Solar electricity cheaper than fossil electricity in 3 to 5 years


Bloomberg reported this week that Solar power may be cheaper than electricity generated by fossil fuels and nuclear reactors within three to five years because of innovations, according to Mark M. Little, the global research director for General Electric (GE) in the US.
“If we can get solar at 15 cents a kilowatt-hour or lower, which I’m hopeful that we will do, you’re going to have a lot of people that are going to want to have solar at home,” 
GE announced in April that it had boosted the efficiency of thin-film solar panels to a record 12.8 percent. Improving efficiency, or the amount of sunlight converted to electricity, would help reduce the costs without relying on subsidies.
The thin-film panels will be manufactured at a plant that GE intends to open in 2013. 
Total installations are forecast to increase by as much as 50 percent in 2011, worth about $140 billion, as cheaper panels and thin film make developers less dependent on government subsidies, Bloomberg New Energy Finance forecast.
The cost of solar cells, the main component in standard panels, has fallen 21 percent so far this year, and the cost of solar power is now about the same as the rate utilities charge for conventional power in the sunniest parts of California, Italy and Turkey, the London-based research company said.
Most solar panels use silicon-based photovoltaic cells to transform sunlight into electricity. The thin-film versions, made of glass or other material coated with cadmium telluride or copper indium gallium selenide alloys, account for about 15 percent of the $28 billion in worldwide solar-panel sales.
First Solar Inc. (FSLR), based in Tempe, Arizona, is the world’s largest producer of thin-film panels, with $2.6 billion in yearly revenue.
GE this year plans to introduce the “Nucleus,” a device that will let consumers track their household electricity use with personal computers and smart phones. 
In my earlier blog articles I reported that Nissan Leaf drivers are already using solar pv to power their cars and houses in the UK and US. Next year the range per charge of EVs will increase to 150 miles, giving an effective daily range of 300 miles with fast charging.
The Electron Economy is getting ready for launch.
