U.S. Senators are again taking a closer look at Bitcoin mining. Senator Ed Markey (D-Massachusetts) chaired a session of the Committee on Environment and Public Works yesterday, focusing on the energy usage of mining. The mining industry, Markey said, “deserves the spotlight.” Markey is the sponsor of a bill pushing for more transparency from miners regarding their environmental impact.

“It has grown explosively in the United States over the past two years. It is extremely energy-intensive. And we’ve seen it harm the general public while enabling the creation of heavily-concentrated wealth in our country,” he said. He said that the full extent of miners’ impact was not known, which was why his bill would require companies to disclose more information about their operations to the environmental regulator.（Decrypt）
