The National Renewable Energy Laboratory (NREL) has enhanced its Alternative Fuels Data Center website in order to give fleets and other stakeholders more detailed information and strategies related to alt-fuel vehicles.
"From a single web page, a fleet manager can explore multiple strategies and know what the energy and environmental impacts will likely be before making any substantial investments," explains Witt Sparks, a project manager with NREL.
The tool allows fleet managers to create "what-if" scenarios - e.g., "What if I convert my pickup trucks to run on natural gas or propane?" - that ultimately help establish "a set of measurable objectives to meet desired goals." Charts and tables display annual reductions in emissions, petroleum use and fuel costs, and plans can be adjusted as needed and saved for future use.
