Our Methodology for Selecting the Best RNG Stocks

Choosing the best renewable natural gas (RNG) stocks to invest in isn’t as simple as picking ones that produce a healthy return on investment. Profits are important, but so is knowing that each investor has a unique personality and goals. With that in mind, we created a methodology with these considerations. 

Risk Tolerance

Volatility may not faze one investor, but it will give another an ulcer. Since risk tolerances can run the gamut, we included stocks with low betas, a sign of little volatility, as well as ones that are aimed at growth but may have some ups and downs. 

Time in the Market

An investor may plan to buy and hold an RNG stock for decades, while another will plan to use their funds in the short term to start their retirement or send a child to college.

For this reason, we chose a variety of stocks, including riskier stocks that will grow over time and conservative and well-diversified options that would be safer closer to retirement. 

Investor Activism

Some investors want their money to make a statement as well as a profit. Those investors might balk at investing in a company known for fossil fuels even if that company is expanding into renewable natural gas. 

Stocks vs. ETFs

Having a diversified portfolio has never been easier. Rather than buying shares of just one stock, investors can now buy shares in exchange-traded mutual funds that will expose them to multiple companies in one sector or across various sectors. We included a few exchange-traded funds with exposure to RNG companies. 

Passive Income

Some investors seek a dividend yield for income or reinvestment to grow their portfolios. RNG stocks with solid yields are in our renewable natural gas roundup.

Analysts’ Ratings

Wall Street analysts rated our selection of renewable natural gas stocks and ETFs. We focused on options rated “strong buy,” “buy,” and “hold,” giving you top options for portfolio additions related to RNG.

Multiple Sectors

Our choices include stocks in energy, clean energy, utilities, and more.

What is Renewable Natural Gas? 

Renewable natural gas is pipeline-quality biogas that can be used interchangeably with conventional natural gas. Since biogas is a product of the natural decomposition of organic matter, RNG can come from landfills, livestock operations, anaerobic digestion, or thermochemically. 

After the gas is collected, it’s processed to remove water, carbon dioxide, hydrogen sulfide, and other trace elements, leaving pure methane. 

RNG can be converted into compressed natural gas (CNG) or liquefied natural gas (LNG), which can be used as a transportation fuel. The U.S. Renewable Fuel Standard lists RNG as an advanced biofuel and is considered a form of renewable energy.

Different Types of RNG Collection

Landfills

RNG is collected from landfills – where the trash you set by the curb weekly goes – is known as landfill gas or LFG. Landfills are the third-largest source of human methane emissions in the U.S. Most LFG is used to produce electricity. 

Livestock operations

Biogas can also come from heating the manure associated with livestock operations. The RNG from this source tends to go towards powering natural gas vehicles.

Wastewater treatment plants

RNG can also originate from wastewater treatment plants. This energy could potentially produce up to 12 percent of America’s electricity.
