A typical incandescent lamp (traditional light bulb) consumes 60 watts of power. How much do each of a compact fluorescent and LED lamp consume, in watts, to produce the same amount of light?

  • Sorry, that’s incorrect.

    A typical incandescent lamp (traditional light bulb) that consumes 60 watts of power produces around 800 lumens. A compact fluorescent lamp emits the same amount of light while using only 13 watts. And an LED lamp consumes only 10 watts to give off the same 800 lumens.

According to the Corporate Average Fuel Economy (CAFE) standards, what is the average miles per gallon (mpg) required for new cars, SUVs, and light trucks (combined) by 2025?

  • Sorry, that’s incorrect.

    The most recent federal efficiency standards, finalized by the U.S. National Highway Traffic Safety Administration (NHTSA) and the Environmental Protection Agency (EPA) in 2012, are projected to increase fuel economy to the equivalent of 54.5 mpg for cars and light-duty trucks by model year 2025, while also reducing CO2 emissions.

How are battery electric vehicles and hybrid vehicles different?

  • Sorry, that’s incorrect.

    Battery electric vehicles have only a motor and battery, they recharge from the grid and their carbon emissions depend on the energy used to generate the electricity they use. Hybrid vehicles have both a gasoline engine and an electric motor, and use petroleum onboard when their batteries are exhausted. Some hybrid vehicles can charge from the grid and others cannot. 

  • Sorry, that’s incorrect.
