Advantages of and Problems with Solar Energy by Ethan Goffman I’d put my money on the sun and solar energy. What a source of power! I hope we don’t have to wait until oil and coal run out before we tackle that. – Thomas Alva Edison‚ 1931 The oil embargo of the 1970s prompted a national surge of interest in solar energy. A solar water heater was installed in the White House‚ and photovoltaic panels first came into play‚ notably in California. While previously solar power as a direct source of electricity

has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat water — for

Solar System Our solar neighborhood is an exciting place. The Solar System is full of planets‚ moons‚ asteroids‚ comets‚ minor planets‚ and many other exciting objects. Learn about Io‚ the explosive moon that orbits the planet Jupiter‚ or explore the gigantic canyons and deserts on Mars. How Did The Solar System form? This is an important question‚ and one that is difficult for scientists to understand. After all‚ the creation of our Solar System took place billions of years before there

The Power of Solar Storms To Our Fragile Planet Natural disasters occur when least expected all over the world. Disasters affect countless lives and cost millions of dollars. Hurricanes‚ tornados‚ and tsunamis occur with such regularity throughout the world that society has developed warning systems and is prepared to rebound from these disasters as quickly as possible. One disaster that most people do not think about is solar storms. Research shows that solar storms have been documented since the

The Solar System My project is about the Solar System. The Solar System is made up of all the planets that orbits the Sun. The Solar System consists of moon‚ comets‚ asteroids‚ minor planets‚ dust and gas. Everything in the Solar System orbits or revolves around the Sun. The Sun contains around 98% of all the material in the Solar System. The larger an object is the more gravity it has. The Sun is the star at the center of the Solar System. After the sun is Mercury‚ the innermost planet in the
