〔脱原発の切り札が生まれた〕★ 「キロワット/時」あたりのコスト、なんと、たったの２セント！ 脅威のスーパー電池を開発 それも家庭、工場、発電所で使用可能 / 米「テスラ」社が発表 名づけて「テスラ・バッテリー」 / アーニー・グンダーセンさんが公表に先駆け、「原子力の棺に最後の釘を打ちこむもの」と、大学での討論集会で明らかに！

　★　太陽光のコストは現在「キロワット/時」６セント、風力は４～５セント。それぞれ、４セント、２．５セントまで、下がりそうな情勢だが、この「２セント」は、それより安い。

　現在稼働中の米国の原発のコストに近く、次世代原発のコストの半分だそうだ。

　・　It would be almost three hours until Tesla’s big announcement, but inside a Northwestern University classroom near Chicago Thursday night, the famed nuclear critic Arnie Gundersen had the inside scoop:

　Tesla Motors CEO Elon Musk was about to announce an industrial-scale battery, Gundersen said, that would cost about 2¢ per kilowatt hour to use, putting the final nail in the coffin of nuclear power.

　・　Then Gundersen told the audience of about 80 students and visitors that it was a momentous day in history—because of something that was about to happen in California. He evoked Elon Musk, the founder of PayPal , chairman of SpaceX and SolarCity, and the product architect for Tesla Motors:

　“At about ten ‘o’clock tonight he’s going to hold a press conference and he’s going to announce that he’s going to build industrial scale storage batteries. While the announcement is still two hours away, it appears that they’ll be able to produce these large batteries for about 2¢ per kilowatt hour. That’s an enormous breakthrough,” Gundersen said.

　“So the nuclear argument that they’re the only 24-7 source is off the table now because  Elon Musk has convinced me that industrial scale storage is in fact possible, and it’s here.”

　And a few hours later Musk announced the launch of Tesla Energy, ”a suite of batteries for homes, businesses, and utilities fostering a clean energy ecosystem and helping wean the world off fossil fuels.” Many had anticipated the batteries—but not the price.

　・　Solar power costs six to seven cents, he said, and wind costs four or five cents.  Add 2¢ for the cost of a utility-scale Tesla battery, and renewables with reliable storage are still at half the price of new nuclear power.

　・　The real cost of various sources of energy is a topic of debate. Last year the U.S. Dept of Energy said the cost of wind power had reached a new low of 2.5 cents per kilowatt hour (pdf). The cost of solar is typically pegged much higher, but the UN Energy Information Agency estimates solar is on a path to a cost of about 4 cents per kilowatt hour in coming decades.
