Solar energy is radiant light and heat from the Sun that is harnessed using a range of ever-evolving technologies such as solar heating, photovoltaics, solar thermal energy, solar architecture, molten salt power plants and artificial photosynthesis.
2. What is Solar Energy?
• 1. Energy produced by the sun
• 2. Clean and renewable source of
energy
• 3. Solar energy captured with
various technologies, primarily
solar panels
• 4. Converted into usable energy
such as electricity
3. Environmental
Impacts
The sun provides a tremendous
resource for generating clean
and sustainable electricity
without toxic pollution or
global warming emissions.
1. reduction of CO2 emissions
2. improvement of the quality of water
supplies
3. reclamation of degraded land
4. reduction of the number of the required
power transmission lines

5. So, why solar power?
• The main advantage is that it is a renewable, clean source of
electricity. Solar power is also scalable. When it's used on a small
scale, extra electricity can be stored in a battery or fed back into the
electricity grid. Overall, the sun gives off far more energy than we'll
ever need.
• Solar power doesn't release any greenhouse gasses, and except for
needing a source of clean water to function, it uses absolutely no
other resources.
6. Conclusion
• Sun provides power only during the day is countered by the
fact that 70% of energy demand is during daytime hours. At
night, traditional methods can be used to generate
electricity.
• The goal is the decrease our dependence on fossil fuels.
• Currently, 75% of our electrical power is generated by coal-
burning and nuclear power plants.
• Pollution-free, indefinitely sustainable.
