__**Ladies and Gentlemen, we have a problem**__


 * The Issue At Hand**: We are experiencing global warming at unparalled rates. We have a huge problem with climate change which is caused by us using non-renewable fuels which pollute the environment and make more ozone and smog which traps gases we emit.


 * Stupendous Solution:** Tidal energy is free after being installed and is extremely predictable. Tidal energy from Tidal Barrages, which trap the tide and then let it back out, making the rushing water spin a turbine which generates energy.


 * Evidence: The Issue:** We know that there is an issue with climate change because we have ice core data that goes back over 400 thousand years, showing that once we started using more fossil fuels, carbon dioxide and methane levels have increased dramatically since we started using fossil fuels. We also have evidence of this from Mr. Keeling's data gathered on top of Mnt. Mauna Loa.


 * Evidence: The Solution:** Tidal energy is known to generate about ten hours a day, as the tide goes out. Tidal turbines have a very efficient design that allows for maximum energy production. The turbines are somewhat expensive to install, but have one of the fastest repayment rates in the alternate energy universe. Tidal energy has no pollutant side effects because no part of the process of gathering energy from the sea requires fossil fuels. Currents are regular, so energy is predictable, unlike with solar and wind energy. This means that tidal energy can be counted on to help create energy. Tides come in and out with huge force, more than many people realize. When a tide goes out it drags away with huge power which spins turbines to create a substantial amount of energy to be consumed in any way needed.
