They are sometimes called alternative energy sourcesbecause they are not the ones used now. (Yet!)
what is origin of non-renewable energy sources, including how energy became trapped in these souces
The most popular renewable energy sources currently are: Solar energy. Wind energy. Hydro energy. Tidal energy. Geothermal energy. Biomass energy.
Wind energy and solar energy are called renewable energy sources. Other renewable energy sources include hydroelectricity (generated by water movement) and geothermal energy.
renewable source of energy can be regenerated but non-renewable source of energy can not be regenerated.
Renewable energy sources are Solar, wind, Geothermal, Tidal are prime energy sources
They are called renewables. (though strictly, nuclear power is not a fossil fuel and is not renewable).They are called alternative energy sources.
some energy sources are non renewable but some are renewable
Renewable energy resources are always there. We just need to harness them.
it is renewable and it is available throught the world
Yes, a wind turbine is a renewable energy source!!
Because if we use renewable sources, it's with us forever. fossil fuels and non-renewable sources will run out someday.
Electricity is a secondary power source. It depends on what is used to generate it. Wind, water or solar are all renewable or use little or nothing after the original manufacture of the component's.
