Guest Blog: America’s Solar Future: The View from Beijing

Tom Rooney, CEO of SPG Solar, rings the solar gong at the SunTech solar factory in China.

Greetings from Beijing where, from my cafe seat near Tiananmen Square,  plans to expand solar power in the United States look a lot different than from my office in Northern California — where I am the CEO of one of America’s larger solar power companies.

Many of the measures — and half measures — that we read about every day in American papers are things the Germans and Chinese and Spanish and French decided to do 10 years ago.

They are racing. We are walking.

Germany, for example: Hardly a sunny hot spot — but it has more solar installations than any country in the world. 200 times more than England. That is because German citizens have been getting 50 to 75 cents per kilowatt hour for the solar power they sell back to the grid. Spain is similar.

Great Britain and France and Ontario and other places throughout the world recently raised their so-called ‘feed in tariffs’ to  comparable levels.

In Gainesville, Florida, the feed-in tariff is now the highest in the country at 32 cents. All of a sudden there is an explosion of interest in solar in Gainesville.

In California, we get less than 10  cents. And that is more than most places.

In the United States, we limit not just the price but also the amount of solar energy an owner can sell back to the grid. So we wait for the day when all the transmission lines are perfect. When the grid is perfect. When all the energy infrastructure is in place.

Meanwhile, we wait for an energy future that may never come.

If we allowed the price to rise, and removed the limits on how much solar energy a farmer or business owner or school or police station could generate, we would see an explosion in demand for solar and other renewables.  That would reduce our dependence on foreign energy and stimulate domestic manufacturing, as well.

It’s a two-fer.

That is our best chance of creating solar panel manufacturing jobs in the United States. But it is already very late in the game.  Michael Northrop of the Rockefeller Brothers Fund points out the most of the world’s largest renewable energy manufacturing happens outside the United States. He says,  “Not only are we shipping oil dollars to the Middle East, we are watching our solar, wind, and other renewable energy dollars begin flowing to Asia. … The U.S. needs to decide rapidly whether it wants to own this future or pay for it.”

From my seat in Beijing, where I am traveling the country visiting suppliers for my solar power installation company, it looks as if this decision has already been made.

What kinds of home improvements could I do that would make my house healthier and more environmentally friendly?
– Elizabeth Bram

Most homes are not lacking in ways they can be healthier for family and kinder to the environment. For one, indoor air quality is a serious problem affecting millions of homes. Studies show that air within homes can be more seriously polluted than the air outdoors–even in the largest and most industrialized cities.

According to Glenn Haege, a master handyman who hosts a national radio show on home repair, as our homes and apartments have become more energy efficient and airtight, “humidity levels from cooking and breathing tend to increase, causing mold and mildew.” Harmful chemicals, he says, from construction materials, insulation, furniture, carpeting, padding, paints, solvents and household cleaners, drawn by this moist atmosphere, combine to contaminate the indoor air which then stays trapped inside.

The first step in remedying this problem is to test your indoor air. Pure Air and Envirologix, among others, sell inexpensive and easy-to-use indoor-air quality testing kits. Once you get an idea of the contaminants floating around your home, you can get to work replacing the offending sources accordingly. Green superstores such as the Environmental Home Center, Green Building Supply and Oikos offer a wealth of greener and healthier building supplies and materials. Also, BuildingGreen.com offers a free online “GreenSpec” database with detailed listings for over 2,000 environmentally preferable building products.

Materials outside the home can also contribute to health problems. One example is pressure-treated lumber, which contains a form of cyanide to keep pests away. Kids who play on backyard jungle gyms and decks made of such material can develop rashes and skin infections. Cedar wood is a naturally pest-resistant alternative that, while more expensive, is a kinder-gentler option that will stand the test of time.

Other ways to green-up the home include replacing traditional incandescent light bulbs with more energy-efficient compact fluorescents, as well as switching out conventional hot water heaters in favor of solar or on-demand tankless versions. And for saving on water, replacing traditional showerheads and toilets with pressurized low-flow alternatives can save gallons per day while generating cost savings on utility bills. Likewise, capturing rainwater and shower “gray-water” to irrigate the garden is another smart move.

Do-it-yourselfers can find hundreds of websites offering tips on green building and repair. Glenn Haege’s MasterHandyman.com and NaturalHandyMan.com both offer a plethora of articles and links and are good resources if you’re looking to improve your own handy skills while staying true to your green ideals. Two helpful books are: Green Remodeling by David Johnston and Kim Master; and Green Building Materials: A Guide to Product Selection and Specification by Ross Spiegel and Dru Meadows. For less handy homeowners, finding a handyman well versed in green building issues might be a better way to go. The Natural Handyman Network offers a free online search tool that should offer some promising leads.

What do you think of those “waste to energy” plants used by cities to generate power?
– Christine Ramadhin, Queens, NY

Waste-to-energy (WtE) facilities, which generate power by burning trash, have been in widespread operation in the U.S. and Europe since the 1970s and are considered by environmental advocates to be a mixed blessing. On the one hand they get rid of garbage without adding to already-stressed landfills and with the added benefit of contributing electricity to the power grid. On the other hand, they do generate toxic pollution, usually as a result of burning vinyl and plastics.

WtE facilities evolved out of basic incinerator technology that simply burns trash and reduces it to ash and smoke. Waste-to-energy plants instead use the garbage to fire a huge boiler. When the garbage “fuel” is burned, it releases heat that turns water into steam. The high-pressure steam turns the blades of a turbine generator to produce electricity.

In the U.S. and Europe, environmental laws regulate WtE plants, typically requiring them to use various anti-pollution devices to keep both harmful gases and particulate pollution (fine bits of dust, soot and other solid materials) out of the air. However, the particles captured are then mixed with the ash that is removed from the bottom of the waste-to-energy plant’s furnace when it is cleaned. Environmentalists contend that this toxic ash, which can include dangerous heavy metals, may actually present more of an environmental problem than the airborne emissions themselves, as it usually ends up in landfills where it can leak into and contaminate soil and groundwater.

According to Greenpeace International, WtE facilities are also among the largest sources of dioxin emissions in industrialized countries. Dioxin is a by-product of burning polyvinyl chloride (PVC) and other plastics, and has been linked to cancer and other health problems. Greenpeace advocates for phasing out WtE facilities in favor of improving recycling rates that reduce the waste stream in the first place.

Currently about 600 WtE facilities are in operation around the world. According to the National Solid Wastes Management Association, an industry trade group, the United States is home to 98 such plants operating in 29 states. These facilities manage about 13 percent of America’s total trash output. In Canada, where landfill space is more abundant, WtE has failed to catch on, with only a few such facilities across the country. WtE has caught on more so in smaller technologically advanced countries such as Japan, Sweden, Denmark, France and Switzerland, where landfill space is at a premium.

Recent improvements in the energy efficiency and environmental impact of WtE facilities means that the technology promises to play a larger role globally in years to come, especially as crowded developing countries start to jump on the bandwagon.
