Is wind energy a good long-term investment? Absolutely yes, I believe wind power represents an opportunity for stable returns over the decades ahead.
Having covered the energy industry for over a decade, I’ve seen firsthand how quickly wind technology has improved and costs have fallen to be the most affordable renewable electricity source.
Just 5 years ago, critics would scoff saying intermittency made wind unsuitable for major grid supply roles. Fast forward to today however and countries like Denmark, the UK, Uruguay are already seeing days where wind generates most power needs.
In this comprehensive guide, we’ll explore wind energy’s growth trajectory, the economics behind projects, models for investing, and the key factors that could impact returns over the years to come. Whether you’re an individual investor considering greener opportunities or an institution weighing the renewable sector, a deep dive into wind power can help inform decisions. There are certainly short and long-term complexities, but compelling tailwinds remain that can be captured.
Tailwinds Driving Growth in Wind Power
Wind energy has cemented itself as one of the lowest cost and scalable renewable energy technologies available today. Costs have fallen dramatically thanks to technology improvements, economies of scale, and fierce competition amongst industry players.
Government incentives have also accelerated deployment. These factors along with rising energy needs and corporate demand have paved the way for impressive growth.
Falling Costs Making Wind Cost-Competitive
The costs associated with developing wind farms have dropped by over 70% in the last decade according to AWEA. Turbines themselves have seen costs fall by 40% since 2010.
These stark declines have made pricing extremely competitive with traditional energy generation. In many areas, signing long term Power Purchase Agreements (PPAs) linked to new wind projects is now cheaper than continuing to buy fossil fuel supply.
| Year | Average PPA Price Per kWh (USD |
| 2009 | $70+ |
| 2019 | $20-40 |
Government Incentives and Policy Support
The regulatory environment has also fueled rapid expansion plans by energy developers. Tax credits like the PTC in the U.S. along with state renewable energy incentives and portfolio standards have facilitated tens of billions invested into the American wind industry.
Europe has been even more ambitious with programs like EU’s “Fit for 55” package targeting major emissions cuts this decade through clean energy builds. Government support de-risks projects for large developers and tilts investment momentum strongly in wind’s favor in key markets.
Corporate Renewables Procurement Driving Demand
Some of the largest companies in the world have also made major renewable energy commitments to reduce greenhouse gas footprints. Google, Amazon, Apple, Unilever, and many others are signing huge renewable PPAs from operators like NextEra Energy to power data centers and other facilities.
BloombergNEF estimates corporate renewable energy procurement could triple by 2030. This provides a stable base of multi-year contracted demand for wind developers to leverage and expand portfolios.
The Investment Bull and Bear Case for Wind Energy
All this growth begs the question – what exactly makes wind energy such an attractive investment proposition from here? In a nutshell:
Bull Case
- Stable, predictable returns through 20+ year PPAs
- High energy demand across residential, commercial, industrial uses
- Long asset life of wind equipment, low maintenance costs
- Continued cost declines, efficiency gains through better turbine tech
Conversely, some risks could hamper that upside potential:
Bear Case
- Declines in fossil fuel market pricing impairing cost-competitiveness
- Grid connectivity and stability challenges at high wind penetration
- Periods of tax credit uncertainty or incentive pull-backs
- Suitable land constraints for new projects
There are also some myths around wind variability and reliability that skeptics have raised. However, energy forecasting methods along with grid interconnections over larger regions have mitigated most of these concerns for major operators.
Models for Investing in Wind Power
If assessing wind energy investments, what are the main options or models out there to consider?
Investing in Utility-Scale Wind Farms
The predominant model is investing equity or debt into a specific wind farm project site. These can be in the hundreds of megawatts scale with dozens of individual turbines. Revenues come from the 20+ year PPAs signed with utilities, corporations, governments. Top operators like NextEra, Iberdrola, Ørsted have extensive portfolios across North America, Europe, Asia Pacific.
Public Stocks and ETFs
Rather than picking single projects, investors can get exposure to the broad wind energy industry through public stocks and ETFs. Top wind companies like Vestas Wind Systems, Siemens Gamesa, GE Renewables are major turbine manufacturers and developers. Brookfield Renewables, Northland Power also specific renewable yieldcos.
Emergence of Distributed and Community Wind Projects
Historically wind farms have been these massive utility scale builds. But there’s an emergence of smaller scale distributed wind projects thanks to modular turbine tech improvements and grid connectivity solutions. Governments provide incentives for community-owned wind in rural areas or rooftop/vertical axis turbines for residential buildings. The returns can be higher albeit on much smaller individual investments.
Key Factors Impacting Future Returns
Clearly the growth trajectory and economics look solid. But what could disrupt that outlook or what trends could enhance the return potential from here?
Cost and Efficiency Outlook
The wind industry has consistently beat cost decline and performance improvement projections. The International Renewable Energy Agency (IRENA) forecasts that onshore wind energy costs per kWh could plunge a further 15-35% by 2025 thanks to:
- Oversized rotor blades and hub heights that capture faster wind speeds
- Increased nameplate capacity factors from improved efficiency
- Cheaper but reliable materials
- Emergence of bladeless wind turbine concepts
These gains will be crucial to long term profitability improvements for investors.
Evolving Policy Landscapes
Governments play a pivotal role in nurturing renewable energy growth through incentives like PTCs and setting ambitious energy targets. Most analysts see governments maintaining this high level of support. However sudden tax credit expirations or failures to extend targets would negatively impact investor returns.
There’s also a longer term possibility of wide-scale carbon pricing programs. This would directly improve the cost competitiveness of wind against gas and coal alternatives. But near-term prospects remain mixed across Asia, Europe and North America.
Grid Integration Capabilities
Modern power grids have proven able to handle over 50% instantaneous wind power penetration without stability issues. But some grid operators are still gradually moving to evolve operating protocols, upgrade transmission capacity between regions, and pilot grid-scale battery solutions to manage the variability as wind reaches over 30-40% of total supply. Investments will be needed over the 2020s in ancillary stability services to open up additional share for cost-effective wind.
On the flip side, excess wind energy that gets curtailed during times of lower demand or congestion also chips away at profitability. So optimizations in this area are in all developers best interests.
