Solar energy is a potential solution to the environmental problems being caused by fossil fuels. When fossil fuels are burned to generate electricity, they release harmful greenhouse gases into the atmosphere. The vast majority of scientists believe that continuing to depend on fossil fuels is going to cause serious environmental problems in the future.

Another important use for solar energy is in satellites. Many satellites are engineered with photovoltaic panels, which capture sunlight and convert it into electricity that is used to power the satellite. Solar power is also useful in areas where standard electricity is not available. For example, research facilities in Antarctica depend on sustainable energy sources, such as the sun and wind turbines, to generate power.

Emergency phone systems in remote places often use solar power as a dependable power source. Solar energy can also be used to power devices that run at night. For example, some streetlights are able to charge energy from the sun during the day, then run throughout the night.
