I had young kids, and they kept challenging me," Sykes said. "I thought, you know what, I want to do something with a bit more purpose." He made the leap and became the head of technology innovation at the Carbon Trust, a UK organization that helps governments and businesses decarbonize. Later, in 2012, Sykes joined rsted, a Danish energy company. He said it "absolutely was" a personal decision to "move from black to green." Today, rsted is the world's biggest producer of offshore wind. It has wind farms in the US, Germany, and the UK, and it produces 90% of its energy from renewable resources. rsted didn't start as a renewable-energy company, though. Like Sykes, it made a transition from black to green — and in doing so, it demonstrated it's possible for big energy companies to pivot to clean energy. The energy sector accounts for more than two-thirds of global greenhouse-gas emissions, the International Energy Agency estimates. To limit the influence of climate change, those emissions need to rapidly decrease — which means that big energy companies need to change their operations https://africa.businessinsider.com/news/from-black-to-green-how-an-oil-and-gas-company-pivoted-to-embrace-wind-energy-and-is/1l5y8wr
