Tesla CEO Elon Musk issued a tweet on Friday declaring that oil and gas output should be ramped up, even though he acknowledged that such a move would have a negative impact on Tesla, which sells electric vehicles.

“Hate to say it, but we need to increase oil & gas output immediately. Extraordinary times demand extraordinary measures,” Musk tweeted. “Obviously, this would negatively affect Tesla, but sustainable energy solutions simply cannot react instantaneously to make up for Russian oil & gas exports.”

He also tweeted the message, “Hold Strong Ukraine,” along with Ukrainian flag emojis. He followed that up by tweeting, “And also my sympathies to the great people of Russia, who do not want this.”
