Tesla boss Elon Musk insists transition from fossil fuels to sustainable energy could happen quicker than expected
Billionaire remains optimistic about outcome of the Paris negotiations and says there has been positive movements compared with previous summit in Copenhagen.

The switch from fossil fuels to sustainable energies such as wind and solar is inevitable, and the transition could happen within two decades depending on decisions reached at the Paris climate summit, Tesla Motors CEO Elon Musk said on Wednesday.
Nearly 200 nations are meeting in the French capital for a two-week United Nations climate conference aimed at reaching an agreement to curb global warming caused by carbon emissions which are partly caused by usage of fuels such as coal and oil.
Speaking to students at Paris Sorbonne university campus about climate change, the chief executive of the electric carmaker Tesla, said: “We are going to exit the fossil fuel era. It is inevitable.”
He added that it was no longer a question of if, but when, and governments meeting in Paris could speed the process by reaching an agreement that was not watered-down.
By putting a price on carbon, we are fixing a pricing error in the market
Negotiators from the countries have began working on a draft text of the climate deal this week but many sticky issues are to be resolved.
