Want to put solar panels on the house? Start saving… solar power is a great investment, but it is an investment… often a hefty one. If you’d like to get started with something a little less ambitious (but more affordable), you’ll find a number of good sources out there for a whole range of solar [...]
When President Obama signed the American Recovery Act, he alloted 20% of the funds to be used for developing a green infrastructure, water and energy efficiency improvements and other environmentally innovative projects. And Delaware’s aging water infrastructure is smiling because of it.
In order to cut harmful emissions from maritime vessels, the Environmental Protection Agency (EPA) announced the next steps of its coordinated effort on Wednesday. The steps include creating a rule under the Clean Air Act that would establish tough engine and fuel standards for U.S. flagged ships. The proposed rule would harmonize with international standards and lead to improved air quality throughout the country.
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.
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.
Now, I’m no Bob Villa, but as a new homeowner who has to replace his roof, I have been looking into environmentally friendly alternatives to either asphalt or “premium” wood. And Enviroshake definitely falls into the first category. Made primarily of reclaimed materials, Enviroshake might just be the answer. Read the rest of this entry »
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.
The prospect of green jobs has proven very attractive to Californian job seekers. According to a survey released this week by the Vote Solar Initiative, a solar advocacy group, more than 5,400 people are participating in solar job training programs this year in the state.
“It is clear that Californians of different economic and educational backgrounds are all looking to solar to provide much-needed career opportunities, and the state’s training institutions have stepped up to meet that rising demand,” said Claudia Eyzaguirre, the author of the report, in a press release.
But it’s not clear whether the state will have enough jobs to support these trainees. Part of that will depend on the kinds of jobs they are training for.
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.
Move — to Louisiana:
According to SolarPowerRocks! Louisiana has a state tax credit of 50% for solar roof installations, the most generous state subsidy for solar — Combined with the 30% Federal tax credit for solar that we all get now; (you knew about that, right?) so in Louisiana you can put a solar roof up, paying only 20% of the cost: (30% + 50% = 80% off).
The way this credit is designed it will benefit modest homeowners the most. If you need a $25,000 system, you get the full 50%. If you need a larger system you get less than 50%, because it maxes out at $12,500.
So, if you have ten plasma tvs and a pool pump and run the A/C day and night, you won’t get as much help with running all that…but

‘Any plan to switch from gasoline to electricity or biofuels is a strategic decision to switch our dependence from foreign oil to domestic water’.
So says Dr. Michael Webber of the University of Texas at Austin in an interview with Steven Lacey on the Inside Renewable Energy Podcast this week.
Webber comments on the links between water and energy, the potential conflicts, but also about the potential opportunities which arise when you start to understand these links and realize that saving water saves energy, and saving energy saves water.
