 Record rainfall, faulty gates and inherent design issues contributed to the July 2010 breach of Iowa's Delhi Dam, investigators found. The overtopping caused the earthen embankment to erode and eventually emptied Lake Delhi, causing millions in property damage. |

 Renewable energy in the United States is at a crossroads. With several federal tax grants set to expire by the end of 2012, utilities are trying to decide if the falling prices of solar and wind technology makes renewable energy competitive enough to invest in despite vanishing federal aid. |

 Due to growing urbanization and resulting environmental threats, China has invested nearly US$50 billion annually into its renewable energy sector since 2009. China's five-year investment in environmental protection is on track to reach 3.1 trillion yuan (US$454 billion). By 2015, its environmental protection industry is expected to top 2 trillion yuan (US$317 billion). |

 In recent years, run-of-the-river hydropower projects have emerged as a viable, low-impact alternative to existing large-scale projects. Run-of-the-river facilities use conventional hydropower technology to produce electricity by diverting river flow through turbines that spin generators - before returning water back to the river downstream. |

 When Frank Zammataro thinks about water pressure, he sees an opportunity to create electricity.
Zammataro, 53, is President and Co-Founder of Rentricity—a New York City energy company that has discovered a new way to tap into the excess pressure in water-treatment plants, reservoirs, and factories to help power our water infrastructure, which consumes four percent of America's electricity. |

 Securitizing renewable energy networks from cyber-attacks is not complicated by their oft-cited operational headache of intermittency, but rather by their separation from a utility's control system, said smart grid executives at the Gridwise Global Forum in Washington, DC in early November. Though renewable intermittency adds to the challenge of stabilizing a grid, the forum revealed new evidence of real-world smart grid load shifting that continues to chip away at the tired argument that renewable energy cannot successfully integrate into a legacy grid. |

 Chile is built for renewable energy. The seemingly unending coastline that runs the length of its boundary is prime real estate for wind development, and eventually the offshore wind projects, that could power the cities found along its spine. The nation's solar resources, especially in the northern regions, are among the best in the world. And its place along the ring of fire means its geothermal potential is vast, yet untapped. |

 If there was one key takeaway from the most recent RenewableEnergyWorld.com and Solar Power-gen webcast it was that the year ahead will be difficult for large-scale solar power development due to poor access to capital, an uncertain policy landscape, the pending trade case against China and module prices that are too low to support a healthy indust |

 Building transmission to accommodate utility-scale renewable energy generation in the U.S. is seen as essential by much of the renewable energy industry. But can it be justified? Doing so will necessarily involve constructing some of the longest stretches of wire ever undertaken in this country. Much of the best wind and solar resource is located quite distant from the load. Ultimately, thousands of miles of huge power lines will have to be built. It is not illogical to ask whether investment in such massive infrastructure "costs too much and provides too little." It is also not illogical to answer "no," not if the value proposition is laid out appropriately and a well crafted policy and regulatory approach can be established that effectively addresses the issues. |
