As the name suggests, solar lights use solar energy

Solar lights play a major role in conserving the earth as it gets its energy from a naturally available source which is renewable since the sun rises and sets every day without it being depleted. Solar lights are of critical importance in areas where water is scarce as use of solar lights allows the reducing water resources to be used for other critical needs for example for farming instead of it being used as a source of electricity as seen in generation of electricity from water.

Solar lights use energy more efficiently as compared to other types of lights for example as seen in cable type of lighting. Use of energy more efficiently is critical in the face of global warming which has seen the planet experience extreme temperatures with floods, droughts and famines being reported in many parts of the world. Solar lights also do not cause any sort of pollution which is a welcome aspect considering the effects seen with other forms of lights for example those which use coal or thermal energy as their energy source. For personal use solar lights use minimal space in terms of their installation therefore saving on the land needed with the land being freed for other essential uses for example food production.

Use of solar lights saves one quite an amount of money as they use a renewable energy source and therefore do not have to spend money recurrently buying the energy source as seen with other sources of power for example as seen electricity. Solar lights can be used in various places as seen in Outdoor Lighting to light up gardens or paths and can also be used within homes and buildings following proper installations of the materials needed to have them work effectively.
