Renewable energy is crucial to halting the climate crisis. Wind, water and solar – we need all the renewable energy we can get. Over the last few years, wind power on land has evolved into a modern technology that is profitable without government subsidies. Right now, Norway continues to use considerable amounts of oil and gas. If we are to succeed in obtaining our climate objectives and in phasing out oil and gas, we need more wind power.
We have all felt the wind on our body. The ice-cold wind that drives us indoors in the winter and the mild, warm summer breeze that fills our sails in the summer. But what actually is wind?
Put simply, it is the movement of air in the atmosphere that occurs when there is a difference in pressure between bodies of air. Such differences in pressure occur as a result of the force of gravity or the sun’s warming of the Earth’s surface. Cold air is heavier than warm air so the force of gravity pulls cold air down, creating high pressure at ground level.
The sun is another important factor in the creation of wind. It radiates massive amounts of energy which hit the Earth at all times. Heating of the Earth’s surface creates warm air above the ground, which then rises to create low pressure at ground level. Physics dictates that differences in pressure must be evened out and this occurs by bodies of air circulating from areas with high pressure to areas with low pressure. This circulation, or movement of air, is full of potential energy which can be harvested by the use of wind turbines such as those on Midtfjellet to produce wind power.
We all share a common responsibility for our environment. Both locally and globally. It is quite clear that fossil energy sources must be abandoned if we are to pass the Earth on in good condition to coming generations. Wind power is an obvious means for achieving this aim. Wind power is renewable energy, a source of energy that will never run out.
In order to bring about sustainable development with wind parks, we must also be willing to take the necessary steps so that construction can be undertaken. We see the benefits as much greater than this, however: we have established a wind park on Midtfjellet which, in terms of land use, is concentrated and well-utilised, and we have developed an infrastructure which makes the mountain area readily accessible to new user groups.
Not least, however, it means that those who come after us may inhabit a cleaner Earth. As a supplier of renewable energy, we make a difference!
