Geothermal heat pumps: FEMP fact sheet (open access)

Geothermal heat pumps: FEMP fact sheet

A geothermal heat pump (GHP) system has three major components: a ground loop (buried piping system), the heat pump itself (inside the house), and a heating and cooling distribution system. GHP's are efficient and require no backup heat because the earth stays at a relatively moderate temperature throughout the year.

Solar ventilation preheating: FEMP fact sheet (open access)

Solar ventilation preheating: FEMP fact sheet

Installing a ''solar wall'' to heat air before it enters a building, called solar ventilation preheating, is one of the most efficient ways of reducing energy costs using clean and renewable energy. A solar wall can be designed as an integral part of a new building or it can be added in a retrofit project.

Solar water heating: FEMP fact sheet (open access)

Solar water heating: FEMP fact sheet

Using the sun to heat domestic water makes sense in almost any climate. Solar water heaters typically provide 40 to 80{percent} of a building's annual water-heating needs. A solar water-heating system's performance depends primarily on the outdoor temperature, the temperature to which the water is heated, and the amount of sunlight striking the collector.

Clean Cities Case Study: UPS delivers with Alternative Fuels (open access)

Clean Cities Case Study: UPS delivers with Alternative Fuels

In the fall of 1994, the UPS fleet in Landover, Maryland, began operating 20 vehicles on CNG. UPS selected CNG because natural gas is an abundant domestic resource that is available in almost every city in the US, and it also generally costs less than other fuels. The UPS project, funded by DOE through NREL and managed by TRI, was designed to test the feasibility of using CNG in a medium-duty pick-up and delivery fleet. This study is intended only to illustrate approaches that organizations could use in adopting AFVs into their fleets.

MICROBIAL TRANSFORMATIONS OF PLUTONIUM AND IMPLICATIONS FOR ITS MOBILITY. (open access)

MICROBIAL TRANSFORMATIONS OF PLUTONIUM AND IMPLICATIONS FOR ITS MOBILITY.

The current state of knowledge of the effect of plutonium on microorganisms and microbial activity is reviewed, and also the microbial processes affecting its mobilization and immobilization. The dissolution of plutonium is predominantly due to their production of extracellular metabolic products, organic acids, such as citric acid, and sequestering agents, such as siderophores. Plutonium may be immobilized by the indirect actions of microorganisms resulting in changes in Eh and its reduction from a higher to lower oxidation state, with the precipitation of Pu, its bioaccumulation by biomass, and bioprecipitation reactions. In addition, the abundance of microorganisms in Pu-contaminated soils, wastes, natural analog sites, and backfill materials that will be used for isolating the waste and role of microbes as biocolloids in the transport of Pu is discussed.
