Issue / Non-renewable Energy

Today, we are largely dependent on the Earth’s non-renewable energy resources. Since the industrial revolution, we have passed successively from one energy source to another: from wood to coal, oil and nuclear energy. Many countries are currently turning toward nuclear power because of predictions that oil reserves will be exhausted within 40 years. However, many believe that nuclear power is not the solution.

All of the power plants in the world today – whether hydroelectric, coal, natural gas or nuclear – are based on the same principle: use of a non-renewable resource to produce steam to drive a turbine connected to an alternator. However, such systems require considerable energy input to produce energy. That is why many say we should turn to renewable forms of energy, including the thermal energy of oceans.
