What is the challenge of using alternate fuels?

The challenge is to educate the public and politicians that alternative fuels (renewable energy (solar, wind, hydro, tidal and wave, geothermal and biofuel)) are better for the environment.
Alternative energy power plants are also expensive to establish in their first year, and this blinds people to the fact that for all the following years the energy is practically free.
