     A
    B
Vauban
We know cars are terrible polluters, but would you give yours up? Vauban, a community in southwestern Germany, did just that, and its 5,000 citizens are doing fine. Most streets are free of vehicles, and there are generous green spaces and good public-transport links, including fast buses and bicycle paths.  When people must drive, they can turn to car-sharing clubs.  “All the citizens had the chance to plan their own city,” says Andreas Delleke, an energy expert, “and it's just how we wanted it to be.”
Denmark
During the period of gas shortage in the early 70s, Denmark decided to become self-sufficient ( 自足). So they began a few projects making smart investments along the way.
On the island of Samsoe, local families, fishermen and farmers bought wind turbines (涡轮机) to produce their own energy. Within seven years these turbines were completely paid for. And can you believe just one of wind turbines produces enough electricity for 600 households?

Trey Parker and Matt Stone
Trey Parker and Matt Stone, creators of South Park, have built a sustainable castle with outer siding and inner flooring of recycled wood, recycled carpeting, high-efficiency boiler systems.
“I think more and more today, people are willing to make a statement about the Earth and how they want to protect it,” Michael Rath, home designer and builder says. "For high-end homes in this valley, this is entirely consistent with what they cost."
P-NUT
Who doesn't love the name P-NUT—short for Personal-Neo Urban Transport? It's Honda's latest attempt to create a tiny footprint for a new urban vehicle.
This little P-NUT is unique. With a central driving position, the car is designed to move in tight settings. The  11-foot micro car will seat three with two rear-seat passengers behind the driver.
“The P-NUT concept explores the packaging and design potential for a vehicle designed for the city lifestyle,” said  Dave Marek, a Honda design Spokesman.

F
Israel Company
Is it possible that annoying rush hour traffic could become a source of renewable energy?
Israel's Technion Institute of Technology claims that if we placed special generators ( 发电机 ) under roads, railways, and runways—we could harvest enough energy to mass-produce electricity. A trial process has been used on a smaller scale, in dance clubs for instance, where the pounding feet of dancers light up the floor.
"We can produce electricity anywhere there is a busy road using energy that normally goes to waste," said Uri Amit, chairman of Israel's Technion Institute  of Technology.
Coffee
Coffee. Some of us can't start our day without it, and we don't mind waiting 10 minutes in line for it.
Here is the most effective tip to make you a superstar in environment protection.
Get a coffee machine for your home or office, or persuade your company into buying one.  (Tell them it will improve productivity. ) Skip the coffee line on the way to work and make something that is better-tasting and much better for your wallet.
Plus, you won't need those plastic cups or carrying cases that just get thrown away. Better yet, use your favorite travel mug.
