CIGS is a modified copper indium selenide CIS that replaces 15% of indium with gallium for efficiency improvements ( A. et al., 1996 ), and its main components are potentially toxic ( Kwak et al.,

The Case for a Longer-Term Oil and Gas Bull Market

Green Living vs Green Signaling A widespread issue I see with behaviors around energy, is that individuals and institutions are more interested in looking green or feeling green, than being green. In other words, we get a warm feeling when we think we did something green or we can make others think we did something green, regardless of whether it truly is green in the full lifecycle of its existence.
