Danish renewables group European Energy has entered into several long-term power purchasing agreements (PPAs) with Microsoft to supply the U.S. tech firm with green electricity, the Copenhagen-based company said on Wednesday.

"The renewable energy will be produced by a portfolio of wind and solar assets in Sweden and Denmark," European Energy said in a statement.

It will under the agreements deliver more than 3.6 terawatt hours (TWh) over the contract period, supporting Microsoft's goal to meet all its energy demand with power from renewable sources by 2025 and be carbon negative by 2030, it said.
