Solar Engergy by Irina, Kira and Sophia Z. (CM2-A)


Solar Energy
Solar energy is radiant light and heat from the sun. It is a renewable energy source, and it is collected with solar panels and becomes solar power. The solar power is the conversion from the sunlight into electricity that can be used for many things. It doesn’t give off carbon dioxide emissions. It is a power that won’t run out.
So how can people turn those sun beams into useful electricity? :
Sunlight contains energy. Usually, when light hits an object the energy turns into heat, like the warmth that you feel while sitting in the sun. But when the energy of the light hits a tin can the energy turns into an electrical current instead, which we then use for power.
Before we didn’t know the effects of pollution were so serious, but now we are finding solutions like the use of solar power and reducing deforestation.  We need to apply these solutions more: We still don’t use solar power everywhere because people say it’s too expensive. But what is the real cost if we don’t?
The end
