The Summit follows the American Wind Energy Association's (AWEA's) annual WINDPOWER Conference and Exhibition, June 1-4, in Houston, Texas. Each year, AWEA's WINDPOWER conference brings together the industry's leading wind energy professionals from around the world for 3 days of conference sessions and an interactive tradeshow where exhibitors showcase their products and services.
On the day following WINDPOWER, the Wind Powering America (WPA) program convenes its Annual State Summit. The Summit provides Wind Powering America's network of state wind working groups, state energy officials, DOE and national lab WPA representatives and its professional and institutional partners an opportunity to review successes, opportunities and challenges for wind at the state level. Participants share strategies/lessons learned, review priority activities/topics, and celebrate and recognize accomplishments among peers. The Summit features plenary sessions, regional and state breakouts, and smaller group discussions on focused issues, as well as presentations and remarks from invited national guest speakers. Summit participants will include leaders of Wind Powering America's state wind working groups, institutional partners, wind industry experts, and DOE and National Laboratory staff.
Tibet has become an increasingly popular destination on responsibletravel.com. We've hand-picked 28 of the very best holidays there, and last year it was our 49th most popular destination globally.Transforming useless, black rooftops into prosperous, green gardens — that is the goal of Dr. Paul Mankiewicz.
As director of the Gaia Institute, an environmental research group in New York City, he has designed a unique greenhouse which solves the complexities of gardening on rooftops and will provide fresh produce for thousands of residents below.
By using a lightweight soil, a simple steel-frame structure wrapped in plastic, and a unique planting and harvesting system, this new greenhouse could add a new facet to agriculture. And that has the biologist excited.
“If we have a system that can purify the air and lower the amount of traffic needed to ship produce — and have that system in cities where pollution problems are serious — that is certainly a big improvement for society,” he said. “And by having a new center of economic activity right in the cities, it makes for a much greater increase in wealth for those urban areas.”
After seven years of research and development, Mankiewicz has applied for a grant from the Environmental Protection Agency to build a prototype greenhouse on a building owned by the Cathedral of St. John the Divine, New York City’s fifth most popular tourist attraction.
Tied to the grant is New York City’s Recycling Division, which will help supply the ton of solid waste the greenhouse will use every day. Food scraps and other waste material will be composted in large bins, Mankiewicz said, then slurried up to the roof where the material will be used in both the soil and the nutrient system.
The greenhouse’s soil is the unique feature that makes the system work. Most soils are too heavy to use on rooftops, he said, and building additional reinforcement is too expensive.
However, he has created a super lightweight soil by using both synthetic and organic materials, including recycled styrofoam. The styrofoam works as filler — the purpose sand and clay serve in most soils.
Feeding the crops involves a series of underground tubes linked to a controller, which delivers precise amounts of water, nutrients, microbes, carbon dioxide and oxygen to maximize plant growth.
Covering the plants will be a lightweight steel frame covered with a thin glazing of plastic. By his calculations, Mankiewicz said the amount of petroleum needed to produce all the plastic used in the greenhouse would get a truckload of produce only 300 miles down the road from California.
For planting and harvesting, a space-saving gantry system will span the garden and roll over the top of the growing space. Workers will be able to work from above, he said, eliminating the need for aisles and increasing crop yields by 30 to 90 percent.
On a larger scale, Mankiewicz envisions rooftop greenhouses eventually adorning the tops of shopping malls. With tens of thousands of square feet available, a shopping mall greenhouse could supply all the produce for an entire community. And by increasing the profits of both store and mall owners, he said the technology could leap ahead, becoming a new green layer of the urban environment.
(Tip/Stat ) Composting can reduce solid waste by more than 15 percent.

Biofuels, particularly ethanol, have had plenty of recent hype as a possible homegrown replacement for gasoline. However, production of corn-based ethanol in the United States is driving up grain prices and possibly harming the environment.

In January we did a survey for The Daily Telegraph of the 40 of the biggest travel companies in UK and their policies for responsible tourism. One of the companies we scored quite poorly was Europcar (car hire). Last weekend the Telegraph ran the following story -

This presentation illustrates the evolution of commercial wind technology in the United States, how capacity in megawatts has increased while costs have decreased, and that people want renewable energy. The United States leads the world in annual wind capacity additions and is second in cumulative capacity. The U.S. lags behind other countries for wind as a percentage of electricity consumption. The presentation also shows a map of the United States' installed wind capacity in 2007 compared to 1999. It goes on to lists the drivers for wind power; illustrates wind cost of energy, natural gas and coal historic prices, renewable portfolio standards, and wind energy investors; lists economic development impacts of wind energy; lists environmental benefits; highlights water issues; highlights case studies and local ownership models; lists key issues for wind power; discusses the 20 percent wind-electricity vision, market challenges, job creation, water savings, and carbon savings.
With the proper resources, wind power and wood chip boiler projects can provide cost savings while simultaneously offering living laboratories for renewable energy systems within our schools, colleges, and cities. Come learn who is doing this now and how to bring this vision to your institution.
The workshop is for administrators and facilities managers for public institutions such as K-12 school districts, higher education institutions, and municipalities who are looking toward sustainable energy systems with the following goals:

New to the site this week is our first Cave hotel! The hotel is located in a restored thousand-year-old Byzantine monastic retreat in Turkey which offers modern conveniences without distracting from the spiritual feeling of the area. Part of the hotel was used by Christian monks until recently. Some of the rooms were actually monk cells. The food is produced with the technical assistance of Rapunzel Bio-Farming company. As for fertilizer, we use the cow dung and pigeon droppings from cave pigeon houses
