The 2010 launch of the “Boris Bike” – London’s cycle hire scheme, was the clearest indication to date that cycling was no longer just for a minority, but a healthy, efficient and sustainable mode of transport that city planners wanted in their armoury.
There are now more than 8,000 Boris Bikes and 550+ docking stations in Central London. And the trend’s not anomalous to London: Wikipedia reports that there are 535 cycle-share schemes in 49 countries, employing more than half a million bikes worldwide. However, the real question is: will cycling actually change the city?

As self-driving cars move from fantasy to reality, what kind of effect will they have on cities? A research and urban prototyping project called Shuffle City investigates, and in the process, becomes a manifesto for a new kind of modern city--one that depends less on traditional public transportation like buses or light rail and more on creating a fleet of continuously moving automated vehicles to serve urban mobility needs. Shuffle City looks at the new possibilities that could arise from cities transitioning to cars without drivers. If cars were put into some constant flow as a public good, and if people didn’t all have their own vehicles, there would be no need for the concrete wastelands and lifeless towers that serve as a parking infrastructure in the urban landscapes of car-centric cities like Phoenix and Los Angeles (Under the current ownership model, the average car spends 21 hours per day parked.) The share of city space ruled by parking lots will shrink, making way for more green space, environmental buffers, workspace, housing, retail, and denser planning for more walkable cities...

A street shouldn't just be about transportation, but also about civic definition and social and commercial interaction.
There is no better place to start using land more efficiently than with our streets, our most plentiful and visible parts of the urban commons. The recent "complete streets" movement has made a terrific contribution to getting our streets right, by insisting that they be designed so as to accommodate all users. Connectivity is hugely important to a sustainable street network to encourage walking and shorten driving trips by making destinations more convenient. The pedestrian experience should be safe and enjoyable, and should be so perceived.
Other design elements to help turn streets into worthy places are: - Sidewalks with real curbs;
- On-street parking ;
- Street trees;
- Storefronts with elements that shelter pedestrians such as awnings, arcades, and colonnades;
- Buildings with windows and "other signs of human occupancy such as porches and balconies" for "eyes on the street";
- Design appropriate to safe motor vehicle speeds.

They only occupy two per cent of the Earth’s land mass, but cities today use a huge amount of the planet’s natural capital, consuming 75 % of global resources and generating 80 % of global greenhouse gas emissions. As the world population grows to 9 billion by 2050, the number of those living in urban areas will swell by 3 billion to 6.3 billion. With demand for energy and resources set to spike on the back of urban population growth, smart cities have emerged as the modern answer to the wave of urbanisation sweeping across the globe.
What defines a smart city? Put simply, smart cities integrate diverse technologies to reduce its environmental impact. Using a more formal definition from a recent report by the United Cities and Local Governments, smart cities use new technologies, innovation and knowledge management to become more liveable, functional, competitive and modern, bringing together six key fields of performance: the economy, mobility, the environment, citizenship, quality of life and management.

It's not just flooding: Plenty of other issues—such as rising sea levels and drought—present pressing problems for these urban areas. Climate change is one of the most serious issues facing the world's cities in the 21st century, but so far policymakers, planners, and scientists have come up with few solutions to prevent—or mitigate—its calamitous effects. While flooding disasters like Hurricanes Katrina and Sandy have brought attention to the dangers posed by stronger storms, there are plenty of other threats—such as rising sea levels—that might be even more pressing. Wildfires and drought have already heavily damaged the American Southwest, while flooding threatens low-lying island nations. Visit the link to find which cities that will soon be in danger.

Green energy is the sustainable provision of energy that meets the needs of the present without compromising the ability of future generations to meet their needs. Green energy includes natural energetic processes that can be harnessed with little pollution. Anaerobic digestion, geothermal power, wind power, small-scale hydropower, solar energy, biomass power, tidal power, wave power, and some forms of nuclear power which are able to "burn" nuclear waste through nuclear transmutation and therefore belong in the "Green Energy" category.
Via Dr. Stefan Gruenwald
The program will pay residents for excess solar power they produce on their roofs, with the aim of generating enough to power 30,000 homes.

Rising in the desert outside of Abu Dhabi, Masdar City will be the world’s most sustainable metropolis with no cars (or skyscrapers) allowed. The development is a project of the Abu Dhabi Future Energy Company and has been largely designed by Foster & Partners.
Solar, wind and geothermal sources will fuel the city – sun-powered desalination plants will provide fresh water for inhabitants, which will in turn be recycled. Practicing what it embodies on multiple levels, this new urban area aims to be the definitive region for developing green energy and researching clean technology.
The Masdar Institute of Science and Technology has already been built and more structures are on the way. By 2025, the target population should be up to 50,000 within the walkable 2.3 square-mile perimeter currently planned for development.

A dense, relatively small country, the Netherlands is well suited to electric vehicles, and the new Fastned scheme could be a "benchmark" for other places.
The distinctive yellow stations are about 100 feet across, and covered in solar panels to power things like lights and cameras. Each station, which is located at an existing gas stop, will have four to eight charging points. If all goes well, they could make vehicle charging as convenient as filling a tank, though drivers will still need to wait 15 to 30 minutes before the task is completed.
Find more details at the article link.
