What are alternatives to burning fossil fuels for energy?
What is a solar cell made of and how does it turn sun light into energy?(Hour 2 and 7)
Is wind power a reliable source of energy?(Hour2)
How is corn made into ethanol?(Hour 2)
Can garbage be turned into energy?(Hour 7)
This weeks contract asks that you research a specific alternative energy source. Check out previous year's work on Algae, Bug Fuels, and power from water in Tides and Waves. Make improvements to these old pages or research a new alternative energy source.

A solar cell is made of a sandwhich of silicon and other materials. A solar cell converts light energy into electricity when sunlight strikes the cell and makes electrons move from the lower to the upper layer that produces an electric current.
How do solor pannels really work, like I don't get how the sun can go through those pannels and make energy?
in alaska they sould only recomend wind and hydrolecectric because solor would not be a good idea because during the light season whitch the sun is in the sky for 6 mounths stright it would be great but after the light season the dark season comes withch theres no sun for 6 mounths stright you cant use solor because solor requires sun withch the dark season dose not have and thats why solor energy is not good for alaska
A solar cell is made up of silicon and other materials. Solar cells use photovialcs to convert sunlight directly into energy by converting photons into electrons. Photovailcs cells are made of silicon and semiconductors, mixed with other materials. GARBAGE CAN BE USED TO CREATE ENERGY JUST LIKE IN THAT JAPANESE VIDEO WE SAW.
Rachel,
If Stu's answer didn't do it for ya then be sure to ask Maggie this tomorrow.
OLIG!!!!!!!
How do they convert garbage into energy?
Garbage can be turned into energy. You burn it to heat water. The heated water gives off steam which turns a turbine working a generator.
What is a solar cell made of?
Stew(Stuart), how is an electrical current affiliated with solar cells. Alcohol is an energy alternative. Alcohol can be used in different forms, like ethanol, to be used as an energy source.
Garbage can be burned and turned into warmth this can can be turned into others things to it is changed into energy
