It's a supply and demand issue.
Demand for gasoline is much greater than that for Diesel.
Therefore, the supply of Diesel is less which drives up the price.
Diesel takes longer to burn than gas so, accordingly diesel is more fuel efficient.
Diesel generators are generally more reliable than gas powered ones. Diesel fuel is a bit more cotly than gasoline but oes further.
In small amounts diesel will not affect operation, but eventually as the mixture becomes more diesel than gas it will not burn in a gasoline car, and will damage a diesel vehicle. If you have mixed more than 5% diesel with your gas you should probably drain and start over to avoid damage.
DIESEL is more economical than normal petrol/gas
More BTUs per pound. Taxes.

Diesel generators are more energy efficient, they are more durable and require less maintenance, have a longer life span, and while the cost for diesel is generally higher than gas it costs less to operate a diesel generator because of the fuel efficiency. Just like diesel cars versus gas cars, diesel will last longer. Diesel fuel is a cheaper longer lasting alternative to regualr unleaded gasoline.
Diesel
Diesel gas gives more mileage (miles per gallon) than regular gasoline. You must, of course, have a vehicle that has a diesel engine because diesel fuel cannot be used in an engine that runs on regular gas! Depending on local government taxation policies, in some countries diesel is cheaper to buy than regular gas whilst in other countries it is more expensive! Diesel fuel is thicker and "stickier" than regular gas so, if a vehicle's fuel system ever needs cleaning - fuel tank, fuel lines, fuel pumps and fuel injectors - it is a more difficult and expensive job to do on a diesel vehicle.
Are diesel engines better than gas engines is sort of a yes and no question. Diesel engines generally get better fuel mileage and last longer overall. But, gas engines are easier to maintain on your own and gasoline is much more readily available than diesel fuel is on the whole.

Diesel engines have far more torque or pulling power than gasoline engines. Diesel engines also last much longer than gas engines because they are built to a much higher standard of durability. The downside to a diesel is that they cost more to produce. But for heavy equipment they are necessary and a diesel engine can easily last over 1 million miles.
