Renewable energy

摘要

Like some other types of mining, change comes very slowly to the ag gregates industry. Pick up a 1950s-era photo of an aggregates plant from our extensive photo archive, and unless a vehicle is in the shot to give a clue to the date, the picture looks like it could have been taken yesterday. So the move to renewable energy sources for mines of all types around the world is a big change. We've reported on this change in the recent past, such as our article "Here comes the sun" from last October, detail ing the use of solar power at the Stony Point Rock Quarry in California.
