How to play the clean energy revolution

When the wind blows and the sun shines, we get paid.

These are two events that make us happy and help to explain why close to 30% of the Sanlam Real Assets fund is currently invested in renewable energy assets. It is a sector that has experienced significant change over the past 10 years – and one that we expect will make further progress over the next few decades.

For example, solar energy module costs have decreased by 84% since 2010 – and they are forecast to fall by a further 52% over the next seven years.[1] Likewise, wind energy has become cheaper: turbine costs have fallen by 32% since 2010.[2] While global demand for clean energy continues to grow, solar and wind energy production have become cheaper than coal and gas across a number of major markets. By 2050, it is estimated that wind and solar will account for close to 50% of the world’s electricity supply.[3]

The clean energy revolution is well under way – and this represents a theme that we are playing in the Sanlam Real Assets fund. After years of subsidies, renewable energy is on the verge of becoming self-sufficient. This could represent a significant milestone for the sector in the not-so-distant future. For example, the UK could start to host onshore wind and solar projects subsidy-free from the early 2020s.[4]

We invest primarily in operational assets (rather than those in development) for the simple fact that we want to get paid when the wind blows or the sun shines. Our investments provide exposure to onshore and offshore wind, solar, hydro assets, anaerobic digestion, biomass and landfill gas through companies based in the UK, Europe, Asia and America.

These investments produce a stable cash flow and a healthy income stream via regular dividends. What’s more, there is a level of predictability in the cash flows they provide: the sun continues to shine and the wind blows. They also offer a degree of inflation protection over the long-term because the subsidy regime is inflation-linked. There is much to be said for this in the low interest rate environment we find ourselves in today, particularly with inflation above 2%.

Looking ahead, the sector is likely to experience further change. Battery prices have fallen by 79% since 2010, which represents a significant development for renewable energy production.[5] As Battery storage becomes commercially viable renewable energy producers will be able to deliver clean wind and solar energy even when the wind isn’t blowing and the sun isn’t shining. We would expect to see further improvements to renewable energy production, monitoring and maintenance on the back of technological developments.

It’s incredible to think how far the renewable energy sector has come in a relatively short space of time. Ørsted estimates that an 8MW turbine – the V164-8.0MW produced by MHI Vestas – is able to generate enough electricity in one revolution to power a house for 29 hours. Walney Extension, the UK’s newest and largest operational wind farm, currently hosts 40 of these turbines.

The renewable energy sector has already come a long way, but we believe the clean energy revolution still has a long way to go.
