Alternative & renewable energy solar science fair kits includes wind, solar, hydrogen energy, hydropower and fuel cells. Teachers and Students… see all the new educational alternative and renewable energy science fair kits with curriculum guides. Wind and solar energy are one of the most popular subjects presented at science fairs. They are a preferred source of energy because they are both free natural resources.
Water is a source of energy, but it is not free and we are using up this resource at a rate that may find us in trouble soon. There has been an international committee for many years whose sole purpose is to try to find how to conserve water because our planet's life depends upon it.
Renewable energy (sources) or RES get their energy from natural flows of energy (on-going natural processes), such as flowing water (hydroelectric), sunshine, wind, biological processes and geothermal heat flows.
