Green Lighting – Kid-Friendly Solar Energy Info

Understading about Solar Energy From the Dept of Energy: It’s a bit cloudy

Affinity for solar energy as an energy source rises and sets along with the income tax credits that fuel its growth. Because I am in essence a kid at heart, I visited the Energy Kid’s Page of the Energy Information Administration to learn more.

The Energy Information Administration (EIA), created by Congress in 1977, is a statistical agency from the U. S. Department of Energy. “Our mission is to give policy-neutral data, forecasts, and analyses to promote sound insurance plan making, efficient markets, and public understanding regarding strength and its interaction with the economy and the environment. ”

The Energy Kid’s Page starts off in a friendly manner in a way that perhaps I could understand:

The sun has produced energy for quantities of years. Solar energy is the sun’s rays (solar radiation) that arrive at the earth.
Some of this pros and cons of solar energy is converted to heat, used to heat water and building interiors.

So far, so good.

Power from the sun can be converted to electricity in two ways:

Photovoltaic (PV devices) or “solar cells” – change sunlight inside electricity. PV systems are often used in remote locations that are not connected to the electric grid. They are also used to power watches, calculators, and lighted road signs.
Solar Power Plants – circuitously generate electricity when the heat from solar thermal collectors is needed to heat a fluid which produces steam currently in use to power generator. Out of the 15 known solar electric power generating units operating in the United States at the end of 2006, 10 these are in California, and 5 in Arizona. No studies are being collected on solar plants that produce a lot less than 1 megawatt of electricity, so there may be smaller solar plants in a number of other states.
With childlike wonder, I clicked further, wanting to learn how energy-efficient, renewable solar energy can help lower fossil-fuel-generated electricity (half of which comes from burning coal, which will creates the 104 tons of mercury annually we have often the pleasure of breathing, drinking, and eating).

So I dug into the Photovoltaic Section. Without warning or proper disclosure, The power Kid’s Page sent me back to college for my very own PhD in electronics. (Guys: Seriously, do you really think your personal Kid Page is kid-friendly?! )

With quick googling, I found an online university and enrolled, studied night and day to get four entire weeks, got my PhD, and now are delighted to give you this kid-friendly explanation of solar energy.

We are going to shine a light on photovoltaic energy and the three sorts of solar power plants.

Photovoltaic Energy

Photovoltaic energy is the change of sunlight into electricity. A photovoltaic cell, normally called a solar cell or PV, is the technology familiar with convert solar energy directly into electrical power. The solar cell is often a nonmechanical device usually made from silicon alloys.

Sunlight features photons. Photons have energy. The solar cell obtains slammed by photons and absorbs some of them. Others inflatable bounce right off like basketballs or pass through like ghosts. Often the absorbed photons knock electrons out of place. Electrons are classified as the stuff that electricity is made of. The electrons bubble up to the floor of the solar cell. This movement to the surface makes an imbalance. When you hook up a wire from the photo voltaic cell to an outside battery, you create a path the fact that electrons will follow. That flow into the battery is energy.

Online Movie Rental – Three Ways to Rent Online Movies

The world of online movie rentals has exploded with the poor market. Renting movies on-line is relatively simple and those venues that can come to mind are renting the DVD online and the organization posting the movie to you, downloading the movie to your computer and browsing from your computer, and just watching the movie from your computer watch. Whichever way you choose to rent an online movie, you will truly be satisfied with the final product.

There are a number of organizations that require special with them in order for them to ship their DVD’s to you. There is a minor monthly fee for this membership based on the number of movies that you really think you may want to rent with the company. Once you have decided which inturn option you want to go you simply pick out a movie and keep the item for as long as you like. There are no late fees and the firm will ship your next movie to you once you have sent in another movie.

Some of the same organizations have memberships where a homeowner is able to download a movie to their computer and watch the movie from them PC. These memberships also charge a nominal price for their services and you don’t have to send in any movies to acquire the next one. This option allows you to have the movie and watch them whenever you like.

This last option includes watching a movie inside of personal computer without actually downloading the movie to your hard drive. This is probably the easiest of your options and has minimal membership fees. Reviewing a movie from your PC only requires you to log into your website and then get set to watch your movie. watch movies online visit on 123moviehub
