A number of recent studies convincingly demonstrate that wind energy will not save us: neither from global warming, nor from a high mortality rate, much less from the existing system merciless energy consumption killing the planet. Photos from open sources
So, fact number one: even a massive transition to use wind power will not help reduce greenhouse gas emissions so much so that it can positively affect the climate of the planet. More Moreover, such a transition can only aggravate the situation.
Here’s what a study published in September says about this in the journal Nature Climate Change:
Turbines create air resistance, which ultimately reduces the speed and power of the wind flow. Due to this effect as the number of turbines increases, the amount of energy produced will be grow, but only until a certain point, until the wind slows down so that the marginal utility of the new turbines is equal to to zero.
If the windmills will produce energy in the amount of current global demand for it, their work may cause a change Earth’s surface temperature by 0.1 degrees Celsius.
Another study published in Nature’s journal February showed that the work of wind farms in Scotland leads to increase carbon dioxide emissions:
Wind farms are usually located on hillsides where peatlands prevail.
Peatlands are a source of carbon in Europe, comparable in size to the rainforests of America. Peat bogs also absorb carbon, like trees and plants, only in a few times more intense.
UK carbon deposits estimated 3.2 billion tons.
Construction of wind farms and related infrastructure damages peatlands, causing a huge amount of carbon enters the atmosphere and warms the climate even more.
Another study published in February in a journal Environmental Research Letters, contains a detailed analysis the above effect of slowing down wind speed and rotation turbines. The discovery of this effect significantly reduced forecasts wind turbine performance:
Initial Wind Farm Performance Estimates (2-7 watts per square meter) did not take into account the effect of deceleration of rotation turbines. In fact, given this effect, the peak the performance of wind generators will be 0.5-1 watts per square kilometer.
If we covered the entire surface of the Earth with a network of wind farms, their energy potential would be huge, over 100 terawatts. However, our climate models show that the impact on winds around the world would be so serious that the climatic effect from this would be more powerful than from doubling carbon dioxide emissions into the atmosphere, – the author emphasizes research physicist David Kate.
For more convincing, we give an excerpt from another research, which shows that windmills placed on water, can break like matches under the pressure of medium-sized waves:
“If you don’t solve the problems caused by the waves, all projects wind farms will fail, ”John warns Gru (Norwegian scientist who discovered the devastating effect waves in a collision with surface structures – Mixednews) Apollon Magazine.
Waves spoil the life of not only wind turbines, but also oil platforms. “But if in the case of oil platforms a problem can be solved by strengthening the platform, do the same with turbines just economically unprofitable, “says John Gro.
And finally, let’s not forget that wind generators pose a threat to birds:
Collision with turbine blades in a wind park North Sky River Wind in California caused the death of a golden eagle (another name – the golden eagle – Note Mixednews).
Wind energy, just like solar energy, is not a panacea for energy hunger. The only way out is reduction in consumption and the transition to closed, local economic systems that do not need a neighbor’s energy resources to exist.
In other words, the key to solving the problem is total destruction. global economic system.
