• The Solyndra guarantee

    Solyndra did what it said it would do with taxpayer money. But should it have been asked to do more?

    A lot of Solyndra coverage has focused on the Department of Energy loan restructuring and resulting repayment priority, and we've certainly done our share. But I'm also interested in the original $535 million loan itself, which was designed to finance the construction of a large new manufacturing facility (which was, in MORE

  • Bloom Energy worth nearly $3 billion

    Bloom Energy powers up with big new funding round.

    Fuel cell maker Bloom Energy has not received any Department of Energy grants, but it sure does keep raking in the private financing. Fortune has learned that the Silicon Valley-based company recently raised $150 million in new venture capital at a $2.7 billion pre-money valuation.

    Impressive for a company that receives eye rolls from virtually every cleantech VC who hasn't yet invested in it. MORE

  • How to build a cleantech success

    To understand the future of cleantech, we must analyze the past.

    By Matthew Nordan, contributor

    I entered the venture capital business two years ago, focusing on cleantech start-ups. It's kind of like picking a future NBA draft by watching eighth graders play basketball: There are many years worth of development to go, and the subjects will look a lot different once they're all grown up. The key is excellent pattern recognition – MORE

  • What went wrong at Solyndra

    A solar energy CEO discusses the pending bankruptcy of Solyndra, which had raised more than $1.5 billion from private investors and the U.S. government. 

    By Barry Cinnamon, contributor

    The epitaph for Solyndra is significant because of what was not a factor in their demise.  It was certainly not for a lack of trying. But more importantly, it was not because of Chinese competition or a lack of U.S. government support.

  • Solyndra fades away

    One of America's most expensive cleantech bets just bit the dust.

    Solar panel maker Solyndra today said that it will file for Chapter 11 bankruptcy protection, after failing to successfully compete against lower-cost Chinese manufacturers. It is one of largest failures ever suffered by venture capitalists, and a major black eye for a U.S. Department of Energy that loaned the company more than $500 million.

    The company has not yet filed its MORE

  • GM helps electrify city buses

    Could we soon have city buses without their accompanying pollution?

    General Motors (GM) has gotten lots of buzz for its Chevy Volt, but the automaker's most important electric vehicle contribution may not have anything to do with autos at all.

    GM today announced a partnership with Proterra Inc., a Golden, Colo.-based maker of "zero-emission commercial transit solutions." More specifically, Proterra makes fast-charge electric buses and automated bus charging station (10 minute recharges). MORE

  • End Big Oil's tax breaks now

    It's time to truly level the playing field and give all forms of energy a chance to compete.

    To hear some tell it, we have lost our collective appreciation for free markets. So writes CNBC anchor Joe Kernan in his new book about "defending our kids from the liberal assault on capitalism." Or former BB&T CEO John Allison, who offers $2 million grants to colleges that create "courses in capitalism." And MORE

  • Tesla Motors: Not so different after all

    Tesla Motors' stock has become a handy object lesson in how cleantech IPOs cannot escape their fate.

    By Heidi N. Moore, contributor

    Tesla (TSLA) enjoyed an encouraging first day of trading when it went public last week. The stock turned in a whopping 40% increase to its $17 offering price, to close the day at $28.39. At one point, it even traded at a 70% premium to its offering price. For a MORE

  • Tesla's IPO: False promises for clean tech

    Don't get swept up in the hype of the Tesla IPO. Clean tech is not yet ready for prime time.

    by Heidi N. Moore, contributor

    It's a common convention for horror movies to have at least one character who, cornered by the monster/attacker/murderer/villain, yells to his compatriots, "Go on without me! Save yourselves!" The same phrase should also be common among clean technology companies listing for an initial public offering.
