PROBLEMS
Global warming is real and is a natural process.
➢ Energy source and its associated emissions
from production are important to EV discussion.
➢ EVs are powered by Renewable energy sources
➢ Emissions are less than half of conventional
➢ Emissions when only source of energy is
accounted for
• 4587 pounds of CO2 annually for EVs
• 23885 pounds of CO2 annually for conventional
powered cars

POWER
SOURCE
• Lithium-ion batteries power electric cars
• Up to 335 miles of travel on single charge,
depending on type of car.
• Energy density has increased overtime from
1992
• Cost has decreased.
➢ Preferred reasons for batteries• High power to weight ratio
• High energy efficiency
• Good high temperature performance
• Low self-discharge
ELECTRIC VEHICLES
• Decreasing cost also decreased cost of EVs

➢ Policy changes• US passed Corporate Average Fuel Economy
policy in 1975 which enacted greenhouse gas
emission standards on the transportation industry
• The Energy Policy Act of 2005 offers
companies researching on renewable energy
• The 2009 Omnibus Public Lands Management
Act and the American Reinvestment and Recovery
Act gave 90 billion dollars for green projects

ECONOMIC
POLICIES
➢ EVs make a significant impact in reducing
greenhouse gas emissions
➢ EVs produce less than half of CO2 of
conventional cars
➢ More research is needed on electric vehicles,
➢ US is on the track to make a significant
reduction in emissions
➢ This planet should remain livable for the coming
centuries
