The pressure to increase the consumption of clean, renewable energy has been growing all over the world, as a means to reduce the impact of the fossil fuels on the environment. Among many economically viable options available, the use of solar and wind energy emerges as promising alternatives.

In this line, a fresh, interesting article released by Earth Policy Institute, “Harnessing the Sun's Energy for Water and Space Heating,” gives readers a somewhat wide panorama on the application of this kind of energy around the world. The article shows that, yet neither widely used worldwide nor proportionally significant compared to the traditional sources of energy, the solar energy has been playing a significant role as a source of clean, renewable energy in some countries where it’s used for non-industrial purposes.
