I’ve posted many times about the German experiment in renewables. They keep charging ahead while we dither. Thanks Tea Party! BusinessWeek: The nuclear industry and its supporters pounced on Merkel’s decision.

The renewable energy revolution is under way. Renewable power generation now accounts for around 50% of all new power generation capacity installed worldwide.
The combination of rapid deployment and high learning rates for technology “has produced a virtuous circle that is leading to significant cost declines and is helping fuel a renewable revolution,” according to a new global study of renewable power generation costs in 2012 produced by IRENA, the International Renewable Energy Agency, which announced it isestablishing its global headquarters in the United Arab Emirates during last week’s Abu Dhabi Sustainability Week.
Additions to global wind power generation capacity totalled 41 gigawatts (GW) in 2011, according to IRENA’s “Renewable Power Generation Costs in 2012: An Overview.” That’s in addition to 30 GW of new solar photovoltaic (PV) electricity generation capacity, 25 GW of hydro power, 6 GW of biomass, 0.5 GW of concentrated solar power (CSP), and 0.1 GW of new geothermal power capacity.

Renewable energy revolution worldwide news, and in Cyprus our renewable energy production in 2012 increased by 24%. We have some fantastic renewable energy companies who can be found on www.ecoiko.eu

If you want a preview of the downtown Vancouver streetscape in 2035, start with a walk down Granville or Georgia Street today. Most of the buildings will still be standing. There will be additions and replacements, but most of the changes that will transform downtown's living, work and retail space will be undetectable from the sidewalk. That includes upgrades to water and energy systems in buildings that in 2012 are models of inefficiency by contemporary standards, let alone future ones. "If you are thinking 2035, realistically 80% of the buildings that will be in existence at that time have already been constructed," said Innes Hood, a professional engineer and senior associate with Stantec Consulting, a consulting firm with 12,000 planners, architects, engineers, project managers and experts, working in teams to break down the boundaries between designers, contractors and investors, while using advanced computer modelling programs. Retrofits are crucial. One of Hood's main assignments is overseeing the redevelopment of existing buildings. More often than not, that means uncovering, through energy audits, glaring examples of waste - air leaks, inadequate insulation, inefficient heating and ventilation systems. "We are involved in residential projects where we can achieve 80-per-cent reduction in energy use and become essentially greenhouse gas neutral through the implementation of cost-effective technologies," Hood said. "We're not having to strive to the leading edge. These are tried and true technologies around good building enclosures and high-performance mechanical systems such as heat pump technology...

"The buzz from Copenhagen is all about its new "superhighway" for bikes. The real secret to its pioneering urban design, though, is that it puts people first on all its streets."

Urban resource consumption and waste disposal is widely seen as the root cause of many of the world’s environmental problems.
Because so much damage has already been done to the world’s ecosystems, and solutions need to be found to reverse it, we need to start thinking of regenerative rather than just sustainable urban development.

What makes a city a “Smart City” as opposed to a city where some “smart things” happen? Three obvious criteria for answering that question stand out: 1. Smart Cities are led from the top – they have a strong and visionary leader championing the Smart agenda across the city. 2. Smart Cities have a stakeholder forum – they have drawn together a community of city stakeholders across the city. Those stakeholders have not only created a compelling vision for a Smart City; they have committed to taking an ongoing role coordinating a programme to deliver it. 3. Smart Cities invest in technology infrastructure – they are deploying the required information and communication technology (ICT) platforms across the city; and doing so in such a way as to support the integration of information and activity across city systems.
It’s also important, though, to consider what is different about the structure and organisation of city systems in a Smart City. How does a city decide which technology infrastructures are required? Which organizations will make use of them, and how? How can they be designed and delivered so that they effectively serve individuals, communities and businesses in the city? What other structures and processes are required to achieve this progress in a Smart City?
Read on to learn about the design of the infrastructures and systems of Smart Cities and view them visually represented in an accompanying diagram. Via Lauren Moss, Flora Moon Delete the scoop?
