The LIMIT of acceptable Carbon Dioxide emission in our atmosphere has been identified by several groups of experts.
As this LIMIT is approached, climate change 'monsters' will endanger our species.
We must not allow the concentration of CO2 to reach a level which is double the level it was prior to the industrial revolution.
Green capitol investing must be in the Trillions to avoid this doubling of the CO2 concentration.
Thus the experts on carbon mitigation have given us a target to attain.
Avoid the doubling of CO2 by the year 2050.
That is, STOP the emission of some 200,000,000,000 (billion) tons of carbon! We should support ny government initiatives to build electric vehicles.
Recall that we (as taxpayers) now own a big piece of GM! Check out the link below for a video describing an interview with the CEO of Chevrolet Volt! As developing (and developed) countries need to grow, we must avoid getting even close to the doubling of CO2 emissions before 2050.
But what can we do as individuals? Donate the trillion dollars we have in our collective savings? Seriously, lets start at a reasonable level by switching over to Electric Vehicles now.
Do you commute? Do you need to get around your campus or your work area quickly and efficiently? Check out the advantages of an Electric motor bike by using the link below.
What does the required huge global energy commitment look like? The carbon mitigation experts say that beginning now, the world needs to implement 8 or more of the 15 strategies outlined below.
Which 'easy' eight would you choose? One of my choices would be to increase the fuel efficiency of my vehicles.
Consider the miles per charge attainable by some of the available electric motor bikes.

• Increase the fuel efficiency of 2 billion cars to 60 miles per gallon.
  
• Limit the average yearly mileage of cars at 30 mpg to 5000 miles.
  
• Drive 2 billion cars on ethanol.
  This requires one-sixth of the worlds cropland.
  
• Multiply wind power by 80 to make Hydrogen for clean cars.
  
• Multiply wind power by 40 to replace all coal-fired power.
  
• Multiply solar power by 700 to replace all coal-fired power.
  
• Triple global nuclear capacity to replace coal based electricity.
  
• Increase the efficiency of 1600 large coal burning plants by 20%.
  
• Replace 1400 large coal burning plants with natural gas generated power.
  
• Install carbon capture-store technology at 800 large coal burning plants.
  
• Install carbon capture-store technology at 180 coal gasification plants.
  
• Build carbon capture-store coal plants to produce hydrogen for 1.
  5 billion cars.
  
• Stop all cutting and burning of forests.
  
• Adopt world wide conservation tillage to cut CO2 emission from soil.
  
• Cut use of electricity by 25% and carbon emissions by 25%.
  

We wont have much influence on the trillions our government spends unless we set the right example.
For us, the problem is cost effectiveness.
The Grid energy cost for an EV is about 1/6 the cost of gasoline.
