1. Tidal Power Ray Mik and Joe

2. Tidal Power : What is it? A huge dam called a barrage is built across a river. When the tide goes in and out, the water flows through tunnels in the dam which have turbines inside.

4. Another form of tidal power are giant turbines underwater that look like wind turbines. The tides flow and make the wings on the turbines spin which cause electricity.

6. Pros/cons 1. Environmental: con-restrict wild life from migrating. Pro- doesn’t spill gas, oil or toxic liquids into ocean. 2. Cost: tidal energy projects using dams require a stop and start process with the tides. Tidal dams produce less than half the electricity of a non dam tidal energy product. Eventually the US is going to need to be more dependant on domestic energy resources, and this is a good one because it is domestic and we have good access to it.

13. Active Solar heating Big windows on the side of the house Big windows on the side of the house Creates and captures heat by having the sun come into the windows and heat up water. Creates and captures heat by having the sun come into the windows and heat up water. This is a good way of capturing heat and also having a good view outside This is a good way of capturing heat and also having a good view outside

14. Solar panels Panels consist of solar cells Panels can range from 10 to 300 watts Very good for environment n no toxic waste or pollution to create electricity

15. Rain barrels 1. Free water 2. Good for the environment, not wasting water 3. Plants grow better with rainwater 4. Also conserving water because your not watering the plants with new water
