Here’s How Blockchain Can Save The Environment

Julie Starr • February 27, 2022



Blockchain is a digital ledger of purchases that is stored in ‘blocks’. The record is decentralized and can be securely stored without the need of a third party to maintain the data. It is the backbone of cryptocurrency like Bitcoin. Cryptocurrencies are making significant steps towards reducing their carbon emissions, making them in many cases far more environmentally sustainable. Here’s how blockchain can save the environment.

Blockchain Companies Committing To Clean Energy

If private blockchain companies commit to going green, this will have a huge impact on both cryptocurrency mining and what the funds generated from mining can be poured back into. Green blockchain companies could encourage green mining farms, and stipulate that funds should be poured into sustainable energy. As the backbone of crypto, blockchain companies can and should hold sway over how digital currency is mined.

Move To A Proof Of Stake System (POS)

Ethereum is one of the first cryptocurrencies to go green, with their new POS concept taking precedence over the old proof of work (POW) system. The POW system is where members of a network, or ‘miners’ have to solve a mathematical puzzle. It is a form of competition used to generate new blocks and currency. It takes a huge amount of energy. POS is an alternative where you stake your coins in order to complete transactions. It takes far less energy to create coins and is a great alternative to the previous model.

The Crypto Climate Pledge

Many blockchain and crypto companies are making an investment in green and clean technology, with the Crypto climate pledge. This Accord stipulates that all crypto and blockchain companies should be creating digital currencies using sustainable energy by 2025. They aim to do this through the use of open source technology and investment into sustainable energy. 

Work With Crypto That Doesn’t Use Mining

There are many new and emerging cryptocurrencies that blockchain companies could work with that do not rely on mining at all. Crypto like Nano has existed since 2015. It uses blockchain-lattice technology, which relies on each user having a unique receive and send block unique to them. They can create their own chain, making this both secure and easy to verify without mining.

Climate Pledges And Redistribution

Blockchain and crypto could help save the environment by using its systems for climate pledges. One proposal would be that countries, states or companies pledge a certain amount of money to reduce their carbon emissions. Should that country, state, or company fail to reduce their emissions, then their deposit would be redistributed to those that have met the terms of their pledge.

Conclusion

Blockchain and crypto have already made huge inroads into reducing their own carbon emissions, with emerging new currencies that move away from mining and instead look at additional encryption or proof of stake workflows to overcome their use of fossil fuels. They are also looking to use their technology to facilitate investment and pledges to reverse climate change.

How Student-Led ‘Energy Audits’ Are Cutting School Costs (and Lighting the Way Forward)

By Julie Starr • July 14, 2025
What happens when students stop waiting for adults to fix things and start conducting their own energy audits? Money gets saved. The lights get switched off. Data gets analyzed. And a quiet revolution in sustainability begins—inside schools that once overlooked their own inefficiencies. Across the globe, student-led energy audits are proving that change doesn't always need to come from a policy shift or a major capital budget. Sometimes, it begins with a clipboard, a spreadsheet, and a group of curious minds asking: Why are the hallway lights on at noon when sunlight floods the building? The Energy Detectives These audits aren’t science fair projects. They’re rigorous investigations, often done in collaboration with facilities staff, local environmental nonprofits, or even engineering mentors. Students go from classroom to classroom measuring electricity usage, checking for phantom loads , and identifying where heat is escaping in winter or air conditioning is leaking in summer. One high school in Ontario saved over $12,000 a year after its Grade 11 physics students ran an energy audit and suggested simple changes—LED upgrades, motion sensors in bathrooms, and smarter heating schedules. They didn’t just propose ideas. They pitched them with spreadsheets, thermal images, and payback timelines. It worked. Learning That Pays Off—Literally Unlike textbook learning, these audits blend real-world math, environmental science, economics, and persuasive communication. Students aren’t just learning about sustainability. They’re doing it. And the savings add up. From dimming overlit hallways to reprogramming HVAC systems that run all weekend for empty buildings, students are surfacing blind spots that administrators often overlook. In some districts, their findings are influencing energy policy. Elsewhere, the audits have inspired school boards to hire sustainability coordinators—often alumni of the student programs themselves. There’s something poetic about a school funding new books or laptops from money saved by students who found out the vending machines didn’t need to be plugged in 24/7. Why This Matters More Than Ever With education budgets tightening and utility costs rising, every dollar saved is a dollar that can go back into classrooms. And here’s where it gets interesting from a family finance perspective, too. If you’re a parent setting aside money for post-secondary savings, every bit of school efficiency helps. Fewer energy costs might mean more programming, better STEM facilities, or even bursaries. That raises a broader point: when families save for their children’s future, they often look into RESPs (Registered Education Savings Plans). And many wonder—is a RESP deduction available on my taxes? While contributions themselves aren’t deductible, the gains grow tax-free, and students often pay little to no tax when they withdraw the funds during school. A Movement Worth Replicating These audits aren’t just an exercise in environmentalism. They’re leadership labs. Students learn how to spot inefficiencies, speak up in board meetings, and make a business case for change. They don’t just flip switches—they shift mindsets. And they carry these habits into adulthood. The result? A generation growing up not only with climate anxiety, but also with tools to tackle it.

Smart Sensors, Smarter Supply Chains: Enhancing Traceability in Food & Beverage

By Julie Starr • June 20, 2025
In today’s competitive food and beverage (F&B) landscape, traceability is no longer a compliance checkbox—it’s a differentiator. The ability to track every step of a product’s journey, from origin to shelf, is vital for regulatory accuracy and to ensure brand integrity, supply chain agility, and consumer trust. Add smart sensors to the mix: the quiet, tireless observers revolutionizing supply chain intelligence. Traceability Has a Data Problem Despite digitization across many F&B operations, most traceability systems still rely on fragmented or manual data inputs. Batch numbers, barcodes, and handwritten logs often stand between a supplier and clarity when things go wrong. This approach struggles with latency and scale. When contamination or delays occur, root cause analysis is slow, costly, and damaging. Smart sensors shift this paradigm by embedding real-time, contextual intelligence into every stage of the supply chain . Whether monitoring humidity in transit or recording fill-level precision in bottling plants, they remove the guesswork by turning physical conditions into structured, time-stamped data. From Passive Monitoring to Active Optimization Sensors used to be reactive tools, alerting operators to anomalies. But smart sensors now play a proactive role in process control. They measure, and they interpret. For example, temperature sensors embedded in cold chain logistics can dynamically adjust cooling systems or flag threshold breaches before spoilage occurs. These advancements reduce waste and loss at a systemic level. In a production facility, smart sensors integrated with PLCs can enforce recipe compliance, verify clean-in-place processes, and detect micro-stoppages in real-time. This enables operations to pivot faster and isolate inefficiencies before they cascade downstream. Trust is Built on Transparency Consumers are paying more attention to what they eat and drink. They’re looking beyond labels, expecting visibility into how ingredients are sourced, processed, and handled. Smart sensors make this level of transparency achievable —without burdening manufacturers with excessive manual oversight. By capturing metadata throughout production and distribution, these sensors create a digital footprint that’s tamper-resistant and instantly accessible. When this data is integrated with a central platform, brands can respond confidently to audits, recalls, and quality assurance challenges with a level of precision that would be impossible through legacy systems. Intelligence Without Infrastructure Overhaul One common misconception is that adding smart sensors requires a top-down reinvention of supply chain infrastructure. In reality, companies can deploy edge sensors in a modular, scalable way. Many modern solutions offer plug-and-play functionality, allowing for fast integration with existing machinery and MES systems. This is where suppliers like alps-machine.com are reshaping expectations. Rather than pushing proprietary ecosystems, they design sensor-ready equipment with interoperability in mind. This future-proofs investment and keeps businesses nimble in the face of regulatory or market shifts. Designing for Data Longevity Sensors are only as powerful as the context they capture. A smart implementation ensures the data collected can be standardized, stored securely, and accessed meaningfully across departments. This means moving beyond local dashboards toward centralized, queryable datasets that inform everything from supplier contracts to marketing claims. As AI and predictive analytics become more accessible, these data-rich environments will unlock new capabilities—such as predicting demand spikes based on real-time freshness indicators or adjusting production schedules dynamically based on in-transit sensor feedback. Final Thoughts: Smarter Isn’t Optional Traceability isn’t solved by more paperwork—it’s solved by embedded intelligence. Smart sensors don’t just help businesses know what happened; they help prevent the wrong things from happening at all. For companies in the food and beverage sector, adopting smart sensors is less about chasing innovation and more about enabling resilience, speed, and confidence in every decision.
