One of his energy points is Natural gas, not LP, for vehicles. http://www.pickensplan.com/theplan/  this is from the link provided . ..  ..

A cheap new replacement for foreign oil.

The Honda Civic GX Natural Gas Vehicle is the cleanest internal-combustion vehicle in the world according to the EPA.

Natural gas and bio-fuels are the only domestic energy sources used for transportation.

Cleaner

Natural gas is the cleanest transportation fuel available today.

According to the California Energy Commission, critical greenhouse gas emissions from natural gas are 23% lower than diesel and 30% lower than gasoline.

Natural gas vehicles (NGV) are already available and combine top performance with low emissions. The natural gas Honda Civic GX is rated as the cleanest production vehicle in the world.

According to NGVAmerica, there are more than 7 million NGVs in use worldwide, but only 150,000 of those are in the United States.

The EPA estimates that vehicles on the road account for 60% of carbon monoxide pollution and around one-third of hydrocarbon and nitrogen oxide emissions in the United States. As federal and state emissions laws become more stringent, many requirements will be unattainable with conventionally fueled vehicles.

Since natural gas is significantly cleaner than petroleum, NGVs are increasing in popularity. The Ports of Los Angeles and Long Beach recently announced that 16,800 old diesel trucks will be replaced, and half of the new vehicles will run on alternatives such as natural gas.

Cheaper

Natural gas is significantly less expensive than gasoline or diesel. In places like Utah and Oklahoma, prices are less than $1 a gallon. To see fueling stations and costs in your area, check out cngprices.com.

Domestic

Natural gas is our country's second largest energy resource and a vital component of our energy supply. 98% of the natural gas used in the United States is from North America. But 70% of our oil is purchased from foreign nations.

Natural gas is one of the cleanest, safest and most useful forms of energy — residentially, commercially and industrially. The natural gas industry has existed in the United States for over 100 years and continues to grow.

Domestic natural gas reserves are twice that of petroleum. And new discoveries of natural gas and ongoing development of renewable biogas are continually adding to existing reserves.

While it is a cheap, effective and versatile fuel, less than 1% of natural gas is currently used for transportation.
