Many other electric cars and hybrids (which use both fossil fuels and electricity) are in production already or are in various stages of design. As more manufacturers enter the electric/ hybrid space, prices will reduce and technology will improve. However, while consumers are clearly ready to go electric, the ecosystem is rudimentary in most places outside Southern California. Charging, for example, is cumbersome; it takes hours from a standard wall connection. Tesla's revolutionary Supercharger Connectors shorten charging to an average of 40 minutes, which is still a lot longer than it takes to fill a sports utility vehicle's diesel tank. Nor is there a global network of "charge pumps", and there aren't standardised tariffs for charging either. The market can certainly take care of most of these challenges. The charging networks will likely develop as electric vehicles become popular. But early adopters may have to resort to carrying an extra battery set in the trunk on long commutes.
It would also be wrong to assume that an electric vehicle is automatically good for the environment. It depends on the energy mix used in generating power. That varies from nation to nation. India for example, generates about 70 per cent of its electricity from thermal coal, which has a larger carbon footprint than petroleum or natural gas. So an electric vehicle may actually be worse for the environment in India. However, the power industry has incentive to go green and indeed, the charge networks of the future are likely to be green.
Despite all these caveats, the Model 3 could be a game changer. If the demand for electric vehicles is this strong, every auto major will get on board. That should lead to a rapid development of electric car technologies and the associated ecosystems with all the benefits that scale can generate.
