धरती को बचाने की कोशिश

Scientists are working very hard on developing new ways to use clean energy sources which come from renewable resources - like wind power and direct solar energy from the sun. Approximately every 40 minutes the sun sends as much energy to Earth as all the people on Earth use in a year! But, we have to get industry to make more products that use the safe environmentally-friendly energy, like solar-powered vehicles, and at a price people can afford. Other technologies, such as fuel cells, are under development to provide energy sources that minimally harm the environment. People need to change their thinking and refuse products that damage the environment.
