Smart Power: An Urban Guide To Renewable energy and efficiency - Tapa blanda

Concern over energy supply, costs, and environmental problems are not limited to those prepared to venture into the countryside to an off-grid life. Urban people—now the vast majority in the Western world—share the same fear about what lies ahead. The average North American family will spend over one quarter million after-tax dollars on energy in a lifetime.

$mart Power shows homeowners that using less energy or adopting renewable-energy technologies is not about making drastic lifestyle sacrifices, nor is it expensive. In fact, energy efficiency often improves lifestyle through lower operating costs, a more comfortable environment, and increased disposable income.

Richly illustrated, chapters include energy efficiency, space heating and cooling, community power, energy efficient transportation, photovoltaics, wind and bio-fuels, batteries, voltage regulation and inverters, solar water heating, and backup power.
