year,make,model,engine size, a/c on or off? drl's? headlights on?, heater on? outdoor temp? ... too many variables so ill say sitting at stoplights is a 100% waste of gas. :)
Headlight Use versus Fuel ConsumptionThe use of headlights does cause a very tiny [almost infinitesimal] amount of extra fuel consumption, BUT...To call it a waste is ridiculous as the increased safety the headlights provide far offsets the minute cost, and thus does NOT waste "gas."
waste it.
Refuse-derived Fuel(RDF) is a fuel produced by processing municipal solid waste (MSW) with a waste converter technology.
water vapour
It is highly radioactive (that is the waste contained in the spent fuel)
The waste product of fuel cells is typically water and heat. When hydrogen is used as the fuel source, the only byproducts are water vapor and heat, making fuel cells a very clean and efficient energy source.
Because it is expensive.
The waste produced from a fuel cell depends on the type of fuel cell. Common waste materials include heat, water, and small amounts of carbon dioxide. Some fuel cells may also produce small amounts of pollutants or byproducts that need to be managed.
yes, if fuel is going to sit for extended periods you need to add fuel stabilizer to it
about 98,348 gallons per minute of all fuels used combined.
fuel pumps go bad after sitting for a while, check that
