Trinick, who led the advice on the first-ever UK wind farm at Delabole in Cornwall, will join Eversheds' clean energy and sustainability group.
Michelle Thomas, head of clean energy and sustainability at Eversheds, said Trinick will assist in expanding the firm's capabilities on sustainability issues across various sectors.
Thomas said: "Marcus's appointment will add further depth to our team and only increase our ability to capitalise on the expected growth in the market, particularly offshore and onshore wind".
Trinick, the UK's leading wind farm expert, has acted on more than 220 proposed renewable projects in the UK and appeared as an advocate in more than 30 wind farm public inquiries.
The loss of Trinick will cause major ripples across Bond Pearce, which is focusing on the renewable energy sector as a lifeline to lift the firm out of its recent financial woes (The Lawyer, 8 October 2007).
Bond Pearce energy sector chief Luke Gabb said the firm has seen a 70 per cent increase in turnover in its energy practice and wishes Trinick, a founding member of Bond Pearce's group, well.
Gabb said: "Trinick has been part of developing what is now one of the largest UK private energy practices and leaves behind an excellent legacy for us to continue to build upon."
