Hydrogen power has been on the drawing board for decades, and many carmakers have hydrogen-powered prototypes showcasing the eco-friendly technology. Hydrogen is, in theory, an ideal fuel source: It's the most abundant element on Earth; it generates power when it combines with readily available oxygen in the atmosphere; and the only byproducts of the reaction are water and heat.

Going back to school and going green can go hand in hand! Kids can get green school supplies that will make a difference at prices that will make mom happy. Your green school supplies also provide an opportunity to share your thoughts on the environment with other students and teachers who notice that they are a little different.

Less carbon emissions and less smog comes from less burned fuel. We have to use gasoline to run most of today's cars - so, let's use as little of it as we can! When you share a ride with others, it means fewer people have to use gas, and when you walk or bike there is no fuel burned at all...except maybe your breakfast ;-)

Most people let the water run while soaping up or brushing, but that wastes water. Run the water to get your towel and body or toothbrush wet, and then wash or brush with the water off. It saves water AND time because you end up focusing on getting clean and getting out of there!

It's a large undertaking, but if you can get your science teacher behind you, it's very likely that your principal will allow you to start an organic garden of some kind and a compost heap to fertilize it. Learn about composting for kids here, and get your science teacher to help you learn about gardening. You're sure to get extra credit!

Kids who aren't environmentally conscious don't usually think about turning off lights and appliances because kids in general aren't cost conscious. That means kids waste stuff. (Don't worry - your parents did it when they were kids, too.) Kids who reduce, reuse, and recycle know that wastefulness is not good, and one thing they do not waste is energy. Although cleaner energy is becoming more common, no energy should be wasted. When you're not using lights or appliances/electronics (TV, computer, video games, etc.) TURN THEM OFF! Let mom and dad unplug them from the outlets as they see fit for safety.

The family that recycles together stays together! If mom and dad recycle, ask them if you can sort if you already don't. Sometimes parents don't realize how much you care. Going green is a lifestyle, so get in on the day-today activities by doing your part.

Trees help us enjoy cleaner air and more beautiful landscapes. Get help finding organizations where you live who plant trees, and then volunteer to help! The Arbor Day Foundation is a good place to start if you need help locating a group in your local area.

Most people don't realize it, but dishwashers use considerably more water to wash a load of dishes than the traditional sink method does. A LOT MORE. So, to conserve water, it's best not to use the dishwasher at all. If you do, use eco-friendly dishwashing detergent and only run the washer when it is completely full. If it's not full or if you can, choose to wash dishes in the sink instead, of course, with eco-friendly dishwashing liquid.

It's easy to use throwaway cups, plates, wrappers, and utensils, but it only creates more waste for landfills. Also, disposable paper products like facial and bathroom tissue and paper towels and napkins also end up in the trash. We can save more trees by using less paper products, and we can keep more plastics and styrofoam out of the landfills by using less throwaway utensils and containers. Also, eating less often at fast-food restaurants cuts down on your useage of these items, too.

Playing video cames on both computers and systems uses a LOT of energy! That's why your system or computer feels hot afterwards! You can save on energy by simply doing homework or going outside to play instead of posting up in front of the TV or comsputer screen. This activity uses more electricity than regular TV or computer useage, so it should be kept to a minimum.
