According to research company BloombergNEF (BNEF), new investment in renewable energy projects and companies totalled US$174 billion in the first half of 2021, supported by record public market financing and record levels of venture capital and private equity commitments. 

This is the highest total ever recorded in the first half of any year, and 1.8 per cent more than during the same time a year prior – although the figure is seven per cent below the high water-mark set in the second half of 2020.

The latest data on renewable energy investment in the first half of the year, as displayed in BNEF’s latest Renewable Energy Investment Tracker; and drawn from the research firm’s database of deals and projects – show that a decline in investment in new renewables projects was offset by a jump in equity offerings of renewable energy companies. 

Public market financing drives record high



New equity raised on public markets hit a record high at $28.2bn in 1H 2021, as did venture capital and private equity commitments to renewable energy companies at $5.7bn. These were major contributors to the strong overall first half. At the same time, investment in solar projects was up 9 per cent year-on-year. Wind asset finance, however, fell year-on-year, as it stands in contrast to 1H 2020, which was a bumper period for financings of major offshore wind farms.


“Renewable energy investment has withstood the effects of the global pandemic, in contrast to other sectors of the energy economy where we have seen unprecedented volatility,” noted Albert Cheung, head of analysis at BloombergNEF. “However, a 1.8-per-cent year-on-year increase is nothing to write home about. An immediate acceleration in funding is needed if we are to get on track for global net zero.”

Wind project installations surge in China and US



Wind project investment in the first half topped $58bn, matching levels seen in 2018 and 2019, but was a notable reduction from the $85bn invested in the same period last year.

In 2020, installations surged in China and the US ahead of subsidies lapsing. Investment in China – the world’s largest wind market – was robust at $21bn in 1H 2021, showing that developers are continuing to build projects without feed-in premiums. 

EMEA accounted for 36 per cent of wind project investments. Europe had a strong first half, with Finland emerging as the top onshore market. RWE’s Sofia Offshore Wind Farm reached financial close as one of the cheapest projects in the UK, at $2.9 million per megawatt.



Record high for solar projects in H1

Investment in solar projects rose to a record $78.9bn in the first half of 2021. Solar projects in China garnered $4.9bn in Q2 2021, up from $2.8bn in the first quarter. The increase was largely driven by major financings of gigawatt-scale ‘subsidy-free’ projects developed by state-owned enterprises like China Energy Investment Corp. and Huanghe Hydropower, which must be commissioned this year. 

Large-scale solar project investment in the US rose to $6.4bn in Q2 2021, from $5.3bn in the first quarter, driven by a number of large projects closing. Solar project investment often accelerates in the second half of the year to meet end-of-year deadlines.

Public market financing up 509% from last year



So-called ‘funds in circulation’, which includes the refinancing of renewable energy projects, mergers, acquisitions and buyouts, totalled $68.3bn in H1 2021, up almost 18 per cent from a year earlier. The first half saw the highest ever total for equity raised on public markets by clean energy companies, outpacing the volumes raised in any previous year. A bull run for clean energy shares enabled many companies to issue new shares to finance growth – though valuations are now down from their highs at the start of the year.



Renewable energy and related companies raised a total of $28.2bn on public markets in the first half, up 509 per cent from last year. Among the largest share offerings, Chinese renewable energy generator China Three Gorges Renewables raised $3.5 billion, PV manufacturer Longi Green Energy Technology raised $2.4bn, and US fuel cell company Plug Power pulled in $2bn.

Strength of appetite for sustainable investment


“As the energy transition accelerates, investors are increasingly looking for ways to increase their portfolio exposure to renewable energy and related areas, such as energy storage and hydrogen,” noted Logan Goldie-Scot, head of clean power at BNEF. “This record first half for clean energy fundraising underlines the strength of appetite for sustainable investment opportunities aligned to a net zero future.”



Merger and acquisition activity is an important part of the renewable energy financing picture, although these deals are not included in BNEF’s overall new investment figures as they do not provide new money for technologies and developers. In H1 2021, corporate M&A and private equity buyouts totalled $22.4bn, up 25 per cent on the previous year’s $17.9bn. India outpaced the US and China, which were the leading markets of 2020.

In January 2021, BNEF published a report titled Energy Transition Investment Trends concluding that the world invested more than $500bn in the energy transition in 2020. The annual Energy Transition Investment Trends report covers investment across multiple sectors, including renewable energy, electrified transport, electrified heat, hydrogen and carbon capture, but is focused only on investment in projects or deployments of technology. In contrast, this report – the Renewable Energy Investment Tracker – has a narrower sectoral scope, focusing primarily on renewable energy, but also adds in corporate fundraising for renewable energy companies. Although the data is cut differently, both reports draw on the same underlying data gathering processes and teams within BloombergNEF.
