On-shore wind

Wind power is an endless and renewable source of energy that has been used for thousands of years. It plays an important role in Umeå Energis investment in renewable energy and is in line with the company’s aim to be completely carbon neutral by 2018. In total, the municipality owned company Umeå Energi owns ten wind turbines, which provide significant climate benefits. These turbines are situated in the towns of Hörnefors, Holmsund and Robertsfors. Hörnefors wind power plant consists of eleven turbines with an output of 2 MW each from two different manufacturers, Vestas and Enercon.

The conversion of kinetic energy in wind into electrical power is known as wind energy. There are a number of ways in which this conversion can be done but the design dominating the market is known as the horizontal axis wind turbine (HAWT) with its archetypal three-bladed rotor. Wind energy is actually a form of solar energy; the temperature differences caused by the sun shining on the earth act, along with other factors, to cause large bodies of air, winds, to move across the face of the planet.

The Global Environment Centre Foundation (GEC) is an entity that supports the UNEP’s International Environmental Technology Centre (IETC), based in Japan. GEC is dedicated to the transfer of environmentally sound technologies, in both developing countries and countries with economies in transition. The foundation aims to contribute to Japan’s international efforts on the environment, sharing project collaborations as well as promoting Japan’s rich conservation knowledge and experience in developing nations.

Description of the project:

Sustainable Energy Africa (SEA) was registered as a non-profit company in November 2000 and with implementation of the new Companies Act in 2011. Sustainable Energy Africa promotes the development of an equitable low carbon, clean energy economy throughout Southern Africa. Through their work they promote the more efficient use of conventional energy, the transition to more sustainable energies such as solar and wind power, access to safe and affordable energy for all, and a holistic view of sustainable development.
 

Researchers at McGill University have developed a novel controller for Doubly Fed Induction Generators (DFIG) which are widely used in wind turbines. This controller allows for a robust decoupled sensorless control. This approach will enable continually optimal performance of the DFIG without the need for the operator to update the parameters of the unit. This approach can be easily implemented with DSPs and FGPAs and may also be applied to motor controls. Applications: As world energy consumption grows nations are faced with difficult and costly decisions to satisfy its needs.

Refrigerators and air conditioning units feature high on the wish lists of people in hot countries. The International Energy Agency (IEA) calculates that by the year 2030 the energy consumption for air conditioning in developing countries and emerging nations will be four times what it is today. It is often the case that the gases used as refrigerants are produced chemically. They are damaging to the ozone layer and accelerate climate change. By contrast green technologies use natural gases in the cooling process, are more energy efficient and can be driven by sun or wind power.

Nearly 22 percent of the world’s electricity is now supplied by renewable energy, and Central America is part of this global transition. The region is a worldwide leader in hydropower and geothermal energy, and most Central American countries are developing wind power projects. Yet the region is far from harvesting its enormous renewable energy resources to their fullest potentials, according to a new report from the Worldwatch Institute, The Way Forward for Renewable Energy in Central America.

The magnetic fields due to magnets are cut by the blades and causes an induced voltage as it pumps water to storage tank. It is an integrated technology for water and electric energy generation using integrated water and magnets for both pumping and electric generation.
