Nuclear Comes from an atom called uranium The atom is split and produces energy 20% of US energy is from Nuclear Power It produces radioactive waste. There is a lot of it.

Hydropower It comes from water. Goes through a dam and turns a turbine that produces electricity. 3.3% of the US energy comes from hydro power It is renewable. Causes floods and creates problems for animal life.

Wind Wind is from the uneven heating of the earth. Wind can be changed to electricity from turbines. 3% of us electricity comes from wind power. Kills birds and takes up more land. It is renewable

Solar Comes from the sun. Goes through a solar panel which turns the heat into electricity 1% of US energy comes from Solar energy It is very expensive to capture solar energy in panels. It is renewable.

Geothermal It comes from inside the earth. Cold water is put down to heat section and steam rises that turns a turbine that creates electricity. 0.4 % of us electricity comes from geothermal energy. It is very dangerous and hard to collect. It is renewable.

Fossil fuels It comes from dead plants and animals that died millions of years ago. It is changed into electricity in a refinery. 81% of us electricity comes from fossil fuels. It is nonrenewable and takes millions of years to form. We have a lot of it.

Biomass Made out of natural waste. It is burned to create electricity. 4% of us energy comes biomass. Very few refineries Renewable

Energy transformation How any type of energy is changed into electricity.

Experiment 1

Experiment 2

Conclusions I found that all of the experiments were successful The solar power experiment took 3 tries before it worked. The wind power experiment did work the first time.
