Energy question of the week: Bicycles replacing cars - the future of e-mobility?

According to estimates by the German Federal Government, even though today there are few mass-produced electric cars on the market, there will be a million electric cars on German roads by 2020. Despite numerous pilot projects using electric cars, high expectations are being curbed because of high purchase costs, short ranges and a lack of infrastructure for charging stations. On the other hand, sales of two-wheeled electric vehicles such as scooters and bicycles are breaking all records. So is the electric bicycle replacing the car in terms of e-mobility? read more

Will we be driving only electric cars in twenty years' time?

The first, purely electrically-driven compact and sports cars are already on the market, but they are much more expensive than their classic diesel or petrol engine counterparts and have a range of no more than 100 kilometres. Only light, high-performance and cheap lithium-ion batteries will help electric cars achieve a breakthrough. Will such electricity storage devices reach production standard in the near future? read more

Car exhaust gases as a source of electricity?

In cars with internal combustion engines, a large part of the energy stored in diesel or petrol is simply dissipated as lost heat. It is precisely these hot exhaust gases that an increasing number of scientists worldwide want to use for more efficient electricity generation. They are developing and testing thermoelectric generators that can generate electricity from temperature differences of several hundred degrees. But does electricity from hot car exhaust gases really save fuel? read more
