Fuel cell is worthy of notice other alternative energy.
It generates electricity inside a cell through reactions between a fuel and an oxidant, triggered in the presence of an electrolyte.
Fuel cells are direct energy conversion into electricity. So High electric conversion efficiency and carbon dioxide reduction is excellent.
Since 1999, A joint research for 2 years

variety form and high efficiency are possible because components are solid
of chemical energy to electrical energy is more efficient and generates much less pollutions than do traditional methods that rely on combustion.
Fuel Cell Functionality
Fuel cells generate electricity from a simple electrochemical reaction in which an oxidizer, typically oxygen from air, and a fuel, typically hydrogen, combine to form a product, which is water for the typical fuel cell.

About state governments, they give tax incentives for hybrid vehicles. Toyota use them for selling the Prius.
About companies, Considering the fact that employees of certain companies can cash in , Toyota sell its product, the Prius.
