Liquid air 'offers energy storage hope'. By Lim Kay Kiat

For full article click here!Recently Engineers have found a way to store the excess energy from renewables. Energy produced from wind turbines in the night can be used to freeze air. This reduces the amount of energy wasted as the wind turbine can be used even in the night. The liquid air can then be vaporised to air when the need arises to power turbines which in turn generate more electricity. This reduces Wrong-time electricity and increases efficiency without causing harm to the environment.
In my opinion this is a great step into protecting our badly damaged environment. Oil and fossil fuels which is currently our main source of energy in many countries. These forms of energy are not green and produce much harmful wastes and gases which harm mother earth. Burning of fossil fuels for example produces methane and carbon dioxide, two very harmful green house gasses which cause global warming. Thus with this new finding, we can now rely on another source of energy which is capable of producing electricity and yet not harm the environment. Furthermore, oil and fossil fuels are not everlasting, so one day we will use up all of it. Thus it is important we find new ways to produce electricity so as to reduce our reliance on fossil fuels and oil.
