Since a 1999 ban on two-stroke, carburetor engines went into full effect in 2001, levels of burned and unburned gasoline products in Lake Tahoe have declined by 80-90 percent according to the Tahoe Regional Planning Agency (TRPA). The 1999 ban was instituted by the Governing Board of the TRPA, a bistate organization established to protect the lake. The board voted in favor of the engine ban after it reviewed data that estimated each day of the boating season resulted in carbureted two-stroke engines releasing 770 gallons of fuel into the lake.

The Sacramento Municipal Utility District’s (SMUD’s) Advantage Home program requires a home to consume 25-50 percent less energy for cooling than the existing state energy code allows. When coupled with rooftop solar cells, these Solar Advantage homes are nearly energy self-sufficient on an annual basis. A Solar Advantage Home can result in $450 in yearly energy cost savings for homeowners.
