Final Draft Solar Energy: Powering Our Future Today nearly half of the world’s energy is provided by petroleum. What began as a cheap and abundant way to provide energy‚ has become expensive‚ environmentally harmful‚ and finite. With population explosions and the demands of modern lifestyles‚ the world’s need for energy production has become far too much for fossil fuels to keep up with. Experts say that the Earth’s stores of petroleum will be depleted by 2050

This can happen only at new moon‚ when the Sun and the Moon are in conjunction as seen from Earth. In a total eclipse‚ the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses only part of the Sun is obscured.If the Moon were in a circular orbit close enough to the Earth and in the same orbital plane‚ there would be total solar eclipses every

Paper Princess Erin Watt‚“ Besides his sperm my father’s watch was the only thing he left behind” (chapter 1). This line was an absolute favorite of mine. It could be interpreted in so many different ways. Her tone could be bitter‚ feeling as if the man she she was supposed to call father only cared enough to just leave her a lousy watch. Or maybe she means to have a playful tone‚ laughing at the fact that he was so inconsiderate and that he doesn’t deserve any hateful feelings she has to offer.

Introduction "A "light bulb" now exists that does not use any conventional energy. Introducing the Solar Bottle Bulb -- an alternative source of daylight powered by the sun. It is made from an old soda bottle. By filling it with water and sealing it into the roof‚ the water refracts the sun’s rays and provides about 55 watts of light to a darkened room. This was invented in 2006 by students at the Massachusetts Institute of Technology (MIT). It can be built and installed in less than 1 hour
