Going+Green

In the past 10 years, new light has been brought to global warming and the Ozone layer. The need to cut emissions and save energy became very apparent and many Americans and companies have "gone green." Also the need for renewable energy as opposed to non-renewable energy is a major focus for the companies of America. Car companies have made some of the biggest changes, with hybrid cars to lower gas emissions and get more gas per mile. But the need to not be so independent on gas and coal and oil have been a big challenge of the American people and their companies. Scientists have been working on using other products as fuels, like vegtable oil, bioalcohol, methane, and even water.
