Will Democrats’ midterms triumph put wind back in sails of the renewables sector?

Future brightens for US developers in particular after election when voters rejected Trump’s war on clean energy

After years as collateral damage in Donald Trump’s war on climate action, the Democrats’ sweeping triumph in the US midterm elections has emerged as a victory for the global renewable energy industry too.

Across the world’s financial centres the market value of renewable energy developers climbed as the election results confirmed the Republicans had lost control of the Senate and House of Representatives.

For the world’s largest offshore wind developer, Ørsted, the shift in power could spell a reprieve from the White House’s assaults on the Danish company’s multibillion-dollar offshore wind investments off the north-east US coast.

Ørsted’s market value jumped by almost 10% within hours of the Democratic victory, before closing nearly 5% higher. The share price of other European renewables companies active in the US also climbed. Portugal’s EDP Renewables and the French utility Engie rose by more than 3%. Shares in Germany’s RWE added about 1%.

The clean energy market rally marks a modest boost for Ørsted, which has lost more than 70% of its market value since Trump returned to the White House in 2025 and resumed his salvoes against the industry as it struggled against fast-rising interest rates and supply chain pressures.

The White House has levelled multiple stop-orders against Ørsted’s Revolution Wind project since the re-election of Trump, a vocal supporter of the fossil fuel industry, who has repeatedly opposed the development of “ugly, costly and inefficient” windfarms in the US and abroad.

The impact has been chilling for the burgeoning US renewables sector too. The US is home to renewable energy projects with a combined capacity of 388 gigawatts, or enough to power more than 83m American homes. The sector also directly employs more than 400,000 people across the country.

This fleet of wind, solar, hydro and geothermal power projects has made up about 30% of the electricity generated across the US this year – well below the 50% share across the EU and China’s 40%.

While there is no binding US-wide clean energy target, there are 24 states, plus the District of Columbia, with plans to achieve 100% clean electricity or net zero carbon emissions between 2035 and 2050.

But there has been growing disquiet over whether the forecast surge in electricity-hungry AI datacentres poses a threat to green targets by increasing the US reliance on gas power plants – and energy costs.

“This was unquestioningly an energy election,” said Brenda Shaffer, a senior fellow at the Atlantic Council’s Global Energy Center. Rising concerns over energy costs and the looming impact of datacentres on energy supplies had played a key role in Republican defeat, she said.

The Democrats’ decisive control of the US House of Representatives and its majority in the Senate may reduce the risk of further political interference and bring fresh confidence to the US renewable energy industry, according to market analysts.

The Democratic house would be able to block further repeals of solar and wind tax credits, said Claudio Galimberti, the chief economist at the consultancy Rystad Energy. Battery storage credits would also now have a stronger defender in budget negotiations, and the administration’s roughly $4bn in offshore wind lease buybacks would face greater scrutiny, he added.

While it was too early to call this a turning point for US offshore wind, said Tancrede Fulop, a senior equity analyst at Morningstar in the Netherlands, the election outcome might lower the risk of further regulatory disruption and provide a more stable backdrop for projects under development.

“For companies that have spent the past few years dealing with regulatory delays and shifting political priorities, a more supportive backdrop should provide some much-needed confidence around projects already under development,” he said.

This in turn may ease investor jitters around regulatory uncertainty and support confidence in future project returns, according to analysts at Barclays, which could make new US renewable energy projects cheaper to finance.

The future was even brighter for developers hoping to build new onshore renewable energy projects, including batteries, which are typically decided at state level, said Shaffer.

A string of Republican states have turned blue – including Texas, Maine, Kansas, Ohio, Iowa and North and South Carolina – potentially ushering in greater support for clean energy investments.

The “blue wave” had made it clear that “affordable, reliable power is a priority”, according to Jason Grumet, the chief executive of the American Clean Power Association (ACP). “And our industry is ready to deliver it.”
