Tells how the people of Danish island of Samso decided to use wind energy to power their lives and became the "Energy Island."

There are twenty million acres of lawns in North America. In their current form, these unproductive expanses of grass represent a significant financial and environmental cost. However, viewed through a different lens, they can also be seen as a tremendous source of opportunity. Access to land is a major barrier for many people who want to enter the agricultural sector, and urban and suburban yards have huge potential for would-be farmers wanting to become part of this growing movement. The Urban Farmer is a comprehensive, hands-on, practical manual to help you learn the techniques and business strategies you need to make a good living growing high-yield, high-value crops right in your own backyard (or someone else's). Major benefits include: Low capital investment and overhead costs Reduced need for expensive infrastructure Easy access to markets Growing food in the city means that fresh crops may travel only a few blocks from field to table, making this innovative approach the next logical step in the local food movement. Based on a scalable, easily reproduced business model, The Urban Farmer is your complete guide to minimizing risk and maximizing profit by using intensive production in small leased or borrowed spaces. Curtis Stone is the owner/operator of Green City Acres, a commercial urban farm growing vegetables for farmers markets, restaurants, and retail outlets. During his slower months, Curtis works as a public speaker, teacher, and consultant, sharing his story to inspire a new generation of farmers.

Is wind power the answer to our energy supply problems? Is there enough wind for everyone? Is offshore generation better than onshore generation? Can a roof-mounted wind turbine generate enough electricity to supply a typical domestic household?Electricity Generation Using Wind Power (2nd Edition) answers these pressing questions through its detailed coverage of the different types of electrical generator machines used, as well as the power electronic converter technologies and control principles employed. Also covered is the integration of wind farms into established electricity grid systems, plus environmental and economic aspects of wind generation.Written for technically minded readers, especially electrical engineers concerned with the possible use of wind power for generating electricity, it incorporates some global meteorological and geographical features of wind supply plus a survey of past and present wind turbines. Included is a technical assessment of the choice of turbine sites. The principles and analysis of wind power conversion, transmission and efficiency evaluation are described.This book includes worked numerical examples in some chapters, plus end of chapter problems and review questions, with answers. As a textbook it is pitched at the level of final year undergraduate engineering study but may also be useful as a textbook or reference for wider technical studies.
