100 years ago when the first cars were invented and the fuel source for the model T was chosen, alternative energy sources such as solar, steam, and wind were considered to power them. At the time it was cheaper to use oil, so they stuck to that. Now one hundred years later, we are facing a huge global warming problem and co2 emmisions are a huge part of the problem.

Here is how we solve the problem:

-change our national average mpg for cars to 50+ mpg and require them to be powered by alternative sources or be a gas hybrid.

-Switch all public transportation to be 100% free from oil, and to use solar wind, and electricity.

-Power trucks with 100% american natural gas (since it is the only source that can produce the best mpg) And use trains more to move goods across the country.

-Provide tax breaks for fuel efficient american cars, and tax car owners that own in-efficient SUVs and cars that further guzzle gasoline. Also provide a tax break for americans that buy and pay for these vehicles for 10 years, or until they do not own the car.

- Create a $1 tax on gasoline that pays for transportation projects, subsudies for small car companies that create efficient cars, and to pay for infrastructure projects.

-Work with China, and India and other immerging countries to buy efficient American cars, and to switch to using non gasoline cars.
