Many of the Pokmon within the Dream World will have abilities that the Pokmon you transfer over from Diamond, Pearl, Platinum, HeartGold & SoulSilver don't normally have, such as Vaporeon with Hydration and Glaceon with Ice Body. A few are also available in-game and others through events.
Hybrid cars have smaller, more efficient internal combustion engines than conventional vehicles because the electric motor provides additional power when needed. The smaller engines produce less pollution. Gasoline engines in hybrids automatically shut off when stopped and restart when the accelerator is pressed.
Hybrid and electric cars do not help the environment They still need things like copper, steel, lithium, graphite, cobalt, glass and plastics. These things all need raw materials to be mined, refined, processed and transported. They need roads, and infrastructure to charge them or supply them with power.
