Three crucial factors make the changeover to renewable fuels more urgent than ever:
Climate change
Our use of fossil fuels contributes to global warming which, in the long term, will certainly have dramatic and unpredictable consequences for life on Earth.
Increased energy demand
Rapid economic development in populous countries, such as India and China, is increasing the pressure on the crude oil market, which is now at the limit of its production and refining capacity.
Decline in finite resources
The Earth’s reserves of oil and other fossil fuels will eventually be exhausted – the only question is when – and some observers believe that oil production has already peaked. The price of oil will increase in the long term and will also become unstable due to geopolitical factors.
