Solar Energy – Most Popular Alternative Energy Source

October 30th, 2012 in Alternative Energy by 0 Comments

Solar energy is quickly becoming one of the most popular alternative energy sources. The reason for its popularity is that it is comparatively cheap to purchase and install and it can be used to power a person’s home directly or to collect energy to sell back to the power company. It also can be discreetly positioned on the roof so that in many cases it may not even be visible from the road.

Solar energy works by simply collecting the sun’s rays which basically consist of a complex array of nuclear bi-products which can then be converted into electrical energy. Solar energy is collected at both the private level and in large solar farms which have moveable panels to collect the lion’s share of sun at any time during the day.

Solar energy has great potential as a near-free energy source on Earth but it is also used in space as a free energy source for unmanned spacecraft. Once ejected from Earth’s atmosphere, these spacecraft can harness the practically limitless power of the Sun and other suns as they venture across the stars. Of course this means of solar sail travel is quite slow; a long enough timeline will provide tremendous results.
