What would have been the Southern Hemisphere’s largest wind farm, a $2 billion NZD ($1.4 billion USD) and 630 MW wind farm in New Zealand, is not happening because New Zealand’s Environment Court says that it would ruin the surrounding landscape.
This project would have powered over a million homes and made a huge dent in New Zealand’s greenhouse gas emissions. It is not happening now because of a group of NIMBY activists and the Environment Court’s ruling.
This is a huge blow, in itself, to renewable and wind energy proponents, but it also brings concerns for future wind energy projects.
A new report ranks ten leading world cities on their greenhouse gas emissions. It also examines how and why the emissions differ.
As the report says, over 50% of the world’s population lives in urban areas. Leading cities of the world, global cities, are the places where greenhouse gas emissions really need to be cut. The greenest city from the study is Barcelona and the worst is Denver.

It’s clear electric vehicles (EVs) will be part of the transportation mix of the future.
President Obama has set ambitious goals for wide-scale adoption of EV technology. Advances in battery technology will help bring more electrified vehicles to market for consumers and the desire to reduce CO2 emissions has increased attention on transportation alternatives like electric vehicles and plug-in hybrids.
We live in an era where compute capability is ubiquitous, whether it be on a smart phone or mobile computer, and where “the cloud” can be accessed from anywhere.
In parallel, the ever-improving energy and carbon-efficiency of computers creates new opportunities to trade off atoms for bits, also known as de-materialization, and to substitute carbon-intensive activities, such as transportation, with tele-presence.
Here in Intel’s Eco-Technology group, we’re trying to learn precisely where these trade-offs exist, and under what conditions society can achieve net-positive outcomes, by harnessing technology in more environmentally beneficial ways. To that end, together with Microsoft’s sustainability group, we asked Dr. Jonathan Koomey, visiting professor at Yale’s School of Forestry and Environmental Studies and an expert in energy conservation technology, economics, policy and global climate change, to undertake a study of the environmental tradeoffs, between purchasing music in the traditional fashion (on CD from an online or brick and mortar store), versus purchasing and downloading the digital files.
The legendary glaciers of the Himalayan and Hindu Kush mountain ranges have been losing volume at an increasing rate over the past twenty to thirty years. And over this same time period, much data has piled up confirming the role of increased CO2 emissions in global warming trends. Given this, it would be “natural” to assume that CO2-induced warming was also to blame for the glacial melting. But it turns out that much stronger evidence points to the [...]
Editor’s Note: This is a guest post from David Hone, Climate Change Adviser for Shell.
I have been in Sao Paulo this week at Sustentavel 2009, perhaps the premiere Sustainable Development event in Brazil, if not all of South America. At the opening I represented the World Business Council for Sustainable Development and then on the first day of presentations I participated in the main climate change panel session.
What is clear is that there is a passion in Brazil for sustainability – from the huge issues they face in the Amazon region to the road congestion in Sao Paulo. Talking with delegates at Sustentavel, it is also clear that the country faces an interesting future in terms of greenhouse gas emissions.
This population growth, on the surface, would seem to be a matter of great concern. To be sure, it is indeed a concern in those countries as they seek to insure the survival needs of more and more people. But, as population and economic researchers have shown, population size alone is not the real problem; the real problem is the rate of consumption per capita. Put in this light, we immediately see a dramatic difference between first and third world [...]
Wastewater treatment facilities end up dumping a lot of mud that is extracted from the in-flowing water. And, like everything else, that mud takes up space. Space that could be used for other things, even at the dumping yards. But researchers from the Rovira i Virgili University (URV) have suggested, and successfully shown, that the waste mud doesn’t need to be taken to a dumping ground; rather, it can be used as fuel.
Carbon Capture and Storage (CCS) has the potential to cut global Co2 emissions dramatically. We’re talking huge cuts. It has been estimated that a plant implementing CCS can cut emissions by 80-90 percent compared with a plant that doesn’t use CCS. Sounds great, right? Well, there are some some problems.
Cost is the number one challenge that CCS faces. “Applying it would significantly increase the cost of electricity beyond what society is likely willing to pay,” said Sarah Forbes, a World Resources Institute Senior Associate. Another challenge is that no fully integrated demonstrations have taken place. The pieces have been tested individually, but the entire puzzle is yet to be seen.
Forbes describes CCS and its current challenges in more detail:
a broad coalition of consumer, economic and environmental advocacy groups has published a report on the substantial consumer savings that stronger energy efficiency and renewable energy standards would bring.
