Our world is in the midst of an energy crisis, and the energy we are using is polluting our world. The fossil fuels we use for our energy is a colossal contributor to the factor of global warming. The fossil fuels we burn produce green house gasses, which the earth does need to keep it's stability in warm temperatures, but the excessive amount of green house gasses is causing the world to be abnormally warm. Not only is our source of energy and fuel limited and very close to its expiry, but our world is becoming extremely over polluted because of it. There is a solution though, by using re-newable, ecofriendly energy sources. The five main renewable energy sources is geothermal energy, wind energy, hydrpowered energy, biomass energy and solar energy. The only problem is the materials to produce these re-newable energy sources are finite. Like the metal to make the wind turbines for the wind powered energy. BUT by switching to these renewable sources we can buy ourselves time and look for another source of energy that is 100% renewable (meaning the materials are renewable) while making the world less polluted.

__** My 3 publishing technologies: **__ Picasa: Talks about the 5 energy sources, how they work and why we need them. Prezi: Will discuss how fossil fuels are limited and how they pollute our world and how we need these renewable sources. Glog: Will talk about why we should and need to quickly change to alternative fuel sources. Wordle: Talks about what will happen to earth if we don't change the way we consume energy.
