U.S. Energy Secretary Steven Chu said on Friday that the United States needs to come up with a better system for storing or disposing of radioactive nuclear waste than a planned repository near Las Vegas.

“The president has made it very clear that we are going to go beyond Yucca mountain. You should go beyond Yucca mountain,” Chu said. “But instead of wringing my hands, let’s go forward and do something better.”

The Obama administration, in January, announced it was stopping the license application for a long-planned multi-billion dollar nuclear waste storage site at Yucca Mountain near Las Vegas, which is opposed by environmental groups. (more…)

Bloom Energy has unveiled its long-awaited and much-hyped fuel cell technology, which it says can convert natural gas into electricity through an electrochemical process that reduces greenhouse gas emissions by 50 percent and at a price competitive with far-dirtier coal-fired electricity.

With California Gov. Arnold Schwarzenegger in attendance, Bloom co-founder and chief executive K.R. Sridhar unveiled his Bloom Energy Server at the Silicon Valley headquarters of one of its first customers, eBay.

Taking up no more room than a parking space and looking like a large refrigerator, the servers (at left) — which cost roughly $750,000 — convert natural gas or another fuel into electricity by creating an electrochemical process on a series of small, stacked disks.

The 26th annual Cleantech Forum begins today in San Francisco. With the theme of “Taking Cleantech to Scale,” this year’s conference focuses on how companies can take advantage of the growing funds available from government and the private sector.

At Friday’s “Information and Clean Technology” session, Microsoft’s Troy Batterberry will discuss the company’s Hohm software, one of the early strong entries into desktop home energy management. Below, Batterberry’s colleague Meredith Budwin previews his presentation.

Matter Network: Explain what Hohm does for a homeowner.

Budwin: Microsoft Hohm was designed to help consumers make smarter decisions about saving energy and money. Hohm uses information provided by consumers to provide personalized behavioral and home improvement recommendations, specific to their home’s situation. (more…)

Wind power capacity grew by 31 percent globally in 2009, with the steepest rise occurring in China, according to a new study.

About 37.5 gigawatts of capacity were added last year, boosting the total capacity worldwide to 157.9 gigawatts, says the Global Wind Energy Council, an industry trade group based in Belgium.

The growth occurred despite the weak global economy as major nations made renewable energy a priority of their economic stimulus plans, said Steve Sawyer, the council’s secretary general.

With this post, CleanTechies is diverging from our usual content with this light-hearted Valentine’s Day tribute to clean energy from the Vote Solar Initiative, which is working to make solar power mainstream.

People love solar. There are plenty of reasons why that’s the case. Solar creates local jobs. It produces reliable electricity when we need it most. It improves energy independence by tapping a homegrown resource. It offers real hope in the fight against global climate change. And ultimately the idea that we could be harnessing electricity from that big, yellow sun of ours just makes people feel good.

Always up for a good sun pun, Vote Solar thought we’d hammer that point home with a tongue-in-cheek Valentine Video campaign. (more…)

The National Resources Defense Council Action Fund released a video clip last week designed to echo Obama’s call to move America towards a “clean energy economy” in his State of the Union address.

The video is part of the “This is Your Moment” campaign, which features a host of celebrities, such as Jason Bateman, Leonardo DiCaprio, Felicity Huffman, Justin Long, Edward Norton, and Forest Whitaker, urging Congress to pass the first-ever climate and clean energy bill, currently pending in the Senate.

The U.S. wind power industry continued to grow in 2009 despite a global recession, adding 9,900 megawatts — a capacity increase of about 39 percent — according to a new report.

That growth, which was boosted by a federal stimulus package that extended the tax credit for wind energy production and offered other incentives, represents the largest single-year jump on record for the industry, according to the annual report released by the American Wind Energy Association.

The added capacity was 18 percent greater than the growth in 2008. But that momentum could slow in 2010, the report said, since the sluggish economy has slowed orders for new turbines and will likely mean fewer installations this year.

With the added capacity, wind energy contributes nearly 2 percent of the nation’s electricity. The U.S. continues to lag behind Europe, however, which gets about 5 percent of its electricity from wind energy.

TAIPEI (Reuters) – Outdone by an tower extending over 800 meters in Dubai, the world’s former tallest building, Taipei 101, wants to become the highest green structure by completing a checklist of clean energy standards, a spokesman said on Monday.

Taipei 101 will spend T$60 million ($1.9 million) over the next year to meet 100 criteria for an environmental certificate that it would hold over Dubai, spokesman Michael Liu said.

The office-commercial tower that reigned for five years as the world’s highest building at 509 meters (1,670 feet) expects the U.S-based Leadership in Energy and Environmental Design to give it the certificate in 2011.

Amidst the global recession and discussions surrounding the capital intense nature of most clean tech companies and the question of viable exit strategies for the venture capitalists that invest in them, the IPO market will continue to be dry.

The broader IPO market has been relatively dry since the start of 2008, with relatively few listings compared to previous years (~25/year vs averages from 1980s to 2005 of around 400/year).

While Sarbanes-Oxley is partially to blame for the dearth of US based IPO’s the fact is the public’s faith in and funds for the markets have been squeezed, and I feel that it might be more than wishful thinking that 2010 will be a robust year for Wall Street based IPOs of any sort, particularly clean tech investments.
