Green Options

While cleantech investment appears to be on the rebound, it’s clear the recession isn’t over yet. Mark Jensen, managing partner for the venture capital services group at Deloitte & Touche, said Wednesday that about half of the largest venture-capital firms expect to reduce their overall investments in the next few years in response to the recession.

But venture-capital firms expect cleantech to fare better than most other categories. According to the Deloitte survey, a whopping 95 percent said they plan to either increase or maintain their level of cleantech investment, with 63 percent anticipating more investment and 32 percent expecting to invest the same amount as they do now.

Solar venture investments hit a three-year low in the second quarter, the Cleantech Group said Wednesday. According to Brian Fan, senior director of research for the group, solar startups in North America, Europe, China and India raised a total of only $113.8 million for the quarter, which is down 7 percent from $365.7 million in the first quarter and down 86 percent from $834.7 million in the year-ago quarter.

Most odd stories relating to the environment tend to revolve around researchers and scientists and their slightly off the wall discoveries. But not so today. Today, in news of the weird – or at least slightly surreal – I bring you Daimler, the German automaker, who announced last week their very first hybrid car, the Mercedes Benz S Class. It’s a limousine.

Two weeks ago, we took a look at news from the Congo involving “conflict minerals”: armed groups have exploited the mining of materials such as tin, tungsten, gold, and tantalum, and the people who live near these resources, to fund their fighting. Since then, I’ve had a chance to communicate with David Sullivan, a research associate with the Enough Project, about the issues surrounding the situation in the Congo. David addresses the multiple atrocities — human and environmental — surrounding the trade of these materials, and the actions you can take to ensure electronics manufacturers are aware of these issues.

sustainablog: Oftentimes, situations like these arise from limited economic opportunities. What other means of making a living are available (or could become available) to people in the Eastern Congo? Are there options for these people that couldn’t be as readily exploited by armed groups in the area?

David Sullivan: Impoverished Congolese miners and their families are often entirely dependent on their meager income from mining, and they currently have few viable economic alternatives to lift them out of this indentured servitude. What could be the most promising alternative to mining is agriculture, but the threat of violence often forces Congolese farmers to abandon their fields to flee for safety.

Efforts to end the trade in conflict minerals absolutely must be accompanied by international support for livelihoods and economic opportunities in eastern Congo. Rebuilding roads is a key opportunity, so that other sectors can benefit from trade. Infrastructure projects with guaranteed labor at decent wages can help lure miners out of conflict mines and create opportunities for demobilized combatants. Larger firms can raise miners’ living standards if independently verifiable mechanisms are put in place to ensure that the corporations are not contributing to armed groups, and health, safety, and labor standards are observed at mining sites. International investment should be stepped up in agricultural development initiatives in eastern Congo, which mining has displaced in recent years.  Good models for agricultural investments in mining areas exist in Sierra Leone. Other livelihood initiatives, such as small business development projects, should also be promoted. All projects should be designed in close partnership with miners themselves, and should also be followed up with education initiatives for miners.

As stimulus funding leads some industry insiders to think of Washington as “the new Wall Street” for green energy, some investment experts say they’re concerned about the government’s new role. “I worry about the government as a dealmaker in this space,” said Tom Bratkovitch, director of LP Capital Advisors, a consulting firm for private-equity investors, at a Thomson Reuters conference in Palo Alto, Calif., this week. “I just don’t know if the government is the best one to make decisions in this space.”

After all, the federal government has supported some technologies that have not panned out, while missing some that have ultimately been successful. The government also has a reputation for moving slowly – though the Department of Energy certainly is trying hard to get stimulus money out as quickly as possible – and the applications for the grants and loan guarantees can be extremely time-consuming.

One solution to the world’s water pollution problems could be something you can’t taste, touch, see, smell, or hear.  Especially hear.  Ultrasound, the range of frequencies beyond the limits of human hearing, is starting to emerge as an effective water treatment that is more sustainable than chemical dosing.  Researchers are discovering that ultrasound performs well on algae, and that’s only the beginning.  Ultrasound can remove a variety of pollutants in water, including those that affect the taste of America’s favorite fish, the catfish.

Washington is starting to wake up to something that’s been obvious to marine scientists for years. The winds blowing off U.S. waters could be a key to a national clean energy and green jobs revolution.

On Tuesday, the federal government awarded five leases to three companies that want to develop wind turbines off the New Jersey and Delaware coasts for the production of renewable energy.

They’re the first such leases the Department of Interior has ever issued for the Outer Continental Shelf. If this official statement is any indication, they won’t be the last:

“We made the development of offshore wind energy a top priority for Interior. The technology is proven, effective and available and can create new jobs for Americans while reducing our expensive and dangerous dependence on foreign oil.”

The declaration comes as the U.S. Congress is in the midst of a debate over a proposal that would create a costly long-distance “transmission highway” to carry land-based wind energy (among other clean and dirty sources) from the Great Plains to the power-hungry cities of the American East.

Sometimes it is hard to contemplate what a good news story our industry – solar sales and installation – and the broader clean energy economy really represents. I was reminded on Monday at the graduation ceremony for the Oakland Green Collar Jobs Corps.

At one point, it seems as though virtually everyone has sat in front of washing machine and watched the soaked clothes tumble through the suds. That tradition may be a thing of the past if a new “virtually waterless” laundry machine finds its way to the mainstream.

Although only in prototype stage, this new machine may be able to save up to 90% of water compared to a conventional machine and will also cut carbon emissions. Created by Xeros, this machine replaces the old school idea of cleaning clothes. The technology goes with full on chemistry advances by replacing the majority of the water with reusable nylon polymer beads, the machine can clean clothes in less time than traditional machines, and we see these waterless wonders then you can thank Professor Stephen Burkinshaw, from the University of Leeds who made the discovery that certain types of polymer beads could be used for cleaning.

Cleantech startups have stopped seeing GE as an adversary and have started realizing the company can help them make a difference, Kevin Skillern, a managing director at GE Energy Financial Services, said in a keynote speech at a Thomson Reuters conference called “Financing the Cleantech Vision” in Palo Alto on Wednesday.

In spite of the recession, Skillern assured the audience that the long-term business opportunity for cleantech is still there, though it will require “a strong stomach and a lot of patience” to cash in on it. He also called climate change “one of, if not the biggest, societal challenges of our time” and said technology was an essential part of the solution.

Move over, silicon: graphene is ready for its closeup.  Discovered just a few years ago, graphene is a sheet of graphite the thickness of just one atom.  It can be processed like silicon to make electronic devices, which makes it easier to manipulate than the current “it” material, carbon nanotubes.  Without the breakdown problems that beset silicon at the nanoscale, graphene is bringing the dream of a molecule-sized computer closer to reality.
