A short thought on electric cars

The electric car is often brought forward as the saviour of the very oil-intensive transport sector. What is seldom mentioned when discussing its benefits is the source of energy. Sure combustion of oil-based fuels emits huge amount of carbon dioxide and other harmful pollutants. But as long as the energy source for an electric car is not sustainable, the benefits are small. Thus, the key here is to make our overall energy system sustainable. To remove natural gas, carbon and oil in electricity generation and instead move towards more sustainable sources, such as solar power, hydro power, wind power and some extent also nuclear power (although its sustainability may be controversial).

That is one of our major challenges for the near future...
