When "Miracle on 34th Street" hit the silver screen in 1947, 8-year-old Susan Walker, played by Natalie Wood, got her holiday wish when Kris Kringle gave her directions to the new home she asked Santa Claus to deliver. If the movie were written today, Susan would probably ask for an energy efficient home with ENERGY STAR appliances and solar panels.

Like Kris Kringle, Habitat for Humanity has been making children's dreams come true since 1976. But unlike Santa, Habitat delivers presents to families year round. To date, the organization has built over 350,000 houses around the world, providing close to 2 million people with safe, affordable and now energy efficient housing.

To make these homes even more environmentally friendly, PG&E created the Solar Habitat Program in 2005. So far, as part of the partnership with Habitat for Humanity, PG&E has funded solar installations on 260 homes for hard-working families. The average solar system produces 300 kWh of clean, renewable energy each month, saving participants about $500 a year. In addition, PG&E employees have donated more than 7,000 hours of their time working on Habitat for Humanity job sites.

Just last week, PG&E volunteers, including corporate officers and CEO Peter Darbee, spent the day at a Hunters Point construction site, working on one of seven four-bedroom homes. In addition to other duties, the crews worked to install and hook up eight solar panels on one of the homes. 
 
"It's impressive to see first hand how Habitat for Humanity constructs these quality homes with the help of volunteers from the community," said Darbee. "This is an extremely organized operation that allows those of us who are volunteering to make a real contribution to the construction of these homes."

Thanks to Habitat for Humanity and its many contributors, the spirit of 34th Street lives on as families get their 21st century, energy-efficient miracles year round.

If Jimmy Buffett were writing a theme song for PG&E's renewable energy department, his lyrics might read, "Mother, Mother Ocean: I have heard you call. I wanted to pull the power from your waters since I was three feet tall."

Looking to add to its diverse power mix, Pacific Gas and Electric Company (PG&E) has just signed an agreement with the U.S. Air Force that will let the utility investigate the feasibility of a wave energy project off the coast of northern Santa Barbara County near Vandenberg Air Force Base. The project is part of the PG&E WaveConnect™ program, which includes a pilot study underway in Humboldt County.

PG&E has filed a preliminary permit application with the Federal Energy Regulatory Commission to study the southern site for three years. If findings are favorable, the utility could seek a license to install wave energy conversion devices capable of producing as much as 100 megawatts of electricity. The clean power would feed into the existing electrical grid at Vandenberg Air Force Base, which in turn is connected to the PG&E grid.

Experts believe that wave energy off the 745 mile California coastline could produce more than a fifth of the state's energy needs. The Santa Barbara County Community Environmental Council's renewable energy blueprint calls for more than eight percent of the county's future energy mix to come from the ocean. But there are many hurdles to jump before arriving at those targets, including environmental and land use concerns,  grid connections and design evolution.

"You can't develop a technology unless you can test it," said Roger Bedard, ocean energy leader with Electric Power Research Institute. "In this country, we are challenged with inferior infrastructure in testing ocean energy devices. PG&E's WaveConnect™ projects will provide the infrastructure needed to test and refine emerging technologies."

Throughout the process, PG&E will continue to work closely with local communities and elected officials to understand and address their interests and concerns. The project is expected to have no significant impact on existing coastal activities such as surfing, hiking or whale watching. Development will only move forward if technical studies support its feasibility and if environmental studies show that the project will not have significant negative environmental and economical effects.

Currently, the Earth's oceans produce roughly 300 megawatts of electricity from various devices that convert energy from water movement or the natural temperature and salinity changes into usable power. Next year that number is expected to skyrocket when a 250 megawatt seawall dam comes online in South Korea. But wave power will continue to lag other renewable technologies without development assistance.

Ultimately, PG&E's WaveConnect™ projects will help emerging technology companies develop reliable and cost-effective wave energy devices, find funding and help PG&E and other utilities bring this innovative new source of clean energy to customers.

"If a utility is going to make it happen in this country, it's going to be PG&E," Bedard said.

Several items relating to the business and technology of clean energy and the environment caught our attention this week:

General Motors will launch the Chevrolet Volt "extended range" electric car in California next year with some of the vehicles going to utility fleets in two-year demonstration projects at PG&E, Southern California Edison, Sacramento Municipal Utility District and also the Electric Power Research Institute. The demonstration project also aims to set up 500 charging stations. The Volt is designed to drive 40 miles on electricity; when the lithium-ion battery runs low an engine/generator extends driving range to more than 300 miles.

Los Angeles Mayor Antonio Villaraigosa will set up an electric vehicle infrastructure to lure battery and charging station manufacturers, create green jobs and become "the capital of the electric car." The city and partners plan to update 400 existing charging stations and add 100 more around the region to be ready by fall 2010. Partners include Southern California Edison, Los Angeles Department of Water and Power, Southern California Power Authority, automakers and other cities.

Hybrid garbage trucks soon may be lumbering down your street. New York and a few other cities are testing diesel-electric hybrids, with companies like Freightliner, Navistar, Mack, Crane Carrier and Peterbilt joining with electric motor developers Azure Dynamics and Eaton. New York is testing a 36-ton garbage collector built by Mack Trucks and three other hybrids from Crane Carrier. After a year of testing, the city's sanitation department will pick a winner and begin buying 300 trucks a year with fuel consumption cut by about 30 percent.

Several stories on the science and politics of global warming caught our attention this week:

The world's two largest polluters have agreed to work together to lessen their greenhouse gas emissions. A joint statement released this week claims that U.S. and Chinese scientists and engineers will join forces to speed the widespread use of electric cars, energy efficient buildings, and "coal-fired plants that don't pump out gases that cause global warming." The agreement left out how much each country will contribute to emissions cuts.

A recent University of Saskatchewan study asserts that roughly 12,800 years ago, it only took six months to turn Europe's climate from warm and sunny into an ice age. Researchers previously believed the freeze took place over a much longer period. Lead researcher William Patterson put the new findings into perspective by saying the temperature change would equate to "taking Britain and moving it to the Arctic over the space of a few months."

Can you imagine an Italy without pasta? A report released by the British Meteorological Office can. The five-year study on the impact of global warming on eating habits in Europe predicts that increasing temperatures and decreasing rain will cause Italy's durum wheat crop to disappear in the second half of this century. The same report warns that Polish wheat and potato crops, French champagne and Spanish fruits and vegetables could also be at risk.

The Forest Service claims our nation's forests can be used as a "carbon sink" where trees absorb carbon dioxide to help slow global warming. Currently, forests store enough carbon to offset about 16 percent of the nation's fossil fuel emissions. But Forest Service Chief Tom Tidwell told the Senate Public Lands and Forestry Subcommittee that the number could change. "Disturbances such as fire and insects could dramatically change the role of forests, thereby emitting more carbon than currently sequestered by tree stands across the country," Tidwell said.

Here are some last-minute tips for a green, affordable Halloween Saturday night, courtesy of Treehugger: Ignore the Halloween superstores and recycle stuff around your home -- clothes, cardboard, aluminum foil, boxes and paint -- to craft nifty costumes like skunks, spiders, fish, face masks and more. Select a walking neighborhood for trick or treat and carry a reusable paper bag or a pillow case for your treats and a second bag for litter. After the big night, host a costume swap party or donate costumes to a children's hospital for dress-up days. Happy Halloween!

Jeans giant Levi Strauss & Co. wants you to treat their clothes with the environment in mind. Working with Goodwill stores, Levi Strauss will sew tags into all of its clothing instructing buyers to donate the items when they're no longer needed, Green Inc. notes. The tags will also encourage customers to wash their clothes in cold water and dry them on a clothesline when possible to save energy. Clothing makes up a significant portion of the 23.8 billion pounds of textiles in U.S. landfills each year.

More on clotheslines: There is no longer a U.S. manufacturer of wooden clothespins; we import them from China and sell them as novelty products. Eighty percent of U.S. households have a tumble dryer and millions more go to the laundromat. Dryers account for 3 percent of household power, not including laundromats, hospitals, colleges and so on. The Project Laundry List organization figures we could save 10 percent on energy costs if we did the laundry the old green way -- cold water, line dry, no bleaching or ironing. Maybe Project Laundry List can team up with Levi Strauss and Goodwill.

San Francisco may install dozens of wind turbines to help the city achieve its goal of becoming carbon neutral by 2030. Wind turbines could be built in Golden Gate Park, on Twin Peaks, the Civic Center, Ocean Beach and other locations to help educate residents about the renewable energy source. A city wind power task force recommends developing a wind map to indentify the best sites. Other big cities also are eyeing wind programs. Boston has turbines at Logan Airport and New York Mayor Michael Bloomberg has talked about installing them on skyscrapers.

A partnership between the California Department of Education and PG&E has selected Berkeley High School to establish a New Energy Academy within the school to help prepare students for the growing field of green energy. The Academy will include math, science, technology and engineering in addition to other subjects. The new program will also be offered at Edison High School in Fresno, Foothill High School in Sacramento, Independence  High School in Bakersfield and Venture Academy in Stockton. The utility industry also could benefit from the program. Forty percent of PG&E's 20,000 employees are eligible to retire within the next five years, and it wants to make sure it will be able to replace those workers.

California Gov. Arnold Schwarzenegger is a real bear on energy conservation at home. "I have major fights with my kids," he said in a recent talk. Recalling his experience growing up in Austria after World War II, he said everyone was careful to save electricity and water. His children, however, like to take 15-minute showers. So he warned if they showered beyond five minutes, they will be grounded. His final penalty: if they sneak past the deadline, the governor promises to install a device which only allows you to shower for five minutes and then it turns off automatically. Listen to Dad!

Several items relating to the business and technology of clean energy and the environment caught our attention this week:

A solar installer company and the Dutch bank Rabobank are jointly building battery charging stations on Highway 101 between San Francisco and Los Angeles for Tesla Motors' electric roadsters. The $109,000 sports car has a range of 250 miles. Five charging stations set up by SolarCity will be at Rabobank branches in Salinas, Atascadero, San Luis Obispo, Santa Maria and Goleta. The bank will pick up the tab for the electricity, about $4 for a full charge.

Update on the bag wars: The San Jose City Council votes to outlaw most plastic and paper shopping bags and calls on other cities in Silicon Valley to support the ban. The ordinance, which would take effect in 2011, would prohibit stores from giving out free plastic bags but would allow paper bags with at least 40 percent recycled materials, but only for a fee. Meanwhile, Ireland, the first nation to tax plastic bags, plans to double the charge to 44 euro cents (59 U.S. cents) per bag to reinforce the deterrent.

The California Energy Commission proposes the nation's first energy efficiency standards for televisions, effective in 2011 with tougher standards to follow in 2013. The rules would save about $8.1 billion on Californians' electricity bills over 10 years, or $30 a year per household. The CEC is concerned about the growing demand for electricity-guzzling, big-screen sets. TVs account for 10 percent of the state's residential power use.

Several items relating to the business and technology of clean energy and the environment caught our attention this week:

Engineering and construction giant Bechtel Corp. is moving into the solar energy business, joining with BrightSource Energy to build a 440-megawatt project to supply electricity to PG&E and Southern California Edison. Bechtel Enterprises will take an equity stake in the Ivanpah Solar Electricity Generating System and handle engineering, procurement and construction. The project is expected to get underway in 2010.

Search engine giant Google plans to develop a mirror technology to lower the cost of building solar thermal power plants. The company aims to cut the cost of making heliostats, the fields of mirrors that track the sun, by a least a factor of two, "ideally a factor of three or four," says Bill Weihl, green energy czar at Google. The company also is working on running gas turbines on solar energy rather than natural gas to reduce the cost of electricity.

The first "Global Cleantech 100" list of private clean technology companies "regarded as having the potential and likelihood to achieve high growth and high market impact" arrived this week, with the U.S. topping the list with 55, followed by the U.K. with 13 and Germany 10. The list was organized by San Francisco-based Cleantech Group LLC and Britain's Guardian newspaper and represented "the collective opinion of hundreds of leading experts from cleantech innovation and venture capital companies." Northern California companies included BrightSource Energy, Imara Corp. Silver Springs Networks, Serious Materials and Tesla Motors.

Several items relating to the business and technology of clean energy caught our attention this week:

• Alaska is considering building small nuclear reactors to power some of its cities and reduce energy prices. A Fairbanks developer is proposing a 25-megawatt reactor designed by Hyperion Power Generation Inc. of New Mexico. The village of Galena has been working with Toshiba Corp. to build a 10-MW reactor. Both reactors would be buried underground. Alaska Gov. Sarah Palin supports the concept.
• Canada's Ontario province has dropped a $22.4 billion plan to build a nuclear power plant that would have been the first nuclear reactor constructed in North America in three decades. The province cited rising costs and uncertainty over the financial health of government-owned Atomic Energy of Canada Ltd. Ontario gets more than half of its electricity from nuclear power.
• SunPower Corp. and Wells Fargo Bank will partner to fund $100 million of solar electricity in businesses and public buildings, beginning with projects at the University of California-Merced and a waste water agency in Riverside County. Wells Fargo will finance and own the systems and SunPower will build, operate and maintain them. Customers will buy the electricity from SunPower.

Several items relating to the business and technology of clean energy caught our attention this week:

• San Francisco has passed a law requiring all homes and businesses to recycle and compost. Mayor Gavin Newsom says if everyone puts all the garbage, food scraps and other waste in the correct color-coded buckets, the city's recycling rate would rise to 90 percent from the current 72 percent. There's a cap of a $100 fine for homes and small businesses, but Newsom says the goal is to heighten public awareness.
• Smart Sewers? Yes, we will have them right here in San Francisco. The city's Public Utilities Commission and IBM Corp. have teamed up to install software to monitor maintenance of the city's 1,000-miles of sewer pipes and pinpoint potential water pollution, overflowing storm drains and other underground emergencies. 
• Chicago's 110-story Sears Tower, the tallest building in the Western Hemisphere, will get a $350 million "green" retrofit that aims to reduce electricity use by 80 percent and water consumption by 40 percent. The makeover will include gas boilers with fuel cells to generate electricity, heat and cooling; solar panels to heat water; wind turbines, if possible; "green" roofs; new lighting systems; and water conservation in new restroom fixtures, among other energy-saving features.
