Suppose coal produces electricity at a cost of 0.06 per kilowatt hour, while solar power costs 0.16 kilowatt hour. The tax on coal based electricity would have to be 0.10 kilowatt hour.

The coal tax for 2014 is then set at 0.01 kilowatt hour, which is just enough to pay the needed solar subsidy of 0.09 kilowatt hour. Solar producers fully cover their costs of 0.16 kilowatt hour, since they sell power to the consumers at 0.07 kilowatt hour and receive a subsidy of 0.09 kilowatt hour.

Up to a threshold of around 100 kwh per capita per day, energy consumption and human development indicators go hand in hand.

The price charged to consumers would rise gradually from 0.06 kilowatt hour to the full cost of 0.16 kilowatt hour, but over a phase in period of, say, 40 years (the lifespan of the newest of today s coal plants).

In that case, consumers would pay 0.16 kilowatt hour for either coal or solar.

In fact, one cow can produce enough manure in one day to generate 3 kilowatt hours of electricity only 2.4 kilowatt hours of electricity are needed to power a single 100 watt light bulb for one day.

Danes pay the highest electricity rates of any industrialized nation, on average about 0.38 per kilowatt hour, compared to .08 in the United States.

Assume that as of 2010, the entire electricity system is coal based, and that the electricity price paid by the consumers is 0.06 kilowatt hour.

The consumer price is raised 10 of the way from 0.06 to 0.16, thus reaching 0.07 kilowatt hour.

The consumer price finally reaches 0.16 kilowatt hour, enough to cover the full cost of solar power without a further subsidy.

Today s solar power plants might cost an extra 0.10 kilowatt hour compared to coal, but such plants will be much less costly in the future because of improved technology.

In our example, the government would pay a subsidy of 0.10 kilowatt hour to the solar power plant to make up the difference between the consumer price of 0.06 and the production cost of 0.16.

For many developing countries, the figure is well under 20 kwh China is still well below the global average, and even most emerging markets consume less than one third of the average in many advanced economies.

In its most recent analysis, the US Department of Energy estimated that, using 2010 technology and assuming a production volume of 500,000 units, production costs for an 80 kilowatt fuel cell would be about 57 per kilowatt.

Thin disk lasers have been shown to produce beams of up to one kilowatt.

Let us presume, finally, that by 2050, all electricity production has made the transition to low carbon energy sources. The consumer price finally reaches 0.16 kilowatt hour, enough to cover the full cost of solar power without a further subsidy.

Moreover, given that the plants are already paid for, waste facilities are already in place, and the high decommissioning cost will have to be paid regardless of timing, the actual operating costs are very low half or lower per kilowatt hour than the cost of the cheapest fossil fuels.

With expected technology improvements, the cost would drop to about 47 kW by 2015, within shouting range of the department s target of 30 kW, a benchmark figure that more or less corresponds to today s manufacturing cost for gasoline engines.

Before anyone can consume a kilowatt hour, a liter of water, or a bus ride, somebody has to get a copper wire, a pipe, and a road to their house. These fixed costs need to be recouped through long periods of use.
