2. Facts Renewable energy Has been being harnessed by humans since ancient times Can be used to heat water, heating cooling and ventilation, air conditioner, water treatment, cooking and transportation.

3. How its used Solar chemical processes use solar energy to drive chemical reactions. These processes offset energy that would otherwise come from a fossil fuel source and can also convert solar energy into storable and transportable fuels.

4. storage Solar energy is not available at night, and energy storage is an important issue because modern energy systems usually assume continuous availability of energy. Off-grid PV systems have traditionally used rechargeable batteries to store excess electricity.
