Wind Energy is the energy found in the wind that is grasped by Renewable Energy Systems Technology (REST) in order to generate power for human benefit. Wind turbines are the REST used to collect the wind resource and generate power. Today, wind turbines are used to generate electricity from the wind. There are two types of wind turbines, the horizontal axis turbine which is the most common one and the vertical axis turbine. The horizontal wind turbine is the most efficient and cost effective. Most of the wind turbines used for electricity generation are of this type. Wind turbines can be found in many sizes and outputs, from small battery charging turbines to the largest machines used to supply electricity to the grid.

What is Wind Energy?
Tuesday, August 25th, 2009What is Solar energy?
Tuesday, August 25th, 2009Solar energy is the energy of sun light. The temperature of the Sun’s surface reaches to a value of approximately 5,762 K. The Earth’s perimeter of 40,000km results in an intersected sun power of 174,000 TW. Attenuation by the atmosphere results in a peak intensity at sea level of around 1 kW/m2, giving a 24 hour annual average of 0.2 kW/m2 and a 24 hour annual average power of 102,000 TW. This commands the environment and maintains the life support system of the Earth’s ecosystem and all forms of renewable energy with the exception of geothermal energy. The solar energy reaching the earth’s surface surpasses 10,000 times the current global energy demand.
What is renewable energy?
Tuesday, August 25th, 2009Renewable energy is the energy that is grasped by the earth’s abundant natural sources. Renewable energy can be harnessed with the appropriate use of technology to satisfy the human energy needs. Solar, wind, wave, tidal, bio energy are termed as renewable. These renewable energy sources can be classified as ‘active’ or ‘passive’. Active renewable energy sources are renewable sources which with the use of renewable energy systems technology (REST) can generate power and heat to satisfy the energy and heating demands of buildings. Passive renewable energy sources are the renewable sources which with the use of static building elements can enhance the natural ventilation and the heating of a building.
