Energy Efficiency Investments Out-Perform Dow Jones Index
EE Beats Wall Street
Many of us have seen greater returns on our 401K accounts and other stocks during the past 2 years. However, no one can guarantee that such performance is going to continue. In fact – the stock market could drop suddenly and there is little you could do about it.
We have zero control over Wall Street’s performance. Beyond that fact, a typical energy project (in which you do have some control) is a better investment anyway! The example below compares the Dow Jones Index’s performance for the past 10 years versus a typical energy efficiency project that yielded a conservative 5-year simple payback (or 20% Return on Investment), which is easy to find.
Here is the year by year comparison of value if you invested $1 and then re-invested the gains each year (either into additional energy projects or the Wall Street Fund):

At the end of 10 years, the Energy Project would have yielded $6.19 for every dollar invested (net gain of $5.19), while the DJI would have yielded only $1.86 for every dollar (net gain of $0.86).
Suppose we consider an alternative comparison and we remove the year 2008, because that was a “bad year” for Wall Street. In this case (below) the Energy Project would still have yielded $5.16 for every dollar invested (net gain of $4.16), while the DJI would have yielded only $2.82 for every dollar (net gain of $1.82).

If you look objectively at the data… Energy Projects beat Wall Street overall and they beat Wall Street in 8 out of the last 10 years… and we aren’t even accounting for the fact that most EE projects carry very little risk!
Additional Considerations
To be fair- perhaps your company has projects or business processes that return greater than 20%. In that case- great! You should put your money there… but don’t forget to ask if those non-energy projects will get those returns every single year… because the energy projects will.
In fact- energy projects will likely save additional monies as utility prices fluctuate. In addition, by using less energy, your company is less vulnerable to utility price spikes.
As I have written about in past articles, you could also present the savings as “avoided costs”, such that if you didn’t do the energy project, you would be “throwing away” the net benefit ($5.19) on wasted energy bills.
You could also relate back to research I did about 20 years ago, which shows that a company’s stock price increases significantly (by 21% above market) when that company announces an energy project. That study was done with a confidence interval of 95%, and your company’s CFO may be very interested in reading that paper.
Conclusion
I want to restate that when comparing “apples to apples” investment-wise, the low-risk Energy Efficiency Projects perform better than Wall Street Investments.

07.10.2018 Interview with Eric Woodroof
What got you interested in energy management?
While watching “Dances with Wolves”, I wanted to do something that “helped” our environment. After wars… energy consumption has had the most destructive impact on our planet… so it seemed like a problem worth devoting my life to.
How have things changed since you started working with energy management?
The “information age” and renewable energy advancements have made for cleaner energy production, yet there is still a long way to go… but at least more people are aware of the problem.
What does sustainability mean to you?
Providing the needs of today… without sacrificing tomorrow.
What are your biggest goals in your life/career currently?
I would like to see more energy efficiency/conservation projects get done… when people understand how easy it is, they are better able to take action. Most projects have financial returns that are 2-3 times better than Wall Street… and have less volatility!
Who is your role model?
Al Gore has done a lot to share climate data, and for little economic gain… I find that admirable.
How much does humor factor into your keynotes and other speaking engagements?
Humor is a critical “ice breaker” on these difficult topics/challenges. Often in talks, I will engage an audience with humor, then depress them with the data… but then lift them up by showing how they can be a part of the solution… but humor throughout the journey keeps them listening.
