North Carolina, two U.S. researchers claim that solar electrical energy even cheaper than the subsequent generation of nuclear power. According to researchers at Duke University within the state in a report released last month, the place the sharp decline within the price of solar energy has been lower than the cost of new nuclear power. The authors say their research pointed to a “historic position”, which vastly strengthened the facility of renewable energy investments, advocates the same time weakening the voice of large-scale international nuclear energy development.

Report, North Carolina commercial-scale solar electric power utility companies to provide electricity for the worth of 14 cents per kWh or less. At the same time, the 2 new nuclear power plants are being planned to advertise local energy firms (DukeEnergy and ProgressEnergy) nuclear power worth based on present estimated 14 to 18 cents per unit.

This “translocation” The main reason is that over the past decade the cost of solar PV methods have fallen significantly. The report cites knowledge from Lawrence Berkeley National Laboratory, said the cost of PV in 1998, 12 U.S. dollars per put in watt dropped to 8 in 2008 dollars, fell by an average of 10 years, 1 / 3. 2008 to 2009 declined extra rapidly that in 1998 12 years since the costs in half. At the identical time, nuclear energy prices are going up. Peak in the nuclear era has just began, the United States the cost of building a reactor is about 20 billion U.S. dollars, is now a ten billion U.S. dollars.

Of course, the Duke University examine to be affected by regional conditions, 14 cents / kWh data is web of internet of public subsidies, is the regulatory environment in North Carolina values, where the tax on solar energy and pay concessions reduce the users cost. But the authors consider that photo voltaic energy is expected to be the following ten years with out government subsidies take the case of value competition. Compared with different alternatives, photo voltaic energy, and their competitiveness. Report the information to be passed as a whole is not unique to North Carolina. Britain’s largest solar vitality company Solarcentury company’s founder predicted five years, “even cloudy Britain,” additionally allows the solar vitality and fossil fuels to generate electrical energy evenly divided. Google has introduced a breakthrough in efforts to make renewable energy cost less than coal. Development have been round taking the practical steps. As of the top of 2009, total installed capacity of solar power around the globe more than 22 million kilowatts, whereas in only one year of additional capability to seven hundred million kilowatts, half of whom are in Germany.

However, some experts will not be aware of renewable power has stood on a “squeezing out” the location of new nuclear power. Fuluojiate that the nuclear industry within the United States the biggest threat just isn’t renewable energy, however natural gas. “Shale gas has fully changed the United States market, causing a sharp decline in natural gas prices,” he said, “In the longer term years, how one can develop in this area, yes enduring, Huan Shi flash within the pan, Jiang Cheng Wei vital issues facing the nuclear Chanye because this is crucial competitors. ”

Because of its intermittent properties for solar cannot replace base load nuclear or coal energy to say, Duke University researchers to refute the “antique” that when the solar power into a wind, hydro, biomass and natural gas composition when the ability grid, which has develop into a “can management the problem.” However, world engineering consultancy Mott MacDonald of the Department of Energy director Simon Harrison, this point continues to be crucial. “You must put the role of two ways the entire electricity provide and demand stability to be considered, when photo voltaic energy in the sun can play a role, however nuclear power is 24 hours a day. As we consider using solar energy instead of nuclear vitality before, we must a number of preparatory work, such as energy storage, such as sensible grid and so on. ”

However, Harrison also admitted that for investors solar and different renewable power sources has some excellent advantages. “The hassle is that nuclear energy is so bumpy twists and turns within the investment process, whereas renewable energy could be very easy. As the investment is very small, even with out the revenue loss is also affordable. Perhaps you would think about investing in the future to build 500 MW renewable energy, its cost of capital is equal to a nuclear power plant. But even the preconceived thing, you can do it slowly and gradually, the financing turns into easier. and that renewable energy is just not dependent on the provision chain so strong . ”

Olkiluoto fiasco facing the construction of nuclear power once again stressed the enormous financial and sensible challenges. However, in July this year, the Finnish Parliament has adopted two new reactors planned.Byrne and his colleagues in North Carolina, energy policy makers can give a good lesson, but they do not intend to listen to play is one other matter.
