There are different types of inverters for solar use (string, central, micro). If you’re hoping to install the solar PV system yourself, selecting the best inverter will require serious research and careful planning. If you work through a professional solar installer, on the other hand, the company should help take care of inverter selection for you.
A wind turbine is made up of two major components and having looked at one of them, the rotor blade design in the previous tutorial, we can now look at the other, the Wind Turbine Generator or WTG’s which is the electrical machine used to generate the electricity. A low rpm electrical generator is used for converting the mechanical rotational power produced by the winds energy into usable electricity to supply our homes and is at the heart of any wind power system.
When power flows from the generator to your house, electrons get mixed together on the wires. You can't specify which electrons you get, but you can make sure that your money goes to support clean, sustainable generators, which has the effect of making the whole system "greener". To do this, you will need to look closely at utility marketing claims and materials. To ensure that the claims are truthful, many states now require disclosure labels, just like the nutrition labels on food packages. But don't hesitate to ask for more information directly from potential suppliers, including the percentage of power derived from each fuel source and the level of each of the above emissions compared with the regional average.
I ask Gore about the lessons he takes from Georgetown. “I think it’s important to pay attention to a CPA who becomes a mayor and takes an objective look at how he can save money for the citizens of his community, even if it means ignoring ideological presuppositions about fossil energy. Especially when the mayor in question is in the heart of oil and gas country.”

As of 2014, offshore wind power amounted to 8,771 megawatt of global installed capacity. Although offshore capacity doubled within three years (from 4,117 MW in 2011), it accounted for only 2.3% of the total wind power capacity. The United Kingdom is the undisputed leader of offshore power with half of the world's installed capacity ahead of Denmark, Germany, Belgium and China.
Between maintenance and repairs, it would greatly help and keep your cost down if you can do some of the work yourself: Being able to safely tilt the turbine tower up or down will save you money. Understanding how the turbine works, how to stop it safely, how to trouble-shoot at least the minor issues can keep you in the black. We understand that installing a wind turbine is not for everyone. In fact, towers are dangerous, and for a good installation the devil is in the details. An experienced installer can make a real difference in putting up a turbine that will work better, and be more reliable over time. We really encourage you to have a professional installer to do the initial installation. However, throwing up your hands and calling your installer for routine maintenance, or every time there is a minor issue, will likely make you an unhappy wind turbine owner (even if it is your installer’s dream).
Even with plans to grow as much as 80 percent over the next five years, the city expects to have plenty of energy from these renewable sources. (To be sure, about 2 percent of the time, the Georgetown utility draws electricity derived from fossil fuels. Ross says the city more than compensates at other times by selling excess renewable energy back to the grid—at a profit.)

Many residential PV systems are connected to the grid wherever available, especially in developed countries with large markets. In these grid-connected PV systems, use of energy storage is optional. In certain applications such as satellites, lighthouses, or in developing countries, batteries or additional power generators are often added as back-ups. Such stand-alone power systems permit operations at night and at other times of limited sunlight.
