Energy Electricity in Science How Does Solar Energy Work
Hi, I'm Steve Jones, and I'm going to explain how solar energy works. Now, solar means sun, so we know that the energy is coming from the sun, and we might think it comes as heat or whatever. In fact, we get all kinds of energy from the sun, but it is all radiation. Remember, outside the earth there is no atmosphere so nothing physically moves from the sun to us it is radiation. So, radiation from the sun which might be ultraviolet, it might be xradiation. It might even be infrared radiation which is heat radiation, or even radar very,.
Very like radio waves, so all kinds of radiation comes from the sun. Some kinds of radiation when they hit the surface of a silicon chip that is a thin slice of silicon crystal it sets up a voltage between the ends, so you get a voltage between the sides of the chip, and that voltage will produce a current. Now, this is quite small so you need quite a big silicon chip, or a lot of silicon chips. And when you look at a solar array as they call it you will see it is made up of lots and lots of small silicon plates. Each of them.
Produces a small current. Those currents are combined, and they can provide enough current to drive a household circuit set of circuitry up to about three thousand watts with a standard panel about one meter by one meter. So, solar energy, which is free of course, is available providing we can produce the silicon chips. The silicon chips are very expensive to produce, so although this energy is free the solar panels which are made to harness that energy are expensive. So, it works, but it only works as well as how much money you're prepared.
Energy 101 Concentrating Solar Power
Bjbj Take the natural heat from the sun, reflect it against a mirror, focus all of that heat on one area, send it through a power system, and you've got a renewable way of making electricity. It's called concentrating solar power, or CSP. Now, there are many types of CSP technologies. Towers, dishes, linear mirrors, and troughs. Have a look at this parabolic trough system. Parabolic troughs are large mirrors shaped like a giant U. These troughs are connected together in long lines and will track the sun throughout the day. When the sun's heat.
Is reflected off the mirror, the curved shape sends most of that reflected heat onto a receiver. The receiver tube is filled a fluid. It could be oil, molten salt something that holds the heat well. Basically, this super hot liquid heats water in this thing called a heat exchanger and the water turns to steam. The steam is sent off to a turbine, and from there, it's business as usual inside a power plant. A steam turbine spins a generator and the generator makes electricity. Once the fluid transfers it heat, it's recycled and used over and over.
And the steam is also cooled, condensed and recycled again and again. One big advantage of these trough systems is that the heated fluid can be stored and used later to keep making electricity when the sun isn't shining. Sunny skies and hot temperatures make the southwest U.S. an ideal place for these kinds of power plants. Many concentrated solar power plants could be built within the next several years. And a single plant can generate 250 megawatts or more, which is enough to power about 90,000 homes. That's a lot of electricity.

Federal Tax Credit for Solar Energy TurboTax Tax Tip Tutorial
Hello, I'm Jeremy from TurboTax with important news on how you can reduce your tax bill and protect the environment at the same time. Have you installed solar powered equipment in your home this year Or are you considering it If so, the federal government will reward your environmentally conscious home improvements with a tax credit equal to 30 percent of your purchase and installation costs. There is no maximum on the amount of credit you can claim. Essentially, the credit works like this. If you spend 10000 dollars to buy and install solar panels on your roof,.
Your credit will equal 3000 dollars. If at the end of the year, you owe 5000 dollars in taxes, the credit reduces your tax liability to 2000 dollars. If you haven't purchased the solar powered equipment yet, don't worry. You have until 2016 to do so. There is, however, one notable limitation to the credit. It is only available for improvements that you make to your main home which is generally your principle residence where you live for most of the year. You can also increase your tax savings by claiming similar credits for energy efficiency improvements.

Why Teslas Powerwall Battery Is Amazing
All of humanity just won a really important victory in our battle to lower the CO2 emissions that are causing climate change. Tesla CEO Elon Musk introduced the world to the Powerwall, a wallmounted battery for your house which aims to accelerate our transition to clean solar and windpower. Before the powerwall, there was no way to store the energy generated from the panels that capture sunlight on our roofs. So during the day they could give you the power you needed, but at night, you had to rely on the grid, which gets most of its.
Electricity from coal, natural gas, and nuclear reactors. There had been some early home batteries out there, but nothing that was nearly this affordable. But Tesla, which has built thousands of large, lithiumion battery packs for its growing electric car business, was able to produce a similar battery for buildings at a scale that dropped the production costs dramatically. The lowest capacity model will cost just $3,000. And this is the first generation of the productbefore Tesla's even completed building its massive new Gigafactory, or any real competitors have entered the market, events that will surely push the price down.
Even further, while increasing the energy storage capacity of the Powerwall. Here's how it works. When the sun is out, solar panels will power your house and charge the Powerwall at the same time. And when the sun goes down, this charged battery will kick in to meet most or all of your electricity needs until the sun comes back up again the next morning. This is gamechanging. More and more people will go completely offgrid. Every building whether it's a home, office, business, warehouse, factory they can all.
Install solar panels and some Powerwalls and instantly see their fossil fuelgenerated electricity needs drop significantly. Not every building will be able to go completely solarpowered, but most will get pretty close, especially as our appliances become more and more energy efficient. And it gets even better. The powerwall will be connected to the Internet and the rest of the energy grid. Here in Southern California, and most other heavily populated places, the electricity company charges us a lot more when we use electricity during peak timethat's in the afternoon and early evening when the temperatures are warmest and most of us are.
Home and still awake. The Tesla battery is smart, and knows when electricity is cheapest, so that's when it will draw from the grid to charge itself. And then, during peak time when you need electricity, the battery will power the house. Sometimes, you'll be able to sell back unused power to the utility company during peak time to even make a profit. It's basically going to make each individual building its own power station. Overnight, Tesla seems less a futuristic car company, and more like the man who inspired the company's name, a revolutionary electricity engineer named Nikola.
