Spiraling fuel costs, frequent power cuts, “energy wars” with fuel-rich countries holding consumers to ransom--these are just some of the issues that are helping to ensure that microgeneration of power, at the individual building level, is becoming a more and more attractive option to grid power.
In this book author Dave Parker describes the many and varied microgeneration options, from wind turbines and solar power to biomass and heatsinks, and even gives advice on how architects and developers can best access the increasingly large amount of government funding to help implement these strategies.
This book can help those in the building and construction industry to really make a difference in the fight against climate change, by explaining how to utilize the technology already within our reach.
- Comprehensive review of the latest technology available
- Shows how to assess/compare/combine the merits of the available systems
- Gives hard information on how to adopt appropriate microgeneration technology for a specific project
Architects, developers, urban planners, self builders
Introduction How microgeneration is the most important potential contributor to sustainable construction. New incentives to go down the microgeneration route. Potential rewards, pitfalls to avoid. Changing government attitudes, new awareness amongst clients, tenants and energy companies.
