Eco Friendly Solar Energy.
Solar energy is a free source of energy and there are several promissory eco friendly techniques and technologies being developed. The sun produces light and heat, and humans have harnessed it since ancient times. Solar radiation is the most important renewal energy source available for human activities, along with wind, wave power, hydroelectricity and biomass. Only a minuscule part of the available solar energy is actually used today.It has being said that the potential uses of solar energy are only limited by human ingenuity. There are several uses available now for solar energy like water heating, water purification, day lighting, natural illumination, solar cooking, space heating and cooling, and solar architecture among others.
One of the most eco friendly methods used in construction is passive solar building design or solar architecture. It is a professional knowledge that uses several techniques and strategies, to use the natural solar energy to illuminate the building and regulate its temperature, without the use of mechanical or electrical devices. It is based on millenarian and scientific knowledge. It doesn't need human generated energies and so it doesn't produce any kind of contamination.
In passive solar building design, it is vital to analyze the local climate. Solar architecture puts detailed attention on sun inclination through the year, northern and southern solstices, wind directions and speed, altitude, relative humidity, shadows produced by other bodies like buildings, trees or mountains, local wind currents generated by skycrapers, and other factors that affect the micro climate around the building. The huge advantage of passive solar building (solar architecture) is that it relies on solar energy and natural processes. Solar architecture doesn't need energy generation, being an excellent eco friendly solar energy use.
Eco friendly solar energy generation, relies on photovoltaic generation and heat engines. Solar panels also known as photovoltaic panels, can be used for producing electricity in houses and building of almost any kind. It is a great ecological technology, but it is still expensive. There are also solar panel plants that generate a lot of electricity and then distributes it to cities and residences.
