Nano carbon Graphene is already being produced in decidedly non-nano quantities by Ohio-based Angstron. Yet the atom-thick nano-material was discovered so recently that researchers are still in the process of discovering what to use it for.

Graphene is an extremely low density material, almost an atomic-scale chicken wire made of carbon atoms and their bonds. It has been the focus of much research because of its exceptional electrical, mechanical and optical properties. It holds great promise in renewable energies.

Among the so far underutilized advantages Graphene offers are that it is fifty times stronger than steel, and it has five times the conductivity of copper, with only one quarter of the density.

Just the other day, I wrote that it was a great time to go solar, especially due to the great rebates and discounts on solar technology. Apparently, I jumped the gun and was a few days early. A new report by Lawrence Berkeley National Lab — “Tracking the Sun II: The Installed Cost of Photovoltaics in the US from 1998-2008” — shows a significant decrease in solar costs over the last ten years and shows that now is a great time to go solar.

Vice President Joe Biden just revealed a plan to make Berkeley First available nationwide. Yesterday at his Middle Class Task Force meeting Biden proposed the way to make solar roofs easy for everyone to afford with virtually free solar panels. If you now pay your current electricity bill and own a home, that’s literally all it takes to go solar under municipal tax assessment financing.

That’s because his plan; detailed in Recovery Through Retrofit simply makes the very successful Berkeley First municipal tax assessment financing a Federal program, called PACE (Property Assessed Clean Energy), funded nationwide through the Recovery Act.

Homeowners in Southern California could now go solar for as little as $10,000 for about a 3.5 KW - 4 KW solar roof.

If you do solar estimates in Berkeley, you start feeling left out that you don’t estimate solar roofs in San Diego. Rebates for our whole state are decided based on optimum solar conditions. That optimal spot? Southern California.

So if you go solar in Berkeley and install the exact same kilowatts-worth of solar panels as someone in San Diego, you won’t get as good a state rebate from your utility.  They just have better sun down there, and it’s the standard by which all other sun is judged—at least by the California Solar Initiative’s Expected Performance Ratings.

We’ve made up for that by inventing new ways to lower solar costs—like One Block off the Grid (1BOG)— which aggregates homeowners into groups to reduce solar costs.

But now our own San Francisco-based 1BOG is taking aggregated solar purchasing to sun drenched Palm Springs, Palm Desert, Desert Hot Springs and Coachella - the very places that already qualify for the best rebates per kilowatt in the state!

92% of people think we need to develop and use solar power, but less than 1% of US power is from solar. Where are the gaps?

I can identify three main ones, but they seem to be getting addressed more and more by a wide variety of parties — public, private and non-governmental. So, what is left?

A major new survey has revealed that nearly 50% of all US consumers would consider buying a ‘green’ cell phone, but only if key factors such as the price, features, and performance were equivalent to other phones.

According to the poll of 1,000 American adults carried out by ABI Research, just 7% would be willing to pay a premium to go green, a figure that may cause cell phone companies to think deeply before investing heavily in environmentally friendlier models.

Speaking about the findings, industry analyst Michael Morgan said, “These survey results mean that almost half of those surveyed were at least committed in principle to use of a green handset. However the public is largely uninformed about their availability: only 4% said they were ‘very familiar’ with green handsets.”

The new green-themed Reclaim made by Samsung is more than your standard phone with slick green branding — though there’s a bit of that too.

What’s green (or blue), smaller than a deck of cards and will remind you to unplug the charger from the wall after charging? The Reclaim, the new green-themed smart phone made by Samsung for Sprint, is loaded with a bunch of green content, a handful eco-conscious accessories and an attention to sustainable packaging that make it more “green” than most other phones out there.

But you can’t just slap a case made from forty percent corn plastic, dip it in green paint and call it green, can you? The folks at Sprint sent me the new Reclaim so I could answer those questions myself. Read the rest of this entry »

You knew you keep a fire in a box in your laundry room, right? Not only is that kind of a scary thought, but it’s an extremely inefficient way to dry clothes; lighting a fire every time you turn on the clothes dryer. Lint catches fire all the time. But even worse, that natural gas emits carbon dioxide and is likely the second most extravagant energy expenditure in your home after the fridge.

We can do something about the fridge by buying an Energy Star rated efficient one, but until now, inexplicably, clothes dryers have not been rated under the Energy Star program.

You have to wonder why there has been so little move to improve energy efficiency in the second biggest energy guzzler in most homes…in a nation that uses 25% of the world’s energy.

Here’s a company that can make a clothes dryer 50% more efficient with a heat exchanger. Hydromatic. So why has their idea not been incorporated into clothes dryers?

A new tool in Google Earth shows you the “effect” of climate change in your area.

Using Google Earth, you can look at climate effects under three different scenarios — 1) Confronting Climate Change — “with Al Gore”, 2) IPCC High Emissions Scenario, and 3) IPCC Low Emissions Scenario. Other new tools let you examine other aspects of climate change and how to adapt to climate change.

Attaining an EnergyStar rating is crucial for companies creating home electronics and appliances if they want to appeal to the eco-minded or cost-conscious consumer, which these days can be found in virtually every North American and many European households. New standards have just been released (on September 3rd) that encourage television manufacturers to reduce their carbon footprint and the size of their screens.
