New York City goes green by launching a 100% wind and solar powered billboard this Holiday Season.

As alternative energy continues to be the hot topic in our flailing economy, New York City sets an environmental example by launching Times Square’s first 100 percent eco-powered billboard.

The billboard powered entirely by wind and sun, is the first such sign in New York City. It will be erected by Ricoh Company, Ltd., a Japanese company that strives to be outstanding in all areas of the environment, society, and the economy. Their first eco-signage project dates back to April 2003 in Osaka, Japan.

Powered By Wind Turbines and Solar Panels

The electricity for the billboard will be produced entirely by solar and wind power and stored in 16 batteries. No electricity will be purchased from local power companies.

Sixteen wind turbines and 65 solar panels will produce an average of 98 kwh of electricity per day (93 kwh from wind power and 5kwh from solar). To put the savings into perspective: the same amount of electricity required by an ordinary sign would result in as much as 18 tons of carbon dioxide per year. The batteries can hold four days worth of supply. However if there is insufficient wind or solar power, the sign may not light up, an eventuality that Ricoh readily accepts.

The first innovative step towards stacking cars was the parking structure, where layers of cars could be stacked upon each other. The next innovative step is to actually stack cars up against each other to reduce the absurd amount of space we require for vehicular parking. The concept is a hybrid of car sharing systems, spatial planning, alternative fueling systems, and personal convenience.

Developed by MIT Media Lab students from the Concept Car Design Workshop sponsored by GM, the key behind this concept is the redesign of the wheel and axel. Rather than having a rigid axel, it will actually fold in a way that will allow the car to rotate upwards 90 degrees. In this, the long dimension of the vehicle is perpendicular to the ground while parked. Since each car has the same form and design, they perfectly nest together to reduce surface space consumption. The stackable car will be able to reduce required curbside parking space by about a third to a half. This allows for more sidewalk space, biking lanes, and comfortable city conditions.

Due to the small dimensions, the stacks of cars will be conveniently placed in locations all over the city- where you would normally come out of a building and hail a cab; you can jump in an electric city car and advance to your next desired location. The concept City Car system includes solar paneling on the rooftops of buildings adjacent to the stackable parking depositories. These panels will be the power supply to charge the electric cars while parked.

This car-sharing concept is a solution to the missing link between public transportation and the front door. Often people don’t use public transit due to the time necessary to switch from the subway to the bus to the next bus. Now people can commute into the city, get off the train, jump in a city car, and drive that extra three to ten miles to the office. This is a reasonable solution to a very prevalent problem. Instead of unnecessarily consuming a parking space while in the office all day long, you can use a city car in the morning and evening, while others use it all afternoon; and the convenience of hopping in a city car is what will make this work. In addition, since these cars aren’t personal vehicles and people will be in them on an average of five to thirty minutes, hopefully the new system will encourage people to share rides across town thus influencing our sense of community, status, and ownership.

A Norwegian company called Renewable Energy Corporation (REC) will build the complex, which will be completed in different stages to incorporate wafer, cell, and module production. REC already operates the world’s current largest solar plant in Norway, which produces about 650 megawatts of energy annually.

A solar manufacturing plant would be the first of its kind in Southeast Asia, and REC looked at 200 locations before settling on Singapore. A combination of tax incentives, grants, and a skilled workforce were some of the reasons REC liked it. Likewise, Singapore officials are thrilled about playing center stage in the world’s rush to clean technology. Ko Kheng Hwa of the Economic Development Board explained:

The project will be a ‘queen bee’ to attract a hive of solar activities to Singapore — big companies and young start-ups engaged in research and development, manufacturing and innovation, as well as the supplier ecosystem… This investment will be a tremendous boost to our national drive to develop the solar industry.

Once completed in 2010, the capacity of all the products the plant produces will generate up to 1.5 gigawatts (GW) of energy each year — that’s compared to the total global industry output of 2 GW in 2006. That large of an impact, combined with the 3,000 expected jobs, shines a new light on an emerging area of the world hungry for innovative and clean technology.

Solar thermal power makes electricity by converting solar energy to heat that drives a thermal power plant.

The utility’s plan is to build at least 300 megawatts (MW) of solar thermal in Florida; that’s enough electricity to power about 150,000 homes. It will also help the state reach its goal of cutting CO2 emissions to 1990 levels by 2020 and get 20 percent of its electricity from renewable sources by that same year.

California will get a 200-MW plant that will cover 2 square miles with flat mirrors that track the sun.

FPL’s CEO Lew Hay told Reuters: "The thing we’ve got to make customers understand is that any fossil fuel has a hidden cost that society is paying every day, and that is the cost of carbon. We need to put a price on carbon, by doing so the illusion that coal-produced energy is low-cost will go away."

The project FPL has planned will start out as a 10MW pilot project and eventually grow to be the largest solar plant in Florida. But besides the solar investment, the company is also upgrading all 4.5 million electricity meters used by Florida customers. The replacements will be "smart network" meters that show a digital read-out of electricity consumption, and even give an hour-by-hour record of power use. This will allow customers and businesses to monitor their energy use more closely, and experiment with the most effective methods of efficiency. Other investments will go towards promoting these efforts.

As exciting as this news is, it’s easy to feel down when you learn that FPL’s solar plans for Florida only amount to about 1 percent of the state’s power plant capacity. But clean energy supporters and FPL are still optimistic. Hay pointed out that relatively large commitments to clean energy, like FPLs, will really drive the cost of the technology down.

Already the largest wind power provider, FPL now has its sights on leading the solar market.

Costco – the giant discount retailer – is installing its first solar array on the Kailua-Kona store in Hawaii. A 680-kilowatt solar electric system – big enough to power about 111 Hawaiian homes – will be installed by REC Solar of San Luis Obispo, CA. It’s expected to be completed in the next five or six weeks.

The Kailua-Kona store may save up to a one-third of its electricity costs by producing its own energy from the sun. Costco has more solar planned for other stores, mostly in Hawaii and in California.

A Safeway store in Dublin, CA has started generating electricity from its own solar panels, and the company plans to install systems on 23 of its stores – enough to power about 20 percent of a stores’ average energy use. That’s enough to avoid over 10 million pounds of carbon dioxide emissions (CO2) – a major contributor to global warming.

Efficiency is another part of Safeway’s plan: Since 2005, super-efficient refrigeration systems and LED lights have been installed that have allowed the company’s stores to do the same amount of work using less energy.

Companies may be scrambling to expand their green credentials, but they’re also moving forward because of ample incentives from the states. In Hawaii, commercial photovoltaic systems are eligible for credits of up to $500,000 and net metering laws are in place that allow companies to offset electric bills with surplus power put back on the electric grid. Additionally, the federal government offers a 30 percent tax credit.

Local, state, and national incentives for renewable energy will continue to drive business to do the right thing by making it economically sensible to do so. That, combined with a better brand reputation among consumers and investors, may drive even more companies to choose greener options.

• Moving $16 billion in tax incentives away from oil companies and putting it towards renewable energy.
• New energy efficiency standards for appliances and building codes.
• The creation of a Solar Energy Industries Research and Promotion Board to raise national awareness of solar energy options. The program would be funded completely by a portion of solar industry revenues, with no appropriations authorized.
• A modified 4-year extension of the wind power Production Tax Credit (PTC) that limits the credit to 35 percent of wind project costs.

Not in the bill is an increase in the Corporate Average Fuel Economy (CAFÉ) standards (a.k.a. “fuel efficiency”) that was a hot topic as the session came to a close. By avoiding a vote on CAFE standards, Democrats avoid public in-fighting with fellow Dems from auto industry states, notably Commerce Committee Chairman John Dingell (D-MI).

The Senate already approved an increase in fuel efficiency back in June, which will be just another piece of the Senate bill to be reconciled with the House version in conference committee this fall. In addition, the White House has threatened to veto any legislation containing a renewable energy standard.

But despite solar power being vastly under-represented in the Sunshine State, Governor Crist is awfully excited about nuclear power (even lumping it together as “renewable” along with wind and solar in his remarks at the Florida Summit on Global Climate Change).

Nuclear supporters argue that it would be expensive at best and impossible at worst to meet the 20 percent renewable energy goal with only solar, wind and biofuels. The President and CEO of Progress Energy Florida, Jeff Lyash, told the St. Petersburg Times the only way the Governor’s goals are achievable is with nuclear.

Others aren’t so optimistic about a nuke-rush in Florida. It would take at least 10 years and billions of dollars to get the necessary state and federal approval and construct a new plant, and that money could go much further by making energy use as efficient as possible and by developing truly clean, renewable sources of energy like solar power. Dale Bryk of the Natural Resources Defense Council explained,

"If you spend all the money that you have to develop global warming options on nuclear, you’re going to do the least you can possibly do to solve the problem by spending the most money.”

Governor Crist is doing better on the coal front. He, along with others, pressured Florida utilities to drop an 800 megawatt (MW) coal-fired power plant because of concerns over its global warming pollution. In June, the Public Service Commission (PSC) rejected a proposal by Florida Power & Light to build a 960 MW coal plant near Everglades National Park. The PSC based its 4-0 vote in part on concerns about the plant’s climate change emissions – marking the first time that global warming has ever played a role in the body’s decision.

A California-based startup company called Cleantech America LLC plans to build the solar farm. The company develops utility-scale solar plants and wants to commercialize photovoltaic (PV) solar technology in order to slow global warming and increase America’s energy independence.

The San Joaquin Valley Customer Choice Solar Farm (hopefully they’ll think of an acronym or something) is expected to be completed in 2011 and will cover 640 acres. That’s far larger than North America’s largest planned solar power plant in Nevada and double the size of the world’s largest solar project planned for Germany.

Cleantech’s CEO Bill Barnes told CNN that this project will make California the world’s clear leader in solar power, catapulting it ahead the current powerhouse, Germany:

“We’re pretty confident that solar farms on this scale are going to have an industry-changing impact. We think it’s the wave of the future. This scale of project, I think, creates a tipping point for renewable energy…the impact for it will be similar to the impact of the computer chip.”

The San Joaquin Valley is well-suited for a large solar project, according to Cleantech. Its good sun resources allow for power to be generated close to where it is needed and reduce the poor air quality that plagues the area. Producing power locally will also save on transmission costs that can drive up the price on out-of-state electricity.

According to the EPA, an 80 MW solar power plant would avoid up to 450 pounds of toxic mercury emissions and 100 million pounds of carbon dioxide emissions each year – a major contributor to global warming. That’s the equivalent of keeping 20,000 vehicles off the road. The University of California at Berkeley found that the San Joaquin Valley could see considerable job creation if the growth of solar projects in the area continues; up to 1,040 installation and maintenance jobs and 1,600 solar manufacturing jobs may be created, mostly in the local vicinity.

Some significant hurdles remain. Namely, choosing one of five sites under consideration to locate the solar power project, connecting it to the transmission system, and contracting with a manufacturer to supply the PV panels. The California Energy Commission must certify the solar plant as a renewable energy source that doesn’t create pollution, and a number of local permits must be obtained.

Cleantech will partner with the California Construction Authority to build the plant and sell the energy to the Kings River Conservation District, a public agency that is the water management arm of the San Joaquin Valley Power Authority. The Power Authority was created in late 2006 to reduce the power now bought from investor-owned utilities like PG&E and Southern California Edison.

Increasingly, homeowners and businesses are getting bank loans and even grants to install solar and wind power systems on the site of their property. The Database of State Incentives for Renewables and Efficiency is a great place for homeowners to start. It is common to now receive an incentive to reduce the cost of these systems from 25 to 40%, depending on location, of course. The state of Oregon now has 50% Business Energy Tax Credit for all renewable project costs. Not only does this incentive make alternative, local power generation an affordable option, but in provides individuals, families, and groups with the possibility of claiming energy independence from the electric grid.

Following is a supreme example of how the business management of renewable energy systems is gaining strength and incentives. The largest investment bank in the U.S., Morgan Stanley, will finance and own the PV systems that are to be installed atop 7 Wal-Mart stores in California. The way this works is that Morgan Stanley signs on as a financing partner of SunPower, the supplier, designer, installer, and maintenance supplier of the systems. Morgan Stanley pays for the system up front and the customer pays for it over a long period of time, as opposed to 100% up front. This means low investment risk and instant availability. Big business is seeing green in dollars returned by investing in alternative energy that makes good business sense to them. Not only is it just good business because it looks good and tops their environmental checklist, but it’s economical. Tiffany’s, for example is expecting a $500,000 annual savings on the 1.3 megawatt solar installation divided between 2 distribution centers in New Jersey.

I am not writing to debate the politics of appreciating solar value, market value due to commercial demand, and increasing utility prices; I’d just simply like you to appreciate that there is a greater demand. According to Solar Buzz, “Over the last 20 years the cost of solar energy systems has come down seven fold…” According to The Economist, “Global investment in renewable power-generation, biofuels and low-carbon technologies rose from $28 billion in 2004 to $72 billion in 2006.” If you think about it fundamentally, it makes sense that there be more value at a cheaper cost to us in something that is renewable. These businesses are not signing the Declaration of Energy Independence (yet), but they are partially acting on the economical incentive present. Even though designing these stores and warehouses to maximize on natural light might be the most energy efficient option, investing in solar to power the devices within this space has to be applauded.

Oregon’s legislative session went out with a bang. Building on the renewagble energy standard passed earlier this summer that requires 25 percent of energy to come from renewables by 2025, this week Governor Ted Kulongoski signed key solar power policies that will continue to encourage solar manufacturing and solar energy systems in the state.

For starters, the tax credit for solar power projects jumped from 35 percent of project costs to 50 percent. A tax exemption passed for solar net metered systems, and a provision requiring public buildings to set aside 1.5 percent of their construction budget to fund onsite solar power technologies also made it through.

Jon Miller, executive director of the Oregon Solar Energy Industries Association, explained why solar power is good for Oregon:

It's another example of how we're growing manufacturing in the northwest. We're now a powerhouse in the United States in solar manufacturing. Oregon's established and educated semiconductor workforce makes it a natural fit for the solar PV industry.

Solar business is booming in Oregon. Indeed, two manufacturers (Germany-based SolarWorld AG and California-based Solaicx) have already committed to the state, and overall the solar industry is growing more than 30 percent annually. Oregon ranks 5th in the U.S. for solar hot water systems and in the top 10 for photovoltaic (PV) systems. By 2009, Oregon is expected to be the largest producer of PV cells in the U.S.

Solaicx, a manufacturing company that produces high-efficiency silicon wafers for photovoltaic solar power, has announced a new facility planned for Portland, Oregon.

The 136,000-square-foot plant will produce silicon ingots, which are logs of pure silicon that get heated to high temperatures and sliced like lunch meat to make silicon wafers. The wafers are the semiconductor materials in solar panels. The process for producing and processing silicon wafers for solar power is difficult and expensive, but Solaicx claims it uses silicon more efficiently and thus creates a more cost-competitive product.

The plant will provide about 100 new green collar jobs and, by the time it reaches full capacity in 18 months, may produce enough material for 142 megawatts of solar panels.

Why Portland? The Oregon Department of Energy created a Solar Energy Working Group charged with developing and implementing a strategic plan to lure clean tech companies to Portland. Jeff Jones, Vice President of Manufacturing for Solaicx, said the state’s incentives were key in the company’s decision to locate there:

"We looked at the state of Oregon's generous financial incentives for renewable energy and Portland's deep base of skilled labor in silicon manufacturing, and decided that the port is an ideal place for our continued growth as a company. This welcoming atmosphere will allow us to meet our goals and rapidly ramp-up to full production by the end of 2008."

Although many manufacturing facilities are located in or are moving to China, precision manufacturing is expanding in the U.S., Japan, and Europe.

The 1,000 solar panels will adorn the football-sized roof of the Paul VI audience hall, one of the top energy guzzlers in the sovereign city state. The solar system will be able to provide all the heating, cooling, and lighting needs of the entire building year-round, and any extra electricity generated will be fed back into the Vatican’s grid.

Pier Carlo Cuscianna, head of the Vatican’s department of technical services and mastermind of the project, was inspired by the calls of Pope Benedict XVI and Pope John Paul II to treat the planet with respect and their warnings that global warming will effect the world’s poorest and most vulnerable people.

This isn’t the first time the Vatican has shown leadership on clean energy. In 1999, the entire lighting system of St. Peter’s Basilica was refurbished with energy-efficient lighting, which cut its energy consumption by about 40 percent.

Although Vatican City is not a signatory of the Kyoto Protocol, the Catholic News Service reports that this solar project marks “a major move” to reduce its carbon-footprint and move away from its dependence on Italy’s power grid.

OptiSolar Farms of Canada, a subsidiary of California-based Opticsolar, Inc. was awarded the 20-year contract. The Ontario Power Authority will purchase the solar energy for 42 cent per kilowatt hour, a premium price that contributed to OptiSolar choosing Ontario for the massive project over its home base of California.

The company wouldn’t talk about the cost of the project for proprietary reasons, but they claim to have developed a way of mass-producing solar cells to dramatically lower the cost of the technology. Solar still isn’t cheap: some estimates put the cost of the plant at around $300 million. But you’ve got to start somewhere, and Ontario’s provincial government wants to make solar – typically a low-maintenance technology - a common energy source. From the Toronto Star:

“Deborah Doncaster, executive director of the Ontario Sustainable Energy Association, said the premium may seem high but is justified given the environmental benefits. She said it's often forgotten that solar-generated electricity tends to offset natural gas during peak periods when air conditioners are blasting and electricity rates are at their highest.”

This is a big solar step for Canada. The Sarnia project is 400 times larger than the country’s next biggest solar system. But even this project won’t be the world’s largest for long: Germany is planning a similar sized plant, and Australia announced funding for a proposed 154 MW solar plant to be online by 2013.

The $1.5 million United Nations-backed project aims to increase the number of homes using solar power in the Karnataka state of southern India. The number of homes using solar power has risen from 1,400 just four years ago to 18,000 today. Indian banks have also helped out by financing the solar systems, which can cost $300-$500 in an area where annual family income is $1,200. The UN’s involvement cut initial interest rate payments, but will be phased out over time.

A UN report to be released this week at the UN Commission for Sustainable Development shows that the solar power is cheaper and healthier than using the common kerosene lamp (no fumes to inhale or dim light to strain the eyes), and it doesn’t emit global warming pollution.

The solar systems allow for a few hours of power to run light bulbs, a radio, fan, or television. But that's enough to make a big difference, according to a UN statement:

“[The lighting] has been credited with better grades for schoolchildren, better productivity for cottage-based industries such as needlework artisans, and even better sales at fruit stands, where produce is no longer spoiled by fumes from kerosene lamps.”

Because of the project's success and its affordability, plans are in the works to expand the model to other developing nations. Efforts are underway in Tunisia, and future projects are planned for China, Indonesia, Egypt, Mexico, Ghana, Morocco, and Algeria.

The Air Force expects to save around $1 million each year from lower electric bills. The $100 million projected capital cost is being funded by private investors, with the Air Force paying none of the construction costs. The investors project a steady flow of revenue from the Air Force’s purchase of the electricity and substantial federal tax subsidies.

Despite the high costs of solar, Nellis Air Force Base sees a real value of relying on clean, renewable energy. Major Don Ohlemacher, operations flight chief and acting commander of the 99th civil engineer squadron at Nellis:

“It allows the Air Force to show its leadership in applying renewable energy and new technology to reduce our needs to use traditional forms of electric power.”

Others are also positive about solar power, but point out that there are other renewable energy technologies as well. Paula Mints, associate director and photovoltaic specialist with Navigant Consulting:

“The industry has some problems to solve. A lot of people are focusing on these large fields as a way to bring down the price of solar…They certainly have their place in the energy portfolio, but there are a lot of other technologies out there."

The plant will not have a battery to store the energy and will serve as a supplemental rather than a primary generating source.

The new design features many nano-towers - think of microscopic blades of grass - that capture more sunlight because they have a larger surface area than the traditional flat design of photovoltaic (PV) cells. These three-dimensional panels produce about 60 times more current that regular solar cells. Because of this leap in efficiency, the coatings on the PV cells can be made thinner, and the overall size, weight, and mechanical complexity of the systems are reduced. From the news release:

“The GTRI photovoltaic cells trap light between their tower structures, which are about 100 microns tall, 40 microns by 40 microns square, 10 microns apart — and built from arrays containing millions of vertically-aligned carbon nanotubes. Conventional flat solar cells reflect a significant portion of the light that strikes them, reducing the amount of energy they absorb.

Because the tower structures can trap and absorb light received from many different angles, the new cells remain efficient even when the sun is not directly overhead.”

But although the new design can produce a current much more efficiently, photovoltaic cells have to generate a voltage too. So far there’s too much resistance within the solar cell to produce the type of electricity that’s needed. Researchers say that hurdle will be the next phase of development.

The United States Air Force funded part of the research, seeking a smaller, more efficient solar panel that could eventually be used to power satellites and spacecraft. Researchers at Georgia Tech believe solar power would see a large jump in residential and commercial use as well if this lightweight and more efficient design is proven effective.

Sign seen in front of Al Gore's mansion in the posh Belle Meade section of Nashville Thursday, indicating Gore is moving forward with plans for solar panels to help power his mansion. Here's a link to the the Belle Meade Board of Zoning Appeals meeting agenda - there are no details on the size of the solar panels, how much power they'll generate, or whether or not they'll be tied into the grid via a "net metering" arrangement so Gore can sell excess power to the grid through a "net metering" arrangement.

Tennessee is not a mandatory "net metering" state, though the local electric utility that serves Gore's house does offer the option for customers who generate their own power. But Nashville Electric Service does offer the Tennessee Valley Authority's "Generation Partners" program, which purchases customer-generated power from solar panels or wind turbines at a rate of 15 cents per kilowatt hour.

No word on whether Gore himself will be at the zoning board meeting to make the case for why he should be allowed to put solar panels on his house.

I've given Gore a lot of well-deserved grief - on this blog over his use of "carbon offsets" to present himself as "carbon neutral" even as he continues to consume large quantities of carbon-based energy, but he deserves praise for trying now to "walk the walk" and live the way he has long urged others to live in terms of using clean, renewable energy.

I spoke with Gary by phone on April 5th.

Green Options: Why did you decide to cut your energy use in half?

Gary Reysa: I’m very concerned about global warming, and now that that I have a new grandchild, I see the impact it could have on future generations. It’s easy to get the feeling that there’s not much an individual can do, so my wife and I thought: What can we do? Could we make a significant cut in our energy use and global warming emissions? Could we cut it in half?

GO: How did you begin?

GR: The Half Plan seemed really ambitious to us at first. For one thing, we had no access to special technology. But I had begun some projects back around 2000 when we moved into our house and I started keeping track of our energy bills. When we officially began the Half Plan, we decided to do the projects that offered the most energy saving per dollar spent for our climate, house, skills, and habits.

GO: Wouldn’t it have been a lot easier to just buy carbon offsets?

GR: I have mixed feelings about carbon offsets. I wouldn’t criticize anyone for doing it, but it’s just not for me. I do believe there are a lot of places in the world where you can spend a few bucks and get carbon reductions. But I feel like some people use them to get out of doing real action.

I feel better about doing something directly that reduces my carbon footprint. But even with the Half Plan, we still have to buy green power from Northwest Energy to make up for what we use. We’re not completely independent of the power grid.

GO: You said you didn’t have access to any special technology for cutting your energy use. Did that affect the execution of your plan?

GR: Not at all – once we started researching it, we found out that almost all the equipment we needed was actually available locally.

We did a lot of different projects to cut our energy in half. We bought a Toyota Prius, installed a solar water heater, energy-efficient light bulbs, better insulation in our attic, sealed up the windows, put our computers on power strips (shutting off the power strips stops the computer from continuing to “sip” electricity, even when it’s supposedly off) and installed dryer venting. And those are just a few of the projects.

GO: Has the Half Plan been very expensive?

GR: So far we’ve spent $8800. The single biggest expense has been the Toyota Prius - but it’s also been the single biggest energy savings and biggest cut to our global warming emissions. It cut our transportation energy use by about 60 percent! We thought we’d be making a sacrifice by buying a smaller car, but it’s been great and we use it for 85 percent of our driving. We do live in the snowy mountains, so we need bigger car with 4-wheel drive part of the time.

I factored in a $4000 cost for the Prius into the overall $8800 cost of the Half Plan, because $4000 is the premium we paid for the hybrid features. We were due to replace our old Outback vehicle anyway (it had 205,000 miles on it), so the decision was whether to buy a conventional or a hybrid car.

Our other big expenses included the solar projects. In fact, I just finished another big solar project, but I haven’t factored that into the cost yet. It's a solar space heating project that uses solar water heating collectors to provide space heating for the house. The collectors are on the south wall of our new garden shed. They heat water in a 500 gallon tank behind the shed which gets pumped to the house.

Solar collectors for space heating

GO: Have the savings outweighed the initial investments?

GR: The savings has been phenomenal. We’ve invested $8800 and I’ve calculated that we’ll save $4600 in energy costs and 20 tons in global warming pollution each year. The cost savings will continue to go up as electricity and fuel prices go up.

One really neat project has been making our computer use more energy efficient. Our two computers and related equipment use about 270 watts of power when turned on. We put all of it on power strips. At night, we hibernate the computers and then turn everything off with the power strip switch. During the day we have the computers set to hibernate if they are inactive for 15 minutes.

This saves a total of 1624 kilowatt hours of electricity per year, 3200 lbs of global warming emissions, and $162 per year! This just knocked me out.

GO: What was the Half Plan’s biggest surprise?

GR: The biggest surprise was that there were no surprises. It was pretty painless except for the money invested into the projects, but we’ve already earned a big chunk of it back in our first year of savings.

It was relatively easy to do these projects, too. We live pretty normally – as in we waste a lot of energy! – but we started paying more attention to how we use our energy. To me, it would be fall-off-the-log-easy for people to do this without sacrificing or paying much. It’s just a lack of focus that keeps it from happening.

GO: Now that you’ve found the Half Plan so easy to do, have you thought about cutting your energy even further?

GR: We plan to cut it in half again. This time we will have to use solar PV panels for our electricity, which has a higher cost and a slower return than our other projects. But I’m not doing this next phase for the financial return; I’m doing it to cut my carbon dioxide pollution that causes global warming.

GO: So the next half may not be so easy?

GR: We did the Half Plan without changing our lifestyle at all. But to cut our energy further, we’re going to have to make changes like drive less or bike more. That’s not a downfall for us, it just requires more work. There will certainly be lifestyle changes this time.

For example, we just got back from Hawaii. I felt guilty for spending 2500 lbs of CO2 to go! But I think if we’re going to get serious about making another 50 percent drop, then we will need to start thinking harder about trips like that.

GO: So how do you entertain yourself out in Big Sky country?

GR: I love the TV show Living with Ed. It's a reality show with Ed Begley Jr and it's about how he lives his green lifestyle with his wife in Studio City, CA. It makes technical sense, it’s very entertaining, and he really cares about the issue and lives his life accordingly.

For a good read, I’d recommend The Carbon Buster's Home Energy Handbook by Godo Stoyke. It gives a long list of projects that people can do to cut their CO2 emissions and save money. It details the equipment needed, cost, return, energy saving, and carbon saving. I like the book so much I bought a second copy for our local library.

GO: Your website is a fantastic resource; very easy-to-understand information, graphs, and calculations. Any specific tips on how folks can get started on the Half Plan?

GR: At my website, Build It Solar, I have a Half Plan for People Who Like Plans and a Half Plan for People Who Don’t Like Plans, so folks can choose what works best for them.

I’m an engineer, and I know that simplicity is everything. When you have trouble with a design, it’s almost always because it’s too complex. For example, I found that the solar thermal designs are really simple and that anyone should be able to build it.

The other thing folks have to realize is that we are the problem. When you get mad about global warming, you have to look at yourself in the mirror. I read stuff on the Internet and I get the feeling that people are pointing fingers but aren’t identifying the problem as themselves. Instead, they want a quick fix or someone else to come along with the technology that will allow us to not have to do anything. And they feel comfortable about the fact that they’re not doing anything.

We’re the ones generating this problem, but that also makes it easy for us to do something about it. We’re in the driver’s seat to make drastic reductions. It’s easy to do. For example, efficiency is something you can implement quickly, and we can get a significant drop in emissions right away and painlessly. If enough people do that, we’ll have really made a difference.

GO: Do you think this can all really make an impact?

GR: My actual CO2 reduction is about 20 tons each year. If 100 million families did the same thing, the energy we would save we be about 25 percent of all of the U.S. CO2 emissions. That's huge! And the best part is that we know this can be done – with no help from new technology or George Bush. We can do this ourselves, right away.

Last week, the planet’s most powerful solar energy system was inaugurated in Serpa, Portugal, about 125 miles southeast of Lisbon. Covering approximately 150 acres, the solar farm is already making electricity for 8,000 homes in one of the poorest areas of the country.

The solar system was built by California-based PowerLight and financed and owned by GE Energy Financial Services. Todd Woody of the Green Wombat blog was at the dedication ceremony:

“The reception given PowerLight and GE shows why countries like Portgual, Spain and Germany have become attractive markets for solar power plants. Unlike the United States’ complex and undependable system of state and federal tax credits for solar power, Portugal supports renewable energy with a simple “feed-in tariff” that will pay GE a premium rate for 15 years for the electricity produced by the $75 million Serpa power plant. Portugal modeled its policy on Spain’s, were PowerLight is building two 20-megawatt range power stations.”

Although a new solar plant in Germany has the capacity to produce more power, experts believe that the technology and good solar resources in Portugal will allow the Serpa plant’s 52,000 panels to actually produce more electricity than any other plant in the world.

Portugal’s global warming emissions have surged 37 percent since 1990, one of the largest increases of any nation. Besides being a source of clean, renewable energy, the USD $75 million solar plant is expected to spur more alternative energy development in the region. It will also help Portugal take a step towards its rather astonishing goal of getting 45 percent of its energy from renewable sources by 2010.

So how does he produce zero emissions?

On a sunny day, Strizki can get more than enough of his electricity from the solar panels. The excess goes to an electrolyzer that then breaks down a tank of water into oxygen and hydrogen. The oxygen is released into the atmosphere, but the hydrogen is stored in 10 1,000-gallon propane tanks. So when the solar panels aren’t producing enough energy, the hydrogen is piped to an air-conditioner-sized fuel cell that makes electricity.
The fuel-cell car in the garage is called “The New Jersey Genesis” and Strizki – a civil engineer – helped design the car and maintains it for the NJ Department of Transportation. He fills it up with the hydrogen made from his electrolyzer.

This sort of system isn’t going to be available commercially for the rest of us anytime soon. Strizki’s project is extremely expensive - $500,000, paid for in part with a $250,000 grant from the NJ Board of Public Utilities.

Strizki acknowledges that the enormous cost is a huge hurdle, but believes that, with mass production, the price of the system (not including solar panels) would be about $50,000 and the new solar system would be around $80,000 (some states like NJ offer rebates that cover up to 70 percent of the solar’s cost).

Then there’s the question of efficiency. Critics point out that electrolyzers are only 50 percent efficient. By the time the process is complete, the hydrogen that is converted back into electricity is only half of the energy with which the process started. Sending that power back to the grid, some say, would be more effective because it would displace other dirty energy sources.

Strizki has created a company called Renewable Energy International that engineers, installs, and supports renewable energy systems like his. Despite its costs and efficiency questions, he still believes that hydrogen is the best solution to our clean energy problems. “No one has said what I’m doing doesn’t work…Nothing is as wildly expensive as destroying the whole planet.”
