Solar power

Solar energies in Extremadura

All the technology will not spare us a simple fact: we live on earth thanks to the sun radiation. For centuries we have transformed (or, rather, used the ability of the plants to transform) energy in matter through photosynthesis, and in fact the plants are just solar panels that have a specific speed in that role of sun energy conversion. Going for more lucrative crops is just keeping depending from the sun. What technology brings is the ability to transmit that sun energy without transforming it into matter (heating wood, food or other products), but just as electricity. But solar panels do not grow by themselves, demand a power grid to transmit their produce, and we are not as used to see them on the landscape. Albeit sheeps seem to appreciate their shadow…

Energy (2) Sun

The Charanka solar park, in the Indian state of Gujarat, covers a 20 sq km area; it should attain 1 GW of production capacity when completed. From January to October 2012 the electric output was 686 GWh, so taking into account a per capita yearly electric power consumption of 616 KWh in 2010 according to the World Bank, would serve for a year more than 1,11 million Indian citizens (or slightly more than 111.000 Spaniards, 88.700 French, or 51.000 persons from the US…). It concentrates a set of solar panels from different firms.

The project is associated to an hydraulic system whose canals will be at least partially covered by solar panels, as to reduce the evaporation losses, relevant near the dessert.
