Global Market for E-Scooters
and E-Motorcycles to Surge, Report Says
The global market for electric motorcycles and scooters is expected to surge
, with the number of vehicles projected to jump from 17 million in 2011 to more than 138 million by 2017, according to a new report. The two-wheel electric vehicles, which are already popular across Asia, will become increasingly common elsewhere as the rising cost of petroleum-based fuels and government incentives will drive market growth, according to the report by Pike Research. “They are relatively low cost to own, do not take a lot of space, and are easy to maintain, therefore making them attractive for city dwellers,” said Dave Hurst, a senior analyst for the Colorado-based clean-technology research firm. While the market for electric scooters will be six times greater than electric motorcycles in most markets, e-motorcycles are expected to be the more popular choice in some parts of the world, including North America, because of their higher speed and greater range. According to the analysis, the growth of electric vehicles will spur an increased demand for batteries, with the market for lithium ion batteries for e-motorcycles expected to grow at a compound annual rate of 24 percent from 2011 to 2017, and the market for lithium ion batteries for e-scooters predicted to increase at 19 percent.

Effects of Poverty, Pollution To Be Researched in Long-term EPA Study
The U.S. government will award $7 million in grants for research into the cumulative health effects of environmental pollution and social factors
such as stress and poor nutrition in low-income communities. While the U.S. Environmental Protection Agency (EPA) typically limits its research to the effects of individual pollutants and chemicals, this initiative
will target neighborhoods that are exposed to multiple factors that scientists say can amplify the effects of toxic pollutants. The grants will support research into the combined effects of metals and stress on the central nervous system; disparities in air pollution risks; the effects of stress and traffic pollution on childhood asthma; and the reasons that some ethnic groups are more susceptible to environmental health risks. “This research could pave the way for more interdisciplinary work that is responsive to community concerns and environmental justice,” said Paul Anastas, assistant administrator for the EPA’s Office of Research and Development.

Study Evaluates Markets
For High-Speed Rail Systems in the U.S.
A new study identifies the high-speed rail corridors in the U.S. with the greatest potential
to attract ridership in the nation’s so-called “megaregions.” The study by the group America 2050 scores 7,870 potential rail
corridors using 12 critical factors, including population, employment concentrations, rail transit accessibility, and air travel markets. In addition to obvious potential markets such as New York to Washington and Los Angeles to San Diego, the study cites other megaregions with the potential to have well-developed high speed rail systems, including Chicago to Milwaukee and Dallas to Houston. The study encourages the federal government to conduct a similar evaluation to decide where investment in high speed rail systems should be concentrated. The study only considered rail lines that extend from 100 to 600 miles, a distance at which trains can compete with automobiles and aviation.

Digital Billboards Consume
Large Amounts of Energy, Analysis Shows
The growing number of digital billboards on U.S. roads and highways consume large amounts of energy
and are creating a wide variety of electronic waste, according to a new report. The new study says the typical digital billboard consumes about 30 times as much energy as the average American household. The digital billboards use more efficient LED (Light Emitting Diode) lighting than traditional signs, but deploy so many of the LED bulbs on each billboard that energy use is high; traditional billboards use just one or two large bulbs to illuminate signs, according to the study
by Gregory Young, a Philadelphia-based urban planner. In addition, digital billboards are illuminated day and night, and require cooling systems that use more energy. And while LEDs, plasma and LCD screens are recyclable, reuse is not mandated, leading to a large surplus of “techno-waste,” said the study, published by the group Scenic America. The U.S. has roughly 800 digital billboards, compared with 450,000 traditional billboards. But use of the technology is expanding quickly, with more than 2,000 expected by 2012.

London’s New Black Cabs
Must Be Electric by 2020, Mayor Says
In a push to improve air quality in London, city officials will require that all new black taxi cabs be electric by 2020
. Under increased pressure to reduce the worst air pollution in Europe, London Mayor Boris Johnson says the city will refuse licenses
to any taxi older than 15 years beginning in 2012, a move that will remove about 1,200 black cabs from London’s roads. Beginning in 2013, the city will require that cabs undergo two emissions inspections annually. In Central London, vehicles account for about 80 percent of air pollution, with black cabs contributing about 20 percent of the emissions. The new policy in London comes as officials announced plans to install 4,000 new electric vehicle charging stations throughout the UK
, calling 2011 the “year of the electric car.”

Creating ‘Living’ Buildings
With Materials That Pull CO2 from Air
A new field, known as “ethical synthetic biology,” aims to combine chemistry, architecture, and climate science to construct buildings out of materials that extract CO2 from the atmosphere and convert the carbon into structural material
. For example, scientists at the University of Greenwich are exploring the possibility of using “protocells” — essentially bubbles of oil in watery fluids that are highly sensitive to light or chemicals — that pull carbon from the atmosphere to create a coral-like skin that would protect buildings. Neil Spiller, an architect and head of Greenwich's School of Architecture & Construction, said such protocells could possibly be used to create a limestone-like material that would petrify the pilings now supporting many of Venice’s buildings, slowing the city’s slide into the sea. At the University of Southern Denmark, researchers have succeeded in capturing carbon dioxide in solution and converting it into carbon-containing materials.“We want to use ethical synthetic biology to create large-scale, real world applications for buildings,” said Spiller.

China Makes Green Cars
A Priority in Latest Five-Year Plan
The Chinese auto industry will make development and production of electric and hybrid vehicles its top priority
over the next five years, according to its latest Five-year Plan. By 2015, China aims to sell 1 million “new-energy” automobiles, according to a report in People’s Daily
. China’s Ministry of Industry and Information Technology has already announced that the government will invest more than 100 billion yuan ($14.5 billion) over the next decade to make China the world leader in green car production. Meanwhile, in the UK, where a government subsidy next year will shave £5,000 ($7,960) off the cost of new electric cars, a company predicts that the next generation of green cars could be charged wirelessly
with the same technology that charges electric toothbrushes. The company, HaloIPT, this week demonstrated how electric cars can be charged wirelessly by parking over a transmitter pad, and predicted that one day vehicles might be able to re-charge by using roads outfitted with electrical systems that charge cars as they travel.

Starbucks In Trial Study
To Begin Recycling Its Coffee Cups
Starbucks is testing a new recycling program
at its 86 locations in New York City, a nine-week trial that company officials hope will eventually lead to the recycling of the 3 billion cups used by the chain
annually in the U.S. The company has added separate recycling bins just for cups — and not other recyclables — that are then picked up by the same hauling company that collects the company’s cardboard recyclables each night. By including the cup pickup in the existing loads, the company will not have to add new truck routes, said Jim Hanna, Starbucks’ director of environmental impact. The cups will be sent to a paper mill, where they will be converted into pulp used for paper towels and other products. During the trial, the company will test whether recycling the cups is profitable for the paper mill and whether the cups can be collected separately without customers tossing other trash into the cup recycling bin.

U.S. Home Energy Use
As High as in 1970s, Despite Advances
The average American household uses the same amount of energy it did in the early 1970s
, despite significant improvements in the efficiency of household appliances, according to a report in the Washington Post
. Even though appliances such as dishwashers and refrigerators now use half the amount of energy that they did several decades ago, average household energy use has remained the same because houses have been getting bigger and because they now contain more power-hungry devices, such as computers, flat-screen televisions, video games, and digital video recorders. One sign of that growing demand from computers, TVs, and other gadgets is that while electricity accounted for 23 percent of an average household’s energy use in 1978, it now accounts for 42 percent, according to the Post
. Even though household energy use has essentially remained flat for the past 40 years, the number of households has increased significantly as the U.S. population has grown from 203 million in 1970 to nearly 310 million today, pushing up overall energy use.

Study Projects 4.7 Million
Electric Vehicle Charging Stations by 2015
As increasing numbers of electric vehicles enter the global market over the next few years, more than 4.7 million charging stations will be accessible worldwide by 2015
, with nearly 1 million of the those expected
in the U.S., according to a new study. Of the 974,000 charging stations predicted in the U.S., about 64 percent will be charging units in residences, according to Pike Research
. Across Asia and Europe, where multi-family housing is more common, only about 35 percent of charging stations will be residential, with a greater percentage of consumers relying on public or commercial stations to charge their vehicles, according to the study. In addition, North America will see a higher percentage of plug-in hybrid vehicles, which require less charging infrastructure because they have smaller battery packs and gasoline engines that allow vehicles greater range.

U.S. Government Introduces
Nation’s Largest ‘Zero-Energy’ Building
The U.S. government next month will open what it calls the nation’s largest zero-energy building
, a 222,000-square-foot structure on the campus of the Department of Energy’s National Renewable Energy Laboratory that designers say will consume 50 percent less energy than typical buildings and will generate whatever power is needed on-site. While solar panels will produce energy for the building, a research facility located on the department’s Golden, Colo. campus, the building is also designed to utilize techniques and technologies that employ natural light and the planet’s tendency to heat and cool. The narrow design will allow daylight to enter all work spaces; “smart” sensory technology will alert

New London Tower Will
Generate 8 Percent Of Its Own Electricity
A new 42-floor London skyscraper will be the world's first building to incorporate wind turbines in the design
, an innovation developers say will generate 8 percent of the building’s electricity needs. The Strata Tower, a 408-unit apartment building scheduled to open in July, will be topped with three 19-kilowatt turbines — each with five 29.5-foot blades designed to suck wind from various angles and accelerate it through tubes, generating as much as 50 megawatt-hours of electricity annually. It will also generate about £16,000 to £17,000 annually through the nation’s new feed-in tariff, the developers say. The £13-million tower, which developers hope will be a model in sustainable construction, will also utilize natural ventilation rather

than air conditioning. By 2019, government law will require carbon neutral design for all new buildings. Green building advocates described the Strata design as pioneering, but questioned whether wind turbines would become common in skyscraper projects. “I doubt wind power will become a common feature in high-rise inner-city projects,” said Paul King, chief executive of the UK Green Building Council. “But without this type of bold innovation, how would we ever know?”

‘Eco-bling’ in the U.K.;
CO2-Spewing Lawns in the U.S.
Installing wind turbines or solar panels on homes that are not well-insulated or energy-efficient amounts to little more than “eco-bling” that makes owners feel good but does little to reduce carbon emissions
, according to a study by the U.K.’s Royal Academy of Engineering. To meet the U.K.’s goal of making all new homes and buildings carbon neutral by 2020 and slashing carbon emissions by 80 percent by 2050, the report said, the government should focus on making new buildings highly energy-efficient, retrofitting older buildings to improve their energy efficiency, and investing in large-scale wind and solar projects. The report said that for wind turbines installed on homes to produce sizeable amounts of electricity, the turbines would have to be so large that their vibrations would damage residential structures. Meanwhile, a new study, to be published in the journal Geophysical Research Letters
, had some sobering news for homeowners hoping to reduce their carbon footprints: The study, conducted by scientists at the University of California, Irvine, said that the fertilization, mowing, and leaf-blowing of lawns produces four times as many greenhouse gases as the lawns themselves absorb

Food Recycling Program
A Major Success in San Francisco
San Francisco’s new food recycling program — the first in the U.S. that requires all food waste from homes, apartments, businesses, and restaurants to be recycled and composted — has been enthusiastically embraced by city residents
, officials say. Although the program was officially launched on Wednesday, city officials say residents have been recycling food for weeks and are already setting aside about half of the city’s 500 tons of daily food waste. The city requires residents and businesses to place food scraps in sealed buckets, and then collects the buckets and trucks them to San Francisco’s Organics Annex, where the food waste is composted. The compost is sold as fertilizer to area farms and vineyards. Seattle was the first U.S. city to require all households to recycle food waste, but San Francisco’s law covers businesses and apartments. Jared Blumenthal, the city’s environmental officer, said residents have strongly backed the food recycling plan because — overwhelmed by bad environmental news — this gives them something concrete to do. “This is not rocket science,” he said. “This is putting some food scraps into a different pile and turning them into compost.”

New Bus Systems Reduce
Traffic, Pollution in Developing Cities
Large, low-emission buses being introduced in developing cities from Mexico City to Ahmedabad, India are reducing congestion on crowded roadways and cutting pollution and carbon dioxide emissions
, all at a much lower cost than constructing subways. In Bogota, Colombia, city leaders took control of two to four center lanes of major boulevards for the TransMilenio rapid transit system. Small walls isolate the “tracks” of the bus lines from other traffic, and passengers are able to board the long, segmented buses from the center platforms of modern stations. Since 2001, the TransMilenio bus system has allowed the city to remove 7,000 small private buses from roadways and has slashed fuel use by more than 59 percent, according to a New York Times
report. As a result, TransMilenio last year became the only large transportation system allowed by the United Nations to generate and sell carbon credits. Climate researchers say that emissions reductions related to transportation will become increasingly urgent in coming decades, particularly in the developing world. Projects similar to Bogota’s TransMilenio are planned in Cape Town, Mexico City, and Jakarta, Indonesia.

Obama Unveils Major Spending
For High-Speed Rail Network in the U.S.
President Obama has proposed spending $13 billion as a “first step” toward building a series of high-speed rail lines connecting major metropolitan areas in the United States
. Among other places, the proposed lines — which would ultimately cost hundreds of billions to construct — would run from Washington to Boston; San Diego to San Francisco; Chicago to Minneapolis; Kansas City to Louisville, Ky.; Eugene, Ore. to Seattle, Wash.; Miami to Tampa, Fla.; and San Antonio, Texas to Tulsa, Okla. Obama said that $8 billion for the rail lines will come from his economic stimulus plan with another $5 billion to be allocated in the next several years. “High-speed rail is long overdue, and this plan lets American travelers know that they are not doomed to a future of long lines at the airports or jammed cars on the highways,” Obama said. California Gov. Arnold Schwarzenegger said his state hoped to receive a “significant portion” of the federal funds to help build a proposed $30 billion “bullet train” that would whisk travelers from Los Angeles to San Francisco in 2 hours.

First Solar-Powered City in U.S.
Florida Power & Light and a real estate developer have announced that they will build the first solar-powered city in the U.S., a community of 19,500 homes, offices, retail shops, and light industry whose electricity will come from the world’s largest solar photovoltaic plant.
The $300 million, 75-megawatt plant will provide enough electricity to power the proposed community — Babcock Ranch — and to export electricity to other parts of Florida, according to Florida Power & Light. The community, located near Ft. Myers, is being developed by a former National Football League player-turned-developer, Syd Kitson, who says half of the 91,000-acre town will remain undeveloped green space. Kitson said the community will be a model of sustainability that features a smart power grid, recharging stations for electric vehicles, and homes built with the latest in energy-efficient technologies. Construction on the power plant and development is scheduled to begin next year; utility company officials say their solar plant will be built regardless of the status of the planned city.

Urban Residents Generate
Lower CO2 Emissions Than Suburbanites
People who live in large cities generate significantly lower greenhouse gas emissions
than those who live in rural and suburban areas, according to a report by the International Institute for Environment and Development. While the high concentration of population and businesses found in cities are often seen as a pollution “problem,” researchers found that “high densities and large population concentrations can also bring a variety of advantages for … environmental management.” For instance, while New York City emitted 58.3 million tons of carbon dioxide in 2005, the per capita average of 7.1 tons was about a third of the U.S. average of 23.92 tons per capita in 2004, according to the study. The density of buildings and high use of public transportation in New York contributes to the lower individual emissions, the report stated. Likewise, the 2006 per capita emissions average in London was about 6.18 tons – about 55 percent of the UK’s 2004 average of 11.19 tons. The report examined emissions data from cities worldwide. “The real climate change culprits are not the cities themselves but the high consumption lifestyles of people living across these wealthy countries,” said report author David Dodman.

Amsterdam Makes a Bid
To Become Leader in Energy Efficiency
Amsterdam will invest more than $1 billion over the next three years to become one of Europe’s leading “smart cities”
by installing sophisticated energy monitoring technology in households and funding other energy efficiency programs. BusinessWeek
magazine reports that city officials aim to install “smart grid” technology — which allows consumers to monitor energy usage in real-time and carefully control the operations of heating systems and appliances — in 200,000 homes and apartments. Such technology has enabled consumers to slash energy usage by as much as 50 percent, and Amsterdam officials plan to eventually install it in the city’s more than 600,000 households. The “smart city” program also will provide financing for roof insulation and energy-efficient lighting, will underwrite the purchase of electric garbage trucks, and will power electronic displays at bus stops with solar panels, among other measures. Accenture Consulting, which is working on the Amsterdam energy plan, is also collaborating with utilities around the world, including a program to install smart-grid technology in 60,000 Denver households this year.

Germany Builds Houses
That Use Almost No Energy to Heat
Architects in Germany and other countries are designing “passive houses” that have extra-thick insulation and special windows and doors
so almost no heat escapes and almost no cold seeps in.
A "passive house"
in Darmstadt, Germany
This design allows the homes to be warmed not just by the sun, but also by the heat from appliances and from residents’ bodies. So far, the New York Times
reports, an estimated 15,000 passive houses have been built worldwide, most of them in Germany and Scandinavia. Earlier attempts at building sealed solar-heated homes failed because of stagnant air and mold. But passive houses use a central ventilation system that allows warm air going out to pass alongside clean, cold air coming in, allowing heat to be exchanged with 90 percent efficiency. “The myth before was that to be warm you had to have heating,” says Wolfgang Hasper, an engineer at the Passivhaus Institut near Frankfurt. “Our goal is to create a warm house without energy demand.”

Bicycle Sharing Programs Enjoying Widespread Success in Europe
Bicycle-sharing programs that allow riders to pick up a bike in one city location and ride it to another are growing rapidly in Europe t
hanks to new technology to keep track of the bikes and increasing environmental awareness. The New York Times
reports that cities such as Barcelona, Paris, Lyon, Pamplona, Rome, Dusseldorf, and Rennes, France have all become sites of successful bike-sharing programs. In Barcelona, a program called “Bicing” offers riders 6,000 bicycles at 375 stands throughout the city. Technology is key, as riders use electronic cards to rent bikes parked at mechanized docks, with the cost of the ride — often as cheap as 30 cents per hour — being deducted from their bank accounts. The bikes in Barcelona are often being rented 10 times a day and demand cannot keep pace with supply. Paris’ Velib’ program, with 20,000 bikes, has been an enormous success. The bike-sharing boom in Europe is prompting other cities, including Shanghai, to launch their own pilot programs.

New York Mayor Calls for Six-Cent Fee on All Plastic Bags
New York Mayor Michael Bloomberg has proposed a six-cent fee for all plastic shopping bags used in the city’s shops, delis and grocery stores, a so-called plastic bag tax
that could make the city greener and generate about $16 million a year, according to city officials. It would also make New York the first U.S. city to assess such a fee on plastic, although similar fees are common in Europe. A stiff 33-cent tax in Ireland, for example, prompted a 94 percent drop in plastic bag use within one year, according to the New York Times
. In New York, consumers would be charged 6 cents per plastic bag at the point of sale, with a penny going to the store owner as incentive for compliance, according to the Bloomberg administration. The proposal was praised by environmentalists. “It’s simple, it’s streamlined, it advances environmental objectives and it generates some funds,” said Eric A. Goldstein, a senior lawyer with the National Resources Defense Council. A similar tax will go before voters in Seattle next year.

Mexico Eyes Rooftop Revolution
Mexico City officials want to install a carpet of green gardens on rooftops across the city, a plan they hope will reduce air pollution in a city with a notorious smog problem and little room for new ground-level gardens. Mayor Marcelo Ebrard hopes to add more than 500,000 square feet
of green roofs by 2012, starting with city buildings. Leaders say the green roofs, which are part of the city’s larger $5.5 billion Green Plan, would reduce energy use for heating the buildings and also help absorb and filter the city’s air pollution. “It’s hard to increase green spaces in a city like this because there’s really no more green space,” said Tanya Muller, the city’s director of urban reforestation. “But almost all of the buildings in this city can support green roofs.” Mexico City hopes to match the success of Chicago, where more than 517,000 square feet of green roofs had been installed through 2007, according to the industry group Green Roofs.

San Antonio Is First U.S. City
To Convert Human Waste to Methane Gas
San Antonio has signed a contract with a Massachusetts company to collect the methane produced by processing the Texas city’s human waste
and sell it to utility companies to burn and produce electricity. Although some U.S. communities have collected smaller amounts of methane from sewage to power waste treatment plants, this is the first time that an American city will be collecting gases from human waste on a large scale to sell to utilities. Under the new plan, more than 90 percent of the human waste flushed down San Antonio’s toilets will be recycled. The city will use the liquid for irrigation, the solids to produce compost, and the gases for energy generation. Sewage gases are similar to natural gas, which is primarily composed of methane.

London Mayor Proposes
Plan for Dealing with Global Warming
London needs to plant more trees, use less water, slash carbon emissions, and improve drainage to prevent and cope with climate change, Mayor Boris Johnson said. With 15 percent of the city at high risk of flooding, Johnson announced a climate-crisis plan
that includes planting trees to soak up carbon and excess rainwater while also cooling the overheated city. Overhauling the Victorian drainage system is also a priority. Even as warmer, wetter winters pose a flood risk, London — which has less water per capita than Morocco — is facing more summer heat waves and droughts. Johnson's plan, claimed as a first for a major world city, calls for reducing water consumption through metering, efficient building construction, and more harvesting of rainwater. His plan furthers ex-Mayor Ken Livingstone’s goal of cutting carbon by 60 percent by 2025.

New York City
Rapidly Switching to Hybrid Taxis
Mayor Michael Bloomberg said the city would start adding 300 new hybrid vehicles to its taxi fleet every month

Ten percent of New York’s 13,150-vehicle taxi fleet already consists of hybrid cars, and the city is on schedule to meet its goal of converting the entire fleet to hybrid technology by 2012. Bloomberg said the Nissan Motor Co. has agreed to sell 200 hybrid Altimas to taxi operators every month, and Ford and Chevrolet will each supply 50 hybrid vehicles. Hybrid taxis get 25 to 30 miles per gallon in the city, twice the mileage of non-hybrid taxis. The chairman of the city’s Taxi and Limousine Commission said that switching to hybrids will save the average taxi driver about $6,500 a year in fuel costs. Bloomberg, whose hybrid taxi project is just one of 127 green initiatives he is proposing, has touted the reduction in air pollution and greenhouse gas emissions.

Plans for British “Eco-towns”
Are Far From Green, Protesters Say
Demonstrators in England protested against government plans to build 15 new “eco-towns,” contending that the new towns were “the least sustainable way” of building new housing
. According to the critics, the eco-town sites, chosen by developers, risk becoming car-dependent because of their distance from town centers and are in areas currently given over to green space. Most proposals also go against local agreements about development, say representatives of the Campaign to Protect Rural England. According to CPRE, one or two of the planned eco-towns are “truly exemplary” in terms of placement and should be used as templates for the rest. Ten of the sites will be finalized this year, with five eco-towns to be built by 2016 and the rest by 2020.
