It can run a PC for 3 hours and a T.V for 3.

Answer:

It is easier to discus this in terms of CO2 produced, the energy can then be identified from easily obtained CO2/energy factors for the power sources in each area.

Australian data indicates about 0.6 oz of CO2 is generated per oz of glass wine bottle produced.W ine bottles typically weighs about 23 oz, so about 13.8 oz of CO2 is generated for each glass wine bottle manufactured. As an aside, the US Environmental Protection Agency (USEPA) reports that the manufacture of plastic drink bottles generates 1 oz of CO2 per oz of plastic bottle. However as plastic bottles weigh less than glass bottles each unit generates about 1.9 oz of CO2 . So manufacturing of a glass wine bottle produces 7.3 times more CO2 is generated than a plastic one. Recycling the bottle for re-use (not melting down and re-manufacture) saves all of the CO2 and thus all of the energy.
