On-shore wind

  • Objective

    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.

  • Objective

    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.

    This case study examines important changes known to be either in the system or being considered at this time. Many aspects of the Egyptian energy sector are currently in the process of changing or change has been proposed. This includes, inter alia, elements relating to the costs of electricity transmission and distribution; new laws relating to the incorporation of wind power; pricing of gas, electricity and other energy carriers; whether wind components will be constructed in Egypt and how new wind plants will be tendered.

    These case studies in India establish that while the availability of good renewable energy resources is a key determinant, the other important factors behind the success of programs include favourable policy and regulatory environment, good grid network in the potential areas, land availability, users' awareness, year-round demand and established supply chains with reliable after-sales service.

    Objective

    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.
