According to the Union of Concerned Scientists(UCS), Biomass is a kind of renewaBle energy source that produces no carBon dioxide , Because the energy it contains comes from the sun. When plant matter is Burned, it gives off the sun's energy. In this way, Biomass serves as a sort of natural Battery for storing the sun's energy. As long as Biomass is produced continuously ----with only as much grown as is used--- the "Battery" lasts forever. According to the Energy Information Administration, Biomass has Been one of the leading renewaBle energy sources in the United States for several years running through 2007, making up Between 0.5 and 0.9 percent of the nation's total electricity supply.

Apollo 11, carrying Neil Armstrong, Edwin Aldrin and Michael Collins, was launched on 16 July, 1969. Five days later they stepped down onto the moon. Neil Armstrong On the way there: Of all the wonderful views we had, the most impressive to me was on the way to the Moon when we flew through its shadow. We were still thousands of miles away, but close enough so that the Moon almost filled our window. The moon appeared blue-grey. It seemed almost as if it were showing us its roundness, its similarity in shape to our Earth, in a sort of welcome. I was sure it would be a hospitable host. It had been waiting for its first visitors for a long time. After touch down: The sky is black, you know. It's a very dark sky, but it still seemed more like daylight than darkness as we looked out the window. It's a very strange thing but the surface looked very warm and inviting. It seemed to be tan . It's hard to explain that, because later when I held the material in my hand, it wasn't tan at all. It was black, grey and so on. Edwin Aldrin On the Moon: The blue color of my boots has completely disappeared now into this soil--still don't know what color to describe this other than grayish cocoa. Back on board: The moon was a very natural and pleasant environment in which to work. On the Moon, in one-sixth gravity, you have a strong feeling of being somewhere. As we did our experiments, some objects we threw away would go in a slow, lazy manner. What did Armstrong find very strange on the moon? A) The color of the sky. B) The surface of the moon C) The gravity on the moon. D) The daylight on the moon.
