This presentation explores the core principles and importance of Green Computing. It highlights how environmentally responsible use of technology can reduce energy consumption, electronic waste (e-waste), and carbon emissions. The slides cover key concepts like energy-efficient hardware, virtualization, and renewable energy use in data centers. Real-world examples from companies like Google, Apple, and Dell are included, along with practical challenges and user-level solutions. The goal is to raise awareness and encourage sustainable practices in computing.

1. Green Computing and Energy-
Efficient Technology
A University Presentation

2. Introduction
• Green Computing = environmentally
responsible use of technology
• Focus: reduce energy usage, e-waste, and
carbon emissions
• Important due to climate change and growing
tech demand

3. Key Concepts
• Energy-efficient hardware: CPUs, SSDs, low-
power devices
• Cloud computing and virtualization to reduce
resource use
• E-waste management and recycling strategies

4. Technologies and Strategies
• Power management: sleep mode, hibernation,
shutdown tools
• Green software: optimized for less processing
• Use of renewable energy in data centers

5. Real-World Examples
• Google: Carbon-neutral data centers since
2007
• Apple: 100% renewable energy in offices,
efficient M-series chips
• Dell & HP: EPEAT-certified devices for eco-
friendliness

6. Challenges
• High initial cost of green tech
• Lack of user awareness and incentives
• Technical limitations in older infrastructure

7. How You Can Contribute
• Turn off unused devices and enable power-
saving settings
• Use cloud services efficiently
• Recycle e-waste properly and choose energy-
efficient products

8. Conclusion
• Green computing is vital for sustainable tech
growth
• Tech industry plays a key role in reducing
emissions
• Every user’s behavior counts in creating a
greener future
