A Performance Calculator For  Grid-Connected Pv Systems V2:   / (added 09/2005)
BTU Calculator:  Version 1 is the original PVWATTS. The user chooses a state from a map or a text list, and then the city of interest. The calculations may be done using the default system parameters, or the user may specify the PV system size, local electric costs, whether a fixed or tracking PV array, and the PV array tilt and azimuth angles. PVWATTS calculates monthly and annual energy production in kWh and monthly savings in dollars. The user may also choose to output hourly AC power data, which can saved to a text file. Version 1 can be run for Guam or Puerto Rico as well as the 50 states. 
Business Energy Analyzer :

The Web site also features a database of contractors to help you select an experienced building professional. Developed under funding from the California Energy Commission's Renewable Energy Consumer Education grant program.
Carboncounter :  is a Web-based calculator developed for the Canadian Wind Energy Association (CANWEA). This online wind calculator helps consumers determine the cost and benefits of installing small wind energy systems for their home, farm or building.
Climate Change Calculator - American Forests:  This CO2 calculator, based on the ChoCO2 studies of GEIC (the Global Environment Information Centre in Tokyo), calculates CO2 emissions from everyday Japanese electrical appliances and automobiles based on energy consumption figures. By marking the appliances you use and filling out the required information, you can get a quick idea of how you can impact on the environment through your lifestyle.
Co2 Calculator :  Carboncounter.org is an individual carbon dioxide emissions calculator generated by The Climate Trust, a pioneering non-profit organization that invests in high-quality projects that reduce or avoid greenhouse gas emissions, and Mercy Corps, an international relief and development agency.
Co2 Reduction Calculator:  This tool prepared for the Canadian government calculates personal greenhouse gas emissions and lists mitigation strategies. Using a graphical example of a Canadian community, the user answers a series of questions on home heating and cooling, appliances, transportation and recreation activities. The calculator estimates personal CO2 emissions, offers suggestions for reducing emissions, and shows reductions achieved for those actions. The reporting function provides a graphical emissions breakdown for each feature. Available online or as a downloadable file.
Co2 Reduction Calculator :  Calculates tons of carbon dioxide emitted by your household this year, and number of trees that would need to be planted to offset those emissions.  / (added 09/2005)
Energy Advisor / Home Energy Saver :  This calculator estimates the time and cost required to phase out CO2 production with a range of renewable energy technologies and carbon sinks. / (added 09/2005)
Energy Conversion Calculator:  This calculator estimates the time and cost required to phase out CO2 production with a range of renewable energy technologies and carbon sinks. / (added 09/2005)
Energy To Carbon Dioxide Converter :  The emissions calculator tabulates a user's aggregate monthly emissions of seven air pollutants (in pounds) from electricity and natural gas consumption, airplane trips, and vehicle miles traveled (auto or sport utility vehicle/truck) and compare them with average national emissions. Emissions profiles may be saved and updated monthly to track performance. The site also offers suggestions on reducing emissions. / (added 09/2005)
Energy To Carbon Dioxide Converter From National Energy Foundation:  new link -- The Home Energy Saver is designed to help you identify the best ways to save energy in your home, and find the resources to make the savings happen. The Home Energy Saver asks for a detailed description of your home, and then quickly computes energy use on-line. Results are provided in dollars, kilowatt-hours and CO2 emissions for your house and the most energy efficient house. By changing one or more features, you can estimate how much energy and money you can save and how much pollution you can prevent by improving your home's energy efficiency. In addition, the Home Energy Saver's "Making it Happen" and Energy Librarian" modules connect users to an expanding array of "how-to" information resources throughout the Internet.
Energy To Carbon Dioxide Converter From National Energy Foundation :  energy converter

Findsolar.Org:  A Worksheet to help you figure out what you energy needs are.
Greenhouse Gas Equivalencies Calculator - US Ctc Gateway :  Calculates the emissions savings from using Australian energy star equipment. Results list savings in kilowatt-hours, coal needed to provide this energy, kilograms CO2, and equivalent car travel. 
Home Analyzer :  This site provided by the US Environmental Projection Agency can be used to calculate a household's greenhouse gas emissions, as well as the impact of measures implemented to reduce these.
How Much Does Your Vehicle Pollute? :  new link -- Determines your auto's carbon dioxide, sulfur dioxide, and nitrogen oxide emissions. Will calculate values specific to your mileage, or typical for the year and make of your auto. Includes additional information explaining the significance of the result and what can be done to lower emissions.
