Efficiency & Energy Economics

Saving energy and valuing investments. Pumps and system efficiency, energy audits and management, engineering economics, LCOE and energy policy.

• Pumps — Pumps add energy to liquids. Learn centrifugal vs positive-displacement pumps, head, flow and hydraulic power, pump and system curves, efficiency, affinity laws, NPSH and cavitation, and series/parallel operation.
• Energy Efficiency, Audits & Energy Management — The cheapest energy is the energy you don't use. Learn energy audit types and methodology, specific energy consumption and benchmarking, efficient motors and VFDs (affinity laws), pumps, fans and compressed air, lighting, HVAC and chillers (COP, EER), degree-days, boilers and steam systems, waste-heat recovery, power factor, ISO 50001 energy management and measurement & verification — with Python for motor, VFD and cooling savings.
• Engineering Economics & Investment Decisions — Deciding whether projects are worth it. Learn the time value of money, simple and compound interest, cash-flow diagrams, present/future/annual worth, NPV and discount rates (MARR), IRR, payback and discounted payback, benefit–cost ratio, comparing alternatives with unequal lives, depreciation (straight-line, declining balance), taxes, inflation, break-even and sensitivity analysis — with Python evaluating an automation investment.
• Energy Economics, LCOE & Energy Policy — What energy really costs. Learn capital and operating costs, the capital recovery factor, levelised cost of electricity (LCOE) and its sensitivity to discount rate and capacity factor, system costs of variable renewables, tariffs and power purchase agreements, merit order and electricity markets, subsidies and carbon pricing, energy policy in India (renewable targets, PAT, green hydrogen mission) and energy access — with Python comparing solar and coal LCOE.
