Lean Energy Engineering: A New Frontier for American Industry.
- 1. Lean Energy Engineering ReducingWaste, Boosting Productivity — A New Frontier for American Industry Presented by: Tahmidul Islam Industrial & Systems Engineer | Lean Practitioner | Engineering Management (USA)
- 2. Why we shouldconcern… •Energy waste is silently hurting U.S. productivity •Engineering-led solutions offer fast, measurable impact •Time to rethink energy as a performance factor
- 3. Why This Matters:Energy as a Hidden Productivity Lever •30% of energy in factories is wasted (DOE, 2023) •Energy is often seen as a fixed cost, not an input •This mindset limits growth and competitiveness
- 4. The Productivity–Energy Connection •Productivitylosses often trace back to energy misuse •$50B/year wasted in avoidable inefficiencies (EIA, 2023) •Most plants track output/labor — not output/kWh
- 5. Strategy #1 –Lean Energy Mapping •Add energy data to value stream maps (VSM) •Identify high-energy, low-value steps •Use low-cost upgrades (e.g., VFDs)
- 6. Strategy #2 –Real-Time Monitoring & Smart Sensors •Track energy by machine/shift in real time •Identify idle-time power consumption •Enable auto shut-off and alerts
- 7. Strategy #3 –Energy-Efficient Layout Design •Optimize equipment and flow for less travel •Reduce HVAC load and unnecessary motion •Align physical layout with energy flow
- 8. Strategy #4 –Strategic Equipment Upgrades •Target high-energy machines (e.g., compressors) •Use ROI-based upgrade planning •Focus on fast payback improvements
- 9. Strategy #5 –Behavior-Based Energy Management •Train workers on shutdown and reporting habits •Use KPIs and incentive programs •Create an energy-aware culture
- 10. Quick Comparison –Strategies at a Glance •Mapping: Adds energy to value streams •Monitoring: Enables real-time decisions •Layout: Reduces indirect energy load •Upgrades: ROI-based retrofits •Behavior: Sustained performance via people
- 11. U.S. Industry ExamplesThat Prove It Works •U.S. plants are already achieving results •Mix of tech + people = real efficiency gains •Mid-sized firms benefit most from fast ROI
- 12. Case Study –General Motors •Saved $100M+ from 2010–2020 •Used smart meters + staff training •20% electricity cut at one Tennessee plant
- 13. Why Engineering ManagersMust Lead This Shift •Energy impacts cost, speed, and reliability •Managers can drive change with existing tools •Leadership needed more than large investments
- 14. Closing Thoughts &Call to Action •energy is a productivity lever, not just a cost •Small changes → big operational gains •Start with data, flow, and people

Editor's Notes
- #2 This presentation explores how U.S. manufacturers can reduce energy waste through lean engineering strategies — without major capital investment.
- #3 Manufacturers who treat energy as a controllable resource, not just overhead, gain an edge in cost control and operational performance.
- #4 Energy and productivity are interconnected. Aligning both leads to smarter planning and stronger margins in manufacturing.
- #5 Lean energy mapping helps uncover hidden energy drains, enabling targeted improvements without disrupting flow.
- #6 Smart sensors make energy use visible and actionable, helping factories reduce waste and respond faster to inefficiencies.
- #7 Small layout changes can lead to significant energy savings, especially in HVAC and material handling-intensive operations.
- #8 Investing in energy-efficient equipment doesn’t have to be expensive — strategic retrofits offer fast returns and long-term savings.
- #9 Technology alone isn’t enough — consistent worker behavior is key to sustaining energy performance over time.
- #10 Each strategy plays a unique role in reducing energy waste. Together, they form a comprehensive energy management approach.
- #11 Energy efficiency isn’t theory — it’s already delivering cost savings, emissions reduction, and reliability in U.S. manufacturing
- #12 GM’s multi-site energy strategy combined tech upgrades with employee engagement, delivering measurable results across its U.S. operations.
- #13 Engineering managers are best positioned to link energy performance to operations — and lead practical, high-impact change.
- #14 Energy efficiency doesn’t require massive overhaul. With the right mindset and engineering approach, real results are within reach.
