Leveraging Contaminated Sites for Renewable Energy Opportunities

clock September 1, 2011 03:53 | commentComments (0)
Renewable energy (RE) investments are seen by many as “iffy” propositions. Relying on regulatory measures, fossil fuel energy prices, and often some form of government subsidies, conventional wisdom would argue that burdening such projects with yet even more regulated activities would be foolhardy, at best. Decades of efforts to remediate and re-use previously contaminated lands have resulted in the clearing of all property buildings to make them competitive with “greenfield... [More]

Philadelphia Public-Private Partnership Structure—Biogas Cogeneration Plant

Several years ago, the Philadelphia Water Department realized that it needed additional heat to operate its wastewater processing facility. To address that need, the city designed a facility that generates electricity and heat using methane gas derived from wastewater sludge. The city originally planned to finance the facility by issuing tax-exempt bonds. It also expected to own and operate the facility, because generating biogas, electricity, and heat would be tightly integrated with the op... [More]

Denver Zoo Leading by Example: Using Biomass Gasification to Create Energy from Waste

Project Vision Colorado’s Denver Zoo is evaluating a technology called biomass gasification to provide electricity and low temperature heat for the facility. This technology, which gasifies mixed wastes such as cardboard, wood, paper, and animal wastes, has both environmental and economic benefits. Implementing biomass gasification would reduce the zoo’s greenhouse gas (GHG) emissions, eliminate 750 tons of landfill waste per year, cut down on the amount of fossil fuel-produced el... [More]

Don’t Just Do Both, Do Both Together!

Like Chocolate and Peanut Butter, Energy Efficiency and Renewable Energy Initiatives Go Best Together! When initiating a planning process, bundling efficiency and renewables—considering both as parts of a single energy system—allows people to more effectively use both types of technologies in clean energy projects. In addition, designing programs that incorporate both technologies allows for greater leveraging power and broader funding opportunities than if one technology we... [More]

SolOpt takes the Guesswork out of Optimizing Solar Technology on Rooftops

clock March 1, 2011 06:12 | commentComments (1)
As facility owners across the country look for ways to cost-effectively deploy solar technologies throughout their entire building stock, there is an increasing need for a standardized solar rooftop optimization tool. Traditionally, photovoltaic (PV) and solar hot water (SHW) technologies have been designed with separate design tools, which can make it difficult to determine the appropriate mix of PV and SHW for a single rooftop. In the current marketplace, when a building is assessed for it... [More]
