New Scientist: In the face of climate change and global warming, wind power is becoming the power source of choice for many countries around the world. Although fossil fuel remains relatively cheap, improvements in wind turbine design and wind farm layout have been increasing wind power’s efficiency and lowering its cost. And because many governments favor renewables by imposing carbon taxes on fossil-fuel plants, wind farms are beginning to be seen as a safer long-term investment, according to Guy Turner of Bloomberg New Energy Finance, which has offices worldwide.

Because people abuse the source of the earth, our environment has been polluted, which causes the global warming. Now, more and more scientists are finding the alternative source to create energy. I am so happy when I saw this news. Using wind power means people have realized the importance of environment and have began to gain a “green” earth. For physics, scientists should design the devices for wind power, which need calculate the force of wind or create a sensor for wind power. I think it is a good example for applying physics.
