The Sun has the potential to meet all our energy needs, if only we could harness it efficiently. Why is it so difficult to efficiently convert and store this energy?
- The Sun provides solar energy.
- Sunlight can be used indirectly when converted to electricity, or directly used to heat water.
- Photovoltaic cells convert solar radiation into a usable electrical current.
- Solar power can be expensive and inefficient, but solar panels are long lasting and require little maintenance.
