We have to admit: there are indeed other ways to produce and use energy without damaging the environment. But these environmental-friendly solutions are often premature and too expensive. Even the facilities are not always the best.
Let's take the electric cars as examples. With one charging, we can use them the whole day, driving to work and back home. But for a longer use, we have to charge them during the day. And this charging happens at charging stations and it takes hours. In addition, many of these cars have different chargers, like the Nissan Leaf or the Chevrolet Volt.
It would be more easier to charge the vehicle at home, however, for that we need a SAE J1772 standard for the 120 Volt plugin at home. Some of the cars, like the Nissan, is already designed for this solution.
However, battery charged cars are still a bit early for our society. Not everybody can afford it and the charging time is also not the best.
