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.

Cars that change colour at the push of a button; metals that strengthen with use; buildings that harness energy from the wind... research into designing structural materials that are both responsive and functional is shifting such ideas from the realm of fantasy to reality.
Designing structural materials that can also harness energy is another important focus.
"We put solar cells on the roof: they play no structural role. We should be able to design materials that do both. On a windy day, buildings sway and that energy should be collected," Associate Professor Hutchinson said.
"We're working on ways to cheaply functionalise structural materials so that different forms of energy (mechanical, electromagnetic, etc) can be harvested from them.
"I see a future where there is no difference between functional and structural materials, but we design multi-functional materials that can do both."

Amsterdam-based Hofman Dujardin Architects, in collaboration with Fokkema & Partners, has helped sustainable energy company Eneco practice what it preaches with the design of its headquarters in Rotterdam. The 14-floor office has been operational since April, with employees enjoying one of the Europe's best workspaces. The heart of the building is a central atrium surrounded by a light-filled meeting centre with a reception space, meeting rooms, working areas, informal meeting areas, lounges, restaurant, service desk and auditorium. Sun collectors on the south façade and on the roof track the sun throughout the day, absorbing the maximum amount of solar energy. The working and meeting areas are designed to be energetic islands floating on a white terrazzo floor. Some islands are open spaces and others enclosed for privacy but they are all executed with vibrant colours and materials. Those on the ground floor are red, purple and orange, while those on the first floor are in different shades of verdant green (meeting rooms) and blue (working spaces). The diversity of color and materials on the work islands are not only lively and inviting but give the different spaces specific identities and atmospheres that enable people to orientate themselves better in the office. Learn more about the sustainable strategies incorporated into the design of this green office space at the article link... Via Lauren Moss Delete the scoop?

3.5 percent of U.S. counties consume more than 10 percent of the nation's oil. America consumes a lot of energy. Counties play a large role in this overall consumption — and many of them contain large cities like Los Angeles and Chicago. Deron Lovaas, the federal transportation policy director for the Natural Resources Defense Council, posted a map charting oil consumption by county on the NRDC staff blog Thursday. The map is the product of a joint research effort of the NRDC, the Sierra Club, and the League of Conservation Voters to identify the most oil dependent locations across the United States. As shown in the map (and accompanying list of national averages), oil consumption is geographically uneven and highly concentrated. Lovaas notes that "just 108 counties out of the nation's 3,144, or about 3.5 percent of the total consume more than 10 percent of the nation's oil." Not surprisingly, Los Angeles county had the most annual oil consumption, at nearly 1.9 billion gallons in 2010. Harris county, Texas, follows with 1.7 billion gallons, and Cook county, Illinois, takes third with 1.6 billion. Via Lauren Moss Delete the scoop?

In the current issue of Wood Bioenergy US (WBUS), Brooks Mendell and Amanda Lang focus on two aspects of regional wood bioenergy markets. First, they review the potential demand for pulpwood and chips by region to address the question “where does wood bioenergy most directly affect timberland investors and forest industry procurement managers at pulp mills and OSB plants?” Second, they evaluate the ability of regional markets to absorb and support new wood bioenergy projects by prioritizing regions with large, established, high-volume pulpwood markets, suppliers and the related infrastructure. The results show how “market depth” helps explain why new wood bioenergy investment and projects migrate to different parts of the United States, especially the US South (see Figure).

Energy conservation starts at home.... This interesting National Geographic article emphasizes how consumption patterns in the home are connected to some of the serious global issues that we currently face. This article becomes an exploration into how to go about creating a more environmentally sustainable home. Via Seth Dixon

Electricity usage derived from product testing between 2011 and 2012. The infographic shows the hot water heater using the lion's share of the power. However this is based on electric hot water heaters using an off-peak rate. If you have solar, heat pump or high-efficiency gas, then your water heating costs are likely to be much lower. As a general rule, the older your appliances are, the more likely they are to use more energy. For example in late-2009 over 50% of new TVs had an energy rating of less than 4 stars. By mid-2011 this number had dropped to less than 10%... Via Lauren Moss, Jose Cisneros Delete the scoop?

Fossil-fuel subsidies are a growing fiscal burden that encourage wasteful consumption. See which countries have the largest subsidies around the world.
Nations are weighing phaseout of fossil fuel subsidies, a growing fiscal burden that ratchets up carbon dioxide emissions by encouraging wasteful oil, natural gas, and coal consumption. The largest subsidies are in developing countries, which spend more than $400 billion annually shielding their populations from high fuel prices. But oil industry tax breaks and other government measures in developed nations also subsidize fossil fuels, to the tune of $45 billion to $75 billion per year.

"Economic growth in Europe will be affected by the costs of this transition from the current energy and transport system. A smooth transition towards a low-carbon energy and transport system could come at comparatively modest cost. Furthermore, identifying the most economically beneficial solutions early on and becoming a global technology leader and standard setter offers vast opportunities for exports and economic growth. Hence, our decarbonisation strategy may eventually have a greater impact on long-term European growth than the current economic crisis."
