Green Energy
Electricity is a Dominant Theme in Green Energy Because Electricity is the Common Thread and Form in the New Sustainable Energy Economy. Some Key Sources:
Photovoltaic Solar Electricity (“PV”) Wind Electrical Energy Solar Thermal Electrical Generation Electrical Energy Efficiency (EE), and …

The Opportunities
Most Compelling: COST SAVINGS. Numerous Opportunities; Some Applications:
Distributed Solar PV for Homes, Businesses, and Institutions
Energy Auditing of Buildings Applying Energy Efficiency Measures to
Buildings Such as Highly Efficient Lighting and Lighting Control Systems

Energy Audits are 1st Because We Need to Understand the Facility, its Energy
Related Systems, Usage, and Costs BEFORE We Make Any Changes. Make Sense?
Would You Like Your Doctor to Operate on You Without Tests and Diagnosis?
If Your Car is Running Poorly Should the Engine be Replaced Before it is Diagnosed?
And Then … Should the Most or Least Expensive Measures be Considered First?

Makes Perfect Sense, Yet … Solar PV Jobs and Other Energy Related Retrofit
Work is Often Done Without First Doing a Comprehensive Facilities Energy Audit
Prospective Energy Savings are Not always Being Realized to Full Potential Because Property Owners and Managers Do Not Always Have All the Energy Information they Need to Make the Best Decisions
The Energy Audit is the Diagnostic Tool that Provides the Comprehensive Data Required to Reduce Costs and Obtain the Best Return on Investment
GREEN ENERGY

And Energy Efficiency is a Key Factor
Facility Energy Efficiency (EE) is Making Interior and Exterior Electrical, Mechanical and Building Envelope Systems Work in a Highly Efficient Manner.
Many EE Measures are Less Expensive Than Providing More Power from the Grid or from Distributed Generation.
The Least Expensive Kilowatt is the One We Don’t Use!

Why Energy Audits?
$Billions in Federal Stimulus for EE projects
Utility, and State incentives for EE projects
EE Costs Only 2.5 - 3.0 Cents / KWH

About Energy Assessments
Goals of facility energy assessment:
Find likely opportunities to save energy and save money
Maybe retrofit or replace equipment
Make informed decisions

Why Energy Assessments?
Identify high-return energy efficiency upgrades:
Reduce energy/overhead costs
Improved Operational Efficiency
Increase productivity via better indoor environment

National Energy Conservation Mandates
There are Federal and State Mandates to reduce energy consumption California Investor Owned Electric Utilities are
ordered to save around 3 Billion kWh’s each year from 2007-2113
Federal buildings ordered to reduce electrical energy consumption 35% by 2012
