Many scientists, including Wilk, are concerned about this. Yet, where transportation needs are concerned, liquid fuels at the energy output level will be hard to replace. Therefore, increasing resource productivity could be one answer to the world's problem. Do whatever makes sense for what you are doing. Soft energy is energy which can be replenished, as compared to fossil fuels which can only be used once.
Wind is created due to the sun's inability to evenly heat the atmosphere of the earth.
The resulting air currents can be used to harvest energy. Wind power varies depending on the location. Off the East Coast of the US and in the Midwest are the best areas to intake energy from the wind. Wind can be converted into electrical energy by use of wind machines. Thirty-three percent of the available wind power in the US could be converted into electrical power.
