The rise of renewable energy investment

Being environmentally aware has become mainstream, particularly following the Extinction Rebellion protests and Greta Thunberg's activism. This has led to the environment and climate change movement gaining worldwide traction. Events such as these have been the catalyst for transformation in the way the world stores, distributes and generates power.

By 2050, around 50% of global energy production is expected to come from wind and solar energy. As the public adopt new attitudes and behaviours for a more eco-friendly life, major energy and utility companies are investing heavily in new green initiatives. For example, Shell has spent around $2bn on investment in renewable energy since 2016.

With large companies investing in green initiatives and smaller companies developing new and innovative technologies to drive the industry forward, it's estimated that around $11.5tn will be invested into the renewable energy sector by 2050. Read more about investing in sustainable companies​.

The UK generates around a third of its electricity with renewables, predominantly split between water energy, wind energy and solar energy.

Types of renewable energy

Water energy

Water energy is a means of producing energy from falling or streaming water. Also known as hydroelectric energy, it can be generated in the form of dams, or by ocean currents. As of 2018, around 2.9% of the UK’s renewable energy was produced by hydroelectric means.

Wind energy

Wind energy involves the use of turbines to provide the mechanical power to run electricity generators. Wind power currently generates half of the UK’s renewable power and this is expected to increase as the UK aims to be carbon neutral by 2050.

Solar energy

Solar energy harnesses the light and heat from the sun. A number of complex technologies can produce solar energy, such as artificial photosynthesis and molten salt power plants, but perhaps the most recognisable is the solar panel. The UK generates around a third of its electricity from solar energy.

How to invest in renewable energy stocks

There are several ways to gain exposure to renewable stocks. These include investing in individual stocks, ETFs that track the performance of several renewable energy stocks, and renewable energy share baskets. Please note that when trading stocks, ETFs or share baskets with us, you will be trading using leverage*. Leveraged trading​​ allows you to put up an initial margin or deposit, but it's important to remember that your profits and losses are magnified based on the trade's full value, which results in a greater risk compared with unleveraged trading.

Renewable energy stocks

You can access renewable energy stocks such as Next Era, Tesla and First Solar via our trading platform. Here, you can choose to either go long and ‘buy’ or go short and ‘sell’. By playing both sides on the market, you increase the number of potential trading opportunities as you can trade on markets in both directions. Please note that a live account is needed to trade the share market; all other markets can be traded with a demo account.
