Biggest California CO2 emitter is…

Posted by: Peter Henderson

The biggest greenhouse gas emitter in California isn’t in California.

A string of PacifiCorp power plants are the biggest emitters of carbon dioxide included in the state’s 2008 inventory of carbon sources tied to state use.

California aims to start a cap-and-trade system for carbon pollution in 2012, if it is not preempted by a federal plan, and emissions reports by big power plants and the like represent a step toward that goal.

In-state and out-of-state power plants are roughly equal in the amount of carbon dioxide they produce, and together account for about a quarter of the state’s emissions. A weak economy has raised the stakes for California’s energy plans, and Gov. Arnold Schwarzenegger recently vetoed legislative renewable power goals that would have limited out-of-state supply. Instead he set a target with an administrative order that was less restrictive.

The biggest in-state California sources of CO2 were Chevron, Shell and BP refineries, accounting for under 5 million metric tons of carbon dioxide equivalent each in a chart of top emitters released by the California Air Resources Board. (One PacifiCorp plant in Wyoming had emissions over 15 million metric tones.)

The biggest source of emissions in California, though, is transport, and the 38 percent of emissions from that is not included in refineries’ totals. The Air Resources Board plans to give an update of its cap-and-trade program on Tuesday.

Water rights make El Centro an oasis

Posted by: Nick Carey

ROUTE-RECOVERY/

If you head east to El Centro from San Diego, Interstate 8 takes you through arid scenery, climbing to 4,000 feet through barren mountains so fast that your ears pop. Then comes the oasis.

As you head down rapidly out of the mountains once more toward El Centro you hit a sign that tells you that you have reached sea level. Green fields and palm trees, stacks of hay drying in the fierce sun -- 90 degrees Fahrenheit even in November -- surrounded on all sides by rocky hills and the desert.

We knew before coming here that this was an agricultural region, but the lush greenery amid such a scorched landscape took us by surprise. This is where much of America's lettuce, spinach and other vegetables come from in the winter. There are also large cattle feed lots here too, which launch a frontal assault on your olfactory system long before you see them.

ROUTE-RECOVERY/

But you don't have to wander far from the fields to find the desert and its fine reddish, beige sand and realise just how incongruous the lush green fields are. Particularly when you feel the sun beating down on you when much of the northern hemisphere is already feeling the first cold of winter.

This is all made possible by water rights this area has from the Colorado River. As this part of the desert is below sea level in some parts, the water flows downhill and an irrigation system delivers it to 500,000 acres of farmland.

Without this water the fields would no doubt revert to desert in short order.

Some 97 percent of the water diverted to the area around El Centro goes toward farming and city manager Ruben Duran says the city is looking at ways to conserve water in a place where "mild dehydration is a natural state for most people."

But while people here talk in terms of conservation and wise use of water, they can also remind you that water rights in El Centro and Imperial County have been upheld twice by the Supreme Court and that no one can take them away.

"Water is always a concern," said Tim Kelley, head of the Imperial Valley Development Corporation, a public private partnership set up to diversify the local economy. "But those water rights belong to us. And if you don't like it, you can take us to court."

Solar heads to developing world

Posted by: Laura Isensee

While solar power has investors on Wall Street seeing green, countries in the developing world also see a bright future in solar technology.

They believe solar power systems that convert sunlight into electricity can help power developing areas without going the route of dirty coal-fired power plants.

Solar companies like China’s solar panel maker Suntech and California-based eSolar, have recently announced forays into the developing world.

Suntech is teaming up with Pakistan’s alternative energy development board, which the company’s chairman and chief executive Zhengrong Shi called “a clear example of the promise of solar energy.”

Solar thermal company eSolar said last week that it is expanding in Africa and earlier this year it partnered with an Indian company to build solar power plants in India over the next 10 years.

And a $400 billion euro plan is gaining steam to power Europe with Sahara sunlight, despite critics.

Today’s top solar market — and lots of profits — are found in Germany while the United States and China are fast-growing alternative energy sectors. Will countries like South Africa join their ranks one day? How will countries and governments make good on the promise of solar energy for the developing world?

Could patents bring solar power companies more revenue?

Posted by: Laura Isensee

The high tech industry regularly sees lawsuits fly over intellectual property rights.

Time will tell if clean technology will see a similar play, but a settlement this week between California-based solar power company SunPower Corp and SunLink Corp may shed light on things to come.

In February 2008, SunPower sued SunLink, saying SunLink had violated patents protecting several of SunPower’s rooftop systems. Under the settlement, SunPower licensed its patents to SunLink but did not disclose the financial details.

Some believe that solar power companies who successfully defend their intellectual property could win additional revenue streams. That could benefit SunPower and innovative companies both with upstream and downstream technologies, Deutsche Bank analyst Steve O’Rourke wrote in a note.

We were wondering what role readers think IP and patent lawsuits will play as the solar industry continues to develop. Do you think they will help bigger companies defend their market share? Or could a litigious environment stifle newcomers to the industry?

Schwarzenegger household green plan: short showers, hydrogen Hummers

Posted by: Peter Henderson

Here’s some advice for Californians who think Governor Arnold Schwarzenegger’s climate change policy goes too far: just be happy you’re not his kid.

Before he became a body builder, before he was the Terminator, and before he turned into the Governator, it turns out that Arnold was the youngest in a family that had no running water and relied on an outhouse. That’s what he told fourth graders who innocently asked about how he spoke to his kids.

“I have major fights with my kids,” he responded, quickly segueing into the difference between post-World War European poverty and the Golden State.

“We had kind of a system where we carried the water from 200 yards away from the well, to our house upstairs to the second floor where we lived, and then my father would wash himself first, and then my mother would wash herself, and then my brother would wash himself in the same water, and then I would wash myself, and it was all dirty, because I was the youngest. So that’s how I grew up because conservation was big in Europe. Especially since I grew up after the Second World War. There was no food, there was little electricity, there were blackouts left and right, there was nothing. After the war was worse than during the war. So we had absolutely nothing,” he said.

And while the Governor now has solar panels to heat the water in his pool and jacuzzi, a hydrogen-powered Hummer, and he recycles, it seems conservation is still BIG — and mandatory — in the Terminator household.

He recalled watching his kids take a stool into the shower to sit and enjoy the hot water — for a long time.

“I’m sitting outside timing it now, and it’s 15 minutes, and still they are in the shower. So I open the shower door and turn off the hot water and then all of a sudden they start screaming, because it is cold,” he said, adding that he had created rules: no shower longer than 5 minutes — or else.

Here’s the three-minute history of Arnold’s conservation conversion, at a Commonwealth Club event in San Francisco:

SolarCity envisions California “solar corridor” for green drivers

Posted by: Laura Isensee

Electric cars can be smooth, quiet and environmentally friendly. But they still need fuel.

Many have asked — and invested according to their answer — whether that fuel will come from batteries, utility grids, curb-side charging stations or some other technology.

Drivers in California have a new option, if they drive a Tesla electric vehicle. And it’s extra environmentally friendly.

SolarCity, which installs residential solar systems, is building a charging corridor between Los Angeles and San Francisco. There will be five 240-volt stations along the highly traveled Highway 101 that will juice up electric vehicles in one third the time of other charging stations. One of the chargers — in Santa Maria — is solar-powered.

SolarCity is working with the U.S. branch of Holland’s Rabobank to install more solar power systems at the stations, which would make the corridor the first to be entirely solar-powered.

We wanted to know if readers think this is how electric cars will roll across the country — with solar power? Or are your bets with battery technology or another type of charging station?

The race for U.S. smart-grid cash

Posted by: Laura Isensee

Utilities across the United States are rushing to a federal stimulus program that is doling out money to create a “smart grid” — systems that will upgrade the electricity grid.

In this story, Reuters correspondent Eileen O’Grady looks at the tough job facing the U.S. Department of Energy: They have to divvy up $4.5 billion in smart-grid money among some 565 applications.

Smart grid technology measures and modifies power usage in homes and businesses and improves grid reliability. Experts envision that it will open the door to a new era with “smart” appliances that turn themselves on and off, electric cars, more renewable energy and more efficiency on power lines.

San Diego Gas & Electric is one of the utilities hoping to launch a smart grid through the federal program and has applied for $100 million in stimulus funds.

Their plan would build micro smart grids at the University of California, San Diego and a residential community in San Diego County. They would work with companies like IBM, Cisco and Itron on the system technologies, software and hardware.

“They not only have to talk with each other but we have to make sure the entire network is secure. So from an intellectual security standpoint, we’ll ensure that we have that set-up, that we have the ability to communicate from one device and we make it seamless for the customer,” said Michael Niggli, chief operations officer at San Diego Gas & Electric.

Another major issue the utility hopes to solve is what happens when energy from renewable resources is intermittent, with its power generated fading or spiking.

“If the wind stops blowing or if the sun has clouds that intervene, so you can be in a situation where the power supply is affected,” Niggli said in a phone interview with Reuters.

“That’s a lot different than what we have today … where it’s like driving a car. If you want to go faster, you push the accelerator.”

Niggli envisions a system where customers can control their home energy use remotely, turning on the air-conditioning from a computer through the Internet or even on  their handset.

Some companies that are partnering with utilities are not putting all their eggs in one basket in the race for the smart-grid stimulus funds.

IBM is working as a vendor with a dozen utilities that have applied for money.

If the smart grid is done right, then customers won’t even notice a difference, said IBM’s Stephen Callahan, who leads the company’s Intelligent Utility Network unit for the Americas.

“Those customers shouldn’t see anything but improvement in cost, reliability, all those things,” Callahan said.

We wanted to know what readers think about the federal program to jump-start smart grid projects. What should the DOE prioritize? What kind of projects would you like to see?

New Jersey has best payback on residential solar in U.S.

Posted by: Laura Isensee

California may be the Golden State, but it’s New Jersey where U.S. residents get the best deal on their solar power systems, new research shows.

A survey by Global Solar Centertried to give an “apples to apples” comparison for the cost of solar power in all 50 states, the center’s chairman Jack Hidary told Reuters.

The common denominator turned out to be the cash payback, or how many years it would take a residential or commercial customer to recoup their investment and start seeing real savings, Hidary said.
“That takes into account the cost of the system, the sun at that spot, the incentives of that region, utility rates. It blends in everything all together,” Hidary said.

The center analyzed the date using new software and found that New Jersey had the fastest payback — 1.5 years — for residential systems, followed by New York and Delaware with paybacks of three and six years, respectively. California tied for fourth place with Maryland, Massachusetts and Wisconsin, all with payback hitting seven years.

Rankings changed when the center looked at commercial solar power systems.

For commercial projects, Colorado, Wisconsin, Hawaii, Ohio and Oregon all share the top spot, with a 1.5 year payback time, according to the survey.

The center also found that solar hot water systems have a one-year payback in sourthern Texas and Florida.

“To put this all in context, five years ago you couldn’t find a state with less than a 10 or 15 year payback,” said Hidary, who also is a board member of the National Renewable Energy Laboratory. He said the steep fall in solar panel prices and more government incentives have helped speed up the return on investing in a solar power system.

Government incentives turned out to be the biggest factor driving the cost of solar systems for  customers, Hidary said. Utility rates were the second biggest factor. In states where power is very cheap, it’s harder for solar power to compete, he added.
Hidary believes one of the biggest uptakes of the study was for the investment community to reassess smaller-scale or distributed solar power systems.

Turning to the sun

Posted by: Natsuko Waki

With oil prices more than doubling from Dec-Feb lows, those who are lucky enough to enjoy the sunshine are turning to the sun as alternative energy, but lingering effects of the credit crisis might be discouraging consumers from turning to this still-costly alternative energy.

Latest statistics suggest that solar applications are up 15% in megawatts compared with last year, according to Bank of America Securities-Merrill Lynch report. However, installations are down by 68 percent.

The bank's analyst Steven Milunovich makes the following observation:

Although these figures imply a soft (and softening) solar market in California, it is likely that customers are deferring installation, both voluntarily and involuntarily. Commercial customers are waiting for financing to improve and for grants to become available, which began in August. Installers tell us that the demand is there, but that financing is holding up installations. We expect some improvement in the second half.

He also thinks that rising electricity rates makes the solar industry makes this too large a market to ignore for investors. Within the sector, solar technology firm SunPower has the leading share, about 30 percent share of completed systems, followed by Sharp and Suntech.

Mickey Mouse meets Mr. Polar Bear at green theme park

Posted by: Nichola Groom

Southern California — home to Disneyland, the mother of all amusement parks — welcomed a new attraction this month. But this theme park has no Mickey Mouse or roller coasters and is housed inside a mall instead of spread out over a swath of space.

Called Environmentaland, it is more of an interactive museum that has taken the environment as its theme.

The goal is to show there are “no free rides in life,” said Eric Ritz, executive director of Global Inheritance. The nonprofit opened the self-proclaimed first environmental theme park this month in Hollywood.

“We promote more along the lines of common sense rather than being green,” Ritz said.

Visitors can ride a see-saw on an energy playground to power up their cell phone, putt on a desert mini golf course and fly airplanes from recycled paper. This past weekend, visitors could arm wrestle a polar bear in a climate change quiz challenge for a chance to win prizes.

Ritz, a 36-year-old former advertising executive and long-time activist, started Global Inheritance in 2002. The nonprofit has passion projects, like Environmentaland, but pays the bills through working with companies like Walt Disney’s ESPN and on events like Fox’s Teen Choice Awards.

Ritz admits the name Environmentaland is “kind of preposterous.”

“But that’s the point,” he added.

He said that the name is a play on words that takes on the idea of theme parks, that are the “poster child of excessiveness,” he said.

Visitors who show a bus or subway pass get free admission; otherwise, there is a suggested donation of $3.

Environmentaland is open at the Hollywood & Highland shopping center in Los Angeles through October 2009. In the spring, the nonprofit hopes to take the theme park on the road to malls in cities like Chicago, New York and Boise.

“When we’re placed on the Earth, we have a certain responsibility to give back or evolve in a very positive way. People go and they take and take and take and they don’t give. If that’s what we do, we’re going to be in a very bad shape very soon,” Ritz said.
