What should be the real cost of using oil/coal for our modern lifestyles?
Well Goof, no doubt there could be hundreds of variables in comparing the pros and cons of these choices. Maybe also your perspective on how it should be thought about and/or suggestions you have for society could be the best. Part of the issue you aren’t mentioning is the actual production today as to why the costs are as they are. To move the prices closer to what you are saying would need government fiat declaring perhaps higher taxes on coal/oil and/or major subsidies of solar production. I certain you are aware that in many instances and localities especially areas with abundant sunshine are already seeing benefits of solar energy production today on an even cost comparison. Regional differences in the world are generally a fairly important factor on this type of comparison you are talking about.
