Why do we need alternative energy?
Because alternative energy can be used in SO MANY different ways that we would need! Transportation, health, and more!!!
These are solar panels. Solar panels are devices that convert light into electricity. They are called "solar" panels because most of the time, the most powerful source of light available is the Sun.
The sun is the main source of energy for solar panels.
Wood is a typical source of biomass.
Carbon dioxide comes from many different things ran by energy ad the carbon dioxide goes to the sun. The sun is solar energy. Solar energy+Carbon Dioxide=BIOMASS!!!!!
Water from lakes or streams is put into a dam and it's being produced to make hydroelectric energy.
This is an example of the making of hydroelectric energy.
The wind moves these windmills, and the more the windmills move, the more energy is made.
The stronger the wind blows, the more energy we have.
