centre on the ocean floor near Orkney, Scotland. The frigid sea water helps regulate temperatures passively through a heat exchanger system. The underwater facility reduces energy use for cooling by over 90% versus land-based data centres.
The site also leverages wave power for renewable electricity. While still experimental, this novel approach could help data centres operate in a zero-carbon manner. Additional ocean-based models aim to utilise tidal and offshore wind power too for zero-emission cloud infrastructure globally.
Apple’s Renewable Push
Today, Apple matches 100% of its global corporate electricity usage with renewable energy through initiatives like power purchase agreements for solar and wind farms in 24 countries. It also achieves net zero carbon emissions across direct supply chain and product use with its Swift foundation.
Apple's data centres like those in North Carolina leverage technologies like floating solar panels, battery storage and fuel cells fueled by food waste to operate on renewable energy even when the sun isn't shining or wind blowing. Its purpose-built renewable energy storage helps ensure a zero-carbon data experience for customers at all times.
Innovations in Green Electronics
Consumer devices have big environmental impacts from material extraction to power needs during use-phase and disposal. Here are some notable tech firm projects reducing electronics’ footprint:
Fairphone's Modular Design
Dutch social enterprise Fairphone builds smartphones entirely focused on fair working conditions, conflict-free minerals, and long-term use through modularity. Users can swap out broken components like batteries, cameras and screens themselves. Fairphones contain recycled plastics, rare earths, and gold from conflict-free sources.
Their repairable design meansdevices last 4-5 years on average versus typical 2 years. It dramatically reduces e-waste. Fairphone also actively lobbies brands to make devices more durable and upgradable overall. Their work sets an example for a more sustainable electronics industry.
HP’s Sustainable Materials
HP employs several techniques to make PCs and printers from post-consumer recycled plastics, and aims for 100% of ink/toner cartridges to be recyclable. Their DreamColor displays also utilise Bio-PBST made from sustainably-harvested castor plants for rigid portions rather than oil-based plastics.
HP incorporates ozone-safe propellants in aerosol cleaners too and uses minimal or no paints/coatings on hardware to ease future disassembly and recycling. Their Planet Partners program handles the responsible end-of-life disposal of products.
Dell Circular Innovation
Dell's Circular Innovation approach means designing products with reuse, repurposing, and recycling from the initial blueprint stage. New Alienware and Latitude PCs contain ocean-bound plastics and use 35-60% recycled content via closed loop manufacturing techniques.
Dell further facilitates device trade-ins for credit towards new purchases, while recovering up to 91% of retired product materials through resale and disassembly. Their refurbished systems provide cost-effective, green alternatives for consumers as well.
Samsung E-Waste Solutions
Samsung's Galaxy Upcycling program reengineers retired smartphones and tablets into affordable Internet of Things (IoT) devices with new utility like home monitoring. This “upcycling” prevents waste through innovative repurposing practices. The firm additionally deploys AI-enabled robots capable of separating out over twenty different types of battery components for recycling.
Samsung plays an advisory role with the UN on sustainable mineral sourcing as well. Its Galaxy for the Planet 2025 initiative targets plastic neutrality and sustainability certification for all products through material innovation and closed-loop manufacturing globally.
Greening Cryptocurrency & Blockchain
While blockchain's decentralised capabilities fascinate many, studies show the energy intensity of cryptocurrency networks like Bitcoin currently outweigh benefits. However, new crypto projects are going greener:
Cardano & Proof-of-Stake
Cardano runs on a proof-of-stake consensus model which is over 99% more energy efficient than Bitcoin's proof-of-work currently used. Stakers securely validate transactions by "bonding" their coins rather than expanding vast sums on energy-hungry mining rigs.
Cardano's Ouroboros protocol adjusts network difficulty based on available nodes so power demand scales only with real-world use, not mining reward arms races. This "green alternative" to Bitcoin offers faster, cheaper transactions while preserving decentralisation far better for the climate.
Helium & IoT Crowdsourcing
Network operator Helium instead crowdsources blockchain coverage through community-installed hotspots worldwide utilising low-power LongFi capabilities. Individuals earn crypto Rewards by sharing excess bandwidth on their home/business WiFi router for IoT device connectivity.
This novel approach to IoT infrastructure taps unused spectrum in cities to form self-organising "People's Networks". Being powered by members' existing internet means Helium requires only hundredths of watt mining versus megawatts of cryptocurrencies.
Algorand & Carbon-Negative Blockchain
Algorand proposes making blockchains actually carbon-negative through carbon credit offerings. Its native protocol requires negligible electricity for mining/validating transactions via a unique pure proof-of-stake algorithm proven as efficient as centralised systems.
