With More Bang for the Buck, Renewables Providing Most New Power ||

Renewables were the biggest new source of electricity last year as the cost of building new wind and solar farms fell.

Clean energy provided 55 percent of all new capacity added worldwide, the most ever, and total investment was about double the amount for generators driven by fossil fuels, according to a report published Thursday by UN Environment, the Frankfurt School-UNEP Collaborating Centre and Bloomberg New Energy Finance.

Investment in clean power dropped 23 percent from 2015 to $241.6 billion, meaning that the new capacity installed came at a lower price. The average capital expenditure for a megawatt of wind and solar fell more than 10 percent, according to the study, and they are some of the cheapest sources of electricity in some countries.

“Renewables are much more competitive than they were five years ago,” Angus McCrone, chief editor at Bloomberg New Energy Finance, said in an interview. “In an increasing number of places, wind and solar may be the cheapest option.”

Innovations in building intelligent cities ||

An artistic rendition of the Thermoheliodome, a pavillion that cools itself via evaporation using mirrored panels that reflect heat toward water-cooled pipes. It is one of several energy-saving concepts from Forrest Meggers, who is jointly appointed in Princeton’s School of Architecture and the Andlinger Center for Energy and the Environment.

Cities sprawl and tangle, juxtaposing ancient public squares and glistening skyscrapers. They provide homes for half of humanity, and economic and cultural centers for the rest.

The Sustainable SITES Initiative |

Washington Canal ParkLand is a crucial component of the built environment and can be planned, designed, developed and maintained to protect and enhance the benefits we derive from healthy functioning landscapes. SITES helps create ecologically resilient communities and benefits the environment, property owners, and local and regional communities and economies.

Administered by Green Business Certification Inc. (GBCI), SITES offers a comprehensive rating system designed to distinguish sustainable landscapes, measure their performance and elevate their value. SITES certification is for development projects located on sites with or without buildings—ranging from national parks to corporate campuses, streetscapes to homes, and more.

‘Whole Building’ Design | Balancing Security, Safety And Sustainability Objectives

nibs-ii

The gateway to up-to-date information on integrated ‘whole building’ design techniques and technologies. The goal of ‘Whole Building’ Design is to create a successful high-performance building by applying an integrated design and team approach to the project during the planning and programming phases.

Seeing Justice in Sustainable Light:

The new Alfred A. Arraj United States Courthouse in Denver, Colorado serves as a model for designs that balances openness, security, and sustainability. The building showcases innovative sustainable strategies, such as photovoltaic cells and daylighting using light shelves, while also being one of the first U.S. courthouses to meet the new “GSA Security Design Criteria” standards.

The lighting design provides a dramatic improvement in energy conservation and environmental performance over a conventionally designed courthouse. Most importantly, it provides a healthy, safe and productive working environment in courtrooms.

Coral Walls ‘Mesophotic Reefs’ Reveal New Type of Photosynthesis |

Now, researchers have discovered that the corals that inhabit this “Mesophotic zone” have a never-before-seen adaptation that enables them to eke out enough light energy to survive.

The photosynthetic algae that live on and power these corals have unusual cellular “machinery” that enables them to conduct photosynthesis more efficiently than species that live at shallower depths …             READ MORE
