\"Source:In Dublin, Ohio, the Community Recreation Center decided to reduce<\/a> its energy waste. Rather than rely on an electric utility to burn more coal or natural gas to provide electricity, as well as its own boilers to burn more fuel to provide heat, the facility decided to install a combined heat and power (CHP) unit.<\/p>\n

The CHP or \u201ccogeneration\u201d project produces both electricity \u2013 allowing the Center to keep its lights on during power outages \u2013 and heat \u2013 keeping offices and swimming pools warm. The CHP unit is financed with private capital and will allow the Center to save roughly 10 percent on its energy bills.<\/p>\n

\u201cIt\u2019s pretty simple,\u201d said<\/a> Patrick Smith, a co-developer of the Dublin project. \u201cIt\u2019s a generator, and we happen to capture the heat.\u201d<\/p>\n

Technology of the past\u2026<\/strong><\/p>\n

Cogeneration is not a new concept or technology. In fact, Thomas Edison\u2019s first power plants sold both heat and electricity to nearby buildings and factories. Yet to electrify America quickly in the early 20th<\/sup> century, policymakers and power companies created monopoly electric utilities that were protected from competition and guaranteed profits based on how much money they spent. As a result, for many decades, utilities favored larger and larger power plants that were placed far away from the buildings and factories that could have used their wasted heat. \u00a0<\/p>\n

America, of course, has long been electrified, but the model of monopoly-owned and electric-only power plants persists. And the waste is substantial. The typical power plant burns three units of fuel to generate just one unit of electricity. That 33 percent efficiency rate has not improved by a single percentage point since the late 1950s. Can you imagine if our cars wasted two-thirds of gasoline we put in them every time we filled up?<\/p>\n

The typical power plant burns three units of fuel to generate just one unit of electricity. That 33 percent efficiency rate has not improved by a single percentage point since the late 1950s.<\/p><\/blockquote>\n

CHP units, in contrast, achieve efficiencies of 60 to 90 percent. When designed and engineered appropriately for the facility in which they’re installed, they also significantly reduce<\/a> on-site emissions of carbon dioxide and other pollutants, such as nitrogen oxides (NOx) and sulfur oxides (SOx).<\/p>\n

Fortunately, lawmakers and regulators are beginning to pay attention to CHP. The U.S. Environmental Protection Agency, for instance, identified efficient cogeneration as a means to meet the proposed Clean Power Plan<\/a>, the nation\u2019s first-ever limit on carbon dioxide pollution from existing power plants. That\u2019s why the Ohio Environmental Council<\/a> and Environmental Defense Fund recently asked the Public Utility Commission of Ohio to support Ohio Power Company and Kraton Polymers\u2019 joint application<\/a> to use a new CHP project to help the utility meet its energy efficiency goals.<\/p>\n

Currently, CHP provides 12 percent<\/a> of U.S. electricity, virtually the same as solar, wind, biomass, and hydropower combined<\/em>, but, according to the Oak Ridge National Laboratory, CHP could supply as much as 20 percent<\/a> of U.S. electric capacity by 2030. If CHP reaches this threshold, it would:<\/p>\n
