Because all those energy sources are natural and will always be there, when ever there is a need for extra energy.
Explanation:
Wind, solar, and biomass energy are all sorts of renewable energy. Wind and solar energy use do not apply a natural resource as is the case with coal and oil use. Using renewable maintenance is a sustainable method because it allows for extensive energy use. Coal and oil supplies will eventually be exhausted behind the energy demands of the population because they are nonrenewable resources. Wind, solar, and biomass energy, on the other hand, can meet modern energy needs and maintain to meet the energy needs of the prospect.
