| Minnesota Power Announces Second Wind Energy Project | |
| Minnesota Power, an ALLETE company, plans to expand its use of wind-generated electricity through the long-term purchase of energy generated from a 48-megawatt (MW) wind facility. The proposed Oliver Wind II Energy Center would be constructed, owned and operated in central North Dakota by a wholly owned subsidiary of FPL Energy. |

| EERC Demonstrates Hydrogen Production at Ethanol Facilities | |
| The Energy & Environmental Research Center (EERC) at the University of North Dakota (UND) is leading a project to demonstrate the production of hydrogen at existing and future ethanol facilities. The hydrogen produced could be used onsite in fuel cells to provide additional power for the plant or as fuel for hydrogen vehicles. |

| The Solar Industry Continues to Gain Momentum | |
| There has been a lot of discussion recently about the "new" growth of solar power. But, in fact, solar has been around for decades. What is now "new" is the opportunity to dramatically expand solar by increasing access through economies of scale. A parallel can be drawn between solar today and the story of the automotive industry. |

| Exploding Robots May Scout Hazardous Asteroids | |
| An anonymous reader writes to mention NewScientist is reporting that a small force of robots designed to explode could help reveal an asteroid`s inner structure. This could in turn allow scientists a better understanding of how to divert a rogue asteroid on a collision course with Earth. From the article: "The main spacecraft would stay a few dozen kilometers away, perhaps nudging the probes towards the asteroid using springs. Once on the surface, the protective spherical shell of each probe would open to allow the probe to scan the surface nearby. To reduce complexity and costs, the probes lack solar panels and run on battery power, limiting their lifetime to a few days. But each probe could still cover a lot of ground in that time, as they could be fitted with small thrusters to let them hop across the surface. Eventually the probes could detonate onboard explosives, sacrificing themselves for science one by one. Probes that had not yet detonated would listen for any seismic waves sent rippling out from the explosion, and the main spacecraft could observe the craters left behind. That would tell scientists about the asteroid`s strength and internal structure."

| Napa Winery Grgich Hills Partners With SPG Solar on 170 kW Solar Energy System | |
| SPG Solar announced today the commissioning of Phase II of the 170 kilowatt commercial photovoltaic (solar energy) system for the Grgich Hills winery in Napa Valley, California. Together Phase I, completed in 2005, and Phase II of the Grgich Hills PV installation will produce 170.08 kilowatts DC of electricity during peak production hours. With the completion of Phase II, the PV system is expected to meet 100% of the winery`s actual energy needs. The system will pay for itself within five years. |

| MIT-Led Study Says Geothermal Energy Is Viable | |
| amigoro writes to tell us about a study for the US Department of Energy, led by MIT, indicating that geothermal energy could account for 10% of energy production in the US by 2050. The study concludes that geothermal is proven, could impose markedly lower environmental impacts than fossil-fuel and nuclear power plants, and is likely to be cost-competitive with the alternatives. This coverage in LiveScience points out how big a player geothermal already is in the US: "The United States is the world`s biggest producer of geothermal energy. Nafi Toksöz, a geophysicist at MIT, noted that the electricity produced annually by geothermal plants now in use in California, Hawaii, Utah, and Nevada is comparable to that produced by solar and wind power combined."
