Hybrids Advantages include: Unlimited miles Great mileage in city driving Average fuel savings of 25%, ($600/yr)
Disadvantages might include: Higher initial cost ($3-4000) Only smaller vehicles currently No advantage (MPG) at highway speeds Battery life, four years for lead/acid batteries Cost of battery replacement ($2000) NiMH cost $20,000-30,000 Service availability Crash danger of 20 lead/acid batteries
Battery Problems You can replace lead-acid batteries with NiMH batteries. The range of the car will double and the batteries will last 10 years (thousands of charge/discharge cycles), but the cost of the batteries today is 10 to 15 times greater than lead-acid. In other words, an NiMH battery pack will cost $20,000 to $30,000 (today) instead of $2,000. Prices for advanced batteries fall as they become mainstream, so over the next several years it is likely that NiMH and lithium-ion battery packs will become competitive with lead-acid battery prices. Electric cars will have significantly better range at that point. NiMH = Nickel-metal hydride battery
Battery manufacturing Lead mined in Canada Shipped to China for manufacture Shipped to US for sale The “carbon footprint” in the manufacture and shipping of these (20) lead/acid batteries is equivalent to 3 ½ years of driving with a gasoline vehicle. Recycling these batteries costs up to $2000/ton
Crashes with electric/hybrid? Firefighters and rescue personnel receive special training to deal with the higher voltages and chemicals encountered in electric and hybrid electric vehicle accidents. While BEV accidents may present unusual problems, such as fires and fumes resulting from rapid battery discharge, there is apparently no available information regarding whether they are inherently more or less dangerous than gasoline or diesel internal combustion vehicles which carry flammable fuels.Firefighters

EVs Great variation in style and cost. Limitations include distance. New batteries will help here, but at substantial increased costs. Recharging at work. Electricity is not free energy. Usually small commuter vehicles http://en.wikipedia.org/wiki/Electric_car
Flex-fuel vehicles These vehicles are designed to run on a variation of different fuels. Ethanol fuels now are 90% unleaded gas and 10% ethanol. Flex-fuel vehicles allow for up to 85% ethanol. These include different sensors in the vehicle to deal with variations in fuels.
Fuel savings? FFVs experience no loss in performance when operating on E85. However, since a gallon of ethanol contains less energy than a gallon of gasoline, FFVs typically get about 20-30% fewer miles per gallon when fueled with E85. http://en.wikipedia.org/wiki/Flexible- fuel_vehiclehttp://en.wikipedia.org/wiki/Flexible- fuel_vehicle
Biogasoline/synthetic gas Unlike ethanol, the fuel can also be used in high concentrations in regular gasoline engines and travel through existing pipelines, the companies said. In addition, it will have a higher energy content and be more fuel efficient than ethanol, the leading renewable fuel in the U.S. today, the companies said.
Hydrogen fuel cell These cells are expensive storage units. Batteries if you please. Recharging them is a major problem (at present) Adding filling stations would cost 1/2trillion dollars. (US) Still run an electric motor.
Diesel vehicles Diesel vehicles have several advantages: More power Better MPG, (20-30%) Longer life Better resale value Burn almost any type fuel oil
Higher compression Up to 20:1 compression ratio increases the power proportionately
Diesel Disadvantages include: Higher initial cost ($5,000) Higher fuel cost (20% more) Heavier vehicle to support the heavier engine Fuel availability
Diesel? In addition to improved fuel economy, diesels offer other benefits. Compared to gasoline engines, diesel engines produce 20 to 30 percent less CO2 emissions, which contribute to climate change. And turbocharged diesel engines produce far more torque than gasoline engines, making them fun to drive and well-suited to tasks like towing.
Why is Diesel so costly? Highway Diesel Fuel 500 ppm: Sulfur limit of 500 ppm = 0.05% (wt.) became effective in October 1993. This fuel, commonly referred to as the low sulfur diesel fuel, was introduced to facilitate sulfate particulate emission reductions, which were necessary for meeting the 1994 emission standards for heavy-duty highway engines. 15 ppm: Diesel fuel of maximum sulfur level of 15 ppm will be available for highway use beginning in June 2006. This fuel, referred to as the ultra low sulfur diesel (ULSD), was legislated by the EPA to enable catalyst-based emission control devices, such as diesel particulate filters and NOx adsorbers, which will be necessary for meeting the 2007-2010 emission standards for heavy-duty engines, as well as the Tier 2 light-duty standards.
Other choices Walking Bicycling Mopeds Roller blades Motorcycles. All these have advantages of energy savings and ease of parking.
Back to driving more fuel efficiently We have talked about selection –Buy fuel efficient vehicles –Buy what meets your needs –Doing your homework
Driving more fuel efficiently Accelerate slower
Drive at moderate speeds 45 MPH is optimum for fuel economy.
Prices of gas around the world Prices are quoted in US dollars per gallon for regular unleaded. March 2008 US ($3.25) Oslo, Norway $6.82 Hong Kong $6.25
Brussels, Belgium $6.16 London, UK $5.96 Rome, Italy $5.80
Tokyo, Japan $5.25 Sao Paulo, Brazil $4.42 New Delhi, India $3.71
Sidney, Australia $3.42 Johannesburg, South Africa $3.39 Mexico City $2.22
Buenos Aires, Argentina $2.09 Riyadh, Saudi Arabia $0.91 Kuwait $0.78

Fuel costs Energy cost is becoming an even more difficult problem for all of us. Your government (despite commercials), is not trying to lower fuel costs. Their goal is for us to use less, therefore, higher prices help meet their goal. We used 1% less gas last year (2007). That percentage will be higher this year as prices go to $4/gallon. That is successful! (To your legislature)
You are on your own! It is your responsibility to reduce your fuel and other energy costs. Select a better vehicle (MPG) Drive more fuel efficiently Drive less, carpool, combine trips, etc Plan your vehicle use better You will spend thousands of dollars this year on gas, a 10% savings is significant.
