Cleantech Is More Than Just Renewable Energy

By Aaron Levitt | Updated September 02, 2014 AAA

Generally, when investors tend to think about green investments, renewable energy sources like solar and wind are the first thing that pop into their minds. As such, these “sexy” growth opportunities often command the lion share of investment dollars. That’s evident by the surge in assets under management in popular ETFs like the iShares Global Clean Energy (NASDAQ: ICLN).

Yet, there’s more than one way to skin a cat.

And in terms of green investing, the boring concepts of energy efficiency and pollution remediation could actual make portfolios more money over the longer haul than sexier solar and wind power. For investors, there’s a wide world of cleantech ripe for the picking.

Focusing On The Low Hanging Fruit

As the world's population continues to increase at a rapid pace, so does the pressure being placed on our planet. With these growing demands for energy and commodities consumption, many investors are looking towards technology as a way to mitigate these challenges.

Enter cleantech in all its glory.

While renewable energy does fit under the cleantech umbrella, the concept is much more than just solar panels and biofuels.  As a widely diverse segment of technology, cleantech is used to describe products and services that improve productivity or efficiency while reducing costs, inputs, energy consumption, waste, or pollution. This wide net includes everything from energy efficiency and recycling efforts to pollution controls. 

And spending on the non-renewable side of cleantech is rising quite quickly.

With energy usage expanding rapidly, many business and governments have turned towards energy efficiency measures to save money over the longer haul. Using less can actually be a smart strategy to grow corporate profits. And with the U.S. Department of Energy (DOE) reporting that buildings account for nearly 70% of the nation's electricity demand, spending on smart HVAC systems, high-efficiency lighting and installation continues to rise. According to the DOE, spending by private businesses and homes on energy efficiency will double by 2025 to hit more than $9.5 billion per year. 

At the same time, one of the nasty side effects of quickly expanding economic growth is pollution.

Throughout history, almost no country that has risen to be a major industrial power, has done so without creating widespread environmental damage. In the developed world, we’ve started to seriously consider what we’ve done in the past and “green” now factors into many businesses decision making processes. Meanwhile, nations in the emerging world are beginning to seriously consider pollution as well. The total global air pollution mitigation market has grown by a compound rate of nearly 10.6% over the last six years, while global spending on water pollution will surge to $1.2 trillion by 2025. 

Playing the Total Cleantech Package

These few examples show just how big cleantech is and is getting. For investors, that means casting a wider net beyond just solar stocks- like First Solar (NASDAQ:FSLR) -could lead to more portfolio profits over the long haul. A great starting place is the PowerShares Cleantech (NYSE:PZD).

The ignored fund tracks a wider range of green technology firms than its more popular sister ETF- the PowerShares WilderHill Clean Energy (NYSE:PBW). That includes exposure to grid firms like ABB Limited (NYSE:ABB) as well as lighting specialist Cree (NASDAQ:CREE). That broad focus has actually allow PZD to outperform its renewables-only rivals by a wide margin. Expenses for the ETF run 0.67%. 

Water sanitation continues to be a paramount issue and carbon filters are some of the most effective methods at removing chlorine, sediment and other volatile organic compounds from water. Calgon Carbon (NYSE:CCC) is one of the largest manufacturers of activated carbon and filtration systems in the world and has been growing its market shares in places like India and China. In addition, Pall (NYSE:PLL) can be used as a water filtration/sanitation play.

Finally, smart heating and cooling systems spending has jumped over the last few years as businesses try to cut long term energy costs. Johnson Controls (NYSE:JCI) continues to be the building retrofit king-pin- registering 8.6% growth in 2013. Overall, management at JCI expects continued new construction gains in the U.S. to help its smart HVAC systems grow its bottom line.  JCI shares can be had for forward P/E of just 12. 

The Bottom Line

Cleantech is much more than just “sexy” renewable energy like solar and wind. Covering a wide range of ideals, spending in the sector is poised to continue growing in the years ahead. That might just grow investor’s portfolios as well. The previous ideas- along with smart grid play Digi International (NASDAQ: DGII) –make ideal selections to play the trend.
