The passage of the Inflation Reduction Act is an important step forward in providing broad-based support for clean energy solutions over the long term. However, even in the more immediate term, and despite rallying in advance of the bill’s passage, clean energy stocks remain relatively cheap, and we see value in buying any dips as well as seeking out private exposure where possible.

On Tuesday, President Biden signed the Inflation Reduction Act (IRA), long-awaited legislation that provides significant support for clean energy development in the United States. Many clean tech stocks had already rallied in anticipation, rising 18.7% since July 27 when – to the surprise of many investors – the IRA was revived.1 This means that the final signing of this bill could actually be a “sell the news” moment for clean energy stocks, and we would not be surprised to see them fall in the near term given the magnitude and speed of the recent rally. However, looking longer term we see the IRA as a major catalyst for a re-rating the sector needed. In this week’s commentary we discuss why – despite the recent rally and especially if we see a pullback – investors may want to buy dips in clean energy.

A broad path to 40% greenhouse gas emissions reduction

The $369 billion in climate and energy provisions aims to put the United States on a path to reduce greenhouse gas (GHG) emissions by roughly 40% by 2030.2 The newly passed legislation provides incentives to decarbonize many parts of the economy, including the transport, power, industry, residential housing, commercial, and agriculture sectors (See Exhibit 1).
Exhibit 1: IRA offers a broad range of incentives across the clean energy sector

Key measures include:

  • Providing a $7,500 electric vehicle (EV) tax credit – albeit with many caveats – to help transition to cleaner transport.3 In the United States, EVs represented 6.5% of new car sales, or over 215,000 units, in the first quarter of the year, and sales are expected to reach 1.2 million in 2022, a nearly 90% year-over-year increase (See Exhibit 2).4 The IRA should help the United States close the gap on Europe and China, where EV adoption is much greater. EV sales accounted for 21.8% and 21.6% of new car sales in the first quarter in Europe and China, respectively.5 This adoption has been driven by government policies incentivizing EV sales. While the EV tax credit in the United States is a limited measure relative to policies adopted in the E.U. and China, it is a step in the right direction.6

Exhibit 2: Tax credits should help accelerate adoption of EVs in the United States

  • Extending incentives to transition to cleaner electricity generation. The Investment Tax Credit (ITC) can be applied to both residential and commercial (including utility-scale) power generation projects.7 Under the IRA, this credit is set to increase from 26% to 30% and importantly does not step down to zero until 2035.8 Previously, it would have fallen to zero by 2024.9 This ensures a longer runway of policy support, which should encourage ongoing commitments to solar-powered electricity generation. The bill similarly extends the Production Tax Credit (PTC), which had expired but has now been extended through either 2032 or until U.S. power sector emissions decline by 75% versus 2022 levels.10 The PTC applies to wind, nuclear, biomass, hydro, and solar electricity generation projects, and offers credit of roughly $26/MWh (adjusted annually for inflation) for renewable electricity generation, as long as these projects begin construction by the end of 2024.11
  • Supporting efforts to reduce emissions from the hard-to-decarbonize industrial sector. The IRA’s allocation of $13 billion for the clean hydrogen tax credit makes green hydrogen competitive with its fossil fuel alternatives.12 In fact by 2029, clean hydrogen tax credit value is expected to cover 100% of production costs for green hydrogen.13 This is important because while renewables like wind and solar can be used to make power generation cleaner, and EVs help reduce emissions in the transport sector, the industrial sector typically has to burn fuel for production. However, hydrogen can be used in oil refining, the production of ammonia, methanol, and steel, as well as in shipping and aviation.14 In addition to making clean hydrogen cost competitive, the IRA allocates $3.2 billion to carbon capture, utilization, and sequestration (CCUS).15 For example, a “grey hydrogen” solution – hydrogen derived from carbon-emitting steam reforming of natural gas – can become low-carbon “blue hydrogen” with the application of CCUS technology.16 Indeed, the demand for natural gas to create blue hydrogen is expected to grow significantly (See Exhibit 3).17

Exhibit 3: Blue hydrogen creation to boost natural gas demandA big boost for clean energy and its investors

So, the bill provides important incentives to a broad array of de-carbonization technologies, which should boost the entire ecosystem of clean energy solutions. The question is, has this all been priced in by the recent stock rally? We do not think so, and see three reasons for optimism on the clean energy ecosystem over the coming months and years:

1. The passage of this bill caught many investors by surprise. For example, according to Goldman Sachs, hedge funds long/short (L/S) positioning in the GS Renewable Energy basket stands at 90%, which is in line with historical levels.18 It is also relatively low in comparison to other growth themes such as secular growth, which has a L/S ratio of 324% or high growth/high margin equities, for which the ratio is 315%.19 Flows to the four largest clean energy ETFs have been negative over the past year, with total aggregate outflows of $545 million.20 All of which means there should be room to add exposure.

2. Valuations in the clean energy sector are not cheap, but are attractive when adjusted for earnings growth. The earnings growth of clean energy stocks is expected to outpace the S&P 500 in the next two or three years as clean energy adoption unfolds.21 For example, the three-year earnings per share compound annual growth rate for the average company in the S&P Global Clean Energy Index is 22.2%, compared with 11.3% for the broader S&P 500 Index.22 And the various incentives in the IRA should further accelerate earnings growth. Additionally, while consensus earnings revisions for the broad market index have been declining, those for renewable energy stocks have remained steady.23 As a result, on a PEG ratio basis (price-to-earnings multiple to growth), they are cheaper than the S&P 500 (See Exhibit 4).24 And a potential slowdown in rate hikes later this year should allow high growth stocks like clean energy to perform better.

Exhibit 4: Taking into account growth, clean energy stocks are cheap3. The clean energy transition is in its early days and global investment of $100-$150 trillion is needed to achieve net zero by 2050.25 Zooming out, let’s remember that renewable energy today represents only 12% of overall energy supply, but is projected to account for 28% by 2030 and 85% by 2050.26 This is driven by a global commitment to achieve net zero emissions by 2050: National governments representing 91% of global GDP have now made net zero commitments, up from 68% in December 2020.27 This should benefit a wide variety of clean energy technologies, provided by both public and private companies. In fact, the number of private clean energy companies outnumber the number of public ones by seven to one.28 As the global adoption of clean energy scales, we expect to see significant growth in revenues and profitability of the companies involved in providing key solutions.
