How much would electricity cost in the United States if the retail price reflected the health impacts of burning fossil fuels?
FORBES: How Much Do Health Impacts From Fossil Fuel Electricity Cost The U.S. Economy?
Estimated first-year electricity cost with solar: This is roughly how much you would pay for local electricity after accounting for the value of electricity your system produces.
Estimated first-year electricity cost before solar: These assumptions included base rates, fees and taxes, and factor in typical regional power loads, according to Heather Van Schoiack, spokeswoman at Clean Power Research.
Among the customizable settings are fields to enter the owner's cost of electricity, cost of a gallon of gas and the miles per gallon of their alternative vehicle.

Clearly, though, the Bloom Box is still not a zero emissions tech and would only cut emissions by roughly 50% relative to the national average, unless it runs on landfill gas or biogas or hydrogen from electrolysis fueled by zero-carbon electricity (which would be much more expensive as you have to add cost of electrolysis unit, higher cost electricity, and about 30% conversion losses in electrolysis).

Seventy-five percent is a magic number in my mind -- 70-75 percent -- because that means the cost of electricity of photovoltaics is less than the cost of new fossil energy.
Many provinces are suffering power shortages because producers have little incentive to generate electricity given the high cost of coal and the low state-mandated electricity price.
The objective: store massive quantities of electricity at low cost for grid applications safely and efficiently.
"If they can get enough renewable, low-cost electricity, that's a big determinant, " he told BBC News.
Many of those contracts promise to supply electricity below the cost of energy produced by natural-gas fired power plants.

Specifically, electricity from natural gas power plants comes at less than half the cost of electricity from coal generators.

Higgins intends to attach to the line 200 megawatts (peak output) of windmills, ostensibly generating electricity at a cost of 7 cents a kilowatt-hour, and has contracted to buy all the output of a 65-megawatt solar plant that would be an eco-loss-leader costing 25 cents per kwh.
According to the GE-Arista partnership, GE, the largest maker of power-generation equipment, will join with Arista Power to sell systems that store electricity for commercial customers and release it when demand is at its highest, which would help reduce the cost of electricity.

The solar mission in its first phase focused on areas already connected to the grid and had a pricing system that bundled four units of thermal electricity with one unit of solar-based power, which reduced the average per-unit cost of solar electricity.
It would also drive up the cost of electricity, and make wind power more lucrative.
Ministers say this will secure clean and reliable electricity at a minimum cost to consumers.

In the long term, it will increase the cost of electricity to consumers.
This reduction in size and weight would lower overall wind development costs, resulting in a lower overall delivered cost of electricity.
Not surprisingly, by far the biggest factor in the cost of electricity generated by solar is the installation costs for a system.
Paolini explains that if you have a 10% rise in the price of oil, that will translate into a 10% higher cost for electricity.
Overall, the cost of electricity, which declined (in real dollar terms) for the last two decades of the 20th century, has been relentlessly tracking up since 2001.
The cost of electricity is bumped up by 28 different taxes which together account for almost half the average bill, according to Acende Brasil, an energy-research institute.
He put aside the costs of buying the cars, and ignored the effect of taxes, to focus just on what it would cost in electricity or gasoline to travel a mile.
If hardware lasts two years and if, let's say, electricity and other overhead cost as much as the hardware, Amazon would have a gross margin of 45%, better than what it gets on books.
Thanks to advances in software, a new generation of startups like Columbia Power are cheaply and quickly testing hundreds of new designs in virtual oceans while veterans of the industry are perfecting their technology to wring more energy from waves and lower the cost of electricity.
So, a solar power plant equipped with a QBotix robot will generate power at a levelized cost of electricity (LCOE) that is 8 to 15 percent lower than a power plant with single-axis tracker and 15 to 20 percent lower than a power plan with panels in fixed positions.
The website lists rebates and other subsidies that help to defray installation costs and provides a calculator for figuring out the cost of electricity, the payback period and the return on the investment from installing small wind turbines, which refer to those that are under 100-kilowatt in size and engineered for residential and business properties, including farms and government agencies.

"Moreover, in places that do generate electricity from renewable sources, it would be more cost-effective to use that electricity to power electric or plug-in hybrid cars than high-speed rail, " O'Toole said.
