Green Energy
Going Green and Becoming Rich
To paraphrase President Barack Obama in one of his State of the Union Address, the nation that becomes the leader in clean energy economy will become the leader of the global economy. How very true, indeed, especially when one considers that the renewable energy industry and its allied industries are growing by leaps and bounds even in the worldwide recession. Any nation that can supply the increasing demand for all things related to renewable energy from the solar panels to the wind turbines will become rich by going green. At present, it is China that is cashing in on the green revolution, with factories spread out over the rural and urban areas dedicated to the production of renewable energy equipment and materials. This is very ironic considering that China is not exactly a nation that environmentalists will award the most eco-friendly in the world, far from it. Then again, the United States is guilty of many dastardly acts against the environment, too. Proofs of this fact are the following statistics of how China fares in comparison with its nearest competitor in the renewable energy industry. First, China and the United States are the top two producers of greenhouse gases, with Russia, India ...- Bookmark :

Solar Options Cheaper Than You Think
Many people don't have solar power because they think it is incredibly expensive. While you may want to start doing the right thing environmentally, you probably don't have the thousands available to purchase a photovoltaic system for your home. Well, maybe you don't have to spend thousands on the solar options that you need. I happen to know a couple, Pam and Phil, who are both teachers. One is a principal and the other happens to be a really smart English teacher. Of course, they don't make a ton of money, and they have a baby on the way. Instead of just throwing the idea of solar power right out the window, they sat down, did the numbers, and did a lot of research too. One option they had was to put an entire system on their house and get rid of using coal and the other option allowed them to get rid of coal while paying nothing. Take a guess which option they decided to go with. The option available is known as solar leasing. If you can't afford to pay for a system outright, this option allows you to lease the system you need and it makes a great alternative ...- Bookmark :

Understanding Energy Subsidies
Not sure what energy subsidies actually are? Well, you'll find that they are something that is wielded as a champion of energy technologies that are favorites against those technologies that are competing. Those that really support nuclear energy and fossil fuels try to say that those energies such as solar and wind and other types of renewable energies can't stand up by themselves. Those who advocate these renewable forms of energy then argue that these other types of fuels have been supported by the government for some time. What you need to understand when it comes to energy subsidies is that every form happens to be subsidized. There are not any types of energy, including nuclear, renewables, or any others, that can stand on their own without having loan guarantees, tax preferences, or even research grants on their behalf. Of course, this really doesn't have to be a bad thing. The biggest questions is which problems are we dealing with when it comes to energy and in order to solve them, what energy subsidies need to be used? Trying to pin down what really is and is not a subsidy is not that difficult. There really isn't a definition of subsidy that ...- Bookmark :

Secrets behind Wind Turbine Technology
In some places of the world, wind turbine power accounts for ten percent of the total electricity consumed. This is, sadly, a very small fraction of the power generation and consumption coming from coal plants as well as from solar panels. Still, it is progress that we should welcome for the simple reason that taking it one step at a time is better than taking no steps at all in the right direction. To take these small but important steps towards cleaner electricity through wind power, it is important to know about the secrets, open these may be to anyone interested, behind wind turbine technology. Turbines in Relation to the Generation of Electricity Think of your ordinary electric fan - it generates wind by using electricity. Now think of the wind turbine although in a reverse mode - it generates electricity by using wind. The technology behind wind power can be summed up as simply as that statement. But of course, electricity generation is hardly ever that simple. Let's put it this way for the non-techie amongst us. The turbine blades are designed so as to capture the maximum amount of wind, which will cause them to rotate. In turn, the rotation spins the ...- Bookmark :

Solar Power Inverters
One of the best things about solar power is its relative simplicity. Add that to the independence you get and the clean renewable energy that comes from it, and you've got a winner. After all, you need a solar panel or panels, wiring, a regulator/charge controller, an inverter, and in some cases a deep cycle battery. The inverter is one of the most important, but also one of the most frequently overlooked components. It's what helps you turn energy from your solar panel into usable power. That's because solar panels usually put out twelve or twenty-four volt direct current. There are a number of camping appliances out there that can use this form of power, and many older off grid homes use entirely DC devices, but most home appliances need one hundred ten to two hundred forty volt AC (alternating current) power. Inverters are what helps you make the chance from DC to AC and ramp up the voltage. DC current flows continuously in one direction, while AC alternates in direction. The oldest electrical installations ran on DC, but greater efficiency of transmission is gained by using AC. That's why, despite the fact that many appliances actually run on DC, they receive ...- Bookmark :
