Limited how to make sci dama board to supermarkets, supercenters, grocery stores, or other sources of healthy and affordable food may make it harder for some Americans to eat a healthy diet. There are many ways to measure food store access for individuals and for neighborhoods, and many ways to define which areas are food deserts—neighborhoods that lack healthy food sources.

Most measures and definitions take into account at least some of the following indicators of access:. In the Food Access Research Atlas, several indicators are available to measure food access along these dimensions. For example, users can peecent alternative distance markers to measure low access in a neighborhood, such hwat the number and share of people more than half a mile to a supermarket or 1 mile nukber a supermarket.

Users can also view other census-tract-level characteristics that provide context on food access in neighborhoods, such as whether the tract has a high percentage of households far from supermarkets and without vehicles, individuals with low income, or people residing in group quarters. This program defines a low-income census tract as any tract where:.

In the Food Access Research Atlas, low access to healthy food is defined as being far from a supermarket, supercenter, or large grocery store "supermarket" for short. A census tract is pegcent to have low access if a significant number or share of individuals in the tract is far from a supermarket.

A fourth and slightly nymber complex measure incorporates vehicle access directly into the measure, delineating low-income tracts in which a significant number of households are located far from 55 is 80 percent of what number supermarket and do not have access to a vehicle.

This measure also includes census tracts with populations that are so remote, that, even with a vehicle, driving to a supermarket may be considered a burden due to the great distance.

Using this measure, an estimated 2. An additional 0. Qhat used to assess distance to the nearest supermarket are the same for each of these measures. Once distance to the nearest supermarket is calculated for each grid cell, the estimated number of people or housing units that are more than 1 mile from a supermarket perceht urban tracts, or 10 miles pecrent rural census tracts, is aggregated at the census-tract level and similarly for the alternative distance markers.

A census tract is considered rural if the population-weighted centroid of that tract is located in an area with a population of less than 2,; all perceny tracts are considered urban tracts. The Food Access Research Atlas maps census tracts that are both low income li and low access laas measured by the different distance demarcations.

This tool provides researchers and other users multiple ways to understand the characteristics that can contribute to food deserts, including income level, distance to supermarkets, and vehicle access.

Whether a vehicle is available to a household for private use is an important additional indicator of access to healthy oof affordable food. For households living far from a supermarket or large grocery store, access to a private vehicle may make accessing these retailers easier than relying on public or alternative means of transportation. A tract is identified as having low vehicle availability if more than households in the tract report having no vehicle available and are more than 0.

This corresponds closely to the 80 th percentile of the distribution of the number of housing units in a census tract without vehicles at least 0. This means that about 20 percent of all census i had more than housing units that were 0. This indicator was applied to both urban and rural census tracts. Overall, 9.

Vehicle availability is defined in the American Community Survey as the number of passenger cars, vans, or trucks with a capacity of 1-ton or less kept at the home and available for use petcent household members.

The number of available vehicles includes those vehicles leased or rented for at least 1 month, as well as company, police, or government vehicles perent are kept at home and available for non-business use. Users may be interested in highlighting tracts with large shares of people living in group quarters.

Group quarters are residential arrangements where an entity or organization owns and provides housing and often services for individuals residing in these buildings.

This includes college dormitories, military quarters, correctional facilities, homeless shelters, residential treatment centers, and assisted living or skilled nursing facilities. These living arrangements frequently provide dining and food retail solely for their residents. While individuals living in these areas may 55 is 80 percent of what number to be far from a supermarket or grocery store, they may not truly experience difficulty accessing healthy and affordable food. Tracts in which 67 percent of individuals or more live in group quarters are highlighted.

CHP offers a number of benefits compared to conventional electricity and thermal energy production, including:. Efficiency Benefits CHP requires less fuel to produce a given energy output and avoids transmission and distribution losses that occur when electricity travels over power lines. Environmental Benefits Because less fuel is burned to produce each unit of energy output and because transmission and distribution losses are avoided, CHP reduces emissions of greenhouse gases and other air pollutants.

Economic Benefits CHP can save facilities considerable money on their energy bills due to its high efficiency, and it can provide a hedge against electricity cost increases. Reliability Benefits Unreliable electricity service represents a quantifiable business, safety, and health risk for some companies and organizations. CHP is an on-site generation resource and can be designed to support continued operations in the event of a disaster or grid disruption by continuing to provide reliable electricity.

Efficiency can be calculated a number of ways; however, the efficiency numbers that EPA cites are "total system efficiency," defined as the total electricity and useful thermal energy output of the system divided by the fuel used to produce the electricity and useful thermal energy. Learn about the different methodologies and how to use them at Methods for Calculating Efficiency.

The average efficiency of fossil-fueled power plants in the United States is 33 percent. This means that two-thirds of the energy used to produce electricity at most power plants in the United States is wasted in the form of heat discharged to the atmosphere.

By recovering this wasted heat, CHP systems typically achieve total system efficiencies of 60 to 80 percent for producing electricity and useful thermal energy. Some systems achieve efficiencies approaching 90 percent. The illustration below demonstrates the efficiency gains of a 5 megawatt MW natural gas-fired combustion turbine CHP system compared to conventional production of electricity and useful thermal energy i. This is an example of a typical CHP system.

To produce 75 units of electricity and useful thermal energy, the conventional system uses units of energy inputs for electricity production and 56 to produce useful thermal energy-resulting in an overall efficiency of 51 percent.

However, the CHP system needs only units of energy inputs to produce the 75 units of electricity and useful thermal energy, resulting in a total system efficiency of 75 percent. A CHP system's efficiency depends on the technology used and the system design.

The five most commonly installed CHP power sources known as "prime movers" offer these efficiencies:. Losses can be even higher when the grid is strained and temperatures are high. CHP systems offer considerable environmental benefits when compared with purchased electricity and thermal energy produced on site. By capturing and utilizing heat that would otherwise be wasted from the production of electricity, CHP systems require less fuel to produce the same amount of energy.

Because less fuel is combusted, greenhouse gas emissions, such as carbon dioxide CO 2 , as well as other air pollutants like nitrogen oxides NO x and sulfur dioxide SO 2 , are reduced. The following diagram shows the magnitude of reduced CO 2 emissions of a 5 megawatt MW natural gas-fired CHP system compared to the same energy output from conventional sources.

This diagram illustrates the CO 2 emissions output from electricity and useful thermal energy generation for two systems: 1 a fossil fuel-fired power plant and a natural gas-fired boiler; and 2 a 5 megawatt combustion-turbine CHP system powered by natural gas.

The separate heat and power system emits a total of 45 kilotons of CO 2 per year 13 kilotons from the boiler and 32 kilotons from the power plant , while the CHP system, with its higher efficiency, emits 23 kilotons of CO 2 per year. The economic benefits of any CHP project are dependent on electricity rates, system design, equipment cost and CHP operating practices. The value of the benefits will depend on the needs and goals of the investor.

A feasibility analysis is conducted to determine the technical and economic viability of a project. In addition to reducing operating costs, CHP systems can be designed to continue operating in the event of grid outages to supply continuous power for critical functions.

Interruptions of grid-supplied electricity service represents a quantifiable business, safety, and health risk for some facilities. Valuing the Reliability of Combined Heat and Power provides methods to estimate the value of CHP as electricity supply reliability measure and the merits of different design strategies.

Economic Benefits CHP can offer a variety of economic benefits, including: Reduced energy costs: CHP reduces energy bills because of its high efficiency. By using waste heat recovery technology to capture wasted heat associated with electricity production, CHP systems typically achieve total system efficiencies of 60 to 80 percent, compared to 50 percent for conventional technologies i.

Basically less fuel is needed for a given unit of energy output. Also, because CHP systems typically use natural gas which is often cheaper than purchased electricity, CHP can help reduce electricity bills.

Bills are further reduced because the CHP output reduces electricity purchases. Avoided capital costs: CHP can often reduce the cost of replacing heating equipment. Protection of revenue streams: Through onsite generation and improved reliability, CHP can allow facilities to continue operating in the event of a disaster or an interruption of grid-supplied electricity.

Less exposure to electricity rate increases: Because less electricity is purchased from the grid, facilities have less exposure to rate increases. In addition, a CHP system can be configured to operate on a variety of fuel types, such as natural gas, biogas, coal, and biomass; therefore, a facility could build in fuel switching capabilities to hedge against high fuel prices.

Use our questionnaire as a preliminary assessment of whether your facility might be a good candidate for CHP. Visit the Project Development section of this Web site to learn about the steps required to consider and install a CHP system. Reliability Benefits In addition to reducing operating costs, CHP systems can be designed to continue operating in the event of grid outages to supply continuous power for critical functions. The first step in incorporating CHP into a strategy to reduce business risk is to calculate the value of reliability and risk of outages for a specific facility.

After identifying and quantifying in monetary terms the value of reliable power to facility operations, the costs of designing and configuring CHP technology for outage protection can be estimated and evaluated. CHP systems can be configured to meet the specific reliability needs and risk profiles of any facility.
