With more countries across the world passing legislation to accelerate decarbonisation to combat global warming, interest in investing in green energy stocks is growing.

In early November 2021, the US Congress passed the Bipartisan Infrastructure Deal (Infrastructure Investment and Jobs Act), which is part of US President Joe Biden’s Build Back Better plan. The act has been billed as a once-in-a-generation investment in the country’s infrastructure.

Under the act, $7.5bn (£5.59bn, €6.69bn) will be invested to build a national network of 500,000 electric-vehicle (EV) chargers in the country and to support the president’s desire “to accelerate the adoption of EVs, reduce emissions, improve air quality, and create good-paying jobs across the country”.

Government policy, coupled with extreme weather caused by climate change, has expedited the development of renewable energy globally. The International Energy Agency (IEA) said in its World Energy Outlook 2021 report:

“A new energy economy is coming into view, ushered forward by policy action, technology innovation and the increasing urgency of the need to tackle climate change.”

According to the IEA, clean energy will become a major new area for investment and international competition. It said:

“If the world gets on track for net zero emissions by 2050, then the annual market opportunity for manufacturers of wind turbines, solar panels, lithium-ion batteries, electrolysers and fuel cells grows tenfold to $1.2trn by 2050.”

The IEA believes the five elements above could generate more revenue than today’s oil sector and its downstream industry.

Types of renewable energy

Much of the world’s renewable energy is for electricity generation. Unlike burning fossil fuels for power generation, renewable energy has a low carbon footprint, which is why it is referred to as green energy.

Solar, wind and hydroelectric power generation are some of the more well-known and mainstream types of renewable energy.

Type of renewable energy

How it works


Flowing water is used to drive turbines to generate electricity. Hydropower plants consist of dams and reservoirs. Hydropower dams with a large reservoir can store water over short or long periods to meet peak demand.


Wind energy is used to drive wind turbines connected to generators, thereby producing electrical energy through electromagnetism.

Solar photovoltaic

Photovoltaics (PV), also called solar cells, are electronic devices that convert sunlight directly into electricity.

Solar thermal

Concentrated solar power (CSP) uses mirrors to focus solar rays that heat fluid to create steam for driving turbines and generate electricity. CSP is used to generate electricity in large-scale power plants.

Top renewable energy stocks to watch

Some of the best clean energy stocks could be of those companies that focus on renewable energy, as the carbon footprint of those operations would be lower.

Before you decide what green energy stocks to buy, let’s look at some of the top alternative energy companies’ stock by market capitalisation. According to CompaniesMarketCap, the top five companies by market cap are LONGi Green Energy Technology, Adani Green Energy, Vestas Wind Systems, Brookfield Renewable Partners.

The difference between trading assets and CFDs
The main difference between CFD trading and trading assets, such as commodities and stocks, is that you don’t own the underlying asset when you trade on a CFD.
You can still benefit if the market moves in your favour, or make a loss if it moves against you. However, with traditional trading you enter a contract to exchange the legal ownership of the individual shares or the commodities for money, and you own this until you sell it again.
CFDs are leveraged products, which means that you only need to deposit a percentage of the full value of the CFD trade in order to open a position. But with traditional trading, you buy the assets for the full amount. In the UK, there is no stamp duty on CFD trading, but there is when you buy stocks, for example.
CFDs attract overnight costs to hold the trades (unless you use 1-1 leverage), which makes them more suited to short-term trading opportunities. Stocks and commodities are more normally bought and held for longer. You might also pay a broker commission or fees when buying and selling assets direct and you’d need somewhere to store them safely.
