Alternative Energy: Is a Solution to the Climate Problem?

Abstract

The world is doing many efforts to mitigate climate change, researching and developing various sources of the renewable energy such as wind, photovoltaic, solar, tidal, geothermal, aero thermal, bioenergy, undimotriz or hydropower.This leads us to consider for the moment, as it indicates, are alternative energy, namely, they not yet ready to be a substitute for fossil fuels and for the time being complementary energy from fossil fuels. At this time, these energies can not make the various societies to abandon the use of petroleum and its derivatives as energy. We in this chapter we will try to address not a source of renewable primary energy, but an energy vector, the hydrogen. This, in the future may be the replacement of fossil fuels.However, despite the efforts of some countries, we are still far from turning the hydrogen energy future, and being the main energy source that solve our energy problems and climate change.
