Greening Your Electricity

A closer look at the environmental benefits of green power, including on-site renewables, what REC buyers should know about their purchases, and investing in energy conservation

Researchers suggest there are times when wasting wind energy makes sense. Building so many turbines that energy is wasted at peak production may be more energy efficient than building storage for fewer turbines.

Buildings account for roughly 72% of electricity consumption in the United States. Appliances, equipment, and lighting throughout those buildings may be powered by electricity of different voltages or different types of current, but it doesn’t matter to those appliances how the electricity is generated. The owners and occupants of the buildings, however, are increasingly recognizing the environmental differences between power from renewably generated and conventional sources, and are choosing to pay more, in some cases, for green electricity.

This article examines why many customers are greening their electricity and weighs various options, including buying grid-sourced renewable energy, buying renewable energy credits (RECs), investing in on-site renewable capacity, and reducing energy demand through conservation. The article also looks at the major certification efforts and issues in the REC market and provides examples from architectural firms and others who have invested in one or more of these areas.
