Green: About Money AND the Environment

It's interesting to see companies position efforts to cut expenses as environmentally friendly actions. Look at the beverage industry: wine bottles are thick and heavy, and made of glass. Some winemakers are moving toward lighter bottles, and others are switching to plastic.

What's really going on here? For some reason I doubt the environment factor plays a significant role in the decision-making process. 

In reality, plastic is cheaper, lighter, and more durable. This should lower the cost of goods sold (shipping, materials, etc.), and increase profits. Positioning it as a green move may bring in some environmentally friendly customers and drive revenues. It's a business decision with positive impacts on the planet. 

Maybe that's the key to green energy? Make it about the money
