Dr. Michael Oppenheimer shares the top three ways we all can help slow down global warming and save our planet.

1. Drive an energy-efficient car. Hybrids, cars that run on both gasoline and electricity, are the most fuel-efficient cars according to Consumer Reports.
   
2. Buy energy-efficient appliances. Look for the blue Energy Star label or visit www.energystar.gov.
   
3. Use energy-saving light bulbs. According to the Environmental Protection Agency (EPA), if every American household replaced 5 of their current light bulbs with 5 compact fluorescent light bulbs, it would save as much energy as if we took 8 million cars off the roads.
