What are green stocks?

Green stocks are environmentally friendly stocks that appeal to investors that want their money to contribute to the planet’s future sustainability. This has become an increasingly popular way of investing as the world has become more conscious about environmental, social, and governance (ESG) sustainability.

For instance, some ESG conscious investors may only be interested in buying stocks that are committed to producing low carbon footprint and or energy efficiency through renewables, such as wind and solar power.

How will global renewable energy consumption grow?

When investing in green stocks it’s still important to diversify your portfolio. Diversification will ensure that you have a healthy basket of green stocks within your portfolio. This can help limit your exposure to risk and hopefully keep your portfolio afloat in the event of an economic downturn.

With us, you can open a CFD account to speculate on the price rise and fall of green stocks. You can also open a share trading account and invest in green stocks. This will enable you to own the green stocks outright. You can also earn dividends, if the company pays them, and have shareholder voting rights.

The company achieved the highest quarterly operating margin among all volume of original equipment manufacturers (OEMs), which it said demonstrated that EVs can be more profitable than combustion engine vehicles.2

In the same financial year, the group generated $5.5 billion in net income and $5 billion of free cash flow. This was after spending $6.5 billion to build out new factories and other capital projects. It’s ramped up production by increasing manufacturing capacity at its new factories in Austin, in the US and Berlin in Germany.

Its earnings per share were $6.95, an increase of $3.04 compared to the same period in FY20. The group said the increase reflected the gains it made on the sale of Homeowner Services Group (HOS) and a $0.40 increase in the state-controlled businesses as earnings grew from infrastructure investment, acquisitions and organic growth.6

It further stated that the increase was partially offset by an estimated $0.05 per share impact from the cooler and wetter weather in FY21, compared to the previous year.

The company reported that Q4 2021 cash and equivalents as well as marketable securities decreased to $1.8 billion from $1.9 billion in Q3 on the same year. The decrease was due to its spend on operations and capital projects in India and Ohio in the US.9

FuelCell Energy

This company manufactures fuel cell technology platforms for power generation. It offers various fuel cell products, which are used for multi-MW utility applications, microgrids and distributed hydrogen for on-site heat and chilling appliances for a wide range of products.

In its Q1 2022 financial results, the company reported that product driven revenues had increased to $31.8 million as compared to $14.9 million in Q1 2020.13

The quarterly results were negatively impacted by a non-recurring expense of $24 million related to payment of legal fees in connection to the POSCO Energy dispute settlement. There was approximately $22.2 million of backlog due to the settlement agreement with POSCO Energy. The amount represents the value of the extended warranty associated with the module order.13

The company had a gross loss of $2.9 million compared to $3.6 million in a similar period the previous year. This was while loss from operations was $44.8 million as compared to $14.4 million. Some of the gross loss was partly offset by the revenue recognised in connection with sales of modules during the quarter to Korea Fuel Cell.13

Once the company recovers from the loss from the POSCO Energy dispute settlement and clears its $1.31 billion backlog, perhaps a positive outlook may be in sight.

Financial benefits of saving the planet

Investing in green stocks doesn’t only leave the investor with a good conscience, it also contributes to environmental sustainability. Green stock investors reap monetary rewards from investing in assets that align to their values and ethics.

For instance, some investors would like to see themselves leave the earth better than they found it, ensuring future generations don’t contend with issues like global warming. Such investors would then make conscious decisions to channel their money towards ESG focused assets, with green stocks being one of them.

Like most sustainability projects, investing in green stocks takes time to yield rewards. This means its better suited for investors seeking longer term investments.

Farm the Earth: solar, water and wind energy

There are a number of renewable industries you can invest in such as wind, solar and water energy.

Wind energy uses turbines that generate electricity as the blades connected to the drive shaft rotate. Solar energy involves the radiation from the sun causing chemical reactions that in turn generate electricity. Water energy or hydroelectricity is when the natural flow of moving water is used to generate power. All of these are eco-friendly and sustainable.

You can also buy green ETFs, such as a the iShares Global Green Bond ETF, which give you great exposure to a basket of companies that promote climate change and or environmental sustainability. Note that past performance and does not guarantee future results.

Clean the planet: waste reduction, green transport and pollution controls

Sustainability has become more topical over the years as many activists and governments around the world pledge to protect the planet for the next generation. Some sustainability methods include implementing waste reduction, pollution controls and green transport systems.

Waste reduction goes beyond recycling plastic, glass and paper. It involves businesses looking for better ways to dispose and recycle of items like computer components, hazardous materials such as batteries, chemicals and oil above ground in a safe and secure manner.14,15

For instance, computers can be reduced into smaller pieces by means of a shredder then the remaining materials separated into metals and plastics before joining the traditional treatment and recycling process.14

Green transport involves reducing carbon footprint. It goes beyond walking, cycling and using public transport like the train or bus. Companies like Tesla in the US and NIO in China have seen value in green transportation and have manufactured EVs that are either solely powered by batteries or a plug-in hybrid system.

Pollution controls ensure a reduction of greenhouse gas emissions on industrial power plants, as per government mandates. For instance, some governments may impose penalties on companies producing power plants from fossil fuels like coal. Governments could also choose to incentivise companies that are reducing their carbon emissions by producing power plants that rely on renewable energy.
