You can't overcome them! The main disadvantage of coal is that it is a non-renewable fossil fuel. Therefore it will run out in the future. We need to find viable alternative energy sources.
Natural gas has long been considered an alternative fuel source to that of conventional petroleum fuel sources.
someday we will eventually run out so we nedd alternative resources for fuel
They are called renewables. (though strictly, nuclear power is not a fossil fuel and is not renewable).They are called alternative energy sources.
energy
an alternative to electric like solar power
the instrument are costly Only makes power when sun is out.
Common ' alternative ' fuel sources. The one listed below are quite easy to create on a small and large scale. Wind Power Solar Powar Biomass (methane, ethanol) Mirco Hydroelectric
The answer depends on how to define alternative energy sources.Alternative energy sources may be typically and interchangeably for renewable energy sources.If this is the case then the five energy sources used as alternative are:Solar,Wind,Biomass,wave, andTidal alternate energy sourcesAlternative energy sources may be defined as sources of usable energy intended to replace fuel sources without undesired consequences of replaced fuels Typically excluding fossil fuels and nuclear energy). If this is the case then the five energy sources used as alternative are:Coal as alternative to wood,Petroleum as alternative to whale oil,Alcohol as alternative to fossil fuel,Coal gasification as alternative to expensive petroleum, andRenewable energy as alternative to nonrenewable energy.For more details it may be referred to:http:/en.wikipedia.org/wiki/Alternative_energy
Alternative energy
One of the largest benefits of alternative energy cars is the reduced maintenance costs associated with moving away from traditional fossil fuel powered vehicles. Gasoline, by its very nature, is a dirty and heat intense power source; this results in great deals of friction and wear on engine parts. Alternative fuel sources are less wear intensive, resulting in fewer repair and maintenance costs.
