Ground mounted Solar Farms are questionable.

It is widely known that multibillion companies are massively investing in solar energy. Especially Internet companies (Google, Yahoo, 1and1, etc.) have huge demands for energy to feed their decentralized server systems. Experts estimated that in ten years from now this modern telecommunication (internet, clouds, videos, email etc.) require worldwide 1963 Billion kWh. This is three times more than the current entire power consumption of France, Germany, Brazil and Canada together (Greenpeace). With this numbers in mind it is understandable that these companies like to reduce their energy costs in the long run with alternative energies.

However alternative energy doesn’t mean it is “green”. Especially ground mounted solar farms (the preferred solution of these companies) consume a tremendous amount of land and produce substantial amounts of run-off. Typically the development starts with clear-cuts of forests, elimination of native environments or transforming farm land. After the development is done sometimes vegetation is brought back. Typically low growing grasses that require regular maintenance with sheep, weed covers, mulch, gas powered mowers and chemicals.
Once this expensive maintenance is not done consistently the performance of the system will suffer and eventually completely fail.
Ground remote Solar Farms.
Solar arrays installed on already impervious areas will reduce the land consumption dramatically. Also being less addicted to Facebook , IGadgets, PC, or smart Phones can actually reduce the energy need -our impact- without losing contact to friends and still making new friends. A hand written note in a personal calendar can be more environmentally friendly than connecting to clouds and email programs.
Since there are already enough existing roofs, parking lots, rail road tracks and roadways that could be covered with Solar and also combined with extensive green roofs would create recognizable stormwater reduction, perviousness and last not least power. This combined technology is available since decades but many Architects, Engineers and developers seemed to be blinded by the sun while the supposing green industry takes out one piece of fertile land at a time and taking away nature’s most advanced solar panel – the plants that are surrounded by a natural sponge.
No additional land use and hardly any maintenance on extensive Green Roof / Solar combination with the well-engineered Sun-Root ™.
