This is a good point and one that seems to be lost on many people. I always find myself explaining to people that electric cars are not in and of themselves “green” and that, in fact, the case can be made that they are less environmentally friendly since most of American electricity comes from coal and the burning of coal is in many ways dirtier (FAR more particulate matter) than the burning of gasoline.
Hopefully though advancements in technology will soon drive alternative sources into the cost-effective category. My highest hopes are for wind–it has the potential to become our cheapest and easiest source of energy and we have the added benefit of being one of the most blessed countries on Earth when it comes to wind maps. Solar Thermal Tower technology is also exciting though it seems less feasible in the near future.[/quote]
Wind power is still mindbogglingly expensive and additionally to inconsistent to be a power base.[/quote]

There is a chart on the bottom right. The cost isn’t as bad as people think and it is constantly decreasing. The cost of harvesting wind for energy on a large scale has fallen by 500% since the 1980s and no there is no sign of this trend reversing–in fact widespread mass manufacturing of wind turbines is expected to illicit a plummet in the initial capital needed to establish a windfarm.[/quote]
You should look more closely at what went into that. The “levelised” cost includes taxes. In other words that chart is for potential investors who would get money from taxes in a wind farm and have money taken away by taxes on a coal plant. Looking on the total cost on everyone (the real cost of the energy that has to be payed by someone, in this instance the tax payer) wind power is not reasonable. This chart is omitting the cost to the tax payer.[/quote]
I understand that, but since those taxes are a reality, they shouldn’t necessarily be excluded.
If you were to figure in the real cost (it is incalculable) of fossil fuels including the cost of fixing the damage we have done down the road and the political/military cost of dependence on foreign oil, it could be absolutely astronomical.
Either way, I agree that alternative fuels are too costly at the moment. Their price tag is ever decreasing, however, and we should all hope that at some point soon they become cost-effective.[/quote]
No, the cost of taxes should not be omitted like they were in that graph. all that does is shift the burden of paying for the cost of the increase. If we were to subsidize coal plants it doesn’t make coal more economically beneficial, it just means that public money is paying private energy bills. The money is still being payed its just a different channel.
The only reason to look at it the way it was graphed is if you are looking to invest in something and make money, Not if you are discussing the cost and viability of an energy source.
