Future and alternative sources of energy

It is possible that the world is heading towards a global energy crisis due to a decline in the availability of cheap oil and recommendations to a decreasing dependency on fossil fuel. This has led to increasing interest in alternate power/fuel research such as fuel cell technology, hydrogen fuel, biomethanol, biodiesel, Karrick process, solar energy, geothermal energy, tidal energy and wind energy , and fusion energy. To date, only hydroelectricity and nuclear power have been significant alternatives to fossil fuel (see Future energy development), with big ecological problems (residues and water spending). Hydrogen gas is currently produced at a net energy loss from natural gas, which is also experiencing declining production in North America and elsewhere. When not produced from natural gas, hydrogen still needs another source of energy to create it, also at a loss during the process. This has led to hydrogen being regarded as a
