As you may already know that the Netherlands is one country in the world that has a long history in renewable energy, examples of which can be seen with certainty is that the famous Dutch Windmills.
The position of some of their territory is below sea level which makes them have to innovate in order not to sink, and the results were successfully created the Dutch windmill technology that addition can be used to pump sea water out in order to form a new, more extensive land (polders) and can be used as well as auxiliary facilities in agriculture and industry.
Such as the manufacture of paper, honing timber, remove the oil from the seeds, and grind corn (Warokka, 2011) . Along with the development of technology, modern Dutch used windmills as a source of renewable energy, even by Daily News article in Dutch, in 2011 the production of electricity generated by windmills rose 5 percent from the previous year.
In addition to innovation “the Dutchmen” with windmills, one of their creativity as well as in renewable energy in agriculture is the photovoltaic greenhouse. Photovoltaic greenhouse which echoes coming from the Dutch Wageningen University is widely adapted by other countries such as France and Spain. Sure you ask if it’s photovoltaic greenhouse? and in you imagine envisaged a greenhouse which usually is a place for cultivation but using solar panels.
You are not completely wrong, can be seen in addition to simple image of this greenhouse Photovoltaic, PV-greenhouse is a place other than greenhouse cultivation can also be used as a source of renewable electric energy. Solar panels are used to capture and convert sunlight into electrical energy in pairs at the greenhouse roof facing south. This type of greenhouse is one of the innovator and researcher numbers one a dutch named Piet Sonneveld. He calls this type of greenhouse, with the title The Fresnell greenhouse.
Unusual type of greenhouse is acknowledged to be one source of food and energy sources at the same time. One solar panel 1.5 x 1 meter size can produce about 120 watts and this panel can be used to illuminate the lamp 12 bolham, and approximately 0.4 ha of land can produce more greenhouse than 5 tons of tomatoes or peppers. So, theoretically, if we have a 0.4 ha PV-Greenhouse, with 128 solar panels we can get tons of tomato plus 5 15:36 Kw [iii] which can illuminate a village with several heads of household.
From the description above it can be concluded that the technology in agriculture can be a sustainable source of renewable energy. Reflecting the Dutch technology, can be used as a reference for managing an agricultural area that is not only able to produce food that is the main product but at the same time a useful source of renewable energy and sustainable.
