Site erosion control, while often overlooked is an important part of sustainable building practices. Erosion from building sites silts up waterways amongst other things so minimizing it is critical for achieving the goal of low impact development. In this post, Bob goes on to suggest five techniques that architects and builders can use to help to prevent erosion and sediment loss and ensure that the building of the green building is itself green.
This post looks at some of the financing and perception challenges that the renewable energy sectors need to meet in order to compete with the much better organized and currently profitable fossil energy sectors. The author would like to see a greater focus in the renewable sector on the specific needs of the companies in the industry and makes the argument that companies in the renewable sector need to do a better job in how they present their case if they want to compete with the red hot oil & gas sectors with investors.
In this post Peg summarizes a round-table discussion about cleantech financing in the global economy held at 5th Annual Babson Energy and Environmental Conference on Entrepreneurship for a Sustainable Future and chaired by Mark Donohue. The discussion covered some of the global aspects affecting cleantech financing and looked at various challenges and opportunities lying ahead.
The WINDPOWER 2011 Conference & Exhibition, organized by the American Wind Energy Association (AWEA), is coming up this month and will run from May 22nd through the 25th, and will be held this year in Anaheim, California. On Sunday May 22nd, it will kick off with a Careers in Wind Summit, a full, one-day event that precedes WINDPOWER, and consists of two concurrent parts: the WINDPOWER “Careers in Wind” Educational Seminars, and the WINDPOWER “Careers in Wind” Job Fair & Exhibition.
Building a green data center is a challenging undertaking; it is also one that is poorly understood and that can fail in many ways. This post goes into some of the deeper level goals that need to be kept in focus if the project is going to be a success.
While other parts of the world are busy actually building national Ultra High Voltage (UHV) transmission infrastructure the US continues to do noting more substantial than litigate. A UHV super grid would be able to move renewable energy from where it is abundant to where people live and work, and do so at an economic cost. This kind of national electric energy infrastructure would enable solar, wind, hydro and geothermal generated electric power to reach market. It is a critical piece of the kind of future energy infrastructure we will need in order to continue to prosper. John goes into a lot of detail and provides numerous links to examples and more in depth reading on this very important subject.
Energy systems need to also be measured according to the potential risks associated with them in the advent of failure. And the actuarial costs of these risks need to be better understood and included into the market price for the energy that these systems produce. This post examines this catastrophic downside risk of nuclear and fossil energy focusing on the recent events in Japan and on the BP oil spill as two recent examples of hugely expensive catastrophes. It poses the question why should the taxpayers and the public bear the burden of these costs in this manner artificially lowering the price these energy sectors are thus able to charge for their products.
Biomimicry has probably been practiced by humans for as long as we have been walking the earth. In our current cultural context, Janine Benyus, has popularized this design philosophy and coined the term biomimicry, helping to generate a new wave of interest in this design approach. Biomimicry seeks to mimic the evolved design solutions arrived at by nature and adapt them to and incorporate them into the design of structures and products. It uses nature as a model to inspire design solutions; it uses nature as a measure of elegance and rightness of a design; and it seeks to promote the notion of nature as mentor that we may learn from, rather than as an inert object to exploit.
indoor marijuana weed cannibisThe yearly greenhouse-gas pollution of the $40 billion per year marijuana industry is responsible for about 3% of all electricity use or 8% of household use. Indoor growers use high-intensity lights that are 500 times more powerful that a standard reading lamp. They also use several other high energy industrial practices. The closest comparison for these massive, industrial-style grow facilities are data centers, which consume about two percent of the nation’s electric power.
