Green Computing Technology

Green Computing

What Is Green Computing?

Green computing, also called sustainable computing, aims to maximize energy efficiency and minimize environmental impact in the ways computer chips, systems and software are designed and used.

Also called green information technology, green IT or sustainable IT, green computing spans concerns across the supply chain, from the raw materials used to make computers to how systems get recycled.

In their working lives, green computers must deliver the most work for the least energy, typically measured by performance per watt. Green computing involves reducing the use of hazardous materials, maximizing energy efficiency during the product’s lifetime, and promoting the recyclability or biodegradability of defunct products and factory waste.

One key area where green computing is making a significant impact is in data centers. These centers, which house servers and other computing equipment, consume vast amounts of energy and can have a considerable environmental footprint. Here are some strategies for building eco-friendly data centers:

  • Energy-Efficient Hardware: Use energy-efficient servers, storage devices, and networking equipment. Look for Energy Star and EPEAT certifications.
  • Virtualization: Use virtualization technology to reduce the number of physical servers needed. Virtual servers can run multiple applications, increasing utilization rates and reducing energy consumption.
  • Energy-Efficient Cooling: Implement efficient cooling systems, such as hot aisle/cold aisle containment, economizers, and liquid cooling, to reduce the energy required for cooling.
  • Renewable Energy: Power data centers with renewable energy sources, such as solar, wind, or hydroelectric power, to reduce reliance on fossil fuels.
  • Server Consolidation: Consolidate servers through virtualization or cloud computing to reduce the overall number of physical servers, thereby reducing energy consumption.
  • Energy Management Software: Use software to monitor and manage energy usage in real-time, identifying areas for optimization and efficiency improvements.
  • Recycling and Disposal: Ensure proper recycling and disposal of old equipment to minimize the environmental impact of e-waste.

Why Is Green Computing Important?

Green computing is a significant tool to combat climate change, the existential threat of our time. Global temperatures have risen about 1.2°C over the last century. As a result, ice caps are melting, causing sea levels to rise about 20 centimeters and increasing the number and severity of extreme weather events. The rising use of electricity is one of the causes of global warming. Data centers represent a small fraction of total electricity use, about 1% or 200 terawatt-hours per year, but they’re a growing factor that demands attention.

Powerful, energy-efficient computers are part of the solution. They’re advancing science and our quality of life, including the ways we understand and respond to climate change.

What organizations can do?

The largest gains in making IT more sustainable may be made by corporations, governments and other large organizations. Data centers, server rooms and data storage areas have a significant opportunity to run more efficiently.

In such areas, setting up hot and cold aisles is an important step toward greener computing because it reduces energy consumption and optimizes heating, ventilation and cooling. When automated systems designed to control temperature and similar conditions are combined with hot and cold aisles, emissions are further lowered. Cost savings from reducing energy use may eventually be realized, as well.

One simple step toward efficiency is to make sure things are turned off. Central processing units (CPUs) and peripheral equipment such as printers should be powered down when not in use. Scheduling blocks of time for specific tasks like printing means peripherals are only in use when they are needed.

Purchasing departments have a role to play in green computing, too. Choosing equipment that will last and consumes the least amount of energy necessary for the task to be performed are both ways to reduce the carbon footprint of IT. Notebooks use less energy than laptops, and laptops use less energy than desktop computers, for example.

The importance of being energy efficient

The heart of an eco-friendly data center beats with energy efficiency. Adopting energy-efficient technologies, including LED lighting, intelligent HVAC systems, and advanced power distribution, can significantly reduce carbon footprints. According to the U.S. Environmental Protection Agency (EPA), an Energy Star-rated data center is up to 30% more efficient. Energy efficiency isn’t just a buzzword; it’s a data center’s lifeline. Harnessing the power of renewable energy sources like solar and wind can be a game-changer. On-site renewable energy generation, combined with power purchase agreements (PPAs) with green energy providers, ensures a constant supply of clean energy. Modern cooling techniques, such as hot/cold aisle containment and liquid cooling systems, are revolutionizing data center cooling. By optimizing airflow and reducing the energy required for cooling, these methods not only save money but also contribute to a more sustainable data center ecosystem. Similarly, server virtualization and consolidation are like magic spells for energy savings. By running multiple virtual servers on a single physical server, data centers can dramatically reduce energy consumption and optimize resource usage.

6 Planning Steps For a Green Data Center

Checklist For Designing a Green Data Center

  • Determining the location
  • Making the data center energy-efficient
  • Construction with eco-friendly materials
  • Planning waste management and recycling
  • Employee training in green methods
  • Comply with all regulations

Important Equipment to Consider

To bring green data center plans to life, operators must think about acquiring a plethora of critical equipment. Rahkonen of Uptime Institute said operators must show careful consideration in selecting servers and IT equipment to “ensure high utilization for the given workloads and applications.” He said they’d also need containment systems for isolating cool from hot air as it travels in and out of the servers, adding that an “efficient cooling system” would enable operators to use “free cooling.” Something else to consider is the “adaptation of the cooling system to enable heat reuse,” according to Rahkonen. They could do this by “increasing return heat temperature to enable output to district heating system.” Rahkonen also recommends investing in “efficient electrical systems and batteries,” sensors, and a monitoring system to “measure and keep up the efficiency of all technical systems.” An efficient data center will still need to be powered and cooled by essential equipment like uninterruptable power supply (UPS) units, computer room air conditioners (CRACs) and chillers, and standby generation, according to David Watkins, solutions director at VIRTUS Data Centres. Watkins pointed out that while diesel-powered generators typically power standby generation, more sustainable methods are emerging. “A lot of research and development is underway investigating alternatives that use more sustainable fuels (hydrogen & HVO) and technologies (fuel cells and battery storage,” he said.

Green Data Centers Are Not Cheap

Although data center operators and customers can reap significant benefits from sustainable operations, critical financial factors must be considered. Rahkonen explained that while buying green data center equipment at a total cost of ownership “will typically increase the initial cost,” doing so could result in “yearly operational cost savings over time.” He said operators could also incur higher costs by buying “green electricity for direct consumption,” using the example of utility green tariffs that may include a “premium on top of regular grid electricity price.” Purchasing sensors and monitoring systems can be expensive in the short term, although Rahkonen said such technology would help operators save money from increased efficiency. They’d also be able to “compile data for regulatory reporting.” Christoph Cemper, founder and CEO of AIPRM, admits that building a green data center “can hit the wallet pretty hard at the start.” But he said the silver lining is that governments could potentially provide tax breaks or grants to help data centers achieve their sustainability goals. “And don’t forget, your energy bills will take a nosedive, which means more money stays in your pocket over time,” he added.

Blockchain Technology: A Comprehensive Overview

Blockchain Technology: A Comprehensive Overview

In the ever-evolving landscape of technology, few innovations have captured the imagination and promise of a better future quite like blockchain technology. Emerging as the backbone of cryptocurrencies like Bitcoin, blockchain has since evolved into a versatile and transformative force, poised to revolutionize industries, streamline processes, and empower individuals worldwide. In this blog, we embark on a journey to unravel the intricacies of blockchain technology, exploring its features, advantages, real-world applications, and the potential it holds for shaping the future of our digital world.

What is Blockchain Technology?

A blockchain is a distributed database or ledger shared among a computer network’s nodes. They are best known for their crucial role in cryptocurrency systems for maintaining a secure and decentralized record of transactions, but they are not limited to cryptocurrency uses. Blockchains can be used to make data in any industry immutable—the term used to describe the inability to be altered.

Because there is no way to change a block, the only trust needed is at the point where a user or program enters data. This aspect reduces the need for trusted third parties, which are usually auditors or other humans that add costs and make mistakes.

Since Bitcoin’s introduction in 2009, blockchain uses have exploded via the creation of various cryptocurrencies, decentralized finance (DeFi) applications, non-fungible tokens (NFTs), and smart contracts.

KEY TAKEAWAYS

  • Blockchain is a type of shared database that differs from a typical database in the way it stores information; blockchains store data in blocks linked together via cryptography.
  • Different types of information can be stored on a blockchain, but the most common use for transactions has been as a ledger.
  • In Bitcoin’s case, blockchain is decentralized so that no single person or group has control—instead, all users collectively retain control.
  • Decentralized blockchains are immutable, which means that the data entered is irreversible. For Bitcoin, transactions are permanently recorded and viewable to anyone.

How Does a Blockchain Work?

You might be familiar with spreadsheets or databases. A blockchain is somewhat similar because it is a database where information is entered and stored. But the key difference between a traditional database or spreadsheet and a blockchain is how the data is structured and accessed.

A blockchain consists of programs called scripts that conduct the tasks you usually would in a database: Entering and accessing information and saving and storing it somewhere. A blockchain is distributed, which means multiple copies are saved on many machines, and they must all match for it to be valid.

The blockchain collects transaction information and enters it into a block, like a cell in a spreadsheet containing information. Once it is full, the information is run through an encryption algorithm, which creates a hexadecimal number called the hash.

The hash is then entered into the following block header and encrypted with the other information in the block. This creates a series of blocks that are chained together.

Transaction Process

Transactions follow a specific process, depending on the blockchain they are taking place on. For example, on Bitcoin’s blockchain, if you initiate a transaction using your cryptocurrency wallet—the application that provides an interface for the blockchain—it starts a sequence of events.

In Bitcoin, your transaction is sent to a memory pool, where it is stored and queued until a miner or validator picks it up. Once it is entered into a block and the block fills up with transactions, it is closed and encrypted using an encryption algorithm. Then, the mining begins.

The entire network works simultaneously, trying to “solve” the hash. Each one generates a random hash except for the “nonce,” short for number used once.

Every miner starts with a nonce of zero, which is appended to their randomly-generated hash. If that number isn’t equal to or less than the target hash, a value of one is added to the nonce, and a new block hash is generated. This continues until a miner generates a valid hash, winning the race and receiving the reward.

Once a block is closed, a transaction is complete. However, the block is not confirmed until five other blocks are validated. Confirmation takes the network about one hour to complete because it averages just under 10 minutes per block (the first block with your transaction and five following blocks multiplied by 10 equals about 60 minutes).

Not all blockchains follow this process. For instance, the Ethereum network randomly chooses one validator from all users with ether staked to validate blocks, which are then confirmed by the network. This is much faster and less energy intensive than Bitcoin’s process.

Blockchain Technology

Blockchain Decentralization

A blockchain allows the data in a database to be spread out among several network nodes—computers or devices running software for the blockchain—at various locations. This not only creates redundancy but maintains the fidelity of the data. For example, if someone tries to alter a record at one instance of the database, the other nodes would prevent it from happening. This way, no single node within the network can alter information held within it.

Because of this distribution—and the encrypted proof that work was done—the information and history (like the transactions in cryptocurrency) are irreversible. Such a record could be a list of transactions (such as with a cryptocurrency), but it also is possible for a blockchain to hold a variety of other information like legal contracts, state identifications, or a company’s inventory.

Blockchain Transparency

Because of the decentralized nature of the Bitcoin blockchain, all transactions can be transparently viewed by either having a personal node or using blockchain explorers that allow anyone to see transactions occurring live. Each node has its own copy of the chain that gets updated as fresh blocks are confirmed and added. This means that if you wanted to, you could track a bitcoin wherever it goes.

For example, exchanges have been hacked in the past, resulting in the loss of large amounts of cryptocurrency. While the hackers may have been anonymous—except for their wallet address—the crypto they extracted are easily traceable because the wallet addresses are published on the blockchain.

Of course, the records stored in the Bitcoin blockchain (as well as most others) are encrypted. This means that only the person assigned an address can reveal their identity. As a result, blockchain users can remain anonymous while preserving transparency.

Features of Blockchain

  • Decentralization: Blockchain operates without a central authority, distributing control among network participants and reducing the risk of single points of failure or manipulation.
  • Transparency: Every transaction on the blockchain is recorded in a public ledger, accessible to all participants, fostering trust, and accountability within the network.
  • Immutability: Once a transaction is recorded on the blockchain, it cannot be altered or deleted, ensuring the integrity and permanence of data stored on the ledger.
  • Security: Blockchain utilizes cryptographic techniques to secure transactions and protect data from unauthorized access or tampering, making it highly secure and resistant to fraud.
  • Efficiency: Smart contracts and automated processes on the blockchain streamline transactions, reducing the need for intermediaries and minimizing delays and costs.
  • Trustless Transactions: Blockchain enables trustless transactions, meaning parties can engage in transactions without needing to trust each other, as the integrity of the transaction is guaranteed by the blockchain protocol.

Advantages of Blockchain Technology

  • Enhanced Security: The cryptographic nature of blockchain ensures secure transactions and data storage, protecting against fraud, tampering, and unauthorized access.
  • Increased Transparency: Blockchain’s transparent and immutable ledger provides visibility into transactions, fostering trust among participants and reducing the risk of disputes or errors.

This feature is particularly valuable in industries such as healthcare and supply chain management, where maintaining accurate and tamper-proof records is crucial.

Real-World Applications of Blockchain Technology

  • Supply Chain Management: Blockchain is revolutionizing supply chain management by providing end-to-end visibility and traceability. It is used for tracking products from manufacturing to delivery, ensuring authenticity and preventing counterfeit goods.
  • Healthcare: In the healthcare sector, blockchain is used for securely storing and sharing patient data, ensuring privacy and interoperability between healthcare providers.
  • Voting Systems: Blockchain-based voting systems are being developed to ensure secure and transparent elections, reducing the risk of fraud and manipulation.
  • Smart Contracts: Smart contracts are self-executing contracts with the terms of the agreement directly written into code. They automate processes and eliminate the need for intermediaries, reducing costs and increasing efficiency.
  • Digital Identity: Blockchain technology is being used to create decentralized digital identity solutions, providing individuals with control over their personal data and reducing the risk of identity theft.

Drawbacks of Blockchain Technology

  • Technology Cost: While blockchain can reduce transaction fees, it’s not without cost. For instance, Bitcoin’s proof-of-work system consumes enormous computational power, using more energy than some countries annually. Some solutions, like using renewable energy sources for mining, are being explored.
  • Speed and Data Inefficiency: Bitcoin’s slow processing time limits its transaction capacity to about 3 transactions per second (TPS), far below legacy systems like Visa which can handle 65,000 TPS. Solutions like increased TPS and Ethereum’s upgrades aim to address this issue.
  • Illegal Activity: Blockchain’s confidentiality can facilitate illegal trading, as seen with the Silk Road marketplace. While only a small fraction of cryptocurrency transactions are illicit, it remains a concern.
  • Regulation: Government regulation poses a threat to cryptocurrencies, though it’s becoming harder to shut down decentralized networks. Still, regulations can impact ownership and usage of cryptocurrencies.

Despite these drawbacks, blockchain technology offers significant benefits, including reduced transaction costs, increased security, and financial inclusion for the unbanked. However, addressing these challenges is crucial for blockchain’s widespread adoption and acceptance.

Challenges and Future Outlook

Moreover, the complexity of implementing blockchain solutions and the need for widespread adoption present additional hurdles to overcome. Interoperability between different blockchain platforms and legacy systems remains a significant challenge, requiring standardization and collaboration across industries. Additionally, the regulatory landscape surrounding blockchain technology is still evolving, with governments grappling with issues such as taxation, data privacy, and consumer protection. Despite these challenges, the future outlook for blockchain technology remains promising, with the potential to revolutionize various sectors and drive continued innovation and disruption in the years to come.

Conclusion

In conclusion, blockchain technology represents a paradigm shift in how we store, transfer, and verify data in the digital age. With its decentralized, transparent, and immutable nature, blockchain has the potential to revolutionize numerous industries, from finance and supply chain management to healthcare and beyond.

As we continue to explore and harness the capabilities of blockchain technology, we embark on a journey towards a more transparent, efficient, and inclusive future.

Augmented Reality (AR) Vs Virtual Reality (VR) 

Augmented Reality (AR) Vs Virtual Reality (VR) 

Augmented reality is an interactive experience that combines the real world and computer-generated content. Augmented reality is made up of the word “augment” which means to make something great by adding something to it. So basically, augmented reality is a method by which we can alter our real world by adding some digital elements to it. This is done by superimposing a digital image on the person’s current view thus it enhances the experience of reality.  

Augmented reality (AR) is the integration of digital information with the user’s environment in Real Time. Unlike virtual reality (VR), which creates a totally artificial environment, AR users experience a real-world environment with generated perceptual information overlaid on top of it. 

Virtual Reality (VR) 
Virtual reality is a simulated experience that employs pose tracking and 3D near-eye displays to give the user an immersive feel of a virtual world. Applications of virtual reality include entertainment (particularly video games), education (such as medical or military training) and business. 

Examples
