1. How the waste of energy affects the environment ?
**Susana Cordoba, 16 may 2011**


 *  SYNTHESIS **


 * The use of energy have a big of impact on the environment. **


 * The ice of the poles are melting, there is global warming and a lot of water is wasted for making energy. **


 * Some of the energy is made by fossil fuels, by now there are enough fossil fuels to give energy for everyone, but they can finish, and the extracting of it also have an impact on the environment. If we keep using it like we are now, it would be gone and it would be gone for ever. **

**Burning fossil fuels cause:**
 * Impacts: **
 * ** Carbon dioxide is a greenhouse gas and a it cause global warming. **
 * ** SO2 causes acid rain, this is dangerous to plants and to animals that live in water, it also cause respiratory illnesses and heart diseases, mostly in children and in old people. **
 * **NOX increase the ground level and the ozone layer get damage, this damage the lungs. **
 * ** PM causes cloudy conditions in cites, the ozone layer damages, asthma and chronic bronchitis, especially in children and in old people is caused. It also cause emphysema and lung cancer. **
 * ** Heavy metals such as mercury can be dangerous to human and animal health. **

Making a car, for example, creates 5.22 tonnes of carbon dioxide (CO2) — a greenhouse gas that pollutes the environment and leads to climate change. Of course, using gas and oil to run the car creates even more.

Humans need energy for cooking, heating, for transportation and more. Our lives depend on it. But it is very difficult to create energy without having a big impact on the environment, because just the extracting of the resources for energy like coal can have a impact on environment.

Save energy ==== Our waste of energy affects the environment because the energy is made by fossil fuels, by now there are enough fossil fuels to provide energy for everyone, but they are not an endless supply. If we keep using it like we are now, it would be gone and it would be gone for ever. but if we use less energy, oil, coal, and gass it will last longer. Possible solutions: We could use water, sun, and wind energy that do not produce Carbon dioxide when they are turned into electricity, and it is a renewable energy. ==== We could use solar panels as solar energy. We could use wind turbine as wind energy. We could use Tides ( Variations in the water surface), Dams(picture 1), Water falls, and Tidal barrages( when sea meets with a river). (BOOK: save energy)

Prior knowledge

The use of energy has a lot of impact on the environment like the ice of the poles are melting, there is global warming and a lot of water is wasted for making energy.
