A £13.5m centre has opened to teach green skills and boost jobs.
The Centre for Green Technology at Peterborough College aims to tackle a skills shortage and support sustainable economic growth.
Hundreds of thousands of green jobs are needed to support the government's growth mission, said Baroness Taylor, a Labour peer who was at the launch.
Oliver, 18, said he felt he was improving his job prospects by attending the college.
He said: "Everyone's finding it quite hard [to get jobs] but it is giving me a lot of confidence doing my plumbing here."
The Inspire Education Group's facility was designed to ensure learners, employers and the community could adapt to the demands of a low-carbon future.
Green jobs are projected to reach over 440,000 by 2030 and employer demand for green skills grew by 46% last year.
Baroness Taylor said she wanted young people in the region to get jobs that could help protect the environment.
"Colleges like this, whether it is in green technology or other fields, are magnificent at doing that [involving, encouraging and enthusing young people with jobs]," she said.
"[They] help support our young people to get into the jobs, apprenticeships and training places that they need to start them off in their future lives and give them the hope they need for the future."
The centre has industry-standard facilities and immersive technology, including a virtual reality wall.
Rachel Nicholls, chief executive officer at the Inspire Education Group, said the centre was a "key milestone".
She said it "reflected a commitment to creating campuses of the future, where learners gain the skills they need, employers find the talent they're looking for and communities benefit from inclusive, sustainable growth".
The Mayor of Cambridgeshire and Peterborough, Paul Bristow, said it was tough for people who did not have the right training for the new jobs on offer.
"Few people are aware that the Combined Authority has a big role on skills," he said.
"It's put nearly £3m into getting these impressive facilities open.
"I want our skills funding to mean two things: getting a job and getting a better job. Given its close links with employers, the Centre should be a real boost for Peterborough and the region."
