How Green is Biomass Energy?
When you think of where energy comes from, you might picture a power plant or maybe wind mills. You probably wouldn't think of a pile of 12 tons of almond shells.

Reporter's Notes: Cow Power Not Cutting It
A handful of dairies across California are capturing the climate change emissions produced by their cows. But they're running headlong into another environmental problem.

Reporter's Notes for Energy Storage: The Holy Grail
Energy storage (through batteries) is something we use everyday in our cell phones and computers. So it may be a little surprising that when it comes to the electric grid, storing energy is something that's rarely done.

Editor's Notes: Race for Renewables
Where did California go wrong? And as other states try to learn from its lessons, does the Golden State have any hope of reaching its next ambitious target – 33 percent renewable by 2020?

When the Sun Don't Shine and the Wind Don't Blow
In a world energy landscape dominated by coal, gas, oil, and nuclear, renewable energy sources such as wind and solar don't stand a chance if we can't find a way to store energy when the sun doesn't shine and the wind doesn't blow.

Reporter's Notes: Building an Artificial Leaf
When I began this story, it seemed pretty simple. I'd heard that scientists at Lawrence Berkeley National Lab were working to mimic photosynthesis and create a man-made version of the process that could supply us with renewable energy.

Those Intermittent Renewables – Part 2
"We believe energy storage is the next big thing," says Craig Horne, CEO of EnerVault, a Sunnyvale startup. His company is developing a battery that could help solve a renewable energy problem (check out our previous post): how to keep electricity flowing when we need it, even as more of it comes from sources we can't control. Horne was a panelist at a UC Berkeley-Stanford sponsored CleanTech Conference about energy storage held last week at Berkeley's Lawrence Hall of Science.

Those Intermittent Renewables – Part 1
When it comes to renewable power, California has had one main message: bring on the solar power, bring on the wind turbines! California and the country are heading fast towards a clean energy future. But renewables aren't perfect.

Reporter's Notes: Smart Grid at Home
I've never paid much attention to my electric meter. For most of us, it's just that box on the side of the house with a small white disk spinning inside, keeping track of our energy use. But over the next three years, all the meters for PG&E customers will be getting a major upgrade to a new, digital SmartMeter.

Reporter's Notes: Big Solar on the Ballot
Proposition 7 is one of the green propositions– in more ways than one. The amount of cash that's being spent on this so-called Big Solar initiative is prodigious. It is one of the most expensive measures on the ballot.

Have sewage, will travel
Unless our sewage happens to end up in the Bay and in the headlines, most of us probably never give a second thought to where our wastewater is headed each time we run the tap or flush the toilet. To learn more about the travels of sewage, I took a tour of the Las Gallinas [...]

The Right to Sunlight: Solar vs. Redwood Trees
In Silicon Valley, a battle between neighbors has turned into a different kind of face off: solar energy versus trees. It turns out that growing redwood trees can actually be a crime in California, if they block solar panels… as one couple in Sunnyvale found out the hard way. David Gorn reports on a new [...]

2007 Energy Bill a Mixed Bag
It would be easy to think that the 2007 Energy Bill, signed by President Bush at the end of last year, was all about automotive fuel economy. The legislation that requires fleet-wide average fuel economy for cars and light trucks to reach 35 miles per gallon by 2020 has generated a lot of buzz. On [...]

The New Clean Tech
If investment is any guide, California's renewable energy companies are leaping into the new year. Investors poured billions of dollars into clean tech in 2007 to catapult green technologies to market. In the first three quarters of 2007, U.S. venture capital firms invested $2.6 billion in clean tech companies. That's compared with $1.8 billion for [...]
