Despite widespread hope of a peace deal, US-Iran talks appear to have stalled.

Iran suspended peace talks on Monday and threatened the full closure of Strait of Hormuz, a crucial trade route for oil that has been effectively closed, save for a few tankers, since the U.S.-Israel attacked the Middle Eastern country on February 28.

It has sent energy markets into a frenzy, with governments and investors subsequently following as they looked to firm up alternative sources of power.

As energy prices continue to soar, there are some companies who are set to win: those in clean energy. High oil and gas prices have improved the near-term economics for operational clean energy assets, according to a PitchBook note released May 26.

The conflict reinforces the long-term policy case for domestic clean energy—but simultaneously raises input costs and delays the rate cuts that new wind and large-scale solar projects depend on,” it says.
