Ideally the cost would include all externalities and thus allow people to judge the value and bare the full cost. But kWh, or grammes of glass, or carbon credits, or whatever you want. Normal glass is very recyclable and doesn't require a lot of energy or resource to recycle. "Long life" glass may well not be recycled at all.
