Not good for the environment, peace, or your health but off the charts good in terms of energy density.
Gasoline has an energy density of 12 kWh/kg although that is a little misleading because internal combustion engines only have about 20% thermal efficiency. Sill that means about 2.5 kWh/kg or 2,500 Wh/kg of usable energy. A lithium-ion battery while having 5x the energy density of Lead Acid batteries only has about 150 Wh/kg.
It is a cruel irony that oil was "so good". It blinded the human race for a century and stifled innovation. Everyone knows about GM's first electric car but this one made by Detroit Electric was made in 1916 but alas oil was just too good. Maybe Tesla can make good on that potential just over a century later.
