 Can you imagine if Raid had stood up in 96 and said what we're going to do is we're going to have a 10% reduction on energy footprint? The engineers that have gone, yeah, I'm sure we can do that. But what we said was we're going to have zero and to get to zero we're going to reduce our energy requirement and then we're going to move to renewables and that's exactly what we did. A 60% reduction in our global energy requirement is huge. Think about the financial benefit of doing that if all organisations really took a hard look at energy and started to reduce their usage of energy.
