\r\n\r\n<\/a>\r\nPower generation for both traditional electricity uses and transportation\r\nis changing.\r\n

\r\nMichael Liedtke and Jonathan Fahey wrote for AP and Inc. 1 May 2015,\r\n\r\nElon Musk Unveils Tesla’s Ambitious New Home Battery System:\r\n“Our goal here is to fundamentally change the way the world uses energy,” Musk told reporters gathered in Hawthorne, California.<\/a>\r\n

\r\n

\r\nThe batteries are likely to become more useful if, as expected, more\r\nutilities and regulators allow\r\n\r\n power prices to change throughout the\r\nday based on market conditions. That way, the software that controls\r\nthe solar and battery system will allow customers to use their\r\nhome-generated power—and not expensive grid power—when\r\ngrid prices spike.\r\n<\/p>\r\n

\r\nMany commercial customers already buy power this way, and Tesla also\r\nannounced battery systems designed for them, along with bigger\r\nbattery packs that utilities can use to manage their grids. Analysts\r\nsay these utility and commercial markets will probably be more\r\npromising for Tesla during the next few years than residential\r\ncustomers.\r\n<\/p>\r\n

\r\nSeveral businesses, including Amazon.com and Target, plan to use\r\nTesla’s battery storage system on a limited basis. Southern\r\nCalifornia Edison is already using Tesla batteries to store energy.\r\n<\/p>\r\n<\/blockquote>\r\n

\r\nAnd what about Southern Company, whose CEO, Tom Fanning, drives a Tesla?\r\nMaybe we’ll find out at\r\nthe SO stockholder meeting<\/a> 27 May 2015.\r\n

\r\nAccording to Tesla’s\r\n\r\nPowerwall web page<\/a>,\r\n
\r\n10 kWh $3,500\r\n
\r\n  7 kWh $3,000\r\n
“Ten year warranty with an optional ten year extension.”\r\n
And multiple batteries can be installed at same location.\r\n

\r\n

\r\nPowerwall is a home battery that charges using electricity generated\r\nfrom solar panels, or when utility rates are low, and powers your\r\nhome in the evening. It also fortifies your home against power\r\noutages by providing a backup electricity supply. Automated, compact\r\nand simple to install, Powerwall offers independence from the\r\nutility grid and the security of an emergency backup.\r\n<\/p>\r\n<\/blockquote>\r\n

\r\nNotice the wording here: “independence from the utility grid”,\r\nwhich is very different from how so many stories are spinning this;\r\nit’s not “off the grid”.\r\nI already have batteries for my first 3KW solar panels,\r\nand many a time they’ve kept lights, refrigerator, Internet connection,\r\nand computers humming along when the grid has been out.\r\nBut I still like to sell<\/em> power to the grid.\r\nThat not only reduces my power bill, it helps reduce\r\nfurther fossil fuel expansion, and\r\nif enough people do it, that will take more coal plants offline.\r\nAs SolarCity CTO Peter Rive previously remarked<\/a>,\r\n“the grid is a network, and where there are networks,\r\nthere are network effects.”\r\nAdding batteries increases the network effects of reducing total\r\nneeded fossil fuel power production,\r\nand making the whole grid more resilient by distributing energy production.\r\n

\r\nThe most significant thing about Tesla’s home battery announcement is that\r\n\r\nit opens a market for all the other contenders<\/a>:\r\ncapacitors<\/a>,\r\nand\r\ncompressed air underground storage<\/a>,\r\nand\r\nRobert Green’s pumping water uphill<\/a>,\r\nand\r\nHarvard’s organic flow battery<\/a>,\r\nand\r\n\r\nStanford’s aluminum battery<\/a>,\r\nand probably still others not announced yet.\r\n

\r\nIt only took a decade or two for much of the shift from horse-drawn\r\ncarriages to internal-combustion automobiles.\r\nThe shift from fossil fuels to sun, wind, and water-generated power\r\ncan be even faster, and it’s already started.\r\n
