Solar Energy Applications
Solar energy technologies use energy from the sun to produce heat, light, hot water, electricity, and even cooling, for homes, commercial and industrial.
There are a variety of technological applications that have been developed to take advantage of solar energy. Technology can be read further below.
Photovoltaics System
Solar cells work by converting sunlight directly into electricity. The electrons in the semiconductor material, the material used to capture sunlight, will move when the sun’s energy in the form of photons hit it. Solar energy is forcing the electrons to move, occur continuously, and consequently there is also a continuous electricity production. Process, which turns sunlight (photons) into electricity (voltage), called the photovoltaic effect.
Solar Cell Module
Solar cells are usually organized into modules that each module can consist of 40 solar cells. Some modules can be arranged to form a PV line fitted with a fixed angle facing south. Or even could be placed in a sun-tracking device, to get more solar energy throughout the day. Several rows of PV could produce enough power for a house. As for industrial applications or power companies, hundreds of lines of PV can be linked to form one large PV systems and sufficient to meet the electricity needs.
Thin Film Solar Cell
Thin film solar cells use several layers of semiconductor material with a thickness in the micrometer scale. Technology allows to create solar cells integrated into rooftops to the skylights. Even solar cells are designed for applications having the same power with actual roof.

Wind Generator Plans
Executive Summary about Wind Generator by Donald Whitehead
Renewable energy! There is renewable energy for homes for instance, it can range from solar power by use of solar panels, or wind power by use of wind generators both of which there are plans for. This article’s main focus is on wind generators and wind generator plans. A wind generator generates electrical power using the wind as it’s power source. Coupled with solar panels wind generators are the #1 pick for renewable energy for a large array of reasons. Wind generators, unlike many electrical projects, are very basic and can be assembled and installed by most home owners themselves. You can then purchase adequate solar panels as well as the right generator for your wind generation build.

Taiwan Sustainable Tower by Steven Ma
Cooperation with San Liu, Xinyu Wan and Emre Icdem, Vienna-based architect Steven Ma has proposed a very innovative super thin twin towers for Taiwan that will be used to demonstrate Taiwan’s past, present and future. With a height of about 360 meters, the sustainable tower features an observatory deck and sky-gardens at an altitude of 350 meters.

Wind Generators As Your Energy Source
Many people have started to install wind turbines, wishing to lower their bills for electricity, and in some way help make the environment safer while saving on non-renewable sources of energy. You need some knowledge before taking your various tools and purchasing your other needs for making a wind generator.
Whether you are installing a self-made or a commercial generator, you need to make sure you have the optimal location for it. You will need a place where trees and buildings are not obstructing the air flow.
If you happen to be living on a farm, obstacles probably aren’t a factor and the view of your neighbors is no concern. However when you live within the boundaries of a city, it can be a lot more difficult to install a wind generator.
The wind towers are so tall that they can be dangerous in storms and high winds, so this could impact the community. Consult not only your local authority but also your neighbors before putting one on your property. Of course you always need to consult for the county or city codes.
You have a few choices for the exact spot for your wind tower. The top of your house could be a great location or if you own enough land you can set the tower away from the house. In a small town, numerous wind generators can be installed in a common area for the whole community. So everyone can benefit from lower utility bills, and you do not have to worry about the towers getting blown over in a storm.
You could also look into other forms of renewable energy to run your house. If you have enough sun in your area, consider installing solar panels as a back up for your wind generator.
You can read more from Steven C. Jones on his blog about wind generators and renewable energy.
